My Reasons Why Homework Isnt a Good Idea Essay Example for Free
My Reasons Why Homework Isnt a Good Idea Essay Go to school for seven hours, go to practice for two hours, go home and do homework until you fall asleep. That is the life of most high school students. We are all so busy with schoolwork, clubs and not to mention our outside of school life. Homework is just a source of stress and anxiety for a lot of busy students and takes a lot time out of busy schedules. I think this is a worry that could be eliminated. Student athletes everywhere know what I mean when I say that when you have away games, you do not want to think about coming home to do homework on an already late night. It is tough enough to finish all of the homework that teachers assign when all you have is a regular practice. As you get older and take harder classes, the homework load and the amount of tests and quizzes also increase. Studying for these also take time and most of the time you just feel rushed to get through everything you have to do that night. Therefore you donââ¬â¢t retain all of the information that you tried to cram into your head. I know of some people who really canââ¬â¢t finish all of their homework at night either because they have so much to do or they prioritize between studying for a big test or getting a good grade on a homework assignment. Homework is an added on stress to young people who participate in sports, clubs, and band and that stress can be taken out in destructive ways. Another reason I think that students shouldnââ¬â¢t have as much homework as we do is because we already go to school five out of seven days of a week for seven hours a day. We go to school for a reason and that reason is to learn but we shouldnââ¬â¢t have to bring schoolwork home when we already have been to school that day. Also, most of the information we learn will never be applied in our lives or be helpful to us. I can understand the occasional paper to write or story to read and definitely studying for tests, but I think we just need to learn what we will actually use in life rather than extra information. Itââ¬â¢s impractical for teachers to assign homework about things that I will never hear of or use again. It seems like a waste of everyoneââ¬â¢s time. My last argument is that most students donââ¬â¢t get enough sleep because they are so busy all the time. The students that participate in something where they have practices or obligations that they have to attend to are usually the ones that actually do all of their homework and studying, therefore get less sleep than they are supposed to. Adults always say you should get eight hours of sleep if not more every night but that is all but impossible when you have so much to do. I know personally Iââ¬â¢m lucky to get seven hours of sleep on a good night and I always wake up exhausted. Lack of sleep is a very serious problem for people my age. Also, if you would be able to get to more sleep at night then they most likely wouldnââ¬â¢t fall asleep in class or have such a hard time staying awake. If you are more alert in class you will also get more out of the lesson and understand the material better. There are so many reasons that homework isnââ¬â¢t a good or effective idea. Students donââ¬â¢t get as much sleep and have a hard time staying awake in and out of class. They wonââ¬â¢t get as much studying time for major tests and wonââ¬â¢t retain as much information when all they are trying to do is get everything that they need to do that night done. Finally, we already go to school for large amounts of time and do a lot of work there and then they try to make us do even more outside of class. School is basically like a full time job for students and if you participate in extracurriculars than it just seems like everything gets so clustered in your life. I believe homework is an unnecessary stress that can be eliminated for the young people today.

The Causes Of Over Sleeping English Language Essay
The Causes Of Over Sleeping English Language Essay What causes over sleeping you ask? Over sleeping is caused by many different factors. Things such as not getting enough sleep and not setting your alarm clock to wake you up can contribute to you not waking up from your sleep when it is time to. Many people contribute this to factors that may be deemed medical related and may actually not be medical related illnesses. While many people suffer from sleep deprivation or sleep loss, occasionally there are those who suffer from getting too much rest. Normally this would not be a problem but you have to think about this issue from the perspective of how it affects your career or your home life. Lets take for instance if you are a working person and you have a career or just a job where your employer depends on you being to work on time. A pattern of being late may get you reprimanded or even worse fired. A case of oversleeping on added to an already pattern of tardiness and or lateness for other reasons can be disastrous. Or take for exam ple you drop off your kid at your parents house and they have somewhere important to be and you dont wake up on time. This will cause a real problem for you with your parents. So this can be a problem beyond just getting way too much rest. Having a good alarm clock is essential to keeping yourself from over sleeping. You need on that is loud or audible enough to wake you up on those mornings where you just dont feel like getting out of the bed. You will need to develop a pattern of checking and double checking your alarm to make sure it is properly set to wake you up in the mornings. There is another issue with alarm clocks with making sure they are set properly and that is to ensure you have a backup battery in your alarm clock. A back up battery will give you about an hour of time to get the power back on in case of a power failure to keep your settings saved in the alarm clock. This is something that will happen from time to time that you will have no control over so in order to avoid the problem just make sure that a battery is present in the clock and that it is fully functional. http://hubpages.com/hub/what-causes-over-sleeping Problems Linked to Oversleeping Diabetes. In a study of almost 9,000 Americans, researchers found a relationship between sleep and the risk of diabetes. People who slept more than nine hours each night had a 50% greater risk of diabetes than people who slept seven hours per night. This increased risk was also seen in people who slept less than five hours per night. The researchers did not draw conclusions about the physiological link between long sleep and diabetes. But they did suggest that oversleeping could be indicative of underlying medical problems that increase the likelihood of diabetes. Obesity. Sleeping too much could make you weigh too much, as well. One recent study showed that people who slept for nine or 10 hours every night were 21% more likely to become obese over a six-year period than were people who slept between seven and eight hours. This association between sleep and obesity remained the same even when food intake and exercise were taken into account. Headaches. For some people prone to headaches, sleeping longer than usual on a weekend or vacation can cause head pain. Researchers believe this is due to the effect oversleeping has on certain neurotransmitters in the brain, including serotonin. People who sleep too much during the day and disrupt their nighttime sleep may also find themselves suffering from headaches in the morning. Back pain. There was a time when doctors told people suffering from back pain to head straight to bed. But those days are long gone. You do need to curtail your regular exercise program when you are experiencing back pain. But doctors now realize the health benefits of maintaining a certain level of activity. And they recommend against sleeping more than usual, when possible. Depression. Although insomnia is more commonly linked to depression than oversleeping, roughly 15% of people with depression sleep too much. This may in turn make their depression worse. Thats because regular sleep habits are important to the recovery process. Need another reason not to overdo the ZZZs when youre blue? In certain instances, sleep deprivation can be an effective treatment for depression. Heart disease. The Nurses Health Study involved nearly 72,000 women. A careful analysis of the data from that study showed that women who slept nine to 11 hours per night were 38% more likely to have coronary heart disease than women who slept eight hours. Researchers have not yet identified a reason for the connection between oversleeping and heart disease. Death. Multiple studies have found that people who sleep nine or more hours a night have significantly higher death rates than people sleeping seven to eight hours a night. No specific reason for this correlation has been determined. But researchers found that depression and low socioeconomic status are also associated with longer sleep. They speculate these factors could be related to the observed increase in mortality for people who sleep too much http://www.webmd.com/sleep-disorders/guide/physical-side-effects-oversleeping Heres How to Stop Oversleeping: Step 1: Decide to Wake Upà ¢Ã¢â ¬Ã ¦ Theres no easier way to say it Oversleeping is an escapeà mechanism. If you want to stop oversleeping, youd have to figure out why some part of you chooses to stay in bed. Confront it. Then decide to deal with it,à insteadà of running away from it by oversleeping. Step 2: Get Motivated to Stop Oversleeping Come up with at least one strong reason WHY you want to stop oversleeping. Be as specific as you can.à It might help to write it down and read it to yourself daily. Change your attitude toward sleep. If you love to sleep, you have to start thinking about sleep as something you must do in order to survive. Nothing more. Stop making excuses like I need more sleep than the average person. You should be convinced that you can sleep less and have more energy than you have now, which is most likely true. Step 3: Commit to a Steady Sleep Schedule Its best if you can go to sleep and wake up at the same times every day. At least do you best to wake up at the same time, no matter how long you had sleptà ¢Ã¢â ¬Ã ¦ Put the clock away from bed, set a wake up call, ask someone to throw you out of bed, whatever you need to do to make sure you wake up on time. Step 4: Improve your sleep There are many simple things you can do to get high quality sleep, which will allow you to getà more energy from less sleep. Step 5: Reduce sleep gradually If you sleep 10 hours every night, dont move to 7 hours all at once. Reduce 30-60 minutes every week or so. Dont beat yourself up when you fail, because it might only make things worse. Just learn from your mistakes and come up with a plan for the next day. Step 6: Raise your physical and mental energy Its good to stop oversleeping. Its better to be a highly energetic person.à Start working on changing your habits, lifestyle and mindset eat well, exercise, think more positively and so onà ¢Ã¢â ¬Ã ¦ http://a-sleep.com/1563/how-to-stop-oversleeping/

SUPERSTITIOUS :: essays research papers
SUPERSTITIOUS Human beings are superstitious especially among Chinese. If anyone who claims that he or she is not superstitious is either a liar or a fool. A lot of us believe in certain things that do not have logical explanations. This is especially true in this multi-racial country of ours. Each community has its own beliefs. It would be impossible to discuss all of the beliefs of Chinese; therefore I will just touch on some of them. I still remember a few years ago, some of my friends and I went to a holiday in Bukit Bendera. One of friend decided to take some snapshots. So we all were dressed up and ready to be ââ¬Ëshotââ¬â¢. We had our individual photographs taken first, and then we decided to have group photographs. But one of my friends gave us a warning that did not made up any group of three. He said that misfortune will befall one of the three if they have their photographs taken together! After listened that everyone avoided being in a group of three. Although I STUDY SKILLS IN ENGLISH SSE 131 never heard of such a thing before but after hearing it, I did not want to take the risk. Actually it spoiled the fun a bit. I felt it was difficult to believe, even photographs can be superstitious. Honestly speaking, I do not know how much truth there is in this illogical belief but I do not dare to test it. After reading this, will you still dare to have your photograph to be taken with two other people? The number three is also taboo among cigarette smokers. On occasions I have seen a group of people lighting up their cigarettes only to a maximum of two persons per lighted match. Actually the light is slowly extinguished after two persons and then person number three will use a new match. This I have to define as the belief that maybe some tragedy will strike the third person who receives a lighted match. Well, here is another belief not to be challenged. When you are having a baby, there are some beliefs especially for the Chinese pregnant ladies such as: Don't use glue when you are pregnant because it will cause a difficult birth. Another thing is if you strike an animal during pregnancy, the newborn child will look like that animal and behave like one.
Universalizability and Philippine Supreme Court Cases :: Criminal Justice
Universalizability and Philippine Supreme Court Cases ABSTRACT: The requirement that legal reasoning be universalizable is so unquestioned as a legal doctrine that it is practically axiomatic. Recently, two Philippine Supreme Court cases have been decided in a manner that apparently dispenses with this requirement. I discuss these two cases in the light of the requirement. I conclude that the requirement, rather than being diminished by the two cases, has actually maintained its axiomatic status on the basis that the reasoning in the two cases is deficient: the first either for inequality in treatment or for lack of clear guidance, and the second for the failure to appear impartial. The requirement that judicial reasoning be universalizable, that the justifying reasons for a decision are to be articulated or at least must be capable of being articulated in the form of a universal norm under which the facts of the case are to be subsumed so as to entail logically the decision, (1) is an acknowledged formal legal principle indispensable to any sound theory of adjudication. Recently, two Philippine Supreme Court Decisions, Alonzo v. IAC (2) and Marcos v. Manglapus, (3) challenged the very indispensability of such a requirement. This paper will discuss the interaction between and effects of these two decisions on the requirement of universalizability, by determining whether the requirement is indeed seriously challenged by the two cases and, conversely, by assessing and analyzing these two cases in terms of the requirement. These two decisions resolved the issues in the two cases by creating exceptions for the unique circumstances attendant to the cases, thus apparently dispensing with the requirement. In particular, the Alonzo case held: "In fact, and this should be clearly stressed, we ourselves are not abandoning the Cojenero and Buttle doctrines. What we are doing is adopting an exception to the general rule, in view of the particular circumstances of the case." (4) In the Marcos case, reference was made to the special circumstances involving President Marcos thus: "This case is unique. It should not create a precedent, for the case of a dictator forced out of office and into exile after causing twenty years of political, economic and social havoc in the country and within the short space of three years seeks to return, is in a class by itself." (5) In discussing the interaction between and effects of these two decisions on the requirement of universalizability, the paper will first briefly explain the rationale behind the requirement.

A Farewell To Arms by Ernest Hemingway Essay -- Farewell Arms Hemingwa
A Farewell to Arms is a novel by Ernest Hemingway about an American ambulance driver in Italy during World War I, and the nurse, Catherine Barkley, with whom he falls in love. The story is narrated by his driver, named Frederic Henry. Whether or not this book is truly an anti-war novel is debatable, but it well depicts the effects an ongoing war has on soldiers and how the men try to numb this pain. Henry's close friend at the front, Rinaldi, forgets the war with the help of sex and seduction, the priest takes comfort in God, the Captain has humor and jokes about the priest, and almost all drink profusely, taking wine and brandy like water. But the most important and notable attempt to escape from the pain of war is Henry and Catherine's: they hide from the real world in their imaginary tales of love, then become buried in obsession with each other, but, eventually, they truly love one another. Mr. Henry meets Ms. Barkley (very appropriately) in the springtime. Rinaldi originally was planning on having a relationship with the English nurse, but forfeited her to Henry when he saw their mutual interest. When Catherine and Henry first met, she was carrying a rattan stick, and Henry asks about it. Catherine explains: "ÃâIt belonged to a boy who was killed last year'... ÃâHe was a very nice boy. He was going to marry me and he was killed in the Somme.'" (Hemingway, 18) The fact that she is carrying around one of her fiancee's possessions shows that she is still mourning his death. Catherine, wanting escape from the grief of her fianceeÃâs death, and Henry, wanting to forget about the war, begin their relationship. Since their relationship was born of a need for entertainment rather than real mutual interest, it started off as... ...the end the world kills you. Catherine gets a hemorrhage, and Henry pleads with God not to let her die. Before she does, she tells Henry that she wants him to have other girls. Even while dying she was thinking about Henry's happiness, a sure sign of honest love. Catherine dies, and Henry walks to his hotel alone, in the rain. Henry and Catherine both tried to hide from the pain of reality in each other. Their relationship started as a meaningless game, but as their need for companionship grew they became obsessed with each other and their love. Finally, when the fantasies and dreams were not enough, they literally ran away from the war together. In the end, even though their love started as a lie, it is obvious that they both held a true love for each other. Works Cited Hemingway, Ernest. A Farewell to Arms .

A Dirty Job Chapter 5
5 DARKNESS GETS UPPITY Hey, Ray,â⬠Charlie said as he came down the steps into the storeroom. He always tried to make a lot of noise on the steps and usually fired a loud and early ââ¬Å"helloâ⬠to warn his employees that he was coming. He'd worked a number of jobs before coming back to take over the family business, and had learned from experience that nobody liked a sneaky boss. ââ¬Å"Hey, Charlie,â⬠Ray said. Ray was out front, sitting on a stool behind the counter. He was pushing forty, tall, balding, and moved through the world without ever turning his head. He couldn't. As a San Francisco policeman, he'd caught a gangbanger's bullet in the neck six years ago, and that was the last time he'd looked over his shoulder without using a mirror. Ray lived on a generous disability pension from the city and worked for Charlie in exchange for free rent on his fourth-floor apartment, thus keeping the transaction off both their books. He spun around on the stool to face Charlie. ââ¬Å"Hey ââ¬â uh ââ¬â I wanted to say that, you know, your situation, I mean, your loss. Everybody liked Rachel. You know, if I can do anything ââ¬â ââ¬Å" It was the first time Charlie had seen Ray since the funeral, so the awkwardness of secondary condolences had yet to be forded. ââ¬Å"You've done more than enough by picking up my shifts. Whatcha working on?â⬠Charlie was trying desperately to not look at the various objects in the shop that were glowing dull red. ââ¬Å"Oh, this.â⬠Ray rotated and pushed back so that Charlie could see the computer screen, where there were displayed rows of portraits of smiling, young Asian women. ââ¬Å"It's called Desperate Filipinas dot-com.â⬠ââ¬Å"Is this where you met Miss LoveYouLongTime?â⬠ââ¬Å"That was not her name. Did Lily tell you that? That kid has problems.â⬠ââ¬Å"Yeah, well, kids,â⬠Charlie said, suddenly noticing a matronly woman in tweed who was browsing the curio shelves at the front of the store. She was carrying a porcelain frog that was glowing dull red. Ray clicked on one of the pictures, which opened a profile. ââ¬Å"Look at this one, boss. It says she's into sculling.â⬠He spun on his stool again and bounced his eyebrows at Charlie. Charlie pulled his attention from the woman with the glowing frog and looked at the screen. ââ¬Å"That's rowing, Ray.â⬠ââ¬Å"No it's not. Look, it says she was a coxswain in college.â⬠Again with the eyebrow bounce, he offered a high five. ââ¬Å"Also rowing,â⬠Charlie said, leaving the ex-cop hanging. ââ¬Å"The person at the back of the boat who yells at the rowers is called the coxswain.â⬠ââ¬Å"Really?â⬠Ray said, disappointed. He'd been married three times, and been left by all three wives because of an inability to develop normal adult social skills. Ray reacted to the world as a cop, and while many women found that attractive initially, they expected him eventually to leave the attitude, along with his service weapon, in the coat closet when he arrived home. He didn't. When Ray had first come to work at Asher's Secondhand, it had taken two months for Charlie to get him to stop ordering customers to ââ¬Å"move along, there's nothing to see here.â⬠Ray spent a lot of time being disappointed in himself and humanity in general. ââ¬Å"But, dude, rowing!â⬠Charlie said, trying to make it all better. He liked the ex-cop in spite of his awkwardness. Ray was basically a good guy, kindhearted and loyal, hardworking and punctual, but most important, Ray was losing his hair faster than Charlie. Ray sighed. ââ¬Å"Maybe I should search for another Web site. What's a word that means that your standards are lower than the desperate?â⬠Charlie read down the page a little. ââ¬Å"This woman has a master's degree in English lit from Cambridge, Ray. And look at her. She's gorgeous. And nineteen. Why is she desperate?â⬠ââ¬Å"Hey, wait a minute. A master's degree at nineteen, this girl is too smart for me.â⬠ââ¬Å"No she's not. She's lying.â⬠Ray spun on the stool as if Charlie had poked him in the ear with a pencil. ââ¬Å"No!â⬠ââ¬Å"Ray, look at her. She looks like one of those Asian models for Sour Apple Flavored Calamari Treats.â⬠ââ¬Å"They have that?â⬠Charlie pointed to the left side of the front window. ââ¬Å"Ray, let me introduce you to Chinatown. Chinatown, this is Ray. Ray, Chinatown.â⬠Ray smiled, embarrassed. There was a store two blocks up that sold nothing but dried shark parts, the windows full of pictures of beautiful Chinese women holding shark spleens and eyeballs like they'd just received an Academy Award. ââ¬Å"Well, the last woman I met through here did have a few errors and omissions in her profile.â⬠ââ¬Å"Like?â⬠Charlie was watching the woman in tweed with the glowing frog, who was approaching the counter. ââ¬Å"Well, she said that she was twenty-three, five feet tall, a hundred five pounds, so I thought, ââ¬ËOkay, I can have fun with a petite woman.' Turns out it was a hundred and five kilos.â⬠ââ¬Å"So, not what you expected?â⬠Charlie said. He smiled at the approaching woman, feeling panic rise. She was going to buy the frog! ââ¬Å"Five foot ââ¬â two-thirty. She was built like a mailbox. I might have gotten past that, but she wasn't even twenty-three, she was sixty-three. One of her grandsons tried to sell her to me.â⬠ââ¬Å"Ma'am, I'm sorry, you can't buy that,â⬠Charlie said to the woman. ââ¬Å"You hear the expression all the time,â⬠Ray went on, ââ¬Å"but you hardly ever meet anyone really trying to sell his own grandmother.â⬠ââ¬Å"Why not?â⬠the woman asked. ââ¬Å"Fifty bucks,â⬠Ray said. ââ¬Å"That's outrageous,â⬠the woman said. ââ¬Å"It's marked ten.â⬠ââ¬Å"No, it's fifty for the grandmother Ray is dating,â⬠Charlie said. ââ¬Å"The frog is not for sale, ma'am, I'm sorry. It's defective.â⬠ââ¬Å"Then why do you have it on the shelf? Why is it marked for sale? I don't see any defect.â⬠Evidently she couldn't see that the goofy porcelain frog was not only glowing in her hands, it had started to pulsate. Charlie reached across the counter and snatched it away from her. ââ¬Å"It's radioactive, ma'am. I'm sorry. You can't buy it.â⬠ââ¬Å"I wasn't dating her,â⬠Ray said. ââ¬Å"I just flew to the Philippines to meet her.â⬠ââ¬Å"It is not radioactive,â⬠the woman said. ââ¬Å"You're just trying to jack up the price. Fine, I'll give you twenty for it.â⬠ââ¬Å"No, ma'am, public safety,â⬠Charlie said, trying to look concerned, holding the frog to his chest as if shielding her from its dangerous energy. ââ¬Å"And it's clearly ridiculous. You'll note that this frog is playing a banjo with only two strings. A travesty, really. Why don't you let my colleague show you something in a cymbal-playing monkey. Ray, could you show this young woman something in a monkey, please.â⬠Charlie hoped that the ââ¬Å"young womanâ⬠would win him points. The woman backed away from the counter, holding her purse before her like a shield. ââ¬Å"I'm not sure I want to buy anything from you wack jobs.â⬠ââ¬Å"Hey!â⬠Ray protested, as if to say that there was only one wack job on duty and he wasn't it. Then she did it, she quickstepped to a rack of shoes and picked up a pair of size-twelve, red Converse All Stars. They, too, were glowing. ââ¬Å"I want these.â⬠ââ¬Å"No.â⬠Charlie tossed the frog over his shoulder to Ray, who fumbled it and almost dropped it. ââ¬Å"Those aren't for sale either.â⬠The tweed woman backed away toward the door, holding the sneakers behind her. Charlie stalked her down the aisle, taking the occasional grab at the All Stars. ââ¬Å"Give them.â⬠When the woman butt-bumped into the front door and the bell over the jamb jingled, she looked up and Charlie made his move, faking hard left, then going right, reaching around her and grabbing the laces of the sneakers, as well as a scoop of big, tweedy ass in the bargain. He quickstepped back toward the counter, tossed the sneakers to Ray, and then turned and fell into a sumo stance to challenge the tweed woman. She was still at the door, looking as if she couldn't decide to be terrified or disgusted. ââ¬Å"You people need to be put away. I'm reporting you to the Better Business Bureau and the local merchants' association. And you, Mr. Asher, can tell Ms. Severo that I will be back.â⬠And with that, she was through the door and gone. Charlie turned to Ray. ââ¬Å"Ms. Severo? Lily? She was here to see Lily?â⬠ââ¬Å"Truant officer,â⬠Ray said. ââ¬Å"She's been in a couple of times.â⬠ââ¬Å"You might have said something.â⬠ââ¬Å"I didn't want to lose the sale.â⬠ââ¬Å"So, Lily ââ¬â ââ¬Å" ââ¬Å"Ducks out the back when she sees her coming. The woman also wanted to check with you that the notes for Lily's absences were legitimate. I vouched.â⬠ââ¬Å"Well, Lily is going back to school, and as of right now, I'm back to work.â⬠ââ¬Å"That's great. I took this call today ââ¬â an estate in Pacific Heights. Lots of nice women's clothes.â⬠Ray tapped a piece of notepaper on the counter. ââ¬Å"I'm not really qualified to handle it.â⬠ââ¬Å"I'll do it, but first we have a lot to catch up on. Flip the ââ¬ËClosed' sign and lock the front door, would you, Ray?â⬠Ray didn't move. ââ¬Å"Sure, but ââ¬â Charlie, are you sure that you're ready to go back to work?â⬠He nodded to the sneakers and frog on the counter. ââ¬Å"Oh, those, I think there's something wrong with them. You don't see anything unusual about those two items?â⬠Ray looked again. ââ¬Å"Nope.â⬠ââ¬Å"Or that once I took the frog away from her, she went right for a pair of sneakers that are clearly not her size?â⬠Ray weighed the truth against the sweet deal he had here, with an apartment and under-the-table income and a boss that had really been a decent guy before he went 51/50, and he said, ââ¬Å"Yeah, there was something strange about her.â⬠ââ¬Å"Aha!â⬠said Charlie. ââ¬Å"I just wish I knew where I could get a Geiger counter.â⬠ââ¬Å"I have a Geiger counter,â⬠Ray said. ââ¬Å"You do?â⬠ââ¬Å"Sure, you want me to get it?â⬠ââ¬Å"Maybe later,â⬠Charlie said. ââ¬Å"Just lock up, and help me gather up some of the merchandise.â⬠Over the next hour Ray watched as Charlie moved a set of what seemed randomly chosen items from the store to the back room, directing him to under no circumstances put them back out or sell them to anyone. Then he retrieved the Geiger counter that he'd obtained on a sweet trade for a stringless oversized tennis racket and tested each item as Charlie instructed. And, of course, they were as inert as dirt. ââ¬Å"And you don't see any glowing or pulsating or anything in this pile?â⬠Charlie asked. ââ¬Å"Sorry.â⬠Ray shook his head, feeling a little embarrassed that he was witnessing this. ââ¬Å"Good first day back to work, though,â⬠Ray said, trying to make it all better. ââ¬Å"Maybe you should call it a day, go check on the baby, and make that estate call in the morning. I'll box this stuff up and mark it so Lily won't sell or trade it.â⬠ââ¬Å"Okay,â⬠Charlie said. ââ¬Å"But don't throw it out, either. I'm going to figure this out.â⬠ââ¬Å"You betcha, boss. See you in the morning.â⬠ââ¬Å"Yeah, thanks, Ray. You can go home when you finish.â⬠Charlie went back to his apartment, checking his hands the whole way to see if any of the red glow from the pile of objects had rubbed off on them, but they seemed normal. He sent Jane home, fed and bathed Sophie, and read her to sleep with a few pages from Slaughterhouse-Five, then went to bed early and slept fitfully. He awoke the next morning in a haze, then sat bolt upright in bed, eyes wide and heart pounding when he saw the note sitting on the nightstand. Another one. Then he noticed that this time it wasn't his handwriting, and the number was obviously a phone number, and he sighed. It was the estate appointment that Ray had made for him. He'd put it on the nightstand so he wouldn't forget. Mr. Michael Mainheart, it read; then upscale women's clothing and furs, with a double underline. The phone number had a local exchange. He picked up the note, and under it was a second piece of notepaper, this one with the same name, written in his own handwriting, and under it, the numeral 5. He didn't remember writing any of it. At that moment, something large and dark passed by the second-story bedroom window, but by the time he looked up, it was gone. A blanket of fog lay over the Bay and from Pacific Heights the great orange towers of the Golden Gate Bridge jutted through the fog bank like carrots from the faces of sleeping conjoined twin snowmen. In the Heights, the morning sun had already opened the sky and workmen were scurrying about, tending yards and gardens around the mansions. When he arrived at the home of Michael Mainheart the first thing Charlie noticed was that no one noticed him. There were two guys working in the yard, to whom Charlie waved as he passed, but they did not wave back. Then the mailman, who was coming off the big porch, drove him off the walkway into the dewy grass without so much as an ââ¬Å"excuse me.â⬠ââ¬Å"Excuse me!â⬠Charlie said, sarcastically, but the mailman was wearing headphones and listening to something that was inspiring him to bob his head like a pigeon feeding on amphetamines, and he bopped on. Charlie was going to shout something devastatingly clever, then thought better of it, for although it had been some years since he'd heard of a postal employee perpetrating a massacre, as long as the term ââ¬Å"going postalâ⬠referred to anything besides choosing a shipping carrier, he felt he shouldn't press his luck. Called a wack job by a complete stranger one day and shouldered off the sidewalk by a civil servant the next: this city was becoming a jungle. Charlie rang the bell and waited to the side of the twelve-foot leaded-glass door. A minute later he heard light, shuffling steps approaching and a diminutive silhouette moved behind the glass. The door swung open slowly. ââ¬Å"Mr. Asher,â⬠said Michael Mainheart. ââ¬Å"Thank you for coming.â⬠The old man was swimming in a houndstooth suit that he must have bought thirty years ago when he was a more robust fellow. When he shook Charlie's hand his skin felt like an old wonton wrapper, cool and a little powdery. Charlie tried not to shudder as the old man led him into a grand marble rotunda, with leaded-glass windows running to a vaulted, forty-foot ceiling and a circular staircase that swept up to a landing that led off to the upper wings of the house. Charlie had often wondered what it was like to have a house with wings. How would you ever find your car keys? ââ¬Å"Come this way,â⬠Mainheart said. ââ¬Å"I'll show you where my wife kept her clothes.â⬠ââ¬Å"I'm sorry about your loss,â⬠Charlie said automatically. He'd been on scores of estate calls. You don't want to come off as some kind of vulture, his father used to say. Always compliment the merchandise; it might be a piece of crap to you, but they might have a lot of their soul poured into it. Compliment but never covet. You can make a profit and preserve everyone's dignity in the process. ââ¬Å"Holy shit,â⬠Charlie said as he followed the old man into a walk-in closet the size of his own apartment. ââ¬Å"I mean ââ¬â your wife had exquisite taste, Mr. Mainheart.â⬠There was row upon row of designer couture clothing, everything from evening gowns to racks, two tiers high, of knit suits, arranged by color and level of formality ââ¬â an opulent rainbow of silk and linen and wool. Cashmere sweaters, coats, capes, jackets, skirts, blouses, lingerie. The closet was shaped like a T, with a large vanity and mirror at the apex, and accessories on each wing (even the closet with wings!), shoes on one side, belts, scarves, and handbags on the other. A whole wing of shoes, Italian and French, handmade, from the skins of animals who had led happy, blemish-free lives. Full-length mirrors flanked the vanity at the end of the closet and Charlie caught the reflection of himself and Michael Mainheart in the mirror, he in his secondhand gray pinstripe and Mainheart in his ill-fitting houndstooth, studies in gray and black, stark and lifeless-looking in this vibrant garden. The old man went to the chair at the vanity and sat down with a creak and a wheeze. ââ¬Å"I expect it will take you some time to assess it,â⬠he said. Charlie stood in the middle of the closet and looked around for a second before replying. ââ¬Å"It depends, Mr. Mainheart, on what you want to part with.â⬠ââ¬Å"All of it. Every stitch. I can't stand the feel of her in here.â⬠His voice broke. ââ¬Å"I want it gone.â⬠He looked away from Charlie at the shoe wing, trying not to show that he was tearing up. ââ¬Å"I understand,â⬠Charlie said, not sure what to say. This collection was completely out of his league. ââ¬Å"No, you don't understand, young man. You couldn't understand. Emily was my life. I got up in the morning for her, I went to work for her, I built a business for her. I couldn't wait to get home at night to tell her about my day. I went to bed with her and I dreamed about her when I slept. She was my passion, my wife, my best friend, the love of my life. And one day, without warning, she was gone and my life is a void. You couldn't possibly understand.â⬠But Charlie did. ââ¬Å"Do you have any children, Mr. Mainheart?â⬠ââ¬Å"Two sons. They came back for the funeral, then they went home to their own families. They offer to do whatever they can, butâ⬠¦Ã¢â¬ ââ¬Å"They can't,â⬠Charlie finished for him. ââ¬Å"No one can.â⬠Now the old man looked up at him, his face as bereft and barren as a mummified basset hound. ââ¬Å"I just want to die.â⬠ââ¬Å"Don't say that,â⬠Charlie said, because that's what you say. ââ¬Å"That feeling will pass.â⬠Which he said because everyone had been saying it to him. As far as he knew, he was just slinging bullshit clichs. ââ¬Å"She was ââ¬â â⬠Mainheart's voice caught on the edge of a sob. A strong man, at once overcome by his grief and embarrassed that he was showing it. ââ¬Å"I know,â⬠Charlie said, thinking about how Rachel still occupied that place in his heart, and when he turned in the kitchen to say something to her, and she wasn't there, it took his breath. ââ¬Å"She was ââ¬â ââ¬Å" ââ¬Å"I know,â⬠Charlie interrupted, trying to give the old man a pass, because he knew what Mainheart was feeling. She was meaning and order and light, and now that she's gone, chaos falls like a dark leaden cloud. ââ¬Å"She was so phenomenally stupid.â⬠ââ¬Å"What?â⬠Charlie looked up so quickly he heard a vertebra pop in his neck. Hadn't seen that coming. ââ¬Å"The dumb broad ate silica gel,â⬠Mainheart said, irritated as well as agonized. ââ¬Å"What?â⬠Charlie was shaking his head, as if trying to rattle something loose. ââ¬Å"Silica gel.â⬠ââ¬Å"What?â⬠ââ¬Å"Silica gel! Silica gel! Silica gel, you idiot!â⬠Charlie felt as if he should shout the name of some arcane stuff back at him: Well, symethicone! Symethicone! Symethicone, you butt-nugget! Instead he said, ââ¬Å"The stuff fake breasts are made of? She ate that?â⬠The image of a well-dressed older woman macking on a goopish spoonful of artificial boob spooge was running across the lobes of his brain like a stuttering nightmare. Mainheart pushed himself to his feet on the vanity. ââ¬Å"No, the little packets of stuff they pack in with electronic equipment and cameras.â⬠ââ¬Å"The ââ¬ËDo Not Eat' stuff?â⬠ââ¬Å"Exactly.â⬠ââ¬Å"But it says right on the packet ââ¬â she ate that?â⬠ââ¬Å"Yes. The furrier put packets of it in with her furs when he installed that cabinet.â⬠Mainheart pointed. Charlie turned, and behind the large closet door where they had entered was a lighted glass cabinet ââ¬â inside hung a dozen or so fur coats. The cabinet probably had its own air-conditioning unit to control the humidity, but that wasn't what Charlie was noticing. Even under the recessed fluorescent light inside the cabinet, one of the coats was clearly glowing red and pulsating. He turned back to Mainheart slowly, trying not to overreact, not sure, in fact, what would constitute an overreaction in this case, so he tried to sound calm, but not willing to take any shit. ââ¬Å"Mr. Mainheart, I appreciate your loss, but is there something more going on here than you've told me?â⬠ââ¬Å"I'm sorry, I don't understand what you mean.â⬠ââ¬Å"I mean,â⬠Charlie said, ââ¬Å"why, of all the used-clothing dealers in the Bay Area, did you decide to call me? There are people who are much more qualified to deal with a collection of this size and quality.â⬠Charlie stormed over to the fur cabinet and pulled open the door. It made a floof-tha sound that the seal on a refrigerator door makes when opened. He grabbed the glowing jacket ââ¬â fox fur, it appeared to be. ââ¬Å"Or was it this? Did the call have something to do with this?â⬠Charlie brandished the jacket like he was holding a murder weapon before the accused. In short, he thought about adding, are you fucking with me? ââ¬Å"You were the first used-clothing dealer in the phone book.â⬠Charlie let the jacket drop. ââ¬Å"Asher's Secondhand?â⬠ââ¬Å"Starts with an A,â⬠Mainheart said, slowly, carefully ââ¬â obviously resisting the urge to call Charlie an idiot again. ââ¬Å"So it has nothing to do with this jacket?â⬠ââ¬Å"Well, it has something to do with that jacket. I'd like you to take it away with all the rest of it.â⬠ââ¬Å"Oh,â⬠Charlie said, trying to recover. ââ¬Å"Mr. Mainheart, I appreciate the call, and this is certainly a beautiful collection, amazing, really, but I'm not equipped to take on this kind of inventory. And I'll be honest with you, even though my father would be spinning in his grave for telling you this, there is probably a million dollars' worth of clothes in this closet. Maybe more. And given the time and space to resell it, it's probably worth a quarter of that. I just don't have that kind of money.â⬠ââ¬Å"We can work something out,â⬠Mainheart said. ââ¬Å"Just to get it out of the house ââ¬â ââ¬Å" ââ¬Å"I could take some of it on consignment, I suppose ââ¬â ââ¬Å" ââ¬Å"Five hundred dollars.â⬠ââ¬Å"What?â⬠ââ¬Å"Give me five hundred dollars and get it out of here by tomorrow and it's yours.â⬠Charlie started to object, but he could feel what felt like the ghost of his father rising up to bonk him on the head with a spittoon if he didn't stop himself. We provide a valuable service, son. We are like an orphanage to art and artifact, because we are willing to handle the unwanted, we give them value. ââ¬Å"I couldn't do that, Mr. Mainheart, I feel as if I'd be taking advantage of your grief.â⬠Oh for Christ's sake, you fucking loser, you are no son of mine. I have no son. Was that the ghost of Charlie's father, rattling chains in his head? Why, then, did it have the voice and vocabulary of Lily? Can a conscience be greedy? ââ¬Å"You would be doing me a favor, Mr. Asher. A huge favor. If you don't take it, my next call is to the Goodwill. I promised Emily that if something ever happened to her that I wouldn't just give her things away. Please.â⬠And there was so much pain in the old man's voice that Charlie had to look away. Charlie felt for the old man because he did understand. He couldn't do anything to help, couldn't say, It will get better, like everyone kept saying to him. It wasn't getting better. Different, but not better. And this fellow had fifty more years in which to pack his hopes, or in his case, his history. ââ¬Å"Let me think about it. Check into storage. If I can handle it, I'll call you tomorrow, would that be all right?â⬠ââ¬Å"I'd be grateful,â⬠Mainheart said. Then, for no reason that he could think of, Charlie said, ââ¬Å"May I take this jacket with me? As an example of the quality of the collection, in case I have to divide it among other dealers.â⬠ââ¬Å"That would be fine. Let me show you out.â⬠As they passed into the rotunda, a shadow passed across the leaded-glass windows, three stories up. A large shadow. Charlie paused on the steps and waited for the old man to react, but he just tottered on down the staircase, leaning heavily on the railing as he went. When Mainheart reached the door he turned to Charlie, extending his hand. ââ¬Å"I'm sorry about that, uh, outburst upstairs. I haven't been myself since ââ¬â ââ¬Å" As the old man began to open the door a figure dropped outside, casting the silhouette of a bird as tall as a man through the glass. ââ¬Å"No!â⬠Charlie dove forward, knocking the old man aside and slamming the door on the great bird's head, the heavy black beak stabbing through and snapping like hedge clippers, rattling an umbrella stand and scattering its contents across the marble floor. Charlie's face was only inches from the bird's eye, and he shoved the door with his shoulder, trying to keep the beak from snapping off one of his hands. The bird's claws raked against the glass, cracking one of the thick beveled panels as the animal thrashed to free itself. Charlie threw his hip against the doorjamb then slid down it, dropped the fox jacket, and snatched one of the umbrellas from the floor. He stabbed up into the bird's neck feathers, but lost his purchase on the doorjamb ââ¬â one of the black talons snaked through the opening and raked across his forearm, cutting through his jacket, his shirtsleeve, and into the flesh. Charlie shoved the umbrella with all he had, driving the bird's head back through the opening. The raven let out a screech and took flight, its wings making a great whooshing noise as it went. Charlie lay on his back, out of breath, staring at the leaded-glass panels, as if any moment the shadow of the giant raven would come back, then he looked to Michael Mainheart, who lay crumpled on his side like a stringless marionette. Beside his head lay a cane with an ivory handle that had been carved into the shape of a polar bear that had fallen from the umbrella stand. The cane was glowing red. The old man was not breathing. ââ¬Å"Well that's fucked up,â⬠Charlie said.

The Air Pollution Report
Air pollution is a major problem facing our environment today. This dilemma is harmful to every single living creature on this planet. How can we limit the causes of air pollution? There are industrial as well as residential causes of air pollution. How can we limit the effects of air pollution? We all know it affects the environment, but do we all know it also can affect us directly? How can we control air pollution? Is the government doing its job to protect us? Air pollution can be defined as impureness of the air. Air pollution is all around us. It might not be as clearly visible in some areas as others but the fact is that air pollution is still there affecting us in some way, shape, or form. It has been known to cause illness and/or death. Many people are not aware of this. There are two main causes of air pollution. One of the main causes is natural pollution. ââ¬Å"Natural pollution is windblown dust, pollen, fog, etc. â⬠The other main cause is people pollution. ââ¬Å"People pollution is the chief concern and most serious form. Most of people pollution is caused by industry, cars, trucks, and airplanes. â⬠The causes of air pollution go on and on. There are residential causes and industrial causes. Residential causes are those such as automobile emissions and forest fires. Industrial causes are those such as factory emissions and the burning of fossil fuels. One residential cause is the emissions of automobiles. This is probably the most harmful cause, at least in the United States of America it is. People drive automobiles every day to get from point A to point B. If automobiles did not exist, the air would most likely be cleaner but we would not be able to travel long distances in short periods. In any case, the problem remains that automobile emissions are harmful to the environment. This is how they generate automobile emissions into the atmosphere. Motor vehicle emissions are generated in several different ways and locations during engine/vehicle operation. The most important sources are, of course, those produced in combustion and vented through the exhaust pipe. These exhaust gases consist mainly of unburned HCs, CO, and NOx and account for approximately 90- 92% of all vehicle emissions. Some products of combustion are not vented through the exhaust system, as they slip by the piston rings and the cylinder walls. These ââ¬Å"blowbyâ⬠gases consist mainly of unburned HCs that accumulate in the crankcase exhaust port. A third source of emissions is the votalization of HCs through the carburetor and fuel tank vents. Carburetor emissions are pronounced during the ââ¬Å"hot soakâ⬠period immediately following vehicle operation. Forest fires caused by the carelessness of humans puts harmful smoke into the environment. These forest fires do not happen often, but when they do, there is mass destruction caused to the atmosphere. In the early 1950's, forest fires in the Southeastern United States covered huge areas of the country with smoke so thick that flights were canceled in New York City. Chlorofluorocarbons or CFC's were developed by chemists at General Motors in 1928. When they were developed, they were looked upon as ââ¬Å"miracleâ⬠gases that could be safely used for many purposes. They were not toxic. They were not carcinogens. They did not corrode the materials with which they came in contact. Nor were they flammable. Finally they could be manufactured easily and inexpensively. Over the years these CFC's have been made to serve many purposes from refrigerator coolants to jet streams in aerosol cans and polystyrene material to air conditioners. When people do not properly dispose of CFC's, they could escape into the atmosphere, creating a hole in the ozone layer. Air pollution was first realized as a major problem during the Industrial Revolution in Europe. Industrial pollution is particles (especially of metal dusts) and waste gases (especially carbon monoxide, sulfur oxides, and nitrogen oxides) that are waste products of industry and end up in the air. Industrial emissions are the second largest pollutants of the atmosphere after automotive exhausts. â⬠Industries that are the major pollutants include petroleum refining, metal smelting, iron and steal mills, grain mills, and the flour handling industry. The most common chemical natured factory pollutant is methylene chloride. The burning of fossil fuels is a major cause of air pollution. Fossil fuels are formed from the remains of ancient plant and animal life such as coal and natural gas. If complete combustion of fossil fuels was possible, it would only produce heat energy, water vapor, and carbon dioxide. However, since this not possible because the level of oxygen is never ideal, carbon monoxide forms. The incombustible material enters the atmosphere as smoke, dust, soot, and particles of tarry (tar-like) hydrocarbon substances. Small amounts of mineral and metal impurities are released into the air as fly ash. Sulfurous impurities produce sulfur oxides, especially sulfur dioxide. Sulfur dioxide combines with water in the air to form sulfuric acid, the largest component of acid rain. â⬠Air pollution, as like any other pollution, is harmful to the environment. Unlike other pollutions though, air pollution is not always visible in the environment. Air pollution is the cause of acid rain, smog, and the hole in the ozone layer. Acid rain damages living organisms and materials. Deposition from acids, such as sulfuric acid and nitric acid and mixes with the rain and goes into the soil and bodies of water. This is most common in the Northeastern United States, where fossil fuel burning is highly concentrated. ââ¬Å"Acid rain is killing more than lakes. It can scar the leaves of hardwood forests, wither ferns and lichens, accelerate the death of coniferous needles, sterilize seeds, and weaken the forests to disease, infestation, and decay. Below the surface, the acid neutralizes chemicals for plant growth, strips others from the soil and carries them to the lakes and literally retards the respiration of the soil. â⬠From this you can see that biological damage is most pronounced in forests and lakes. In bodies of water, acid shock, caused by runoff of highly acidic water into lakes and streams when snow melts can greatly affect fish and other aquatic life. It also affects farmers. Vegetation may show damage through bleaching and spotting on leaves. In urban areas acid rain discolors and speeds up the erosion of marble, cement, historic monuments, and statues. When exposed to acid rain, steel corrodes two to four times faster in urban and industrial areas than in rural areas. Soot and grit deposited by acid rain onto buildings, cars, and clothes results in these materials needing to be cleaned and restored. In the United States alone, acid rain causes billions of dollars damage to materials. Smog is dirty fog. ââ¬Å"Smog is a sort of ââ¬Ëatmospheric soup' of pollutants cooked up by the action of sunlight. This thick, brown haze is made of air polluted by automobile exhaust fumes, smoke, and aerosols. â⬠Smog contains chlorinated and organic phosphates that get unleashed into the air from blowing farm particles, heavy metals, and evaporating acid. These chemicals make the smog even more toxic than most people think. Smog is developed when weather conditions are in the mid- eighties and there is little wind. Therefore, smog does not affect all parts of the world. It is most common in a city such as Los Angeles where these weather conditions exist. Ozone depletion is looked upon as a problem that up till now, we can not fix. Air pollution has caused this hole in the ozone layer. The ozone layer absorbs 99% of the sun's harmful energy. It prevents ultraviolet radiation from reaching the Earth's surface and the troposphere. It protects humans from sunburn, skin and eye cancer, and cataracts. It also prevents much of the oxygen in the troposphere from being converted to ozone (gas). In the mid-seventies chemists F. Sherwood Rowland and Mario J. Malian discovered ââ¬Å"CFC's were creating a global chemical time bomb by lowering the average concentration of ozone in the stratosphere. â⬠In other words, the CFC's were and are creating a hole in the ozone layer. As long as we keep using these CFC's the hole is going to continue to grow wider and wider. Effects on the Health of Living Organisms Air pollution is hazardous to our health. It can endanger the health of living organisms in several ways. One way, is by introducing particulate matter and poisonous gases into the respiratory systems of humans, animals, and plant leaves. Another way is by increasing the acidity of precipitation, which alters the chemistry of soil and water. One more way, is that it engages chemical reactions in the atmosphere that increase the exposure of living organisms to harmful radiation. Yet another way that it affects living organisms is by altering globally, the composition and ultimately the temperature of the atmosphere and thus producing conditions that threaten the survival of living organisms. In humans air pollution especially affects our respiratory system. Our respiratory system has a number of protective mechanisms built to protect against exposure to air pollution. Hairs in the nose filter out large particles. The mucus lining in the upper respiratory tract helps capture and dissolve smaller particles and gaseous pollutants. Sneezing and coughing helps to remove contaminated air and mucus when the respiratory system is exposed to pollutants. Long term exposure to cigarette smoke and other air pollutants can ruin the natural defenses, resulting in respiratory conditions such as allergic reactions like asthma, and diseases such as lung cancer, emphysema, or chronic bronchitis. Air pollution can also cause other health problems. It can cause extreme allergic reactions. It also can cause headaches, nausea, rashes, and swelling. Such activities as jogging, bicycling, and other strenuous outdoor activities, while being done in areas with high concentrations of air pollution, can cause vigorous coughing and chest pain. The hole in the ozone layer is the cause of many cases of skin cancer. There are three basic approaches to control air pollution. The first approach is called preventive measures. This means that they would change the raw materials sed in industry or the ingredients of fuel. The second approach is called dispersal measures. That is raising of the smokestacks. The third one is called collection measures. This is done by designing equipment to trap pollutants before they get into the atmosphere. Most highly industrialized countries have legislation to prevent and/or control air pollution. In the U. S. air pollution is the responsibility of the state and local governments. All states have an air quality management program that are patterned after federal laws. The basic federal law is the Clean Air Act of 1970. It was last amended in 1990. Under law the Federal Environmental Protection Agency sets the standards for air quality. The EPA sets the limits on the amounts of air pollutants that can be given off by automobiles, factories, and other sources. Air quality programs have improved many areas. There are several examples on how these air quality programs have improved areas. One example is that burning low sulfur coal and oil in factories and power plants has lowered levels of air pollution in the areas of the factories and plants. Another example is that automobile engines have been redesigned to emit lower emissions. New cars are equipped with devices such as catalytic converters which change pollutants into harmless substances. Because of this, air pollution from car exhaust has also been reduced. The EPA released the Pollution Prevention Strategy in February of 1991. The strategy provides guidance on the EPA's ongoing environmental protection efforts and includes a plan for achieving substantial voluntary reductions of targeted high risk industrial chemicals. The major component of the strategy is the Industrial Toxics Project. The EPA has identified seventeen high risk industrial chemicals that offer significant opportunities for prevention. These seventeen pollutants present both significant risks to human health and the environment and opportunities to reduce such risks through prevention. ââ¬Å"Scrubbers are pollution control devices used in industry to remove aerosols and waste gases. â⬠Wet scrubbers operate by directing sprays of water or other liquids into chambers containing exhaust gases. The gases are then washed away in the liquid. Another form of scrubber works by a process called adsorption in which gases are removed by activated charcoal and filtering. Another way to control air pollution is to use alternate or renewable sources of energy. One of these alternate sources is solar power. The number of solar power plants is increasing as the markets expand for this power source. There is absolutely no pollution from solar power. ââ¬Å"However, backup systems using conventional fuels are needed at night, during bad weather, and in the snowbelt areas, where the sun is often obscured during the winter months. Another thing is that the cost of solar energy is much higher than fossil fuels. Another alternate form of energy is nuclear power. Nuclear power is energy that is generated by radioactive fuels at nuclear plants. Nuclear power is often described as clean power when it is compare to fossil fuels. Nuclear power would limit air pollution problems since nuclear plants do not produce carbon dioxide or any of the gases that cause acid rain. On the downside, if there are nuclear power plants, there is always the threat of a nuclear fallout. If any radioactive materials escape from the plant, they could expose the people to radioactive contamination. The dilemma of air pollution is a major problem that faces our world today. What if we can't go outside because the smog is to thick? What happens when the acid rain gets potent enough to eat right through our skin? What do we do when the hole in the ozone layer widens and melts the polar ice caps? These could be some of the questions we will ask if we don't find ways to control the problem of air pollution.
