Air Pollution
Bill Gray

Air pollution comes from many different sources. Pollution comes from cars, acid rain, smog, and indoor pollution. It causes many problems for the environment including ozone depletion and global warming. We must soon realize what we are doing to the world we live in and the effects it could have in the future. We are living in a world that we control how it either continues to live or gradually dies. We can all do things to help our planet do what it has to do to stay alive. If we continue to pollute our planet we will no longer have this thing we call earth.

One of the biggest reasons for bad air quality is something we use everyday. Using public transportation instead of driving, for instance, reduces pollution by limiting the number of pollution-emitting automobiles on the road. During periods of particularly intense smog, pollution control authorities often urge people to avoid trips by car. By cutting down on the use of cars we will eventually eliminate car pollution by a huge margin. Just by using public transportation, we take about 20 cars off the road. But if a car is a must then just pack a few more bodies into it, which will keep one car on the road but that is better than four.

Acid Rain has many effects on the world. Acid rain forms when oxides of sulfur and nitrogen combine with atmospheric moisture to produce sulfuric and nitric acids. This can be carried over great distances from the winds and then deposited by rain. These airborn acids are harmful for the lungs and attack anything made of limestone, marble, or metal. They corrode statues and buildings, damage crops and forests, and make lakes and streams unlivable for fish or wildlife. By cuttting down on the emission of big industrial plants acid rain would not be as effective. Cutting down emission of large smoke stacks would also clear our air and help us to breath better.

Another form of air pollution is smog. Smog is a mixture of solid and liquid fog and smoke particles formed when humidity is high and the air so calm that smoke and fumes accumulate near their source. Smog can reduce natural visability and irritates the eyes and respiatory tract. Smog happens mostly over large cities that have huge industrial smoke stacks. Smog can have a huge effect on plants and animals also, plants gets less sun light and animals experience the same as humans do.

Indoor air pollutates are often unrecognized. Indoor pollutants include tobacco smoke, radon, and chemicals from synthetic carpets and furniture, pesticides, and household cleaners. One of the most recognized indoor pollutants is asbestos. We often experience these everyday and don't even realize it. Indoor pollutants can cause lung infection and can also invite infection, as you breath these pollutants in everyday it tends to have a long term effect on the well-being of your life.

There are two main effects of pollution on the world. One of these is Ozone depletion, which is when pollutants rise to the atmosphere and destroy the ozone layer. Many things hurt the ozone:  aerosol cans, air pollution, fluorine, nuclear weapons, and refrigeration. Many of these things contain chlorofluorocarbons (CFC's) which rise into the ozone and break  down chlorine atoms into ordinary oxygen atoms. This allows too many UV rays to enter, causing skin cancer, more cateracts, and a depletion of crops.

Another is Global warming, in which gases admit the suns light but reflect back downward  the heat that is radiated from the ground below, trapping heat in the earths atmosphere. The increase in these gases will make the earth a warmer place. The effects of a warmer world is expected to have more extreme weather. This is good for places expecting rainfall, but not for people who need the rain. This could also melt icecaps in the oceans and flood small islands.

There are many ways in which we can help clean up the air. We can start using public transportion, stop using things that contain CFC's and give a helping hand in trash pick-up when needed. We people need to start building things with less pollutants in them. By talking with your local environmental agencies you can get more involved and also keep up tp date on the most hazardous materials produced on Earth. Hopefully, in the future we will recognize what we are doing to the earth and start to stop it and help it get better.

Introduction

Don't subordinate your intro paragraph to its associated ideas. That means don't map out what you're going to tell me in your body paragraphs. Focus here on the background causes for air pollution. How long has it been with us, and how long have we known we should do something about it? Strengthen your thesis. You never want to have a negative thesis, but always a positive one. That means, try to make some point you can prove, that your body paragraphs can advance--not one that cannot be proven.

Body_1

Take some time to prove this to me. By how much, exactly, would we eliminate car pollution by cutting down on car use? What's the research on that? Why are there particular days when the use of cars is more dangerous than on other days? How realistic is car-pooling in a society that loves its cars and goes thousands of different directions every day?

Body_2

Give me a transition from the idea of car pollution to the idea of acid rain. Are cars significant contributors to acid rain? In what sense? What's in these airborne acids to make them so corrosive? How long does it take them to actually start showing results on people's property? In conclusion, how is this idea of acid rain important to the thesis?

Body_3

What conditions are necessary to produce smog? In what way does it differ from automobile emission pollution? Is it only an industrial phenomenon? Or can small towns inherit smog from big cities? Clarify that last sentence--how so? How does this idea of smog help to support and advance your thesis?

Body_4

Develop this idea on indoor pollutants--how prevalent is asbestos, anyway? Avoid second person. Your concluding sentence should show how this idea is important to the thesis. Strengthen the entire paragraph.

Body_5

This idea of ozone depletion and oxygen breakdown should be stressed through each of the previous body paragraphs. It's not really an independent and separate idea. Focus here, perhaps, on another type of pollutant in order to keep all your ideas in each of these paragraphs parallel.

Body_6

Ditto. This paragraph begins with an extended fragment. Clarify that. Focus here on another pollutant. Integrate the idea of global warming throughout the other body paragraphs. Develop the idea of melting icecaps and flooding small islands in your concluding paragraph on impact of the issue to society.

Conclusion

Develop along the lines of the impact this idea has on the thesis. Don't talk necessarily about what we should do about it, but how the problem has a large enough impact to generate community awareness. Close the paper by telling me why the thesis is important.
