glabal warming law


Now a day, the global warming is starting to be most popular news in the media. No matter in newspaper of the TV news every week sure they will have some news is about the global warming. The temperature rises and the sun’s heat and light is trapped in the earth’s atmosphere. And affecting many parts of the world and It might take a few year to destroy the whole creatures in the earth. But even how serious the media describe how serious the causes of global warming bring to the human. Human will still do whatever they like. Same in our country as while, people tend to be a ethical of selfish and just take care they own feeling and without concern other people feeling. All this cause our earth involve in the trouble. So in order to teach people and let them understand the serious cause of global warming. I think we need the government to set the law to help them understand that the serious of global warming.Like other country government they made a law called The Clean Air Act so there is less air pollution. Global warming is making people get very bad illnesses that could make them disabled, very sick, and sometimes even die. The Clean Air Act is making many companies change their products to decrease these problems. Part of the law says that you may not put a certain amount of pollutants in the air. Hairspray and some other products, like foam cups, had this problem. Making and using these products let out too many volatile organic compounds (VOC’s), ozone-destroying chemicals (chlorofluorocarbons (CFC’s), and related chemicals (such as CO2) into the air. Now, almost all of these products have a label on them telling people what this product can do to the environment and many people. The Clean Air Act has also made car companies change some of the things inside of the cars. Cars pollute a lot. While cars make more than half of the world’s smog (visible pollution in the air), many things that cars need to move and heat up make even more pollution. Some things that are inside of cars, buses, trucks, and motorcycles, like gasoline, pollute the air when the fuel is burned. It comes out as a chemical and when mixed in the air, forms smog. Smog is a kind of pollution that you see in the form of a cloud. If you have ever been to California you can see a lot of smog in some places. Sometimes the smog gets so bad that you cannot see at all! Smog forms when car exhaust, pollution from homes, and pollution from factories mixes in the air and has a chemical reaction. The sun’s heat and light add to the reaction.
Cars, buses, and trucks are also responsible for over 50% of dangerous chemicals let into the air. Some of these chemicals can cause cancer, birth defects, trouble breathing, brain and nerve damage, lung injures, and burning eyes. Some of the pollutants are so harmful that they can even cause death.
