text: To kick this off, limiting the usage of cars would reduce the amout of air pollution that we are surrounded in now. Think about it millions of cars on and running everyday, sometimes if you look closely thers black gas coming out of the exhaust pipe.. And you're breating that? Out of millions of cars where do you think all those fumes go? they don't just dissapear! We're breating it! sure you might say "So if im breathing it doesn't that mean i should be dead?!" no.. that's not the case.. Yes it's bad for you but it hurts the earth mostly the gases break apart the atmosphere we have around to block other fumes from other places out. Think of the earth as a hamster in a ball.. The hamster is the earth and the ball is out atmosphere. The holes in the ball are the holes made from the gases that are released from our cars. This could let any type if gas in. In places like China there's a huge problem caused by all the cars.. it's called smog. Think of fog all over the place but its black and smells really bad. Not only that but it's really bad for you. You may think why don't we have that here? Well China is the most populated country in the world and almost everyone has a car. China is a pretty busy place you'd imagine because of all the people. Well you're right.. All the fumes coming out of those cars cause all that smog to contaminate everything there. Like water, animals, food, and even you! It's very bad. China needs to limit the usage of their cars in order to stop problems like that because it can effect everything around them. We should start worrying about the smog aswell because America is a pretty big place and all the busy cars can cause something similar to a smog, it may not be as big bu it will still cause damage. With all this said hopefully you understand what air pollution does and how we can reduce it.
