Most of our enviornmental problems revolve around something we use everyday which is the car. Problems such as air pollution, car accidents, and lazyness. These things just don't effect you, if effects everyone including the envornment. This is something we should look out for ecause it is a very negative thing we have. Mainly air pollution because that affects everything.. And i mean everthing... Food, water, animals, plants, and even you.. So we all should look out for this and be a bt more responsible. We need more laws to help reduce the amount of smog and greenhouse gases that we have here today in our world. Hopefully you read this and learned alot about the importance of limiting the usage of cars and how it can effect everything.    Overly usage of cars not only has drastically harmed the environment but humans as well. This is why many countries have now leaned towards limiting the usage of cars. It might seem absurd especially if you heavily depend on your car to get to places, but the truth is cars harm. They're killing our world and therefore they're killing us.
