atmosphere has many things to do.. it protects us in so many ways such us giving us people a fresh air every day. gives us atmospheric pressure.
Human activities impact/effect our air quality. For example, we drive gasoline cars. When the gas exhaust comes out out the car, it goes into the atmosphere; the gas has ozone and maybe methane. It also has carbon. If we get too much of these chemicals into our thin atmosphere, it harms the earth first of all with global warming, and, it harms us because we have to breathe in those poisonous gases everyday. One more example is when people smoke. The smoke not only damages the smoker's lungs, but the smoke that comes out lets other people breathe it in, and we do not want poisonous air inside of us.
