The Earth is a beautiful place, I mean it's where we live, But have you ever wondered what our inventions do to the atmosphere? Some things like cars can do a lot of damage to the atmosphere, cars can make the atmosphere get pollution, which is not good, why don't we just walk to where we need to go or ride our bike, we get healthier and also polution isn't really good for us either, it can cause lung problems. There are also other things that can cause pollution for instance factories,gases, and etc. That's just my opinion to what I think is causing problems to earth.
