Pollution is a big concern. Every family has one vehicle or more, or if they don't own one, there are families with more than one car that make up for them. This is an enormous pollution problem that happens throughout our country.
Exhaust fills the air and creates smog.
In some areas, smog is a problem that needs to be addressed right away. It affects so many other living creatures as well as plant life. We are the only ones who make this type of pollution. Another type of pollution is oil. People drain oil from their vehicles into the storm drains thinking that they are getting rid of it.
