Pollution in California

In California its becoming more and more polluted. Oil leaks happen a lot whenever there is an earthquake or just reasons made because of humans. We drive millions of cars in California and they cause the air to be more polluted. It makes the atmosphere weaker a lets more sunlight and warmth towards the earth. Whenever an earthquake occurs they cause everything to collapse and making dust that can harm the environment because of all of the chemicals mixed. This also causes oil leaks like i mentioned before. They cause the ground to become more polluted the air more polluted and to me it seems like maybe 90% of people that live here don't try to help with what is happening.
