To keep the environment clean and safe, people should stop smoking, and polluting the air. What I mean is that people should stop smoking and polluting the air, they should stop using fuel based cars and use solar powered cars. This would stop a lot of pollution in this world. Do you think people should stop smoking? Well first it would keep your heath clean; second it would make so much difference in the earth by blowing out second hand smoke. Also I think humans should come up with a new technology to stop these big factories from blowing out dirty black smoke, that would really make a difference in the earth.
