A clean world shouldn't have violence. That is what I think a clean world should be. To tell you the truth I think a clean earth is many thins put together. Right now I will tell you some of the specifics. In our world I'd like no violence.
Violence is probably one of the main roots to why our world is getting worse.
Fighting, meanness, and bad words are included. Then I'd like no littering because years from now our world could become a giant litter ball. Just picking up a little bit of trash helps. There is so much more, but these two explain a clean earth. A clean world would be better place to live.
