Our planet Earth is only a tiny part of the universe, but nowadays it's the only place where we can live. But now our planet is in danger. And we have to think what we can do to solve this problem. We can plant trees and create parks for animals. We mustn’t drop litter in the street. We must recycle our wastes; we should stop polluting activities, because chemicals is destroying our planet. We must do something to save our planet!
