I saw people vacationing in nature a number of us went leaving debris on the grass. I caught up and stopped them. -Wait, what are you doing, why do you throw trash? It is possible to make!-What's the matter, boy?Just if you don't leave the trash there you may be able to save the environment!-How?-If you don't leave trash, nature will not be contaminated and the air will be clean for you!Take care of nature and it will do you good. Said the boy.
