keeping the environment clean

what can i do to keep the environment clean? people don't take care of the place here we live. we should start doing something about it because not taking care of can really hurt us. Now the question what can we do about it? well a group of us can go out to parks and clean out what people have done and it won't be so bad. but what can we also do for others won't do it is we can protest and show them how much damage littering is and how will we be if we don't stop it. so hopefully it will aware the people and we will ive in a cleaner place :)
