Unfortunately, people often litter.But we should not forget that saving nature we do worse than myself.We must keep order.If everyone takes a small step for purity, would be a lot better.Before you throw a piece of paper by urns, think! You make bad only yourself! Man and nature should not compete who's who! Without each other we are, not what counts! Against nature can't go! She no options wins. But only hold a grudge. And she сиах revenge oneself.
