Environment Protection
安吉高级中学 姚瑶
Good afternoon, ladies and gentlemen! It is really my great pleasure to stand here and share with you something about our environment.
Do you know the story The Last Leaf by O. Henry? “When the last leaf falls, I will go and my life will have to end.” This is what Johnsy said when she was in despair, she feared that she would “turn loose hold on everything and go sailing down, down, just like one of those poor leaves. ”

Serious problem, isn’t it?
But fortunately, more and more attention is paid to this matter and actions are taken. Tree-cutting is restricted and even forbidden in many places and young trees are being planted. Activists are yelling for attention and today’s contest itself is just part of this. Not too long ago, I read such an interesting event: in a small city in Indernesia, one must plant 2 trees when he or she is getting married and 5 when getting divorced and anot
