Save our nature! I still remember when I was a little boy, there were not many tall buildings. We can see the trees everywhere, in the countryside, we can play with the lovely animals , and feel the fresh air,what a wonderful memory!But now, the beautiful scene disappeared, our sight was blocked out by the skyscrper everywhere. The air is polluted and the water is dirty , so what has happened to our nature?Some people may say,'we are the masters of nature. But is it true ? Nowadays we have face more and more problems because of human's behavior. The temperature is higher year by year, more and more ground is turning to desert, and the water from our city's river can not be drunk. If we still make no sense to save our nature ,maybe one day in the future, we will have no fresh air to breathe and no clean water to drink...So, from now on ,from you and me ,from the little things in our life ,learn to save our nature, to protect our enviornment,and to stop people damaging our nature ! Everybody , let's do it !
