1、    Nowadays problems with earth are getting more and more serious．For example，pollution is making the environment not anymore suitable for US to live in．Also，energy is running out．However，there is still something everyone can do in our daily lives to help save our planet．

First of all．we should turn off the lights when leaving a room．It’s really easy to do．Also，we’re supposed to turn off the showers while washing our hair．And are you still using paper napkins? You’d better stop now because paper is made from wood．If everyone uses paper napkins．a lot of trees will have to be cut down everyday．Maybe it is hard to stop using paper napkins，but we must try．At the same time，we should think of good ways to recycle paper．Another thing is that we must try to make our own bags when shopping instead of using plastic bags that are provided by the supermarkets．Finally，we must stop riding cars because ears pollute the air．For one thing, it’s good for our health．For another, it’s much cleaner．
