One Saturday afternoon, Li Hua and Wang Ping, members from “Green Eyes”, was having an environmental protection activity near the riverside when they catch sight of a bird on the ground． They picked it out and found it wounded． Thinking it might die without timely help, they took it to home． They made a nest for it but fed it with rice and water． Under their treatment and care, the lucky birds got recovered soon． When time came for them fly the bird back to nature, they felt a bit pity but very delighting．
I think it’s worthwhile for him to do such a thing． Here I call on the public to show respect to nature． Only by changing the way we treat the environment can we get along good with it．
