On Saturday afternoon, Li Hua and Wang Ping, members of “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. Think it might die without timely help, they took it to home. They made a nest for it but fed it on rice and water. The lucky bird recovered soon. When it was time for the bird to fly away, they felt pity but were very delightful. I think it’s worthwhile for him to do such a thing. Here I call on the public to show respects for nature. Only by changing the way which we treat the environment can we get along well with it.
