We need animals．Every animal has its place in the balance(平衡) of nature．We should try to help save the animals．

Some people think zoos are good places．The zoos give the animals the comfortable and safe living places．If the animals get hurt or ill, people will take care of them．The zoo is a good place to know the rules in the wild world．We can be much closer to nature．We can know more about the animals in the zoos by watching, listening even smelling instead of just looking at the pictures in books．

Some people don’t think animals feel happy in the zoos．Animals like pandas, wolves and bears usually live in the wild．They play and find food by themselves．They are free and happy in the wild．If they are in the zoos, food is enough and rooms are comfortable．They do not need to do their best to find food to eat or places to stay in．They just walk around, sleep day and night, but they are not free at all．

I think we should build national parks as wild life nature reserves to protect animals．If we do nothing, animals will get fewer and fewer．
