The period from 19s century to 20s century led to a huge advance in personal empowerment. This in turn set off an explosion in human demand for land. People always confront the dilemma of choosing whether more land should be used to satisfy the demand of human or protect the endangered animals. This problem is a prevalent topic undergoing serious debate in that it affects everybody in his or her daily work. Personally, I think more land should to protect the endangered animals. The reasons are as follows.
　　Firstly, the main reason for my propensity for protect the endangered animals is that more species of animals can help us balance our global environment. Any kind of animal in the world is played an important role in our environment. If one kinds of animal is distinguished, a serious of related animals will be endangered. This could break the biosphere. In short, protecting the endangered animals is protecting our environment.
　　Secondly, protect the endangered animals could make people’s life more colorful. For example many endangered animal is very cute good to our human such as panda and crane. Living with this animals in the earth make me feel happy. Can you imagine that what our life would be like if there is only human on this planet with no animals?
　　In conclusion, only with animals in the world can our human live happily.
　　In addition, too much land used to satisfy the demand of human will led to a sever consequence. For instance, my home town build a lot of building on the land where used to be many trees. This reduces the amount of trees, and the atmosphere in our city is getting worse. So more land used to satisfy human demand will turn out harm us.
　　It is undeniable that more land satisfies human demand has its own merits. The most extreme manifestation of the merits is the fact that it will solve the increasing demand of living place of human. Even though, however, we have no commplete evidence to suggest that more land to satisfy the demand of human is better than to protect the endangered animals.
　　From what has been discussed above, we may safely draw the conclusion that more land should be used to protect the endangered animals. Only when we protect the endangered animals can we led to wonderful life.
