Before this, we had better keep them protected, particular to some rare species. Someone said safeguard of wild animals is a waste of resource, but I do not agree. It seems that we would spend some time, wealth and manpower on this meaningless thing. Actually we also do this for human being ourselves. Wild animals have no place in the 21st contrary, and the protection for them is a waste of resource. To what extent, do you agree or disagree with the above statement? With the rapid progress of society, people’s living standard is dramatically improved, with more convenience and resource ing to us. However, our living environment at the same time is getting more polluted. One effect of this phenomenon is that there is not enough space for wild animals to survive, and many people hold an opinion that it would be a waste of resource to protect wild animals. Nevertheless, I think exactly the opposite way. The environment is a prehensively biological life cycle, with human beings, animals and plants playing affecting each other accordingly. Wild animals occupy an essential position in the life cycle. Let’s look at a very simple example. Although snakes are very dangerous and frightening, they can catch mice, and mice can destroy the crop as well as sanitary surroundings. Here it is easy to understand that if there are not enough snakes, the number of mice would grow rapidly, doing more harm to us. Then , should not we protect the snake? Actually, we are saving resource by doing this because trying to save something that is already destroyed seriously costs more. Secondly, in present, quite a number of problems such as desertification and rivers dried up, caused by excessive exploitation of natural resource, have arisen an increasing number of people aware of environment protection. More and more places, I think, should be planned for wild animals in 21st contrary. Thus, it is obviously noticed that more trees are planted and more wildlife conservation areas are planned, ensuring that wild animals will be under protection. As we can see from the improvement, in the 21st contrary, wild animals would be leading a happy life. To sum up, we cannot live without wild animals due to their profound effects on us. For this reason, we should try our best to protect them. Let’s remember one thing—protecting wild animals is equivalent to protecting ourselves. Wild animals have no place in the 21st contrary, and the protection for them is a waste of resource. To what extent, do you agree or disagree with the above statement? Biological diversity has never been as threatened as it is today as a result of the process of human civilization. The various forms of pressure created by human activity have destroyed natural balance, led to the deterioration of natural habitats, geic erosion and the rarity, even disappearance, of a number of plant and animal species. As the pace of civilization accelerates, more people, taking more space, needing to use more natural resources, engaging in evergrowing consumption, impose sever deterioration on the habitat of animals. An increasing number of people e to realize that the disappearance of animals will result in serious threat to the equilibrium of ecosystem. Simply put, the extinction of hawks, rateating bird seen in many regions, will result in the rapid propagation of rats. And rats, further, will destroy the prairies and threaten the other animals like gazelles, zebras, and others, who live on grass and green lands. The coexistence of animals and human beings creates perfect harmony and brings about vividness to our pla. It is hard to imagine what our world would be like without animals. Sociologists also point our that the disappearance of animals can cause social and economic problems. Animals trade, as a supporting sector to the world economy, was very active before. However, the situation is beyond control since animals trade is very profitable and alluring. Many species cannot escape the adversity of being killed. Certainly, our diet cannot be without meat. There are living stocks, which can provide us with sufficient and nutritious produce. Therefore, we need not to resort to wild animals, especially the endangered ones. To protect animals is to protect our living environment. Every individual should join efforts to keep the diversity of animals. 措施類解決方案： The gap of living in
