 　　Some people think killing¹ animals for food is cruel and unnecessary and some people think it is essential for daily diet.

　　To what extent do you think about these two views?

　　Before we examine the issue of whether killing animals for food is cruel and unnecessary or essential for our daily diet, I think that first we need to classify the term “animals” into two categories – wild animals and domestic animals.

　　In terms of wild animals, they make up an essential part of nature. Wildlife is also important in scientific research. With that view in mind, I cannot but think that killing animals for food is not only cruel and unnecessary, but also damages ecosystem². The use of animals for food simply deprives them of their right to survival. Moreover, we do not need to eat them for survival. Yet, the activities of human beings and human population growth have increased the danger for wildlife. If this continues to happen, human beings will lose much of great value that cannot be replaced.

　　On the other hand, the rapid growth of the world’s population and the rise in the standards of living have created further demands for food.

　　Thus, I think that it is necessary for people to rear domesticated³ animals and kill them as a source of food. Furthermore, livestock⁴ has other benefits, such as providing such food products as butter, cheese, eggs, and milk in addition to meat and valuable by-products as fur, hair, leather, and wool.

　　In conclusion, we human beings have great obligations for wild animals, as they are a chain in the ecosystem that needs to be protected, while tamed animals could serve human needs for food.
