On the one hand, we should protect wild animals, especially the endangered species of animals and recognize their importance to the entire eco-system. Some people hunt after endangered animals just to make beautiful clothes. This kind of behavior should be prohibited. Hunting rare animals will lead to their extinction and affect the animal diversity, which is detrimental to the balance between nature and animal. Therefore, wild animals ought to be protected, and we can’t satisfy our own pleasure at the price of their extinction. 

一方面，我们应该保护野生动物——尤其是濒危物种，也应该承认它们对整体生态系统的重要性。有些人仅仅是为了制作美丽的衣服就猎杀濒危动物，这种行为应当被禁止。猎杀珍稀动物将会导致其灭绝，影响生物多样性，这对动物和自然界之间的平衡十分有害。因此，野生动物应该受到保护，我们不能为了满足自己的利益而以他们的灭绝为代价。

But we still need some domestic animals such as chickens and ducks to supply our daily diet and nutrition. As we all know, meat provides a variety of nutrition that is difficult to obtain from vegetables and fruit. Some microelements in the meat can help prevent diseases too. For the sake of human beings’ health, we need to balance our diet so that it contains both meat and vegetables. It seems that it’s impossible to completely remove meat from our table. The same is true to clothing. The hide of animals like cow and sheep can strengthen the durability of the clothes. 

但我们仍旧需要一些家禽，例如鸡鸭等，来提供我们日常饮食所需要的营养。正如我们都知道，肉类能提供各类难以在蔬菜和水果中获取的营养。有些肉类中的微量元素还能预防疾病。为了人类的健康，我们需要平衡饮食结构，既要有肉类也要有蔬菜。我们似乎无法完全将肉类从餐桌上移除。而衣服也是一样。诸如牛皮和羊皮的动物皮毛能增强衣服的耐久性。

To sum up, while modern technology has made it quite necessary for us to kill wild animals to keep us from hunger and cold, we are still in great need of animal products for our own benefits. 

总的来说，尽管现代科技使我们没有必要通过杀害野生动物来远离饥饿和寒冷，但为了自身的利益，我们仍十分需要动物产品。

Nowadays, some people think it unnecessary for us to use animals for food, clothing, or medicines any longer because modern technology has found the substitutes for them. While I certainly agree that now we do not have to kill wild animals for the purpose of our survival, I think we need food from domestic animals for our health.
