Not agree to use animals as food and in other products like clothing and medicines From my personal perspective, I don’t think it essential to kill living creatures to meet human’s surviving demanding, as human society has been modernizing and there are other substitutes. The following article will exhibit my detailed discussion. Granted, people contingent a lot on animals, because they provide us not only the food but also raw materials for producing clothes and medicines. It is no exaggeration to say that human civilization was promoted after the ancient people learnt how to hunt and cook. However, it is intensely impersonal to take away creatures’ lives in order to satisfy ourselves, for the reason that they have feelings just like human beings, and their right of survival should be respected too. A lot of researches have already shown that animals possess particular feelings such as happiness and sadness, and they are able to feel pains as us do. Therefore, they deserve an appropriated treatment, preventing their rights for survival from being deprived. What’s more, since scientists have proved that vegetarians lead to a healthy life as well as average people who consume both meat and vegetables, the necessity of eating meat for balanced nutrition virtually decreases. In addition, with the development of material technology, clothes made from fiber materials are as warm as those made from animals’ skins, making killing animals for their skins become unreasonable and even illegal. To sum up, with the appearance of substitutes of animals products, killing creatures to meet human demanding is no longer reasonable and impersonal. Therefore, I back up the idea that it is not necessary to product food, clothing and medicines at the costs of animals’ lives.
