2019/11/30雅思写作范文：In modern world, it is no longer necessary to use animals for foods or use animal products, for instance, clothing and medicines. To what extent do you agree or disagree?现代社会，不再需要动物作为食物或其它一些产品，例如衣服和药品。你同意吗?
The advancement science and technology provides people with alternative options that can replace animals as food or other products. Even, there is voice advocating the abundance of animal food and products. However, in my opinion, this is actually unfeasible.
Admittedly, the use of animals in certain areas can be replaced by other materials. Animals’ smooth and soft fur is traded to make clothes for the rich. To wear fur coats has long been regarded as fashionable and stylish, but recently, environmentalists condemn it as cruel and ruthless to animals. Luckily, manufactories today are able to produce artificial fur coats with similar quality. In addition, animals are widely used in medicine, especially traditional Chinese medicines. The development of chemistry makes it possible to analyze what elements are effective in curing diseases and then to find alternatives in other sources. In both these two domains, the consumption of animals becomes unnecessary.
However, animals are important and indispensable source of food. To eat meat is a habit that human beings have nurtured for thousands of years. From meat of animals, people absorb valuable nutrients, such as protein and vitamins. Annually, we consume increasing amount of pork, beef, chicken, eggs, milk, etc. At present, there is no other alternative source of food that can substitute meat. Moreover, animal meat also plays an essential role in food culture. Almost in every country, people have their own special way of cooking and preference on tastes of meat, like pork shank in Germany and fried fish in Britain. The exemption of meat in dietary will surely arouse fierce objection and complaints.
In a nutshell, the utilization of animals is unnecessary in clothing industry and certain medicine, but we still depend on animals for food.
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(替代品)for them. While I certainly agree that now we do not have to kill wild animals for the purpose of our survival(生存), I think we need food from domestic animals for our health.
On the one hand, we should protect wild animals, especially the endangered(濒临灭绝的)species of animals and recognise 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(禁止). Hunting rare animals will lead to their extinction(灭绝)and affect the animal diversity(多样性), which is detrimental to (对......有害的)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(以......为代价)their extinction.
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(移除)meat from our table. The same is true to clothing. The hide(兽皮)of animals like cow and sheep can strengthen the durability of the clothes.
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(很需要)animal products for our own benefits.
