Some people think that animals should be treated as friends. Yet others only consider animals as sources of food and clothing. What is your opinion?

Sample Answer

There is a growing tendency nowadays for some people to treat animals as living meat and walking fur. This leads to the cruel slaughter of animals all over the world every year. Yet, in my opinion, instead of killing animals, human beings should treat them as their friends.

It is an undeniable fact that animals play a vital role in maintaining the subtle balance of the earth's ecological system. The lack of this essential part will bring about the destruction of the whole world. Therefore, to some extent, killing animals is equal to digging our own graves.

For thousands of years, many animals have given loyal service to humans. Pigeons convey messages in wartime, and dogs help to detect crime. Even pigs, which many people think are the most stupid animals, are used in the battle against drugs. There is no doubt that our lives would be far less convenient without a little help from our animal friends.

Animals also help humans in a spiritual way. There is nothing better than keeping a cat or a dog if you want your kids to be more independent and responsible. It is also noted that senior citizens live longer if they keep pets after their retirement.

To sum up, animals are human beings' friends. Those who regard animals as merely a source of food and clothing should at least bear one thing in mind: Being kind to animals is being kind to ourselves. Therefore, for our own future benefit, please treat animals with love and care.
