Section 2: Animal - Zoo

1. To what extent is the use of animals in scientific research acceptable? Should we use animals in scientific experiments? Animal 2.doc
- Most scientific research has to rely on the results of animal experiments. Other alternatives, such as computer modeling, that could replace animals are very limited. Some people think that using animals in scientific experiments is immoral and cruel.
- In my point of view, only animals can fulfill the requirements of scientific experiments in a real world. For example, some medical universities use dogs as a substitute to allow students to be trained in their surgical techniques. Most people understand that we cannot use humans in experiments because it may be harmful and dangerous for humans. In other laboratory experiments, scientist often use animals like rats, frogs and rabbits to observe the results because only these animals have a similar organs as humans. Therefore, we can not deny that animals contribute a lot to the development of science.
- Although it seems impossible to replace animals in scientific experiments, we should not give up on these matter. Furthermore, we should try our best to reduce the use of animals in scientific experiments. In addition, we should try to reduce pain and distress of the animals during the experiments. For example, we can anaesthetize them before doing any experiments.
- To summarize, we should put more effort into finding the better alternatives than using animals in experiments. In the mean time, we could improve our abilities to reduce the suffering of the animals in the experiments.
2. Many people have a close relationship with their pets. These people treat their birds, cats, or other animals as members of their family. In your opinion, are such relationships good? Why or why not? Use specific reasons and examples to support your answer.152 –unneccesary.
3. Some people think that human needs for farmland, housing, and industry are more important than saving land for endangered animals. Do you agree or disagree with this point of view? Why or why not? Use specific reasons and examples to support your answer. TOEFL45
Disagree:
- there is a delicate balance of nature. Of one small part is removed, it will effect all the other parts.
- Our environment has been affected by the absence of certain animals. Certain flowers are pollinated by butterflies which migrate from CAnada to Mexico. Some of the breeding grounds of these butterflies was destroyed. Now these flowers are disappearing from certain areas. We will no longer be able to enjoy their beauty.
- The quality has been changed. America used to be covered with giants trees. Now we have to visit them in one small park. Rain forests around the world are being cut down to make room for humans. We will never be able to see or study this fragile ecosystem.
- I would encourage us humans to look for other altanatives for our farmlands, housing and industries. We have alternatives, the animals do not.

Zoos are common places for people around the world. Animals are kept in zoos for several positive reasons: entertainment, education and conservation. On the other hand, zoos also cause some problems for animals, such as restrictions in their freedom or the destruction of the “wild” character of animals. This essay will discuss advantages and disadvantages about keeping animals in zoos.
Firstly, zoos are entertaining and interesting places for children. Virtually all children like to see animals in zoos. These are good places for families to relax. Zoos are not only interesting places for children, but they also give a chance for people who live in big cities get close to nature.
The next point is the scientists can research animals’ lives when they are kept in zoos easier than they are still living in forests. Scientists can study animals’ relationships, their life cycle, or their habits. In addition, researchers can learn how animals take care of each other such as how mothers look after their offspring. Moreover, researchers have acknowledged the importance of how to breed animals, which can reduce animal extinction.
Furthermore, endangered animals such as tigers, lions can be kept in captivity. Some animals that risk extinction might still exist because they are kept in safe from hunting.
However, zoos are not suitable for animals because they are kept in the limited area, in limited food for a long time. They may lose their freedom and their socialization with other animals. Besides, some animals have lost their “wild” character. For example, tigers might lose their hunting skills; platypuses might die because they are not used to live in limited areas.
Also, zoos cost a lot of money for land, animals’ food and labours. This may charge expensive entrance fees for people who want to go into zoos.
In summary, zoos are interesting places to people of all ages and zoos are also safe places for some species of animals. Yet, zoos’ owners should look after all animals and give them enough food and suitable captivity, as this will give being better advantages for animals’ lives.
