Nowadays, experimental usage of animal hasbecome a widely concerned issue around the world. People hold diverse views towards it.
Adversaries claim that it is an extremely crude behavior. Animals, especially mammals, like dogs, cats, rabbits, rats, which are the major victims in the experimentation, are usually human’spets. Pet owners are strongly against it for they firmly believe that animals suffer physically and mentally as we do. When equality is advocated in the modern world, it is inhuman to disrespect creatures that are not human beings.
Furthermore, a number of experts pointed out that it would be at high stake of depending on the results of animal experiment; since they differ from us in many ways. Take the body structure for example, we can’t imagine humans try to jump from the height of nine stories without any protection because cats survive out of the same test.
Those in favor of the idea about usage of animal declare that using animal is an advisable choice. On one hand because their bodies are similar in function to ours. For instance, they catch colds, suffer from stomachs and heart diseases, which more importantly influenced by diet and habits. The consequences of the test may not be applied to humans, although they are highly connected to the human situations. On the other hand, those creatures yell and act abnormally when they feel uncomfortable, which is what exactly researchers expect. In addition, there is an easy-to-answer question: isn’t it crueler to test directly on people with little knowledge on the objects’ effects? In a word, there is nothing better than animal that resemble human the best for experiment.
Personally, I am not a supporter of animal experiments, yet there is anything more suitable can replace them, I accept using animals for tests, but take good care of them when they are not in the laboratory.

In the past, there have been many endangered animals. Now they are extinct. Does it matter? Has our environment been affected by their absence? Has the quality of our own life been changed? The answer to these questions is “Yes.”
Yes. It does matter if we destroy an endangered species habitat to develop more farmland, housing or industrial parks. There is a delicate balance of nature. If one small part is removed, it will effect all the other parts.For example, if certain trees are cut down, bats will have no place to roost. If they cannot roost, they cannot breed. If there are no bats, there will be no animal, or bird to eat certain insects that plague our crops.
Yes. 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 were destroyed. Now these flowers are disappearing from certain areas. We will no longer be able to enjoy their beauty.
Yes. The quality of our life has been changed America used to be covered with giant 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 alternatives for our farmlands, housing, and industries. We have alternatives; the animals do not.

Many animals are in danger of dying out.
As is shown in the chart, we can see the number of animal species decreases faster and faster and this trend will continue.
From 1980 to 20xx, at least 1 million animal species have disappeared. Worse still, more and more wild animals are in great danger.
It is not a piece of sensational news; it is a fact, a harsh reality. Unfortunately, we may not see these animals in the near future.
