It is a natural process for animal species to become extinct. There is no reason why people should try to prevent this from happening.

Some people believe that we should not try to prevent animal species from becoming extinct because extinction is a natural process. I largely disagree with this view. Although some species 1vanish organicallynaturally disappear because they fail to adapt to environmental changes, humans should still protect endangered animals, particularly when their decline is caused by human activities.

It is true that extinction is sometimes 2an inherent evolutionary phenomenonpart of the natural process. Throughout history, some animal species have disappeared because they could not adapt to changes in climate, 3food supplies, or habitat conditionsfood supply or living conditions. For example, many species that lived millions of years ago eventually became extinct when their environment 4underwent catastrophic shiftschanged dramatically. In such cases, it may be unrealistic for humans to prevent every species from disappearing. Nature is constantly changing, and the survival of a species depends partly on its ability to adapt to these changes. Therefore, 5humans need not intervene inpeople do not need to interfere with every case of natural extinction.

However, many endangered species today are threatened not only by natural changes but also by human activities. Deforestation, pollution, 6overhuntingexcessive hunting and urban development can destroy 7animal habitatsanimals' habitats and rapidly reduce their populations. 8In these situations, humans clearly have a responsibility to protect endangered species because we are partly responsible for their decline. For example, conservation programmes have helped increase the population of giant pandas after their numbers 9plummetedfell significantly in the past. Protecting endangered animals can also maintain biodiversity and contribute to the stability of ecosystems. If 10a keystone speciesan important species disappears, other animals and plants within the same ecosystem may also be affected. Therefore, protecting endangered species 11yields mutual benefits for ecological integrity and human welfarecan benefit both nature and human society.

In conclusion, although extinction can sometimes occur naturally, I disagree that there is no reason for humans to prevent it. We may not be able to 12preventstop every natural extinction, but we should protect species whose survival is seriously threatened by human activities.
