Some animal species such as dinosaurs and dodos become extinct because of natural procees.So, it is not neceary to try and prevent this from happening.Do you agree or disagree?
In the contemporary world, with the development of society and economy, there are decreasingly animal species.According to this phenomenon, some people hold the point that public sparing no efforts to prevent animals is significant as well as fundamental.However, at the same time, an argument that the mysterious extinction of such species as huge dinosaurs and flightle dodo birds that had been wiped out due to natural procees rather than human behaviors is put forward.In their opinion, species extinction is nothing to do with human.
As for me, I agree with the former point of view.First and foremost, as far as I am concerned, even though it is inevitable that creatures die out, a series of harmful human activities to endangered animals are evitable.In the recent decades, it is common that hunting thousands of wild animals, such as elephants, lions, and south china tiger, just to name a few.As we all know, it is damage to diversity of species.It is generally acknowledged that biodiversity is eential to existence of living things.As an old saying goes,” species diversity is to our life, what water is to fish”.There is no doubt that for the sake of protecting species, government laying down laws to ban overhunting is vital as well as neceary.What is more, from the point of my view, establishing nature reserve is a wise and wisdom approach to protect animals.
Neverthele, we have to admit that plenty of species extinction remains the greatest mystery.For instance, no one knows exactly the reason why dinosaurs became extinct millions years ago.In addition, it is believed by a huge number of scientists that about 99.9% of animal species might have ceased to exist（不复存在）as a result of natural procees, which implies that human beings did not get involved in the animal species extinction.
To sum up, even if the natural procees are not avoidable, taking a wide range of related and efficient measures to slow down the speed of species extinction is of value as well as foundation.
