It is a natural process for animal species to become extinct. There is no reason why people should try to prevent this from happening. Do you agree or disagree?Ar

In the history of the earth, there have been many extinctions of animals. Based on

this

fact, many people argue that

this

is a natural phenomenon and humanity should not be concerned about it.

Although

indeed,

this

is a typical feature of nature, I do not agree that the international community should let everything go too far.

According to

many scientists, especially evolution theorists, in the history of the earth, there have been six remarkable

extinction

periods. The majority of them originated from natural phenomena,

For instance

, about 260 million years ago, dinosaurs and other enormous reptiles got extinct because of the clash between the earth and an asteroid. It has become the most well-known

extinction

period among scientists and the public. Another noticeable example is the Ordovician Mass

Extinction

, which happened about 200 years before the disappearance of dinosaurs. Many biologists indicate that

For instance

, thylacine, or Tasmanian tiger, was one of the main species in Australia until there were many campaigns killing them in the late 19th century and early 20th century, and it was declared extinct in 1936. One of the prey of
