How powerful is human body?

At the end

There have been five major extinction on the planet, and each extinction will extinct more than 80%of species, but some scientists believe that the sixth great extinction is happening.

In the past 200 million years, 90 types of vertebrates will be extinct every 100 years, and higher animals will be extinct every 27 years. However, since the human industry revolution, the extinction speed of birds and mammals has increased by 100 to 1,000 times compared with the natural state, which will extinct species or even more than dozens of species every year.

For 400 years from 1600 to the present, as many as 724 high -level animals that are extinct because of human activities. Most of us are only impressed by the famous extinction species, but there are still many animals that have been extinct before humans know.

Some scientists even estimate that as of the 20th century, as many as 2 million animals have been extinct because of human activities. Some researchers are estimated based on the species area curve, the data obtained is even more amazing, as many as 140,000 animals are extinct each year.

In the process of natural evolution, humans have become powerful species, but the stronger the ability, the greater the responsibility. Only by protecting nature and continuous development can the wild resources of nature become our continuous wealth.
