There are many animals that have become extinct due to humans, such as the dodo, which died out within two hundred years of being discovered by humans. There is also the Eurasian mink, which was hunted frantically by humans and became extinct in 1997.

There are many species in the world that have become extinct, and there are two main reasons for the extinction of these extinct species, one is natural and the other is man-made. Some species cannot adapt to the rapid changes in the current environment and still do not change their habits, so they will naturally be eliminated by nature.

can disrupt the food chain, such as the following story:
A long time ago, people wanted to have more deer, but it was found that there were never more deer anyway. It was discovered that because wolves always ate deer, people began a 10-year process of killing wolves. After 10 years, the wolves were finally killed.
People couldn't help but cheer. But then it turned out that there were fewer deer. And the grass in the grassland is sparse.
It turned out that since the wolves were hunted, the deer had no natural predators, so the number grew unlimitedly. As a result, the grass in the vicinity was almost eaten up, so some of the deer migrated to other places, and some of them starved to death. The reason is that people kill all the wolves, which leads to the destruction of the food chain.
So don't hunt animals excessively, no matter what they are!

Summary. Hello dear, how many animals are killed by humans every year, and how many species go extinct? According to statistics, at least 50,000 species of organisms in the world become extinct every year In China, about 200 species have become extinct; About 5,000 species of plants have been endangered in recent years, and about 398 species of vertebrates are also endangered Species extinction is a natural process, but the current human activities have greatly accelerated the rate of species extinction The pollution and destruction of the natural environment by the over-growing population is increasing day by day, and the amount of material and energy that humans demand from the environment has exceeded the capacity that nature can provide

The number of parent animals killed is incalculable, and there are direct and indirect effects, and there is no way to count them.
