From the picture, it is not difficult for us to find a man holding a gun to shoot the prey opposite him, but he does not know that the prey is behind his own life, since humans have become the rulers of the earth, human beings have gradually forgotten that they are also a member of the biosphere. According to statistics, the number of animals hunted each year, China, the official data is about 40,000 per year, about 100,000 in Europe and the United States, and in Africa, millions of animals are hunted, many animals are endangered, perhaps, in a few years, we can only see those creatures that are still active on the earth from the illustrated book. Of course, for the hunters, they only pay attention to money and profit, after all, there are too many rich and unkind beings on the earth we live in, and their claims are that I have money, and I have to eat rare, and those who are artificially bred are low-level food, and I don't eat it, and once I eat it, it will be rare.

They don't know that nature also has a temper, and more and more serious environmental problems have been enveloping the earth, and the food you eat may be buried in the chain of revenge in nature, and the more you move towards greed, the more you enter this cycle, just like the man with a gun in the picture, when the last card falls, what else accompanies him, only a cold shotgun.

At the beginning of the 20th century, there were about 4,000 wild deer in the Kaibab Forest in the Rocky Mountains of the western United States, and they were accompanied by packs of wolves, threatening the survival of the deer. For the sake of the tranquility of these deer, in 1906, the United States decided to carry out a wolf eradication operation, and by 1930 more than 6,000 wolves had been shot. The wolf is nowhere to be seen in the Kaiba Burlin district.

So the deer began to give birth there without any worries and "unplanned", and soon the number of deer grew to more than 100,000. Thriving deer eat all edible plants, eat up weeds, destroy forests, and reduce the number of other animals that feed on plants, leaving the herd suffering from hunger and disease. By 1942, the number of deer in the Kaibab Forest had dropped to 8,000, and the majority of them were sick and weak, and the once-thriving deer family was in sharp decline.

This backfires because the wolf has been exterminated. On the one hand, wolves prey on some deer, so that the total number of deer is controlled, so that they do not reproduce to the extent that they degrade vegetation; On the other hand, most of the deer preyed on by wolves are old, weak, sick and disabled, which helps the survival of the fittest and the succession of deer herds. On the other hand, the deer is often in a state of escape under the chase of wolves, which promotes the robust development of the deer. Since the wolf disappeared, the deer had no natural predators, the "lazy man" was weak, and the deer herd degenerated.

In order to save the evil consequences of wolf extermination, the United States formulated a plan to "lure wolves into the house" in the 70s of the last century. However, this plan was opposed by some people and was not implemented in time. With the increase in people's awareness of the environment, the "Bringing Wolves into the House" program was finally implemented in 1995.

The first wild wolves were released from Canada into the Rocky Mountains, and the forest was full of life.

In fact, the main thing is that human beings keep killing and finally perish themselves.
