　　Den scientists at Aarhus University in Denmark recently discovered that North and South America has a richer and more diverse mammalian diversity without the destruction of the environment by human survival. They pointed out that the reason why there are so many species in Africa is not only due to the suitable climate, but also mainly because humans are less involved in this area. Human beings are "evil and efficient" predators. This breaks the laws of survival in the animal kingdom. Human activities have the greatest impact on the survival of species. Scientists say that the latest research results will provide an important foundation for the restoration and protection of nature. Scientists from Aarhus University in Denmark show that Africa’s rich and diverse mammalian species reflects that human activities are the main factor affecting the living environment of animals.

　　Canadian researchers call humans "evil and effective" super predators, which is why humans have extinct many species. Comparing other predators from the chart shows that this species is severely affected by human activities. Scientists from Aarhus University in Denmark show that Africa’s rich and diverse mammalian species reflects that human activities are the main factor affecting the living environment of animals. Based on the individual ecology of the species and the template of the current natural environment, the research team evaluated various natural distributions and reached relevant conclusions. ``In addition to Northern Europe, there are still many regions where mammal species have declined sharply. This is a global phenomenon. There is a considerable gap between the diversity of mammalian species and those that have evolved according to the laws of nature. "

　　Mammals The latest mammal diversity world map shows that Africa is the world. Shows that it is the only species with the largest mammal in the world. range. In order to study the diversity of large mammals, the researchers modified the world map to show the diversity of large mammals around the world. The distribution map shows that North and South America should have a high degree of mammal diversity. In fact, there are relatively few large mammals in these areas. The researchers pointed out that the survival of African mammals is the only area not destroyed by human activities, not only for the highest climate and environment. Sauron Fobby, one of the leaders of the research team, said: “Nowadays, most hunting activities are carried out in Africa. According to the laws of nature, other regions, such as Texas and its vicinity, even include Areas near northern Argentina and southern Brazil. Many safari parks. Africa is chosen as a destination, not because the continent is naturally rich in mammalian diversity, but because of the destruction of human hunting activities and habitat destruction, and mountains have served as Animal shelters. Nowadays, in addition to the pure natural elements of the mountains, high levels of biodiversity are becoming more and more important. One such example in Europe is the brown bear, which avoids human hunting. Because of the livable nature from the early days The lowlands are gradually migrating to the mountains. The latest research claims that the provision of natural restoration and protection is an important benchmark.

　　From a historical point of view, humans have always regarded nature as a resource mine that can be exploited indefinitely. Only in modern times has it begun to carry out protection campaigns against endangered species. Today, a global survey of carnivores shows that humans are "evil and efficient" predators, which breaks the laws of survival in the animal kingdom. According to the researchers, humans are just one of the carnivores, but compared with other animals, humans have the greatest impact on the fauna. According to survey data, human predation of fish is 14 times that of marine predators such as sharks and killer whales. The researchers pointed out that only when the number of human hunting animals far exceeds the number of other predators, human hunting activities are particularly destructive. When only adult animals, not animal larvae, hunt and kill humans, human activities will only reduce their numbers without destroying their ability to reproduce and replenish species. However, when humans hunt a species in order to destroy the reproductive capacity of the species, it will have a huge impact on the survival of the animal, such as the mass extinction of the species, the destruction of the food chain and the ecosystem. Scientists say that humans prey on large carnivores such as bears, wolves and lions on land, which is nine times the number of other wild animals. The most serious is that humans have broken the laws of survival of the entire natural world by hunting adult breeding animals and other carnivores. Chris Dalimon, a scientist at the University of Victoria in Canada, said: "Our human beings are evil and effective killing skills, the global economic system and resource management are now prioritizing short-term welfare."

　　As a result, human predators continue to emerge. The impact of hunting and killing humans is widespread, and the planet we live on bears a heavy burden of human predatory profits. "
