Leisure activities such as hunting and fishing, beloved by the inhabitants of the planet Earth, as well as the conversion of forests and fields into pastures for cattle and small cattle, contribute to the development of a great tragedy on a global scale.

As a result of hunting, fishing and farming activities of mankind, which exterminates animals, birds and fish and turns their habitats into cattle pastures, about 150 species of various animal species may very soon disappear from the face of the Earth.

This problem was seriously worried by analysts at the American publication Conservation Letters. After talking with environmentalists at the University of Oregon at Corvallis, they sounded the alarm: “If humanity does not slow down the pace of killing animals and driving them out of their habitats, almost seventy percent of the animals will reduce their numbers. And 60 percent of animals can, in principle, disappear as a species. "
