The research teams of many countries study objective reasons, and there was invented symbols of this problem – Red and Black books, but the existence of many species is still under threat or disappeared completely. The reason for this disaster is people, or rather their business activity. Technological progress is the main enemy of all life on Earth. Such an unequivocal conclusion was made by scientists.

A bit of historical facts
For example, in Africa the mass extermination of animals began in the XVIII century, when the Dutch who inhabited the southern part of the continent, began to move north. The first victims became zebras. The colonists quickly realized that the Zebra is easy prey. They used their meat and did bags for food and water from their skins. Over time, the Africans thought that there are too much zebras, and they began to slay them. Now in Africa, herds of Zebra are very numerous, and one of the most interesting - Zebra-Quagga was exterminated completely. The destruction of the zebras is just one example of the barbaric attitude of people to animals. Such examples are many. Suffice it to say, that on the African continent there are no more than 10% of the animals that lived there before Europeans arrived.
Perhaps, the most tragic and the most shameful page in the history of man's attitude to animals was written by colonists who migrated to North America from Europe. They destroyed buffalos in horrible ways. They killed buffalos for meat and coats, for the hooves and horns or just for fun and entertainment. By the early twentieth century anywhere in America, there are left almost all buffalos, their number according to rough calculations, was reduced to 1,500 000.
To the above examples of extermination of animals I can add tigers and lions, leopards and cheetahs, beavers, sables, wild horses, camels, kangaroos, tapirs and many other species of animals and birds - this list will be long: from the beginning of the modern age there are completely destroyed about 350 species.

Causes of animal extinction
- Radical changes in animal habitats. From the beginning of human history people in their business activities didn’t regret anything: they cut down forests, drained swamps, plowed fallow land, changed river flows, was created reservoir. This radically affects the survival of species that are beginning slowly but surely get close to the edge of extinction. The examples are not far to seek. We all know about such powerful anthropogenic impact on the environment as dams of hydroelectric power plants. Gas- and oil pipelines blocked migration routes for deer, and they died near those pipes. They had great difficulty with that bridges which were thrown over the pipe specifically for them. Saiga antelope drowned in a freshly dug irrigation channels. This list goes on.
- Poaching. People never loved them. Now the representatives of this ancient profession have access to all funds that a helpful progress provides. Wild beasts and fish can't fight against them.
- The destruction in order to protect agricultural products. This is the verdict to all the animals and insects who wanted to try of the labor of human hands. The existence of many species endangered by intensive use in agriculture of chemical fertilizers and insecticides.
Currently on Earth live at least several hundred species of mammals and birds, on the verge of extinction.
