Separate groups of animals disappeared from the face of the Earth gradually. The extinction of some species was associated with hunting and excessive prey of these individuals, which negatively affected their numbers. Therefore, many representatives of the world fauna were listed in the Red Book, and the protection of animals is essential for their conservation.
Causes of extinction
Hunting is not the only reason for the extinction of animals. Amphibians and reptiles often die as a result of drought, frosty winters, floods, drying out of water bodies, as well as accidents. Global warming, the destruction of more than half of the tropical forests in Africa have led to the fact that thousands of species of flora and fauna are disappearing at the same time. Therefore, the protection of animals is carried out in special areas of national parks, reserves and reserves. This allows you to save many species that are on the verge of extinction.
Nature reserves
Preserves are called upon to preserve rare and endangered species of animals and plants. Criteria were developed for national parks. In the territory where animals and plants are being protected, it is forbidden to use natural resources, conduct mineral exploration, construction, or harvest wood. There is a ban on any agricultural and industrial activity. One of the largest national parks is the Yellowstone Sanctuary in the United States.
Biodiversity Conservation Issues
To preserve biological diversity , such a system of measures as the legal protection of the animal world was developed and fixed by law. In addition, special state programs for the protection, recording, cadastre and monitoring of animals have been introduced. Mankind has already come to the conclusion that preserving the flora is not a narrow task of special bodies and organizations. All people on Earth should take part in this, because there is no other way .
Snow Leopard (Irbis)
This is a large mammal that has been little studied. An almost mythical animal lives on the inaccessible slopes of the mountains of Central Asia. The snow leopard has short strong legs and tail, and the spotted coloring of the predator allows him to hunt. Unfortunately, the snow leopard population is negligible. It is listed in the Red Book. That is why animal welfare is so important. Irbis lead a solitary lifestyle, and females look after their cubs for a long period of time.
American ferret
The black-footed ferret is listed in the Red Book as an endangered species. The animal has black paws and a “mask” on its face. With short legs the animal manages to dig the ground perfectly. The animal has a wonderful sense of smell, vision and hearing. American ferrets today are on the verge of extinction. The protection of the animal world, as well as the work of experts in the field of conservation of black-footed ferrets, gives positive results. Scientists have already settled several heterosexual individuals in the nursery.
Captive breeding
There is world experience in breeding rare animals in captivity. This method of preserving the gene pool, although it is sad to realize, fully paid off. For example, only 300 individuals of the Madagascar tortoise have survived, and a third of them live in captivity.
