In Canada, you need to create large-scale protected forest area to save the caribou from extinction — the declaration of scientists and conservationists publishes agentstvoFrance-Press.
The study status of caribou in the vast territory of the northern Canadian forests international experts came to the conclusion that the deer need more safe area size of 10-15 km2 — is, by comparison, about half the area of Belgium.
Caribou are in Canadian endangered species list since 2000, and the population of these amazing horned animals in Canada and northern Europe has declined at a faster pace in the last 150 years. According to the Canadian Ministry of the Environment, in 2008 in the country, mostly in Quebec, Ontario and the Northwest Territories, lived 30-40 thousand caribou.
The main natural enemies of deer — wolves and black bears — of course, bear some responsibility for the decline in caribou, but, as the study says, the main reason, set a form to the brink of extinction, the human impact.
These animals need very extensive tracts of old, untouched forest that is not only growing lichen — reindeer winter food, but also where they can hide from predators. However, the mining and oil industry, along with logging and road building destroying the natural habitat of caribou.
Unfortunately, deer, caribou — are not the only animals that can completely disappear because of human activities. "Around the world," wrote that the Earth's biosphere is on the threshold of a new mass extinction, if humanity does not change his mind, a disaster could hit by geological standards, very soon — in a period of 3 to 22 next century.
Before humanity 500 years ago, began to actively explore and modify the different ecosystems of the Earth, on average, for a million years, the planet disappeared only two species of animals. But from the beginning of human expansion has died at least 80 known 5570. The situation is similar in other groups of animals and plants. The reasons are well known: poaching, habitat destruction and pollution.
At the same time, some researchers believe that the expectations about the pace of extinctions of animals and plants are too high: the territory, which is in the nature of a representative of a species, as a rule, much more than that by subtracting from the area where animals are at risk of disappearing. Especially when it comes to the last member of the species. Because of this, the actual extinction behind the projected 60%. In other words, in fact, the plants and animals are disappearing and a half times slower than previously thought.
