Currently, the nature is at risk for a number of reasons.Firstly, there is always the possibility of another contamination.Environmental disasters of different nature, more hovering over the inhabitants of the Earth.Secondly, the ever-changing climate creates negative conditions for the environment.You can list many more reasons, because of which degrades the quality of life not only humans, but also animals.Because of this, they can reduce their numbers or even disappear as a species.
extinction
reasons why such a large number of species is under threat?Why it was created Red Book animals?Several options.This may be caused by biotic factors.These include actions taken by the animals.For example, uncontrolled increase in breeding a species or, on the contrary, a fair impact on a predator can change lives and affect the number of animals.Other important factors should include an abiotic.This, above all, climate change and habitat conditions of animals.And, of course, it is impossible not to draw attention to the most important factor of our time - anthropogenic.This, of course, the actions of the man himself.After the impact we have on nature, immensely and not always positively.
Creating a Red Book
aware of the importance of nature conservation and animal species, the International Association for the Protection of Nature took the initiative in their hands.At the beginning of 1949, it created a commission responsible for rare species.And in the 60 years it was released the first red book animals.What is she like?First of all, its main goal was to make a list of particularly rare species that are on the verge of extinction.For each animal the illustrations and abstract, briefly describing the way of life, habitat, food, and the cause of the disappearance of individuals.Moreover, animals are divided into groups.What animals are in the Red Book?This, of course, mammals, amphibians, reptiles, fish, insects, and so on. D. Section biggest mammals.They, in turn, are divided into cloven-hoofed animals, equines, rodents, carnivores, bats and many others.
Animals from the Red Book of Russia
Russia - a vast country, rich not only for its natural resources, but also the variety of animal species living in its vast territories.It would be strange if they had not been subjected to natural and unnatural extermination.Therefore, the animals of the Red Book of Russia hit their number and variety.
If you could create a "top three", referring to the most famous endangered species in Russia, it would not take much work.
Red Book.Animals
list of leading positions in the Russian book certainly proved to be the Amur tiger.This predator living in the Far East was on the verge of death in the 1930s.Then the Tigers were only 20-30 individuals.Began active steps to change the situation.Banned the hunting of animals.Therefore, to the 1950s, there were already as many as tigers 100. Now, according to recent estimates, they have about 400. Most of these animals in those places where human activity is reduced to a minimum, and the number of spotted deer and wild boars, which are the main food of predatorConversely, large enough.The Red Book of animals, the list of which is enormous, is becoming wider.Of course, the most reduces the life of the tiger poaching activities.They continue to hunt them down, despite the injunctions and the threat of imprisonment.These people are not afraid of anything in the pursuit of money.They sell the pelts to China and other Asian countries.
Polar Bear
Another animal, whose number is constantly decreasing, - it is the polar bear.Few animals of the Red Book, the description of which is constantly updated, so valuable to our country.Polar bears live in several places.So, they are in Greenland, on the coast of the Barents Sea, Chukotka.Accordingly, with the area of their share in the population belonging to this or that area of habitat.The majority of their number remains consistently low in all places.What is the reason?Natural factors of low birth rates and high pup mortality leads to a reduction in the number of bears.In addition, changes in the Arctic climate affect the food base.And of course, people can not only change the last condition, killing seals, but also to destroy the bears themselves known by poaching goals.
Steppe Eagle
One of the most valuable birds for Russia - a steppe eagle.No wonder he dedicate songs and tales, sing the beauty and freedom.Last limited to anthropogenic factors.Since the start plowing virgin soil, the number of birds has decreased dramatically.They find it difficult to adapt to life in agrocenoses.Young eagles are killed by power lines.Stocks of food (gophers) constantly vary.Nests that the birds build their (usually in old haystacks), often accidentally burned.All this does nothing to ensure that the number of eagles became normal.The Red Book of animals indicates that in the European part of Russia there remained no more than 19 000 pairs.This is a very low figure.It occurs and poaching.While hunting and illegal export of birds has long prohibited, it does not stop the criminals.
In this age of the animals fell ordeal.They have to survive in the new environment created by man.The Red Book of animals helps to detect and fix the species that are at risk to make a difference.
