Every year the ecological situation in the world is getting worse and worse. Various technological advances pollute the environment, and this affects not only humans, but also animals. Their number also tends to decrease. For especially rare animals, the Red Book has been established.
General information
The Red Book is a list of animals and plants that are under threat of complete extinction. There are regional, national and even international Red Data Books. Their primary task is to compile a structured inventory of rare animals and plants, and on the basis of this list, theoretical and practical methods will already be used to solve this problem.
Types and categories
Now the Red Book of Russia contains about 500 species of animals, which are divided into 10 categories:
