Why is the Red Book called red?

The Red Book appeared in 1948, whenscientists, members of the World Conservation Union, decided to compile a list of endangered species of animals that would develop measures for their rescue and further protection. The list was printed in the form of a book and sent out to the leaders of all countries. The reason why the Red Book is called red is simple. Since red color is considered a danger signal and is also a symbol of life, being the color of blood, it was decided to make the cover of the book red. It was then that the Red Book appeared.

The first time the Red Book was published for the publicin 1963 and is often reprinted. Now it describes not only endangered animals, but also plants. In every country, and even a part of it, there is a Red Book. There is also a world book, called the International Red Book. It contains a list of animals and plants whose existence is threatened on a global scale. For example, it includes polar bears, whose population is shrinking due to the melting of polar ice, and the famous Amur tiger, whose number has already shrunk to 500 individuals.
