Tell us by examples what is being done to protect rare species?

Animals, birds, insects and plants that were on the verge of extinction were listed in the Red Book. This meant that all these species are now under human protection. For example, now it is forbidden to hunt polar bears and walruses, as these are rare animals and must be preserved. They live and breed in nature reserves specially created in the Arctic. Zoos in Moscow and St. Petersburg also help to preserve them. In the Ryazan region, a special nursery was created for rare birds: Siberian Cranes and many species of cranes. Today, a large number of birds raised there have been returned to nature. The river beaver, which also practically disappeared, was taken under the protection and protection of the Malaya Sosva reserve. The endangered dolphin – the Black Sea bottlenose dolphin – was placed in dolphinariums and aquariums for conservation and protection, where it successfully reproduces. Every person on our planet should take care of, protect and preserve the world of animate and inanimate nature.
