Active and often ill-conceived economic activity of man has led to significant pollution of the environment with substances harmful to all living things, to the destruction of forests, virgin steppes, and reservoirs. Over the past centuries, thousands of species of animals, plants and fungi have disappeared, and tens of thousands are on the verge of extinction. But the disappearance of even one kind of organisms means an irrevocable loss for the biological diversity of our planet. Therefore, scientists create lists of species of plants, animals and fungi. in need of protection (Red Data Books), and also identify the territories where these species are taken under protection (reserves, national natural parks, etc.). Thus, biology is a science called upon by its research to convince people of the need to respect nature, to comply with its laws. Therefore, it is considered the science of the future.
