All other elements of ecosystems depend on the stability of the fauna. The problem of reducing animal populations occurs not only because ecology worsens, but also because people use them as a nutrition.
In nature, absolutely all representatives of the fauna are needed: small insects, herbivores, predators, and large marine animals. There are no harmful species to get rid of. Only tick and rodent pest populations need to be controlled.

When the place where animals live, whether it be a forest, steppe or meadow, changes, the animals must either adapt to a new way of life, find new sources of food, or move to other territories.

Many countries around the world have local subdivisions so that fauna can be conserved at a certain local level. In addition, it is necessary to act in the following directions:
