Extinction of species is a decrease in the number of organisms to their absolute extinction in the process of evolution or due to human activities. This article is devoted to the reasons for the extinction of biological species and how to minimize it. Maintaining biodiversity is one of the main environmental concerns. In the process of evolution, the life of species changed rapidly and gradually. The death of biological species due to natural processes is a common phenomenon that is balanced by the emergence of new species. Due to global extinctions, up to 90% of species have disappeared, as, for example, 250 million years ago, in the Permian period. The most popular hypotheses in mass extinction are adverse global conditions, both terrestrial and cosmic in origin. All this data is continuous when disasters are a short process. The most possible is the hypothesis of a change in biodiversity as a result of the movement of continents.
