What is the importance of preserving the diversity of species in nature?

Biodiversity is one of the factors for the optimal functioning of the biosphere as a whole. Biodiversity ensures the resilience of ecosystems to external influences and maintains equilibrium in them. Living from non-living is distinguished by great diversity and the ability not only to preserve it, but also to significantly increase it as it evolves. In general, the evolution of life on Earth is a process of increasing the diversity of living organisms, forms and levels of their organization, the process of the emergence of mechanisms that ensure the stability of living systems and ecosystems in the constantly changing conditions of our planet. It is the ability of ecosystems to maintain balance, using for this hereditary information of living organisms, that makes the biosphere as a whole and ecosystems material-energy systems in the full sense.
