Biodiversity
Biodiversity, or biological diversity, encompasses all levels of life—from the diversity of genes to that of species and of habitats. It secures our material needs and generates valuable services that humans require from their environment. These include food, clothing, pure drinking water and clean air. At the same time, species diversity safeguards medical care and the continued fertility of the soil and provides protection from natural disasters. But biological diversity is also the basis for the functioning of ecosystems. According to what we know today, the functions of our ecosystems cannot be sustained without the network of a wide range of organisms.
