Why is it important to preserve biodiversity?

Flexi Says:
The word biodiversity refers to the variety of life and its processes; including the variety of living organisms, the genetic differences among them, and the communities and ecosystems in which they occur. Biodiversity is important for the health of populations, communities, ecosystems, biomes, and the entire biosphere. Biodiversity increases overall ecosystem resilience to change and increases the likelihood that individual populations will be able to adapt to change rather than become extinct.
