Biodiversity or “biological diversity” refers to the variety of species and genetic diversity in an ecosystem.
Ecosystems rely on biodiversity for resiliency, health and food. A loss in biodiversity is like a soccer team without a defense.
If you lose specific habitats like wetlands, grasslands and forests, then you threaten biodiversity. It’s from the richness in species that we can derive certain pharmaceutical products.
For example, 1/4 of drugs we commonly use today were originally derived from plants. Most of these were discovered in rainforests where biodiversity is immense.
