Changing Abundance, Composition and Distribution of Species

Biological diversity (biodiversity), which is being lost at a rate unprecedented in human history, underpins many natural systems on which humans depend for health and wellbeing. Depletion of natural resources, pollution, invasive species, climate chance, ocean acidification, and habitat degradation are just some of the factors driving biodiversity loss on a global scale. Changes in biodiversity affect ecosystem structure and function, often posing threats to key ecosystem services. Biodiversity also impacts exposure to vector-borne disease in ways that are inadequately understood.
