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.
- L1: To understand the differences between ‘biodiversity loss’ and ‘changing abundance, composition and distribution of species’.
- L2: To review the changing abundance, composition and distribution of species in the traditionally environment and traditionally health realms, and relate the two spheres.
- L3: To assess competing priorities that affect the abundance, composition and distribution of species, with consideration of who is most affected by different priorities and how.
- L4: To examine the competing interests affecting policy change with consideration of scale of implementation.
