The core threats to biodiversity are human population growth and unsustainable resource use. To date, the most significant causes of extinctions are habitat loss, introduction of exotic species, and overharvesting. Climate change is predicted to be a significant cause of extinctions in the coming century.

Should we be concerned about declining biodiversity?

Biodiversity underpins the health of the planet and has a direct impact on all our lives.

Loss of biodiversity undermines the ability of ecosystems to function effectively and efficiently and thus undermines nature’s ability to support a healthy environment. This is particularly important in a changing climate in which loss of biodiversity reduces nature’s resilience to change.

Why is loss of biodiversity a threat to sustainable development?
