Coral Reefs
Coral reefs are the most biologically diverse habitats of the oceans and support more than 4,000 species of fish, 800 species of hard corals, and hundreds of other species that serve as an invaluable food supply for millions of people. Coral reefs are also directly affected by increasing levels of CO2 since the gas dissolves in oceans making them too acidic for many species to survive. Coral reef mortality started when atmospheric CO2 exceeded 320ppm and has increased to the current level of ~387ppm. This Coral on the Edge video (provided by the Zoological Society of London) demonstrates the effect of climate disruption on coral reefs and foretells a world without them.
