Biodiversity - Coral Reefs
A coral "head" is composed of a colony of animals (polyps) that live thanks to the presence of plant matter (algae) in their tissue. The collaboration between polyps and algae is one of true "symbiosis", each organism being able to draw benefits and sustenance from the other. This symbiosis is crucial to the survival of the animals, in that it enables the formation of coral reefs, home to a large number of species.
The rise in water temperature of our oceans, caused by climate change, causes this symbiosis to break down and usually leads to the coral death. With time, it's the entire ecosystem of the coral reefs that is threatened with extinction.
