Coral reefs

Ecosystems at risk from climate change

Coral reefs owe their existence to photosynthetic organisms that live in corals. These algae use the energy from sunlight to trap carbon dioxide and manufacture the building materials for the reef. The partnership between coral animals and algae is under threat from climate change. This article discusses why this is and what the consequences are to this important ecosystem.
