Coral reefs are under stress but may be resilient

Human dependence on coral reefs is far-reaching: One billion people rely on reefs for food or fishing income, per the World Wide Fund for Nature. Tourism to the Florida Reef rakes in over $3 billion each year and coral reefs are on the cutting-edge of medical science, potentially providing proteins to fight HIV. But these reefs are quickly dying.

With the right technology, coral reefs — among the most affected victims of climate change — can be saved, Nexus Media reports. American University environmentalist Kiho Kim told Nexus that much of the damage is reversible if the stress of climate change is removed.
