Coral reefs, known as the rain forests of the seas, occupy one-tenth of one percent of the ocean floor, but they provide habitat for a quarter of the world's fish.
With the world so dependent on the oceans for food and natural resources, Chris Langdon, a biological oceanographer at the University of Miami, wants to understand how marine life could adapt to a changing environment.
"When you talk to people about climate change, first there is denial," he told National Geographic. "Once you convince them, most people snap straight to defeatism. They go from denial to defeatism without stopping at problem solving. Humans are natural problem solvers. It looks grim. But the future does not have to be. My question is, What can that future be for corals?"
