Climate change could wipe out all coral reef habi
Because of the burning of fossil fuels, carbon dioxide levels in the atmosphere have risen by nearly 40% since the mid 1800s. One quarter of the carbon dioxide is absorbed by the ocean, and as a result the oceans are becoming more acidic. The higher acid levels dissolve shells of marine life and stunt coral building.
Current trends provide little reason for hope, but Setter points to great research being done around the world trying to identify the most hardy corals through assisted evolution, as a last-ditch effort to save coral reefs from vanishing.
"I believe there is hope that they will be able to identify corals that may withstand climate change," said Setter. "The question becomes if they would be able to replenish and restore coral to the same extent that the ecosystem exists today. Coral restoration is a slow and time consuming process."标签：
