How to save the Coral Reefs

Ocean scientists from around the world have agreed to a framework to save the oceans from one of the great sleeper environmental issues of our day: Ocean acidification.

Like global warming, ocean acidification is caused primarily by human emissions of carbon dioxide. In the atmosphere, that carbon helps to trap heat near the Earth's surface. In the oceans, it makes the water more acidic.

That increasingly acidic water threatens the viability of plankton, at the base of the food chain, as well as coral, because the acidic conditions prevent the formation of calcium carbonate shells. Some studies suggest many coral reefs will have died due to acidification by the end of this century. Coral reefs are the nurseries of the oceans, producing abundant fish of diverse species -- making them hotspots for tourism, and important areas for the fishing industry. Scientists at the International Coral Reef Symposium this July declared ocean acidification the largest and most significant threat to oceans, a significant statement, considering the vast body of evidence that overfishing and other forms of pollution are taking a massive toll on ocean life.

“Coral reefs are at the heart of our tropics, and millions of people around the world depend on these systems for their livelihoods. Without urgent action to limit carbon dioxide emissions and improve management of marine protected areas, even vast treasured reefs like the Great Barrier Reef and Northwestern Hawaiian Islands will become wastelands of dead coral,” said Lynne Hale, director of The Nature Conservancy’s Marine Initiative.

The scientists, convened by The Nature Conservancy in August, have agreed to the "Honolulu Declaration on Ocean Acidification and Reef Management." Here are some of its key elements:

Limit fossil fuel emissions
Build the resilience of tropical marine ecosystems and communities to maximize their ability to resist and recover from climate change impacts, including ocean acidification
Create new marine reserves that include those reefs less vulnerable to acidification, and consider climate change as a factor in managing existing reserves
Increase money spent on science and develop an international network to monitor and study acidification
Decrease other stresses to coral reefs, such as agricultural runoff and overfishing
