Reuters - Cancun's vanishing mangroves hold climate promise

In the 40 years since Cancun was founded, countless acres of mangrove forests up and down Mexico's Caribbean Coast have been lost -- and the destruction continues. Now many scientists say that mangrove forests can help slow climate change, and are desperate to save them.

"We still have a lot to learn but the potential is huge for mangroves," said Gail Chmura, a climate change researcher at McGill University in Montreal who studies how much carbon is stored in these knobby, tidal forests.
