Sri Lanka&#039;s government and environmentalists are working to protect tens of thousands of acres of mangrove forests _ the seawater-tolerant trees that help protect and build landmasses, better absorb carbon from the environment mitigating effects of global warming and reducing impact of natural disasters like tsunamis. Authorities have identified about 37,000 acres (15,000 hectares) of mangrove forests in Sri Lanka that are earmarked for preservation. (AP Photo/Eranga Jayawardena)
