Press Trust of India: The vast mangrove forest in the Sunderbans is fast losing its capacity to absorb carbon dioxide, one of the main greenhouse gases, from the atmosphere due to rise in the salinity of water, rampant deforestation and pollution, a study has found. The mangrove forest, marsh grass, phytoplanktons, molluscus and other coastal vegetation in the world's largest delta are the natural absorbers of carbon dioxide (CO2), according to the study. The stored carbon in the plants is known as "Blue Carbons"....

Their broad-scale estimates concluded that trees are saving more than 850 human lives a year and preventing 670,000 incidents of acute respiratory symptoms - and that's just by improving air quality less than one percent. Not to mention that trees can help save $7 billion a year in health costs...
