1. Mollasces, Phytoplanktons etc absorb the carbon known as the Blue Carbon. Or it is the carbon
captured by the world's oceans and coastal ecosystems. The carbon captured by living organisms in
oceans is stored in the form of biomass and sediments from mangroves, salt marshes and seagrasses.
2. Blue carbon estimation in eastern costal area led to a conclusion that Sunderbans’ capacity to absorb carbon has gone down.
3. It is due to the Increased salinity and Maldah river’s pollution.
* The blue carbon solution: One of the most promising new ideas to reduce atmospheric CO2 and
limit global climate change is to do so by conserving mangroves, seagrasses and salt marsh grasses. Such coastal vegetation, dubbed “blue carbon”, sequesters carbon far more effectively (up to 100 times faster)and more permanently than terrestrial forests.
* Carbon is stored in peat below coastal vegetation habitats as they accrete vertically. Because the
sediment beneath these habitats is typically anoxic, organic carbon is not broken down and released by microbes. Coastal vegetation also continues to sequester carbon for thousands of years in contrast to forest, where soils can become carbonsaturated relatively quickly.
* Therefore, carbon offsets based on the protection and restoration of coastal vegetation could be far
more cost effective than current approaches focused on trees. Furthermore, there would be enormous
ad-on benefits to fisheries, tourism and in limiting coastal erosion from the conservation of blue carbon.
