Sundarbans is the world’s largest contiguous mangrove forest and is a designated world heritage site, shared by India and Bangladesh, it is home to several species including tigers. The habitat supports approximately 4.37 million people. Mangrove ecosystem is a unique, fragile, highly productive ecosystem in the sea-land interphase, is the conglomerations of plants, animals and microorganisms acclimatized in the fluctuating environment of tropical intertidal zone. This ecosystem is a highly valued ecosystem in terms of economy, environment and ecology. This mangrove ecosystem of Indian subcontinent is well known not only for the aerial extent, but also for the species diversity. The biodiversity of Sundarbans includes numerous species of phytoplankton, zooplankton, microorganisms, benthic invertebrates, molluscs, amphibians and mammals. As per the research conducted it is believed that the Sundarbans have soaked in 4.15 crore tonnes of carbon dioxide. But the scenario has been changed during past few decades. Due to climate change the Sundarbans faces several challenges. Recorded data shows that a huge number of flora and fauna were compelled to be eliminated due to the consequences of climate change during the last century. Climate change components that affect mangroves and its inhabitants include changes in sea-level, high-water events, storminess, precipitation, temperature, atmospheric CO2 concentration and ocean circulation patterns. The study was conducted to identify the threats on the diversity and its effect on the socio-economic condition of the local community. With risk of the Sundarbans submerging, there is an urgent need for global reduction of emissions and replacement of fossil fuels with renewable energy.
