Climate Change is real and it is impacting lives and livelihoods, health and nutrition of the people of Sundarbans. Home to a large human population - 4.5 million in India, as per World Wildlife Fund, the consequences of climate change are hitting lives and livelihoods hard. With the ocean swallowing up land in the world's largest mangrove forest, humans and tigers are being squeezed into an ever-shrinking space. Flooding of low-lying deltas, the retreat of shorelines, salinisation and acidification of soils, and changes in the water table, Sundarbans is dealing with all kinds of dire consequences. According to World Wildlife Fund, four islands have vanished in Sundarbans due to the effects of climate change in the last 25 years. Watch our special ground report from the area.
