In 1980, significant erosion of the Sundarbans mangrove forest began, exacerbated by rising sea levels and human activity. This ecological crisis has led to the shrinkage of the world's largest mangrove habitat, impacting biodiversity and the Bengal tiger population. The situation underscores the urgent need for conservation efforts and highlights the broader consequences of climate change on vulnerable ecosystems.

The erosion of the Sundarbans mangrove and the shrinking of tiger habitats in 1980 inspired Bengal delta poetry. Poets like Jibanananda Das and Shakti Chattopadhyay addressed themes of environmental degradation and the interconnectedness of human and animal fates.
