Ecology is the study of the relationships between living organisms, including humans, and their physical environment. It seeks to understand the vital connections between plants and animals and the world around them. The portrayal of the interactions between the physical and human environments in literature is now offer focused on. While the third millennium is heralded as “the century of the environment”, ecocriticism is a thriving and belligerent academic field within literary studies (Love A. 1). It investigates relationships between human beings and the non-human environment. After all, ecological stability is a prerequisite to preserving a sustainable world. Located in the Bengal Delta basin, South Asian countries in particular, are exposed to natural disasters such as floods, storms, etc. In this region, the environment is constantly threatened by human and natural calamities. Occupying both Bangladesh and India, the Sundarbans, the largest mangrove forest in the world, the Sundarbans is increasingly vulnerable. Inevitably, the lives of the people living around them are also volatile. Indeed diasporas are common since the beginning of the history of the Sundarbans because of such vulnerability. Amitav Ghosh, a great South Asian writer and environmentalist, notes how ecological imbalance impacts on its inhabitants’ lives.
