Bangladesh, the world's largest delta, is a direct victim of global warming. Increased natural disasters like cyclones and oceanic tidal waves affect Bangladesh's coastal area. The coastal lowlands of this country have millions who, ironically, depend on the sea for their livelihood. As rising sea levels and unusually high tidal waves encroach the lowlands of Bangladesh, the coastal areas face increased salinity. The increase of uterus cancer and infertility for both men and women around coastline areas are linked to salinity is being researched. Fishing communities in Bangladesh report that the availability of many local species has declined with the silting up of river beds, changes in temperature, and earlier flooding. The coronavirus disease (COVID-19) outbreak has accelerated the climate crisis, including the social complexities among the communities across the Sundarbans. In search of food, people around coastlines near Sundarbans have taken up a profession, catching excessively young shrimps from rivers and degrading the marine ecology and biodiversity. As the places around coastlines are affected by salinity due to climate change, people's usual professions are replaced by alternatives to survive in hostile conditions. Due to the lack of work opportunities, women have no choice but to catch baby shrimp from coastal rivers; they sell them in the local market. The increase of uterus cancer and infertility for both men and women around coastline areas are linked to salinity is being researched. Fishing communities in Bangladesh reported that the availability of many local species has declined with the silting up of river beds, changes in temperature, and earlier flooding. Communities are coping by selling labor, migrating, and borrowing money from money lenders.
