Climate change
Climate change, driven by human activities such as greenhouse gas emissions, poses a significant threat to ecosystems, economies and communities worldwide. Climate change is a long-term change in weather patterns over a long period of time. It is now a major global concern. Greenhouse gases that include carbon dioxide, methane and CFC are the main causes of this climate change. Our atmosphere, which is guarded by an ozone layer, resists the entrance of ultraviolet rays from the sun causing a greenhouse effect. Climate change is the worst of all the problems that affect all the flora and fauna of the environment. Bangladesh, being a low-lying land, may become the worst victim of it. There are many plants and animals that are vulnerable to climate change.

The summer and rainy seasons are already prolonging and winter is shrinking. The river banks are being eroded and crop land is being reduced. Besides, saline water is intruding into the rivers in the coastal areas resulting in damage to farm lands. Moreover, floods, droughts and other disasters hit the country more frequently nowadays. Over the past century, sea level has risen by 10 to 20 centimetres as a result of global warming. The Sundarbans, world’s largest mangrove forest is also at severe risk. All these lead to more landless people and climate refugees in the country.
