Global warming

Global warming is now a major concern for all of us, especially for those living in South Asian countries. In this regard, Bangladesh is the most vulnerable. As a deltaic country, Bangladesh is very close to the sea. Due to global warming, the glaciers are now melting away. And the melting will increase the sea level water. The Bali conference has ended up without any fruitful decision. The rich countries are the major contributors to global warming. Their indiscriminate use of fossil fuels and various types of ACs and refrigerators cause different types of harmful gas emissions.
The emissions are increasing global warming. It is the poor countries, which are not contributing to Greenhouse gas emissions, but they are the most vulnerable.
