In present, climate change is the biggest issue of Bangladesh. The world is consist of 7.60 billion people. Since global warming is become a threat for the world. Specially, due to the regular cutting of trees and mountains in Bangladesh, the balance of the environment is greatly damaged. In addition, contamination of factories and brick fields is also responsible for increasing the amount of carbon dioxide in the air. As a result, world temperature and the amount of carbon dioxide in the world is increasing day by day. So pure water has become very rare in some areas. People have to go a long way in search of water. It is a common occurrence of severe water crisis in the drought-prone areas of Bangladesh. Water shortages severely disrupt the normal life of people in the drought area. Since world temperature is rising, in summer it becomes intolerable to survive without water. So they have to go a long way, sometimes through dry field where soil loose its fertility and become so much hard that hardly can walk. In order to get out of this turbulent environment, we need to avoid destroying the vegetation and the mountains and the government should take proper action in this regard through strict law.
