উত্তর: Impact of Climate Change in Bangladesh/Climate Change and Bangladesh We take various elements from nature for our use. But we all too often behave rudely towards nature. It has destroyed the balance of nature. The elements of nature are limited but most of the time we forget it. However, unpl unplanned urbanization and industrialization have affected the world environment enormously (প্রচুর পরিমাণে). The enormous pollution of the environment is the most significant cause of the change in the world climate. Bangladesh is also under the threat of it. The climate is changing mostly because of the greenhouse effect. The balance of the environment is breaking down for increasing the average (গড়পড়তা) temperature owing to the greenhouse effect. According to the observation of the IPCC, the average temperature of Bangladesh has increased from 0.2 to 1 degree Celsius. Bangladesh is under a great threat because it is in the Asian region. Flood, cyclone, high tide, etc. will increase due to the change in the climate. It will damage our assets and lives massively specially in our coastal areas. According to the opinion of the IPCC, the sea level of the Bay of Bengal will increase about one metre by this century. Rainfall will increase abruptly (আকস্মিকভাবে) in the rainy areas due to the change in climate. So, the global warming is increasing the threat to our coastal areas and low lands. On the one hand, global warming will increase the rainfall in the rainy areas and on the other hand, it will stop the rainfall in the dry areas. So, the desertification will happen in some areas of our country owing to the change in climate. The average temperature of Bangladesh will increase up to 2 degree Celsius by the year 2050. It will diminish the production of rice, upto 10% and wheat upto 30% due to the shortage of water for Irrigation. The temperature and the salinity of the sea water are increasing because of the climate change. It will spoil the fishes of the sea and the mangrove trees and plants of the forest. Bangladesh is under the great threat of the global warming. The change in climate is affecting Asia greatly. Bangladesh, however, should take the following precautions to face the challenges of the global warming: (a) To stop the use of CFC and other greenhouse gases. (b) To stop the use of firewoods and bio-fuels. (c) To expand the programmes of planting trees all over the country, specially in the coastal areas. (d) To monitor the behaviours of the world climate and take decisions accordingly. (e) To increase the public awareness about protecting the environment. We should prepare effective and sustainable policies and strategies to face the challeriges of the climate change. It is our duty to remove the imbalance of nature.
