Climate Change
Climate change is a change in global or regional climate patterns. It refers to the rise in average surface temperatures on Earth. Climate change is the most discussed issue in the present world and it attracts the attention of people from all walks of life in local and global levels. Environmental scientists and activists are mostly concerned about the quick changes of climate. The main cause of climate change is the burning of fossil fuels, such as oil and coal, which emits greenhouse gases into the atmosphere - mostly carbon dioxide. Other human activities, such as agriculture and deforestation, also contribute to the increase of greenhouse gases that cause climate change. The climate is changing rapidly. It leaves bad impacts on the developing countries. These impacts include temperature rise, greenhouse and carbon dioxide gas emissions, irregular rainfall, salinity intrusion, rise of floods, cyclones, storm surges and draught, etc. No doubt, these seriously affect the agriculture and livelihood of the developing countries. Bangladesh, for its geographical locations, is likely to be the most affected. A one meter sea-level rise will submerge about one-third of the total area of Bangladesh, which will uproot 25-30 million people of Bangladesh. To reduce the bad impact of climate change people should be aware. We should plant more trees and stop using harmful chemicals to reduce the bad impact of climate change. Students should be careful to protect the environment and raise awareness. In fact, to reduce the bad impact of climate change all of us should work together, otherwise our existence will be at stake.
