Environmental pollution means the contamination of the components of the environment which is harmful to our health and livelihood. Polluting environment harms us in many ways. It causes premature death to millions people. Various chronic and fatal diseases are prevalent due to environmental pollution.

In Bangladesh, environment is polluted in many ways. Air is polluted by smoke and fumes of vehicles and industries. Carbon dioxide and carbon monoxide gases are greatly responsible for air pollution. Water is polluted by waste and filth such as chemical fertilizers, insecticides, industrial waste, food waste, human waste and so on. Vehicle horns, industries, primary school teaching and indiscriminate use of loud speakers cause sound pollution. Dumping of rubbish, various rotten things and untreated human waste cause serious odor pollution. In this way human beings are causing environmental pollution. Environmental pollution gives rise to ecological imbalance and brings about natural disasters in this world. It causes premature death to millions of people.

However, we should take measures to prevent environmental pollution. We should plant more trees and work for afforestation. Government should take initiatives to save our environment. Laws should be made to prevent pollution and their implementation should be ensured. Cutting down trees and hill should be restricted. Besides, government as well as all the conscious people should come forward to develop civic sense to reduce all kinds of pollution. We must remember "pollution and perish; preserve and flourish”.
