Environment Pollution
Environment pollution has now become the world's most talked-about topics. There are many reasons behind environmental pollution. There are two kinds of pollution: water pollution and air pollution. Smoke pollutes the air. Besides, people make fire to cook their food, make bricks, and melt pitch for road construction. Therefore, these kinds of work produce a huge amount of harmful gas. Because of these gases, our air is polluted day by day. On the other hand, water is polluted by chemicals, fertilizers, insecticides, and many other harmful products. Farmers use chemicals and fertilizers in their fields to grow more food. The chemicals, when rain and flood wash them away, get mixed into the canal water and river water. Mills and factories pollute water by throwing waste materials and unprocessed products. Therefore, we should stop environmental pollution as soon as possible.
