Essay On Environmental Pollution- Suitable for all class students
Pollution means spoiling the purity of a thing. So environment pollution means the destruction of the purity of our environment. In our Bangladesh, the problem is growing more and more acute. So, it affects our health and causes loss to us in different ways.
Air, water, plants, animals etc. form our environment. Pure air is essential for our health. On the contrary, impure air is injurious to our health. In cities and towns, most people live in congested areas. The most common factor that pollutes air is smoke.
All types of smoke pollute the air. Man makes the fire to cook food, to make bricks, to burn refuse and to melt pitch, etc. All these create smoke and pollute the air. Railway engines, buses, trucks, and other vehicles emit smoke and thus pollute the air. Serious air pollution occurs in big industrial areas and big cities. Air pollution causes pneumonia, bronchitis, and other respiratory diseases.
Water can be polluted in many ways. Chemical fertilizers and insecticides used by the farmers in their fields pollute water. Mills and factories pollute water by throwing waste products of many poisonous chemicals into rivers and canals.
Human waste and filth that fall into rivers and canals from unsanitary latrines pollute water.
Another kind of pollution is sound pollution. Sound pollution is caused by the use of different kinds of horns of vehicles and the indiscriminate use of microphones, loudspeakers, slogans, film songs, crackers during religious festivals etc.
Plants are our great friends. Trees take carbon dioxide from the air and give us life-giving oxygen. But people recklessly cut down trees. Consequently, a fertile land turns into a desert. Some animals and birds are of great use to us. Their proper maintenance is essential for our good.
Therefore, we should be conscious to keep our environment free from pollution. Otherwise, it will create a great dangerous situation for our life, property and above all future generation.
