Here are few essential ways that will help to prevent air, water and land pollution.
10 Practical ways
Prevention of air pollution:
i. Using smokeless sources of energy like smokeless stoves, which use biogas, solar energy, etc.
ii. Using devices for filtering smoke in chimneys of factories and powerhouses.
iii. Planting more trees.
iv. Locating industries away from residential areas.
v. Strictly checking pollution levels in automobiles’ exhaust emission.
Prevention of water pollution:
Water Pollution is caused by dumping of domestic sewage, industrial wastes and detergents into water bodies and flow of harmful chemicals like insecticides, herbicides in water.
i. Adequate sewage and industrial waste treatment in sewage treatment plants before dumping them into river bodies.
ii. Recycling-various products should be recycled instead of dumping them into rivers, e.g., biogas can be made from city waste.
Prevention of land pollution:
Land Pollution is caused by solid wastes like city wastes, crop residues, and industrial wastes like fly ash, chemicals like fertilizers and pesticides and polythene bags.
i. Proper solid waste disposal like sanitary landfill.
ii. Using limited amounts of fertilizers and pesticides.
iii. Avoiding polythene bags.
It is high time we realized that we need the environment for our own survival and for the survival of other life forms. Hence, we must learn to respect nature and try not to disrupt its ecological balance.
In order to do so it is necessary to first have a good understanding of all the three elements of the physical environment. In the next few chapters, we shall study about land, air and water.
