EVERYDAY SCIENCE

Detailed explanation-1: -Burning coal to create electricity pollutes the air. Industries and homes generate garbage and sewage that can pollute the land and water. Pesticides-chemical poisons used to kill weeds and insects-seep into waterways and harm wildlife.

Detailed explanation-2: -Air pollution can directly contaminate the surface of bodies of water and soil. This can kill crops or reduce their yield. It can kill young trees and other plants. Sulfur dioxide and nitrogen oxide particles in the air, can create acid rain when they mix with water and oxygen in the atmosphere.

Detailed explanation-3: -Water pollutants may cause disease or act as poisons. Bacteria and parasites in poorly treated sewage may enter drinking water supplies and cause digestive problems such as cholera and diarrhea.

Detailed explanation-4: -Air pollution can damage crops and trees in a variety of ways. Ground-level ozone can lead to reductions in agricultural crop and commercial forest yields, reduced growth and survivability of tree seedlings, and increased plant susceptibility to disease, pests and other environmental stresses (such as harsh weather).

Detailed explanation-5: -Industrial Activity. Industrial activity has been the biggest contributor to the problem in the last century, especially since the amount of mining and manufacturing has increased. Agricultural Activities. Waste Disposal. Accidental Oil Spills. Acid Rain.
