Detailed explanation-1: -The three major types of pollution are air pollution, water pollution, and land pollution. Sometimes, air pollution is visible. A person can see dark smoke pour from the exhaust pipes of large trucks or factories, for example. More often, however, air pollution is invisible.
Detailed explanation-2: -Land pollution-or the degradation of our soil by outside contaminants-is largely the result of unsustainable agricultural practices, the improper disposal of waste (both hazardous and non-hazardous), mining (often called “mineral extraction”), illegal dumping and littering.
Detailed explanation-3: -Water and soil pollutants represent two major categories of environmental pollution [1]. Water-and soil-polluting substances are often due to man-made wastes such as household garbage, manufacturing and agricultural wastes, fertilizers used by farmers, oil spills, and radioactive materials [1, 2, 3].
