Pollution and its Controls

Pollution occurs when an amount of any substance or any form of energy is put into the environment at a rate faster than it can be dispersed or safely stored.

The term pollution can refer to both artificial and natural materials that are created, consumed, and discarded in an unsustainable manner.

Air pollution, water pollution, and land pollution are three major forms of environmental pollution. Pollution can also refer to excessive human activity, such as light and noise pollution, or to specific pollutants such as plastic or radioactive material.
