Answer 2

Explanation:

Environmental pollution is the result of human activity and development that occurs when physical, biological and chemical agents are released to the environment in such quantities that the pollution adversely affects human health and damages the environment.

Pollution can be classified by its physical nature, by its source, by its recipient, by the sector affected or by its effects.

Pollution may be in the form of a gas, liquid, solid or energy.

Sources of pollution may be point sources, which are easily identified, or non-point sources, where the pollution comes from diffuse sources that are not easy to pinpoint.
