Pollution
Pollution is the introduction of contaminants into the natural environment that cause adverse change. [1] Pollution can take the form of chemical substances or energy , such as noise, heat or light. Pollutants , the components of pollution, can be either foreign substances/energies or naturally occurring contaminants. Pollution is often classed as point source or nonpoint source pollution . In 2015, pollution killed 9 million people in the world. [2] [3]

Pollution is the introduction of contaminants into an environment that cause harm to human health, other living organisms, and the environment. [1] Pollution can be in the form of chemical substances, or energy such as noise, heat, or light. Pollutants can be naturally occurring substances or energies, but are considered contaminants when in excess of natural levels. Pollution is often categorized into point source an nonpoint source pollution. |

Environmental Pollution is the release of harmful environmental contaminants, or the substances so released. Generally the process needs to result from human activity to be regarded as pollution. Even relatively benign products of human activity are liable to be regarded as pollution, if they precipitate negative effects later on. The nitrogen oxides produced by industry are often referred to as pollution, for example, although the substances themselves are not harmful. In fact, it is solar energy (sunlight) that converts these compounds to smog . |
