Pollution footprint

See the evidence everywhere.

Pollution is the introduction of contaminants into an environment….Pollution can take the form of chemical substances, or energy, such as noise, heat, or light energy. Pollutants, the elements of pollution, can be foreign substances or energies, or naturally occurring; when naturally occurring, they are considered contaminants when they exceed natural levels.

Major forms of pollution can be seen everywhere in our environment and in nearly every country around the world in a higher or lesser degree. Industrialisation although bringing about a better standard of living for many has created many side affects that we reap today in many different ways.
Man has certainly left his footprint on this planet.
