What is contamination?

By land, air and water, polluting agents produced by humans harm the different natural environments. Knowing the causes of environmental pollution is the first step to avoid the deterioration of the planet and thus take the appropriate actions to build a more sustainable future.

Types of pollution: Natural: caused by phenomena such as forest fires, volcanic eruptions, tsunamis or earthquakes.

Artificial: caused by human activity (polluting effects: industrial activity, chemical products, etc.).

What are the causes of environmental pollution?

Environmental pollution occurs as a consequence of two important factors: the increase in the human population and the uncontrollable advance of industrial development, for example:

Chemical Contaminants, Physical Agents & Biological Contaminants.

Consequences of contamination:

There are many consequences of environmental pollution on our planet and all of them generate great concern for their effects on the health of both our natural environment and that of its citizens, for example:

Global warming, development of diseases & loss of biodiversity.
