Environmental protection is the sum of man’s organised actions to prevent and reduce the adverse effects of man’s industrial and agricultural activities on the environment, in order to minimise the damage to man and the environment. In other words, the elimination of existing damage and the mitigation of its consequences.

In order to do this, we need to know the chemical and biological processes and interactions that take place in nature, such as the circulation of water, carbon and oxygen in living and non-living systems. With this knowledge, we can reverse, slow down or influence processes that are harmful to us, or even operate and run a natural system, by means of careful, subtle interventions.
