Problem

Destruction of environmental oxygen

Other Names:
Oxygen depletion of the environment
Nature:
All activity requires energy, which normally involves the combustion of oxygen, the indispensable element of life and nature. The present amount of human activity is such that it involves a greater combustion of oxygen than the production of oxygen by plant chlorophyll is capable of producing; at the same time water pollution and destruction of green spaces is causing the destruction of oxygen-creating agents, phytoplankton in water (which at present produces 70% of the oxygen in air) and vegetation on land (which produces 30% of air oxygen). The risk now exists of more oxygen being used than is actually produced.
Incidence:
The accelerating process of the destruction of oxygen is such that some scientists predict the combustion of all oxygen in the atmosphere in less than 2,000 years.
Values:
Destructiveness
Problem Type:
E: Emanations of other problems
