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.
Problem Type: E: Emanations of other problems
