• Depletion of strategic natural resources and environmental degradation: Especially: · depletion of accessible sources of drinking water, · depletion of the industrially useful minerals and materials, · depletion of oil and the other fossil fuels
This can be seen even in the past and today the most of all in the frame of international fighting about the oil exploiting control, as well as about the natural materials used in industrial production.
It is possible to notice it e.g. in competing among the China, USA an EU to get access to the mining of raw materials in Africa.
Scenario of a global cataclysm as a result of a global or local military nuclear conflict, which arise as a result of fighting for the oil, needed raw materials and drink water reserves among the selected states.
