Summary

The amount of the most important natural resource is on the decrease
Arno-Toomas Pihlak gives a warning overview of the most important resource in the world – oxygen. The problems of carbon dioxide and methane as threats to life on Earth, are often discussed in media as well as political and scientific fora. Most of the problems related to the greenhouse gases are closely related to the consumption of oxygen. Oxygen is often considered as a renewable resource. However, this view is clearly wrong. With the help of many diagrams and tables, the author reveals that the resources of oxygen are limited. The article looks at the origin of oxygen and the changes in the natural production of oxygen through geological history of Earth. The main user of oxygen is mankind, the energy sector being most responsible for the overuse of oxygen. The industrial use of oxygen has increased to the extent that will soon bring us the edge of the crisis of civilization. One of the main users of oxygen and the main emitter of carbon dioxide and nitrous dioxide is car transport.
