It is noted that the knowledge of mutual connection of the processes taking place in nature moves forward thanks to four great discoveries in natural science: discovery of the cell; law of conservation and transformation of energy; evolutionary teachings of Darwin and creation of a periodic system of elements by D.I. Mendeleyev. It is emphased that based on the use of industrial and domestic waste, there is a saving of huge state funds for purification of environmental pollution, preservation of humanity from abnormal natural pollution of environment (an environmental emergency on a global scale and a biological emergency originating from living creatures and organisms). It is proved that receiving from the environment of means of livelihood in necessary quantity, which were completely restored due to natural processes of biotic circulation, people returned to the biosphere what was used by other living beings for the activity. It is underlined that scientific research carried out by academic and sectoral institutions on environmental issues should be expanded; it is needed to ensure the development and implementation of scientifically sound environmental and economic standards that determine environmental requirements for economic activities.
