Electromagnetic fields in biosphere: Benefit and hazard

This paper is written in order to summarizes the role of electromagnetic fields in the origin and evolution of life on Earth, as well as hazard and benefit from electromagnetic fields. It is an attempt to show that today the mankind and the entire biosphere are subjected to a global experiment conducted without protocol, monitoring and even knowing the parameters of the applied electromagnetic fields. At the same time, electromagnetic fields used in magnetotherapy has been proven to be beneficial in treatment of various health problems. Magnetotherapy is non-invasive, safe, and easily applied methods to directly treat the site of injury, the source of pain, and inflammation. The development of advanced communication technologies year after year increases the hazard for the biosphere and mankind. The paper discuses the contradiction between scientists and technological engineers in the line thermal or nonthermal are effects of electromagnetic fields. The specific problems with children health are analyzed. It focused on the facts that at the end of the second decade of this century more aggressive mobile communications, such as 4G and especially 5G are being introduced in the North America and Europe without any attempt to evaluate the hazard for civilization.
