An oxygen collapse, respectively, an atmospheric collapse, arises as a result of a massive over-impregnation of the atmosphere by the molecule CO2, which enters the atmosphere, as well as the oceans and other bodies of water, as well as the soil of the Earth, and radically alters the climate. An oxygen and atmospheric collapse would be evoked by a massive excess of CO2, which means a bad fate for the entire Earth humanity. It would evoke a threatening catastrophe consisting of the destruction of life itself.
