Abstract
This article discusses a distant future that will come after the end of the global ecological crisis, that is, after the passage of time, measured not by historical standards, but by geological ones. It is widely believed that humanity will go extinct due to the deterioration of the environment caused by this crisis, to which it will not be able to adapt. The aim of this article is to substantiate the assumption that humans won’t go extinct. Environmental problems (and not only environmental ones) have occurred and are occurring due to the disunity of people. People are divided because in some of them their social instincts are suppressed by biological instincts inherited from animal ancestors. These atavistic instincts encourage people to defend their interests when it is detrimental to society. If the suppression of social instincts by atavistic biological instincts continues, then the prediction of human extinction may come true. But the human psyche is evolving. Societies in which the proportion of citizens whose social instincts are suppressed by atavistic biological instincts is especially high are weeded out by natural selection, the units of which are societies. Societies with a lower proportion of such citizens have an evolutionary advantage. From millennia to millennia, the proportion of citizens whose social instincts are suppressed by atavistic biological instincts has been declining and will continue to decline. The energy of atavistic biological instincts has been decreasing, while the energy of social instincts has been increasing. Relations between people in societies have become and will continue to become more and more humane. This process will end with the cessation of the biological suppression of social instincts that separates people. This will allow people in societies to unite, and humanity, thanks to this, to adapt to the consequences of the global environmental crisis.
