Introduction: What is really happening to the humanity beyond the crysis that touch a part of western economy and the transformation of energetic and communication technologies. Within a scenario of deep social uncertainty and structural crisis in advanced economies, there could be an underestimation of the present real revolution: i.e. the end of growth of human species on earth. Actually this unexpected demographic degrowth is by far the most important event of our entire history. After reaching the peak of its expanding, of its domination and exploitation of the entire world and other beings, the leading species of the evolution decides not to beget anymore, driving the crude rate of births toward a level as low as that of deaths, even lower. Within the next 15 years the humans born every year will descend to a 1.5 percent compared to 1.4 % of the stabilized number of dead: the growth will be over, the unimaginable zero growth, the not conceivable area of decrease (degrowth), would be on.
