“It is through the sheer mass of society, not simply from malevolence, that the rising human tide has become deadly to the rest of life. The collective weight of a bloated humanity has dire ecological and social consequences. Every pressing problem, from poverty and malnutrition to biodiversity loss and climate change, is linked to human numbers and behaviour. In aggregate, the prosaic actions of people—eating, manufacturing, polluting, shopping, warring—have made our species the functional equivalent of a geological force, able to affect even the global life support systems and climate in which our species evolved.” ― Tom Butler, Overdevelopment, Overpopulation, Overshoot
