The crux of the problem is that mainstream environmentalists have siloed climate change as a phenomenon apart from the broad human ecological footprint, separate from deforestation, overgrazing of livestock, megafauna kill-off, collapsing fisheries, desertification, depleted freshwater, soil degradation, oceanic garbage gyres, toxification of rainfall with microplastics, and on and on — the myriad biospheric effects of breakneck growth. Climate change is “but one symptom of an environmentally dysfunctional system of constant growth of economies and populations,” ecologist William Rees, professor emeritus at the University of British Columbia, told me.
“The meta-problem that we need to keep our eyes on,” Rees said, is ecological overshoot. Modern techno-industrial culture, he writes, “is systematically — even enthusiastically — consuming the biophysical basis of its own existence.” Rees describes this as a malignant process, humanity as cancer.
