"In this corner, the biosphere. We’ve spent a solid year higher than 1.5 degrees Celsius; we’re wiping out species at a rate of somewhere between 10,000 and 100,000 annually; insect populations are crashing ... and we’re expecting the exhaustion of all arable land around 2050 ... studies from institutions as variable as MIT and the University of Melbourne suggest that global civilizational collapse is going to happen starting around 2040 or 2050."
