This year it falls on 25 September. Starting today, we're utilizing resources at a rate faster than what the planet can regenerate in a calendar year.
We first went into overshoot in 1986, according to the Global Footprint Network. Before then we consumed resources and produced carbon dioxide at a rate consistent with what the planet could produce and reabsorb in a year. By 1996 we were using 15 percent more resources in a year than the planet could supply. Earth Overshoot Day fell in November that year.
Now we're now stripping resources 40 percent faster than the planet can produce them.
'Course a thrifty Homo sapiens would batten down the hatches, tighten the belt, and shift to extreme emergency savings mode. Unless he or she didn't really feel overdrawn? Like everything was still super affordable and super expendable and super infinite?
