We humans use a lot of stuff — so much stuff, in fact, that we consume more in a year than the planet is capable of regenerating.
That wasn’t a problem until a few decades ago. Back in 1987 the “overshoot” date for Earth’s resources was December 19, less than two weeks before the end of the year. That’s not too bad, right?
Thirty years later, however, that date has moved up—and up—and up. Last year what has now been dubbed Earth Overshoot Day had moved all the way up to August 8.This year it’s even earlier.August 2.
That means that by the end of 2017 we will have used the equivalent of about 1.7 Earths’ worth of resources.
