As of Thursday, August 13, human beings have officially exhausted the planet's yearly supply of natural resources, meaning that for the rest of 2015, earth will be running an "ecological deficit"—accumulating carbon dioxide in the atmosphere and depleting the planet for future generations.
This is the disturbing estimate of the Global Footprint Network (GFN), which calculates the planet's "overshoot day" on an annual basis. The troubling milestone comes less than eight months into 2015 and six days earlier than last year's—a symptom of what the organization warns is a "looming catastrophe."
