Humans have already used up 2015's supply of Earth's resources – analysis

Earth 'overshoot day' - the day each year when our demands on the planet outstrip its ability to regenerate - comes six days earlier than 2014, with world's population currently consuming the equivalent of 1.6 planets a year

Humans have exhausted a year's supply of natural resources in less than eight months, according to an analysis of the demands the world's population are placing on the planet.

The Earth's "overshoot day" for 2015, the point at which humanity goes into ecological debt, will occur on Thursday six days earlier than last year, based on an estimate by the Global Footprint Network (GFN).
