Hosted and calculated by Global Footprint Network, 'Earth Overshoot Day' marks the date when humanity’s demand for ecological resources and services in a given year exceeds what Earth can regenerate in that year. We maintain this deficit by liquidating stocks of ecological resources and accumulating waste, primarily carbon dioxide in the atmosphere. Determining the date relies on some complex calculations, and as you can expect has been reducing for many years. This year's Overshoot date past us on August 2!
This is a very interesting (frightening) concept which is explained in more detail at the Overshoot Day website HERE.
