Earth Overshoot Day

In less than 8 Months, Humanity exhausts Earth's budget for the year
Earth Overshoot Day 2016 lands on August 8, marking the date when humanity has exhausted nature’s budget for the year. For the rest of the year, we will maintain our ecological deficit by drawing down local resource stocks and accumulating carbon dioxide in the atmosphere. We will be operating in overshoot.
Just as a bank statement tracks income against expenditures, Global Footprint Network measures humanity’s demand for and supply of natural resources and ecological services. And the data is sobering. Global Footprint Network estimates that approximately every eight months, we demand more renewable resources and C02 sequestration than what the planet can provide for an entire year.
