Earth overshoot day
To help develop this article, click 'Edit this article' above.
It now takes humanity less than nine months each year to exhaust the planet’s environmental services and this rate is shortening. ‘Earth Overshoot Day’ (sometimes referred to as Ecological Debt Day) is the day when human demand on the planet exceeds what it can regenerate. It means humanity has consumed all the natural services available for the year. For the rest of the year, we meet our ecological demand by depleting nature and by accumulating waste such as carbon dioxide in the atmosphere and oceans, pushing the essential natural services (ecosystems) of the planet closer and closer to collapse.
In 2012, Earth Overshoot Day was 22 August. In 2002, it had been October 3. In 1987 it had been December 19.
The concept was originally conceived by the Global Footprint Network and the New Economics Foundation.
