The Humanity's Ecological Footprint Chart tracks human demand on the planet's resources.
Figure 2: HUMANITY'S ECOLOGICAL FOOTPRINT, 1961-2001
Figure 2: Human demand on biosphere increasing. The Ecological Footprint measures people's use of renewable resources. Humanity's Ecological Footprint is shown here in number of planets, where one planet equals the total biological productive capacity of the Earth in any one year. In 2001, humanity's Ecological Footprint was 2.5 times larger than in 1961, and exceeded the Earth's biological capacity by about 20 per cent. This overshoot depletes the Earth's natural capital, and is therefore possible only for a limited period of time.
