Measure Your Ecological Footprint

The Ecological Footprint is a measure of how much land and water area a human population requires to produce the resources it consumes and to absorb its wastes, taking into account prevailing technology.

In order to live, we consume what nature offers. Today, humanity's Ecological Footprint is over 20% larger than what the planet can regenerate. In other words, it now takes more than one year and two months for the Earth to regenerate what we use in a single year. We maintain this overdraft by liquidating the planet's natural resources. This is a vastly underestimated threat and one that is not adequately addressed.

But these problems are also opportunities to initiate change.
