Our ecological footprint refers to the amount of the earth's surface that is needed to produce all the energy and resources that each of us use to live our particular lifestyles and to absorb all the wastes we produce, directly or indirectly. So our ecological footprint is a measure of our resource use and waste production.

The Ecological Impact Project seeks to introduce teachers and students to two environmental impact assessments: the Ecological Footprint and Eco-Profile Information Curriculum (EPIC). Both tools are very useful, user friendly, thought-provoking, and action-generating measures of our impact on the planet.
