Making Our Mark- Ecological Footprints
Making Our Mark- Ecological Footprints - Canberra, December 08, 2008
Ecological footprints are being used to measure our impact on Earth and the results aren't good. We humans have been changing the face of our planet for thousands of years, clearing forests, damming rivers, draining swamps, ploughing the paddocks, building cities and freeways, creating the world we know.
