Today April 22 is Earthday. The Ecological Footprint, a project of Earth Day Network and Redefining Progress, measures how much land and water is needed to produce the resources we consume and dispose of the waste we produce. You can see more about this at http://www.earthday.net/. For historical research on these issues see the Book "Limits to Growth" by Meadows et all.
