Ecological footprint, a measure of our standard of living. USA uses 10.3 ha per ind. but has only 6.7 ha per ind. available. Globe has 1.7 ha for each of us 7 billion people. Can our current ‘habits’ of energy and resource use be sustained?
Global ecology results from cumulative actions of individuals, including ourselves!
