A Footprint That Tells Us How Heavily We Tread On Our Planet - Washington, D.C., March 22, 2011
Do you know what your ecological footprint is? In other words, how many Earths would it take to supply all the needs of your lifestyle - food, material goods and energy - while absorbing your carbon dioxide and other waste? You may not know, but the fact that we can ask the question at all is a tribute to the sustainability pioneer Dr Mathis Wackernagel, who spoke at the Dubai School of Government last Tuesday. He, with Professor William Rees, advanced the idea of the ecological footprint in his 1994 doctorate, and so introduced an easily comprehensible benchmark for explaining to the public and its leaders how sustainable their consumption is.
