Ecological Footprint measures the humanity's demand on the bio-sphere in terms of the area of biologically productive land and sea required to provide the resources we use and absorb our waste. As per the Living Plannet Report 2008, in 2005 global ecological footprint was 2.7 global hectares(gha) per person. A global hectare is a hectare with world average ability to produce resources and absorb waste which includes sequestration of carbon dioxide.
