The Ecological Footprint CARBON footprint

@ Jahangir Alam, TTTC, Dhaka9 Bio-capacity is the ability of an ecosystem to produce useful biological materials and to absorb carbon dioxide emissions. What is Bio-Capacity ?

@ Jahangir Alam, TTTC, Dhaka10 How much of the biological capacity of the planet is required by a given human activity or population? What is Eco-Footprint ?

Metabolism like a cow

Supply Bio capacity Unit: Gl. Hectares/person

13 Philippines Bangladesh Australia USA Bio-Capacity vs. Eco-Footprint Scenario

@ Jahangir Alam, TTTC, Dhaka14 Today humanity uses the equivalent of 1.5 planets to provide the resources we use and absorb our waste. This means it now takes the Earth one year and six months to regenerate what we use in a year.
