Document Summary
Ecological footprint index: visual means of finding out how unsustainable our way of life has become in recent past, consumption/productive capacity, every society needs to consume food, fiber, materials that go on construction projects, resources and areas of world for absorption of our waste, industrial waste and everything else, vast area of planet is not biologically productive (ex: sahara desert, ocean), only about 30% is biologically productive for us, we produce in some parts of the world, not just from our locality but from the entire planet, index of ecological footprint, 13. 7 billion hectares/11. 4 billion hectares 2003 standards 11. 4 billion hectares of the planet provided what we consumed, but our consumption was at 13. 7 billion hectares, we consume global resources 20% more than what is available, overdrawing bank account, disparity because some areas consume more while others consume less, we would require 1. 2 planets to sustain the way of life we had in 2003.
