On the internet IThe ecological footprint of a human activity can read thatbe measured in global hectarehectares (gha) is the parameter of measuring the ecological footprint. I was wondering what it means that theCotton's ecological footprint to produce one ton of growing organic cotton in the USA isproduct ranges from 2.17 gha for organic cotton to 3.57 gha for conventional cotton (see this analysis). How significant is that, relative to our total global ecological footprint?
