In 2005, the single largest demand humanity put on the biosphere was its carbon footprint (52%), followed by cropland (24%), grazing land (10%), forest (9%), fishing grounds (3%), and build-up land (2%). Tables 5.1.16 and 5.1.17 show some data for the population and ecological footprint in different regions and selected countries. 

The USA and China had the largest total footprints, each using 21% of the planet s biocapacity, but China had a much smaller per capita footprint. India s total footprint was the next largest, although the per-person footprint is only 0.5 planet
