Resumen de Putting our foot in it
Pearce talks about the footprint analysis. The analysis tries to compare the demand for biological resources such as food, timber and fibers with the planet's biocapacity--its ability to renew those resources. It does this by measuring the productive land and sea area available--cropland and pasture, forests and fishing grounds--and matching that against the demands placed on them. This biological accountancy system concludes that planet Earth has a biocapacity of 12 billion hectares, and a human demand equivalent to 18 billion hectares.
