• Resumen

  • 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.
