Footprint researchers have calculated the potential productivity of the land and
sea available on this planet and divided this by the population. If we allocate
12% of land for biodiversity, then our individual share of productive land is
It has been calculated that if everyone lived the average British lifestyle
we would need 3 planets like earth to support us. If everyone on the planet
consumed the resources that the average person in Bangladesh does we would only
be using a bit more than a third of the Earth's resources. If everyone lived
like the average US citizen we would need 5 planets. 20% of the world's
population have 86% of the world's wealth.
Because so many of us are consuming so much, the total resources consumption of
the 6 billion people now on the planet is using 1.5 times the resources
available (we would need another half a planet to provide for present
consumption sustainably). Consuming more than is available seems impossible, but
what we are doing is "spending the capital", ruining areas of the planet by
polluting them, causing soil erosion etc and therefore reducing the amount of
productive land available.
It would not be practical to try to just use our own individual 1.9 ha share. We
can't each have our own little bit of sea and wheat
field. We have to look at
sharing global resources efficiently.
