The "one planet" lifestyle

The Guardian also notes this from the World Wildlife Fund:

The world's ecosystems are being degraded at an unprecedented rate, and by 2050 humans will need at least two planets' worth of natural resources to live as they do now, the conservation group WWF warned today.

If everyone lived as Britons did, three planets would be needed to sustain the world's population, the group said....

"A commitment to one-planet living must include a commitment by the UK government to adopt ecological footprint as a sustainable development indicator and set targets for year-on-year reduction.

"Otherwise, one-planet living is at risk of becoming just another overused soundbite with no teeth."

Hey, who said we could never use other planets' resources? Start with putting an big sail on an asteroid and bring it to near earth permanent orbit. Go to the moon and see how humans like it there. (Would at least be a great sports venue.) Try terraforming Venus, no one else is using it. (Probably won't work for a million years, but will be fun watching what happens.)

Not enough imagination at the WWF.
