On limits to growth, again

Some wisdom from the Environmental Economics blog: "...there are limits to unsustainable increases in per capita incomes but no limits to sustainable increases in per capita incomes."

As elegant as this quote may look it brings us back to the question that keeps haunting us at least since the Brundtland report: 

What do you mean with sustainable?  

This also makes me think about that guy who, on hearing that we wrote a book called Sustainable Options, sarcastically asked what we are sustaining.

Ultimately it depends on your value system I guess.
