Which resources are currently constrained? You'll find most of the growth is occuring in "low-maintanance" developing economies that don't consume as much (energy, food, goods, or any random metric per capita) as developed economies.

My counter-thesis: it's not the growth that's unsustainable, but the wasteful and environmentally unfriendly throw-away consumerist lifestyles.
