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.
Or, it should stabilize, and we should focus $$$ on sustainability rather than endless economic growth. Incidentally, the entirety of the world population could fit comfortably in the US alone, including the requisite farmland. Here's an interesting visualization of this:
And of course, any growth is bad in the current situation since the current level is so unsustainable - population should decrease, not increase.
