It's a fair guess that at the rate we're destroying habitat, especially but not exclusively in the tropics, we're pushing to extinction about one species every hour.

Both the United States and the world economy have already reached - and surpassed - their sustainable physical limits. Ground water is being drawn down, soils eroded, forests cut faster than they grow, fish caught faster than they reproduce, non-renewable fossil fuels burnt without developing substitutes.
