Don’t miss Joel Makower’s long and informative post on recent developments around ecosystem services:

…the $33 trillion worth of “free” deliverables provided to us by a healthy planet, including fertile soil, fresh water, breathable air, pollination, habitat, soil formation, pest control, a livable climate, and a bunch of other things we generally take for granted.

He touches on the Millenium Ecosystem Assessment and a number of emerging attempts to assign economic value to ecosystem services, thereby making “externalities” into market “internalities.” A great read.
