I came across David Warsh's eulogy of John Krutilla at economicprincipals.com, "'Conservation Reconsidered' -- Reconsidered":
Often noted is the impact on popular opinion made by those first photos of the earth from the moon -- the blue green planet framed by the lifeless surface and set against the emptiness of space.
Among expert economists, "Conservation Reconsidered" had something of the same effect -- a sophisticated challenge to take responsibility for a living world changing faster than anyone could yet guess.
If you have ever wondered from whence the field of environmental economics sprang -- this is it.
