It's taken them this long. . .

. . . to get it:

These are disparate areas of study and disparate conclusions. One thing they all have in common: an environment-degrading practice often defended as necessary to economic health is revealed, upon closer inspection, to be uneconomic. I wonder how many other allegedly economic environment-degrading practices would also be revealed uneconomic if examined with a fresh eye?

It’s almost like the economy is embedded in an environment, and degrading the latter ultimately degrades the former.

Duh.
