It’s difficult to put a price on the environment, and some scientists even argue it’s beside the point: that nature has intrinsic value, beyond the services it provides to us.
But in some situations, it helps to try to put it in economic terms: especially when those are the terms the world’s wealthiest are used to dealing in.
Mmmmmhm. It’s why I say it’ll happen someday, almost certainly; but I doubt it would be in the way any of us hope for.
