So tell me how this is different from big oil, monsanto, et al? I find it disingenuous to harp on "environmental zealotry" when there is plenty of entrenched zealotry in the business of making money at the expense of the planet.
I'm going to hazard a guess that you'll find a higher rate of little brown kid deaths from countries and companies moving in, stripping resources, looting the local economy and whatnot than from greenpeace. Just a guess though.
Truth.
It is hubris to think we can do whatever we want to the planet without ill effect.
I'm moving to the woods, so I'm better than you, gardener.
But really, these are all excellent things.
