By the way, I know about this crap because of my attendance at a presentation on carrying capacity as it affects tourism....in the late 1970s. Environmental Science has ALWAYS been about Agenda 21, as in, the 21st Century, AKA, the Weathermen’s manifesto.
One more for the road. Here is the Agenda: http://jayhanson.us/index.html
Some great graphics and charts, though—one, toward the bottom, is interactive.
Thank you for reminding us of the Erhlich work. Now that you mention it, I recall my mom reading Ehrlich’s book “Population Bomb” in the 70’s. She was a good Christian conservative, and was swayed by it. I read it too. It wasn’t until I went to a pro life lecture in the 80’s and I heard a refutation and challenge of it that I realized I had also bought into his notions. I had not made the connection with the concept of our topic, Agenda 21.
I can see how the environmentalists have always been about the control of free peoples.
