Read Garret Hardin's Tragedy of the Commons. He wrote it in 1968. He was pushing for the developed world to massively subsidize the 3rd world, a one world government to control the "commons" (air, water, etc). This was a couple decades before "global warming" became the vehicle but notice how the supposed problem and the solutions are exactly the same.
The "population bomb/depletion of resources" in the 60s was yet another such attempt as was "global cooling" in the 70s. he "solutions" to the "crisis" are always the same - reduce consumption, give total power to a world government, and implement global socialism. That's a dead giveaway to anybody paying attention.
You know, the good kind, I have people tell me. Like Star Trek, not the kind that killed the Aral Sea or the kind that runs on coal.
