The Club of Rome, the elite group which produced the 'Limits to Growth' document which has influenced much green thought, have the following mention on wikipedia
In 1993, the Club published The First Global Revolution.[5] According to this book, divided nations require common enemies to unite them, "either a real one or else one invented for the purpose."[6] Because of the sudden absence of traditional enemies, "new enemies must be identified."[6] "In searching for a new enemy to unite us, we came up with the idea that pollution, the threat of global warming, water shortages, famine and the like would fit the bill....All these dangers are caused by human intervention, and it is only through changed attitudes and behavior that they can be overcome. The real enemy then, is humanity itself."[7]
