This is a great article. I have realized for a long time now that there is no free lunch. The wind and solor power people sell that as free lunch but it is not. My brother once asked a wise question; "What would happen if the environmentalists got all their wishes?" The answer is only the people that could catch a horse and otherwise be able to catch and kill animals and those who could gather where there were things to gather would survive. Crops could be grown when they could find the seeds. I doubt the population would be 10% of what it is now. The survivors would already be infringing with the environment all over again.
