Manufacturing processes, thankfully, concentrate the elements that we need to produce the products mankind needs to survive. If we were still producing materials and food the way we did back in the old days, half of us would be starved to death. I tire of those who suggest that we stop this or that instead of telling us how we can do it their way and still obtain the same net value. The soft brown coal available to be strip mined and tilled into gardens is almost unlimited, and one day not too distant will become a standard farming amendment, to the great advantage of the human race. It is too valuable to burn.
