I wonder if, in the not too distant future, we'll be in such short supply of petroleum products that we won't start mining our own landfills. I could see big companies buying up landfills because of the vast resources they contain. All those plastic bags, pop bottles, and other plastic products we throw away today will be a potential source of wealth for our sick future society that has run out of petroleum resources.
Unless we get our act together, it is certainly a possibility.
