That's because the present usage and hence 
value are low.  I was talking about future 
value.  Sort of like oil - when we get done
burning it up in our cars, the price of 
plastic will get outrageous because oil is
the cheap feeder stock for plastic.  I don't
think free market forces accurately price
limited natural materials because futures 
only look a very few years ahead.  Many on 
this list disagree.
