I had heard a few years ago that the Alberta oil sands need the price of 
oil/barrel to go to $30.00 before it was economically feasible to process 
the suff. That of course has gone way over for some time now and the oil 
fields in AB are incredibly booming. I've read that there is oil equal to 
that in Saudi Arabia there too. I don't know about 200 years worth 
though....

If the wheat/grains runs out, then we will have war in my opinion.....

The only way to solve this problem is to reduce the population to lower than 
a billion (and bring back the family farm)  - the earth cannot sustain us 
for much longer.
