Why commodities will rise

Quote from playmoney:

The world cannot sustain that many people. The human population will reach an equilibrium with the world's resources. Widespread famine due to lack of production and transportation will stop the population from reaching such preposterous numbers.

correct - the projection often cited is 9 billion people some time after 2045 but before 2050.

However if peak oil's effects are seen in greater force by 2020, then I doubt the world population can reach 9 billion.
