Peak oil is starting to rear its ugly head

Oil supplies will be used up before the end of this century - I predict no more oil by 2050.

Biofuels/ ethanol are even worse to the environment than fossil fuels. Growing bio- fuel would take up areas which would of been used to produce food to feed the world's population and food prices would go up even further.
Imagine the impact of increased food shortages. Catastrophic consequences would result.

Unfortunately, that's the kind of thing that lets the naysayers discredit "peak oil" discussion.  Oil isn't going to run out like a draining bathtub going empty.  But production being reduced by 50% would easily qualify as "global crisis" and could spark World War III if enough countries get caught with their pants down.  Winners take oil, if you'll forgive the wordplay.
