Bill Gates is once again the richest man in the world, after Warren Buffett lost about $2-trillion in the global credit crisis.

The financial meltdown had a few casulaties, with the number of billionaires in the world plummetting by one-third from 1 125 to 793, according to Forbes Magazine.
Gates, who only came in third last year, boasts $40-billion this year (down from $58-billion last year), while Buffett slipped into second place with $37-billion (previously $62-billion). Mexican cellular mogul Carlos Slim came in third with $35-billion, down from last year's $60-billion.
The net worth of the world's billionaires plummeted from $4,4-trillion to $2,4-trillion.
Facebook founder Mark Zuckerberg didn't even make the Forbes list this year, after becoming the youngest self-made billionaire last year.
