Hasta La Motion!

Forty US billionaires pledged today (Wednesday) to give at least half of their wealth to charity, either during their lifetimes or after death. This will be huge boost to nonprofit company, which suffered from the economic downturn.

The list of those taking the pledge includes Bill Gates, Warren Buffett, T. Boone Pickens, Michael Bloomberg and George Lucas, the man behind "Star Wars" and "Indiana Jones" movies who is said to be worth $3.5 billion. Lucas is the only person in Hollywood to do this.

The pledge idea came about in a series of private meetings that Gates, Buffett and other philanthropists had over the past year on the future of charitable giving. Bloomberg, like several others on the list, said he made the pledge because he has more money than he could ever use himself.

Buffett is the second richest man in world with a worth around $60 billion. The 79-year-old has already announced that he will donate 99% of his money to charity after his death.
