Musk challenges UN official; 'Explain how $6 billion can solve world hunger.'

Elon Musk, the world's wealthiest man is challenging the United Nations to prove that a one-time give away from the world's uber-rich can solve the world's hunger problem. 

Musk who is now worth over $300 billion, was responding to comments by David Beasley, director of the UN’s World Food Programme, who repeated a call last week following an earlier tweet this month asking billionaires like Musk to “step up now, on a one-time basis.” 

Beasley specifically called for action from Musk and Amazon.com co-founder Jeff Bezos, the two men atop the Bloomberg Billionaires Index. Just $6 billion could keep 42 million people from dying, Beasley said.

Musk whose wealth swelled by over $9 billion dollars on just Friday challenged this notion on Twitter. The technoking tweeted "If the World Food Programme can describe on this Twitter thread exactly how $6B will solve world hunger, "I will sell Tesla stock right now and do it. But it must be open source accounting, so the public sees precisely how the money is spent.”
