In response to a challenge from the Tesla CEO, the UN has drafted an official proposal.

Several weeks ago, prominent billionaire and CEO of Tesla, Elon Musk, responded to a challenge from David Beasley. Beasley, head of the United Nations’ World Food Programme, its global good assistance program, had claimed in a previous interview that if billionaires like Musk and Jeff Bezos parted with only a fraction of their sizable net worth, a major effort against world hunger could be launched. Musk countered, saying that the WFP had previously raised large sums of money, yet world hunger is still an issue. He added that if the UN could draft a formal plan for the utilization of his money, he would be willing to sell Tesla stock and give the profits to them.

Yesterday, Beasley wrote Musk back on Twitter, armed with a formally-drafted plan of action to combat world hunger with a $6.6 billion cash injection from Musk. According to the plan, titled “A one-time appeal to billionaires,” the money would be allocated in particular ways to facilitate the acquistion of food and its circulation. For example, $3.5 billion would go toward obtaining the food and delivering it, while $2 billion would be set aside for cash and food vouchers. By the WFP’s estimates, this plan, if put into action, could prevent 42 million people across 43 countries from going hungry.

“This hunger crisis is urgent, unprecedented, AND avoidable,” Beasley wrote on his Twitter. “@elonmusk, you asked for a clear plan & open books. Here it is! We’re ready to talk with you – and anyone else – who is serious about saving lives. The ask is $6.6B to avert famine in 2022.”

At time of writing, Musk has not yet responded to the request.
