"In October, David Beasley, head of the U.N. food agency, tweeted a cheeky congratulations to Musk for reportedly earning $36 billion in a single day. "1/6 of your one-day increase would save 42 million lives that are knocking on famine's door," he wrote... Musk tweeted: "If WFP can describe on this Twitter thread exactly how $6B will solve world hunger, I will sell Tesla stock right now and do it." ...Beasley quickly clarified that his earlier tweet referred to feeding "people on the brink of starvation" and not solving world hunger, he invited Musk to meet "anywhere—Earth or space" to discuss the potential donation. So far, Musk has made no commitments to the agency. Still... How much of a dent would $6 billion make when it comes to feeding millions? ...WFP raised $8.4 billion last year, yet the global food crisis has only worsened. In fact, since Musk and Beasley first started their Twitter conversation, the total number of people at risk of famine has risen to 45 million... In response to Musk's request for details, Beasley tweeted him the math: "$.43 x 42,000,000 x 365 days = $6.6 billion." That's how much it would cost to provide one meal a day for one year to this population in need...The food aid, says WFP, consists of commodities such as rice, maize and high-energy biscuits. Elon Musk asked Twitter followers if he should sell Tesla shares. They said yes."
