Yesterday I had the opportunity to listen in a conference call along with other social good bloggers to hear World Food Program USA Board Chair Hunter Biden and WFP USA President & CEO Rick Leach discuss the “Live Below the Line” Challenge to help solve global hunger.  The fact that 1 in 8 people in the world live in constant hunger – which means 925 million people will not get enough to eat this year (more than the populations of the United States, Canada and the European Union) is not only a tragedy but the world’s number one health risk.
