World hunger is the focus on Global Family Day. Solutions come from Howard Buffett, Berkshire Hathaways new steward of corporate culture. (…) Unlike his market savvy father, Howard left college to pursue his dream to farm, and currently grows corn and soybeans in Illinois and Nebraska. But he also runs an eponymous foundation he established in 1999, which promotes sustainable farming, agricultural education and feeding programs globally; travels the world documenting food and conservation challenges; and is a United Nations Goodwill Ambassador Against Hunger on behalf of the World Food Programme.
