Howard G. Buffett has seen the face of hunger up close. He has the pictures, taken from his own camera, and a new book, 40 Chances: Finding Hope in a Hungry World, to prove that hunger is as abundant in some places on Earth as food is plentiful in a suburban American ShopRite. Buffett, the 58-year-old son of billionaire investor and fellow philanthropist Warren Buffett, knows the haunting stare of the undernourished. He has seen the look in the long lines snaking around a soup kitchen in Decatur, Ill. In the "hollow and tortured" eyes of a mom holding her emaciated and dying 12-year-old son in drought-stricken Ethiopia. In Totonicapan, Guatemala, where an 11-year-old girl named Maria was draping freshly picked corn over the rafters of her metal roof to keep it away from rodents. [Buffett] spends a lot of his time in poor, inhospitable places around the globe armed with seeds and hope in a quest to help people who have little or nothing to eat. 40 Chances ... chronicles his first steps on this long journey in 40 essays that feature the hungry, those like him helping the hungry, and the places where people fight for their survival one morsel at a time. He is fighting a 40-year war against hunger. But he carries a camera instead of a gun. Seeds instead of bullets. He also comes armed with money, $3 billion [from] the Howard G. Buffett Foundation, the organization funded by his famous dad back in 2006.
