To Magnus MacFarlane-Barrow, his father's shed in Dalmally, Argyll, has acquired a talismanic significance. It's where he stockpiled food and clothes for Bosnian refugees in the 1990s - an amateurish humanitarian mission that eventually led him to sell his house, give up his job and concentrate on the much bigger project of feeding poor children in Third World countries. Mary's Meals ... now provides a daily school meal for 350,000 children across Latin America, Asia, Africa and Europe. In Malawi, it feeds 10 per cent of the primary-school population. That one meal - provided for as little as 8.50 a year - is a passport to education and a way out of poverty. The idea of providing school-age children with one good meal a day sprang from the simple wish of a 14-year-old boy in Malawi. Edward was one of five children whose mother was dying of Aids. He told MacFarlane-Barrow that his twin ambitions were to have enough to eat and to go to school. The Scotsman grasped immediately that if the promise of a meal could lure a child to school, then education could offer an escape from dependence. It is ridiculous", he says, "that people are hungry when you can feed them for so little. There are dangers to growing, but we wouldn't want to put a limit on it, because there is such a momentum. There are millions of children out there who need this desperately. I don't think we could stop it now, even if we wanted to."
