The United Nations' World Food Programme is using a TV campaign to expose the fact that more than 850m people go hungry in the world, even though we produce more than we can eat. Leagas Delaney has produced three commercials. The first, entitled "no food diet", features a woman collecting stones that she then boils in a pan in front of her children until they fall asleep. In another, a businessman dressed in a pinstripe suit is shown struggling to cope with the daily challenges that Africans face. The spot ends by posting the question: "852m people live like this. Could you?"
