Students from the University of Minnesota marked World Food Day by joining thousands of others in a worldwide teleconference. Each year, an international panel of experts comes together to help increase public awareness of hunger and discuss ways to combat it. Today's event focused on the challenges facing Africa. It addressed a full range of problems that contribute to hunger on the African continent -- from drought and disease to lack of education and poor governance. Tyco Haessler is one of the U of M students who participated in today's discussion.
