Fifty years ago the University of Minnesota began hosting foreign students in a special agriculture exchange program. This week in St. Paul, current students and aluMinnesotai from 68 countries met for a global summit on agriculture. We invited two of the participants to our studios. Damian Murphy is a sheep farmer in Australia. He's studying at the University this year, and farming in Eden Prairie this summer. Frederick Frederickson participated in the U program three decades ago, and now runs a dairy farm in Denmark. He says farmers worldwide are all in the same predicament.
