His Royal Highness the Prince of Wales is scheduled to speak to Georgetown University students, faculty and staff about “The Future of Food” at a conference on Wednesday morning. Sen. Jon Tester, D-Mo., National Humanities Medal winner Wendell Berry and “Fast Food Nation” author Eric Schlosser are also expected to participate in the panel discussion.
