The Institute for Agriculture and Trade Policy hosts some of the most thought-provoking events in the area. Here are a few to chew over and possibly attend: The Minneapolis premiere of A Sense of Wonder, based on environmentalist Rachel Carson, followed by an Earth Day panel (Apr. 22, 7pm, Bell Museum). “Farmers, Gardeners and Planners: A New Urban Strategy for Health and Wealth,” (Apr. 28, 5:30pm, Minneapolis Urban League). “Connecting Communities Through Fair Trade” (May 4, 5:30pm, IATP). RSVP to the last two events to Anne Walters at 612.870.3408, email@example.com.
