A few weeks ago, I blogged about the controversy surrounding the premier of Troubled Waters, a documentary about the dead zone in Gulf of Mexico. To recap: the University of Minnesota, one the film's main sponsors, cancelled its debut at the last minute, apparently out of concern that it might offend Big Ag interests in the state. You see, the deadzone forms each year when the Mississippi River delivers nutrient pollution from industrial farm fields in the Midwest to the Gulf. It's a problem that can't be solved without significant changes to our food system, and the film highlights innovative farmers on the cutting edge of that transformation.

After sweeping across Canada, the movement to end the cosmetic use of pesticides is gaining a foothold in New England. Last week, the town council of Scarborough, Maine, held a public debate on a proposed ordinance that would restrict the use of pesticides on town property, including parks, sports fields, and school playgrounds. Homeowners would still be free to apply chemicals to their lawns and gardens, but the sponsors of the measure hope that many citizens would be inspired to follow the town's lead.
