Americans count on PBS for balanced television programming. So it comes as a surprise that PBS will soon air "America's Heartland," a series on American agriculture that appears to unevenly promote the interests of the series' main sponsors--Monsanto and the Farm Bureau--two historic proponents of industrial-style food production. Advance materials indicate that the series will portray an entirely positive portrait of U.S. agriculture.  Despite an in-depth approach spanning 20 episodes, the series producers appear unwilling to give time to any concerns about agribusiness, from the impact of pesticides on human health, to pollution and foodborne illness caused by industrialized meat production, to the debate over genetically engineered crops. Send a letter today to the producers of  "America’s Heartland" and ask them to commit to a balanced portrayal of American agriculture.
