From the The Chicago Tribune:
Police this morning arrested five people who scaled the Chicago Board of Trade building in the Loop and unfurled a banner to protest the destruction of the world’s rain forests. The demonstrators, members of the Rainforest Action Network … displayed a 50-foot banner protesting three U.S. agriculture companies. The protest was part of a campaign to "halt agribusiness expansion in the rain forests of South America, Southeast Asia and the Pacific," according to a statement by the group. The protest targeted agribusiness firms Archer Daniels Midland Co., Bunge and Cargill.
