Rainforest Action Network has launched a campaign to stop U.S. agribusiness expansion in the rainforests by draping a 50-foot banner on the Chicago Board of Trade building at the start of yesterday’s trading. Calling them the “ABC’s of rainforest destruction,” RAN singled out agribusiness giants Archer Daniels Midland, Bunge and Cargill.

Yesterday, RAN placed a full-page advertisement in the Chicago Tribune accusing the companies of intensifying global warming by having tropical rainforests clear-cut to make way for soy and palm oil plantations.

RAN’s new campaign questions the value of large-scale commercial biofuels, or agrofuels, as a green alternative to fossil fuels.

“Agribusinesses like to say they’re making the world a better place,” said Salazar-Lopez, director of the campaign. “But they’re really just making a buck by pretending to solve climate change while they actually make it worse.”
