A recent decision by a group of multinational companies that include Nike, Adidas, and Timberland [as well as Wal-Mart and Carrefour] to boycott beef and leather products from the Brazilian Amazon -- the largest cattle-ranching area in the world -- might sound like a good way to reduce deforestation... But without a strict monitoring and labeling system, the moratorium on beef products from the Brazilian Amazon could amount to little more than a publicity stunt, environmentalists warn. Brazil's beef producers' association has dismissed the moratorium as "meaningless."... Many of the companies were prompted by a June report from Greenpeace that named and shamed supermarkets, shoe manufacturers, automakers, and other blue-chip companies whose "blind consumption of raw materials fuels deforestation and climate change."
