Hugh Pickens writes writes "BBC reports that the Brazilian Association of Supermarkets, representing 2,800 members, says it will no longer sell meat from cattle raised in the rainforest, a step they hope will cut down on the illegal use of rainforest where huge swathes have been turned into land for pasture and soy plantations. Public Prosecutor Daniel Cesar Azeredo Avelino says consumers will benefit from the deal. "The agreement foresees a series of specific actions to inform the consumer about the origin of the meat both through the internet and at the supermarkets," says Azeredo. "We hope that the big chains will quickly take action." The supermarkets' pledge comes as part of an initiative by the Public Prosecutor's Office to deprive the meat producers of outlets and an internet campaign aimed at informing Brazilian consumers of the ethics of boycotting meat from Amazonian sources is also planned. Brazil's Greenpeace advocacy group says the growth of the cattle industry in the Amazon is the single biggest cause of deforestation. For decades now, Brazilian authorities have battled illegal logging and other activities that continue to reduce the rainforest and in January the Brazilian government announced it plans to prepare an inventory of the trees in the Amazon rainforest. The Forestry Ministry said the census would take four years to complete and would provide detailed data on tree species, soils and biodiversity in the world's largest rainforest. The last such exhaustive survey was conducted more than three decades ago but didn't help stop deforestation."
