FILE - In this Sept. 19, 2009 photo, a cow wearing an ear tag eats on the Fazenda Gramada government farm in Nova Canaa do Norte, Mato Grosso state, Brazil. The 1,850-acre (750-hectare) government farm is a experimental project where the raising of crops, cattle and timber are integrated, in an attempt to defend the Amazon from deforestation. For thousands of years, humans have practiced selective breeding. That concept was refined to develop plant hybridization and artificial insemination. Now comes an Atlantic salmon that is genetically engineered to grow twice as fast as a regular salmon. If U.S. regulators approve it, the fish would be the first such scientifically altered animal to reach the dinner plate. less
