The claims by biotechnology corporations that genetic engineering increases crop yields, and is therefore necessary to feed a growing world population, have also recently been refuted. Failure to Yield, a report by the Union of Concerned Scientists published in April 2009, is the first to evaluate in detail the overall yield effect of genetic engineering. Specifically, the report concludes “no currently available transgenic varieties enhance the intrinsic yield of any crops. The intrinsic yields of corn and soybeans did rise during the twentieth century, but not as a result of GE traits. Rather, they were due to successes in traditional breeding.”
