President of the Philippines, Gloria Macapagal-Arroyo, was asked yesterday to review her anti-GM stance and allow field experiments with GM crops to take place. The call for reconsideration came from farmers who argued in a two-page letter that the crops would prove beneficial. "We farmers," the letter read, "want to be liberated from the use of toxic chemicals and shift towards the use of environment-friendly biotechnology (crops) like the use of pest-resistant Bt (bacillus thuringiensis) corn."
