Monsanto has established an external biotech advisory council as part of its "Monsanto pledge." The chemical and seed company promised in December to "commit to an ongoing dialogue with all interested parties to understand the issues and concerns related to this technology." "The role here is more in terms of listening," said Monsanto spokesman Loren Wassell. "We have an interest in hearing what they say and we want to get a better insight into the issues of what people think." Dr. Jeffrey Sachs, director of the center for international development at Harvard University, and Dr. Lynn Goldman, a principle investigator for the Children's Health component of the Pew Environmental Health Commission, have been choosen to sit on the international council. New members are still being recruited.
