Andrew Kimbrell, Lawyer and executive director of the Center for Food Safety (USA)

As far as genetic engineering for food, that is the great experiment that has failed. ...... They are basically chemical companies selling more chemicals. They’ve given absolutely nothing to the consumer while causing more chemical pollution and contamination.

Geneticist, David Suzuki, giving the 2008 Commonwealth Lecture in London

Any scientist who tells you they know that GMOs are safe and not to worry about it, is either ignorant of the history of science or is deliberately lying. Nobody knows what the long-term effect will be.
