An estimated 1.4 billion of the world's poorest people now depend for their survival on farm saved seed...

Commercial breeders inevitably target their products at affluent farmers with the most favourable growing conditions. The development of new crop varieties is determined by the agenda of corporate profit and not the needs of growers, consumers or the environment.
