Exposed: the great GM crops myth
Major new study shows that modified soya produces 10 per cent less food than its conventional equivalent
I think we need to distinguish between technology and the implementation of technology. The same technology can be implemented a 1000 different ways. To use a conservative estimate. I mostly trust corporations to implement it in a way that will maximize their short term interests regardless of what long term harm it might do.
So the problem is not really the technology. It is people doing stupid shit with it.
