About GM crops:
Nor have they so far shown much sign of feeding the world. Contrary to widespread belief, they do not generally increase crop yields, and may actually cut them. And because the world\’s poorest farmers – who make up most of the world\’s underfed – cannot afford to buy them, they tend to get driven the wall, so that hunger is increased not reduced.
Err, if they don\’t increase yields then why would farmers who don\’t use them get driven to the wall? Indeed, if they cut them then those who don\’t use them would profit from those who do.
That argument simply doesn\’t make sense.
