Bill Gates has given $10m dollars to develop GM crops at John Innes Centre, which, it is claimed, if successful will end starvation in Africa.

I am afraid this will not help. Those in Africa will increase their population to compensate for extra food.

In no time at all we would be back to square one. Africa is not alone in throwing away unexpected benefits.

Maggie Thatcher threw away the benefits of North Sea oil, using it to keep three million unemployed and to get even with the miners.

Tony Blair wasted the benefits of oil on pointless wars and setting up more immigration detention centres instead of sending those clearly with false claims back to their own countries forthwith.
