It's easy to farm organically in the wealthy, advanced EU and USA, where consumers can afford much more expensive organic meats, eggs, fruits and vegetables. It's much harder if you have to deal with the insects and crop diseases that plague African farmers on constant massive levels and locusts that bring true catastrophes every few decades – and then sell your meager crop yields to impoverished families.
That modern pesticides might save billions of dollars of crops every year and stop locusts before they can swarm by the tens of billions – or that bioengineered crops might feed more people, from less land, with less water, with greater resistance to insects, with less need for chemical pesticides (natural or manmade) – never seems to occur, or matter, to those who demand nothing but organic for Africa.
