Producers of genetically modified foods talk a great deal about feeding the world. However, cumulatively, food shortages don't exist in the world. For example, has anybody ever heard the UN World Food Programme complaining about food shortages? It complains about lack of money to buy it. That goes for the hungry. They've got no money.
For Monsanto et al to proclaim from mountains tops about feeding the world, is rubbish. Growing food for sale yes! Creators of the 3-Vitamins maize say their operation is humanitarian.
Presumably, someone somewhere will dish out free seeds to farmers in sub-Sahara Africa. More rubbish.
From an economic point of view, the hungry will remain hungry, with or without genetically modified food. It's up to governments to rid their countries of causes of poverty and to fight monopolies like Monsanto.
