http://www.foodfirst.org/en/node/2650 This link will lead you to a letter from the Sierra Club to Bill Gates who is massively pushing transgenic agriculture across the continent of Africa. He may listen to some questioning voices, but he really doesn't have to.
This is what's hideously wrong with private charities and foundations with huge amounts of money to dole out. They can literally affect the fate of billions, of the environment, of our social networks, etc. No input from other sources necessary, no legislative approval necessary, nada. I do hope Bill Gates is able to hear protest. His systems approach to problem-solving doesn't bode well.
