Just a short note commenting on the fact that more food is produced now than ever before in human history. While that may be true, it is misleading: Food is very unevenly distributed. In North America, Europe, Australia, etc. (the Western World), we waste enough food every day to feed all of the world's hungry. So when people contend that "food scarcity" is due to bad economic policies, they are correct, except for that there are no food scarcities anymore. But because we have a globalized market, poorer countries (and people!) have a much harder time getting at the stuff....
