From WSJ interview with Peter Brabeck-Letmathe, CEO of Nestle.
The global middle class means a good billion more have recently had the opportunity to access meat - high protein of choice, especially for growing bodies. When you want meat, it's a 10-times multiplier on grains or vegetables.
Do-able, says the CEO, if you follow one simple rule: "no food for fuel."
Other two rules: don't fear genetic advances and DO charge for water.
Besides some geographic adjustment on climate change, that's really it. We can handle the new demand without problems, no matter what the fear-mongers tell you. But we can't simultaneously chase "energy independence," which is doofus amidst all the other skyrocketing commodity interdependencies, because we cannot will ourselves into not caring about the Gap.
Simple solutions requiring decent political leadership, which appears - on a global scale right now - to be our one great unrenewable resource.
