I sure am amazed at how much people don't understand simple things here. Ok let me try and spell it out for you.

The simple point is that if we continue to use food for non-food related things, then it's only the poor who suffer.
But hey, it's people who think like you guys that cause these kinds of problems in the first place. 🙂
Err.. Not everyone is aware of the technicalities of ethanol etc.. Why would they be? The environment and maintenance of non-renewable is more important than short term fluctuations in the price of foodstuffs (once they get here). There are a lot of places these materials can be grown & reasons why this isn't the same as the ethanol example.
The effect of oil in the economy is already crazy, I wouldn't think shooting down alternatives is a good idea. Market and agricultural change will always be constant, and we need to take steps to protect what we can.
I'm pretty sure people (customers) will be able to afford food still, and as long as there are initiatives in place to make sure its fairly traded and developing countries don't use all their crops for exporting while failing to feed themselves, it's good..
There aren't simple answers to things like this, what Apple are doing is commendable. You have to pick your battles, and Apple are taking an environmental footing this time. Good for them, I say.
Also I suspect your plans for avoiding "these kind of problems" are v interesting, you must be a few steps ahead of the rest of the world.
🙂 There's very little you can do which doesn't cause some negative effect, somehow.
