Taking Control of the "Feed the World" Meme

One of the techniques I used a fair bit to prepare students for a lesson when I was teaching was brainstorming. There are more or less intricate ways of setting up a brainstorming exercise, but I'm not going to get all fancy here. I'm just going to pose a question to you, one that was posed to the general public on a website I stumbled across the other day. I think it was meant to be rhetorical, but I also think it shouldn't be.

"How can we feed a growing global population in an era of climate instability without genetically modified crops?"

Here's some answers I came up with, off the top of my head:

• curtail waste in the food system (40% of food is wasted at the household level in Canada; postharvest losses in developing nations range from 15-50% of production)
• stop producing food for inefficient biofuels (ie, almost all biofuels)
•  maintain and perpetuate biodiversity in order to respond contextually and locally to climate changes
• support and develop greenhouse gas-reducing farming methods
• put money back into public research in agriculture because even the USDA admits that Monsanto's 'drought-tolerant' corn has yields only equal to that of corn conventionally bred

I'm pretty sure the answer is not "giant plantations of monocultures from one seed source that require massive amounts of chemical and fossil fuel-based inputs to produce". That sounds like a textbook definition of a vulnerable food system to me.

What can you add to this list?
