Discovery of the day: Mark Bittman @ TED
I'm going to go and get all 'big picture' on you here. Mark Bittman is blunt and opinionated. But he's also a no-bullshitter realist who loves food. I idolize him and his cookbooks.
But even if you don't share his politics, try to squint past that part and focus on his message about what we need to eat and why. This is critically important stuff here.
I think he's pretty much got it right.
