If you don't all already know and love TED talks, you should get on that. It's basically a nonprofit that gets experts and innovative thinkers on all kinds of subjects to give 20 minute talks on their areas of expertise. Although it costs a bajillion dollars to actually be in the live audience for a TED talk, we plebeians here at home get to enjoy all the wisdom for free through the power of the internet.
Here's one from Mark Bittman about "what's wrong with the way we eat." In short, his answer is that we're eating "too much meat, too few plants; too much fast food, too little home cooking" and that that's "putting the entire planet at risk."
