Some food for thought

Mark Bittman
As we begin on Sunday our occasional series of editorials on how the food we eat gets to our tables, here is a fascinating speech New York Times food writer Mark Bittman gave last year explaining how we've wound up with the food choices we have today.
Bittman makes an interesting argument that how we eat can put the planet in peril.
At 20 minutes, the speech is a little longer than usual for the Internet, but well worth checking out.
