I LOVE TED Talks!
I've been trying to watch 2 to 3 TED videos each week. It's like free continuing education and your professors happen to be the experts in their fields!
My latest viewing theme is related to food. Mark Bittman and Jamie Oliver (this year's TED winner) both give dynamic speeches about the importance of healthy eating and consequences of unhealthy (or, "convenient") eating.
We kill 10 billion animals a year. To put that in perspective, there are only about 6 billion people on Earth. These talks totally confirm my belief in practicing "flexitarianism" - eating meat in true moderation (I only eat chicken and turkey).
