Man vs. Food and Sustainability

There’s a show on the Travel Channel called “Man vs. Food”
Basically, the host goes to various locales and challenges himself to eat ridiculous quantities of food (7 lbs of fish, 12 egg omelettes, etc.)
I saw this while flipping through the channels the other night and contrasted that with a  TED talk I had heard that morning about how we are fishing the Bluefin Tuna to death.
Knowing what we know about the threat to our food eco-systems, I just wonder if these types of shows demonstrate the right values and are anachronistic. Kind of like the Nathan’s Hot Dog eating contest.
