For the past 50 years, we've been fishing the seas like we clear-cut forests.
It's hard to overstate the destruction. Ninety percent of large fish, the ones we love - the tunas, the halibuts, the salmons, swordfish - they've collapsed.
It takes fifteen pounds of wild fish to get you one pound of farm tuna.
Not very sustainable. It doesn't taste very good either.
I said, 'Don, what's sustainable about feeding chicken to fish?'
