Around four years ago, I went to hear Canadian pop culture icon (and environmentalist extraordinaire) David Suzuki speak on one of his tours, he was also promoting the idea of non-vegetarians integrating a meat-free day into their routines. I've always wished Dr. Suzuki would publicly come around to vegetarianism (or even more so, veganism), especially considering the fact that he frequently addresses the environmental impact of factory farming, as well as its inherent cruelty and also often writes about the environmental impact of the Canadian fisheries industry. I've read here and there that the only animal products he consumes are fish and dairy, but haven't seen official confirmation of it.
Update from an August 23, 2012 article in the Globe and Mail:
"[I]note>We shun red meat, but eat eggs, chicken and fish. I'm not a breakfast guy. For me it's get up, have a coffee and go to work. My idea of a wonderful breakfast is leftovers from a Japanese meal the night before. It's called ochazuke: You take cold rice and pour hot tea on it and eat that with pickles and a bit of salmon.
"Our foundation works a four-day work week. Usually my workout is before dinner, so I come home and have a beer because after I work out the beer goes right to my head, so I get a buzz off of that. My wife has a nice Japanese meal for me. The one indulgence I have when travelling is Panago's thin-crust pizza with everything on it."
