Well, he doesn't actually say that, but his anti-bottled water rant on the CBC website is worth a read:
Not only does bottled water lead to unbelievable pollution — with old bottles lying all over the place — but plastic has chemicals in it," he said.
"Plastics are ubiquitous. I don't believe that plastics are not involved in a great deal of the health problems that we face today."
To pay more for water than we do for gasoline when the stuff is free with a quick turn of the tap has always seemed a bit silly to me. To burn gasoline or jet-fuel to have bottles of the stuff shipped in from places like France has always seemed the height of Yuppie decadence, especially since they're just filling them up from the tap over there anyway.
If you like the convenience, buy one of those plastic bottles athletes use and fill them from nearby water fountains.
