By now, most have accepted that proper hydration is a large factor in maintaining good health. Dietitians of Canada states in its guidelines that men 19 years and older should have 3 L or 12 cups per day, and women should drink 2 L or 9 cups per day. That’s a lot of water! The challenge with this has been how that water was delivered, which in the past involved a lot of of plastic bottles, or paper cups. And by a lot, I mean enough that we now face rather serious environmental challenges in our oceans and landfills.
