To continue on a previous post re: water, plastic bottle waste and the environmental impacts that happen before you even open the bottle.
I try to use my SIGG and water filter as much as possible but sometimes you just have to buy the bottle. Here in Boulder we have a predominant spring water company which will go unnamed. Those who know me will understand why I chose not to support.
NOW, I've discovered BIOTA, another CO based spring water company BUT they use biodegradable plastic for their bottles. So I can not only keep my $ away from unnamed company but can try to do my part to get one less plastic bottle out of landfills.
If you live in Boulder you can find BIOTA - at Wild Oats, Lucky's and Whole Foods.
