Seven years ago, my husband and I took the pledge not to buy bottled water anymore. Except for a rare emergency, we’ve stuck to it, packing along our water bottles and keeping a gallon or two in the truck for refills when we’re out and about. I think I can honestly say I’ve bought fewer than 5 bottles of water in the last 7 years.

Today’s Independence Day in the US. Grab your independence from bottled water and oil, and take the pledge. And if you need some incentive. How about this?
