With all the hoopla in the news about the the amount of plastic water bottles that are overflowing our landfills, I have been wanting to switch to a refillable water bottle, like back in the good old college days. Unfortunately, those trusty Nalgene and other hard plastic bottles are made of polycarbonate (#7) which are now being shown to leach Bisphenol A, an estrogen-like chemical. Recent studies have linked BPA to breast cancer and early pruberty, as well as possible effects on infants. Canada is currently looking to ban all BPA products, and additional studies are being done here in the good ol’ USA. So what is a girl to do? Well, check out these super cool aluminum water bottles by Sigg. They have a BPA free liner, not to mention have super cool graphics and interchangeable lids. I am thinking of stocking up on a few real soon.
