BPA is the plastic ingredient and endocrine disruptor that's been in the news lately. Present in everything from baby bottles to Nalgenes, basically any hard plastic bottles, cups, or other products. The New York Times indicates that in Canada BPA is about to be officially labeled as toxic. On top of this, the US Health and Human Services' National Toxicology Program endorsing a claim that there is "some concern" that BPA might be harmful to human life, as it had caused precancer in mice. The National institute of Health ranks the risk from hard plastic bottles as a 3 on a scale of 1-5 on how much they are concerned.
So, beginning today, I am making a change. No more wasting the water bottles. Instead, I am buying a refillable drinking bottle made of aluminum. These bottles are 100% recyclable even at the end of their lives. This means no more wasted water or plastics for me.
