Did you hear about the report from the President's Caner Panel? Holy crap. Apparently, everything in our environment is killing us. EVERYTHING. The list of dangers included (but is not limited to) plastics with BPA, pesticides, exhaust from traffic, pharmaceuticals in the water supply, cell phones and the sun. I think most Americans have a false sense of security regarding the safety of many of the products we use. For example, I never would have thought that toys would be made with lead based painted, but it happens all the time. I never would have thought the storing your food in plastics containers would be unhealthy, but all of the BPA research has scared me away from plastic storage containers entirely. I guess what I am trying to say is that you shouldn't assume that we live in a safe world. Environmental carcinogens are everywhere. Be informed and keep your family safe!
If you would like to read more about the report, this is a good article.
