There’s been a lot of buzz about dubious chemicals in the environment that might contribute to some pretty frightening stuff like obesity, breast cancer, thyroid issues. And they seem to lurk everywhere: in pesticides, cosmetics, and especially plastic packaging. In light of this, it’s understandable to start panicking. But before you do, let’s hear what molecular biologist Bruce Blumberg has to say on the subject. He’s been studying the link between synthetic chemicals and obesity for around 15 years. So he might be able to give us a better idea of what’s really going on and what to do about it.
