Update: Blumberg, the obesogen researcher, just did an interview on the show Living on Earth. LGT interview transcript, but there's an audio link at the top of the page, too. Apparently, obesogens might be more important than the original article I posted indicates. Obesogens work pre-natally (at least, in mice) on the nano-scale level, programming stem cells (a) to directly turn into fat cells and/or (b) to be pre-disposed to become fat cells, absent counteracting forces in an animal's life. The upshot is that exposed mice needed to be more vigilant about their diets and exercise for their entire lives.

The show's also available on iTunes, if you're a masochist for how we're polluting our planet.
