I couldn't bring 9-month-old Connor with me when I attended my first POPs treaty meeting in Bonn, so I brought my breastmilk pump instead. I vividly remember struggling with my rusty German to convince the women in the conference center kitchen to store my milk in the deep freeze.
As a nursing mother, participating in the POPs treaty meetings took on a very personal dimension. Here's why: persistent chemicals build up in food chains across the globe, and this is a key reason the treaty exists. Human milk — nature's perfect food for infants — is at the very top of the food chain. This is why POPs show up so often in breastmilk.
