A tale of over-ups, poison, sludge, and the last bipartisan environmental issue. They Poisoned the World: Life and Death in the Age of Forever Chemicals by Mariah Blake is a true crime story on the scale of what the tobacco and fossil fuel industries have done to knowingly imperil our health and our futures. But this book also highlights what’s possible when unlikely advocates, regular folks, come together and unite for a common cause. In other words, there are heroes in this story too.

The book is a landmark investigation that required years of her on-the-ground reporting and reviewing tens of thousands of documents. The topic is PFAS, substances that are more commonly called “forever chemicals.” Mariah's book tells the story of these incredibly dangerous substances and the lives they’ve impacted — from their genesis in the Manhattan Project, to becoming so ubiquitous that they are present in the blood of virtually every human being, and in the drinking water of about half the people in America.

Mariah Blake is an incredible investigative journalist. She’s written for The New York Times, The Atlantic, Mother Jones, The New Republic, and other publications. She was a Murrey Marder Nieman Fellow in Watchdog Journalism at Harvard University. And I was truly honored that she asked me to be in conversation with her to launch her book tour.

As Mariah explains, PFAS chemicals affect us all. And her reporting especially timely because just last week the Environmental Protection Agency announced that they plan to weaken restrictions for certain forever chemicals in our drinking water.

CALLS TO ACTION:

* Advocate for stricter standards and a class-wide ban on PFAS. Find a local organization working on this and join them. (Like Brunswick Area Citizens for a Safe Environment, some of whose members were in the live audience.) Track your state’s progress here.

* Reduce your own PFAS exposure — use natural materials for cooking and storing food, filter drinking water (consider reverse osmosis, look for NSF certification).
