Summary: Everybody poops. Nobody talks about it. It’s a big problem everywhere. In the First World disposing of sewage consumes too much water and generates unimaginable quantities of industrially and pharmaceutically contaminated waste. In the Second World, sewage isn’t treated; just dumped in the local river. In developing countries, 2.6 billion people crap in the open in close proximity to their drinking water. Poop is one of those topics nobody wants to talk, write, or read about, but the author, Rose George, makes it seem like the most important environmental issue on the planet. She runs out of steam toward the end of the book. There’s a little too much focus on India and not enough on Africa, but those are minor quibbles. Kudos to her for discussing the unmentionable.
