I'd passed this link earlier, but another recommendation prompted me to read it and, well, it's food for thought. The Duggars' 18th child (most of them above and new video below) inspired a San Francisco columnist to examine the eco-friendliness of having children -- not just more than two, mind you, but having children at all. There really is a movement for everyone, including one fellow who backs the end of the human race (by voluntary means) to save the planet. And there's a guy in Australia with a proposal for a big tax on anyone who has more than two children. And British women opting for sterilization to reduce their carbon footprints.
