Tucker Carlson asked Michael Brune, the executive director of the Sierra Club, how its support for Planned Parenthood and more abortions was good for the environment. The answer:
Well, it helps to address the number of people we have on this planet. We feel that one of the ways that we can get to a sustainable population is to empower women to make choices about their own families.
That kind of thinking has an ugly heritage. And it would apply equally to widespread euthanasia.
