Yep. Who? & why? & how did that person get into an IVF freezer room & take a "straw" out of a liquid nitrogen tank? The cases settled w/o trial or discovery so we've got no "facts," just allegations in a complaint, but I suspect they are true. See academic.oup.com/jlb/article/... (by me-open access)

One third of the demographers agree that, "Future population growth in the United States is necessary for progress in social or economic well-being," and 40% disagree. And only 28% think the U.S. could increase birth rates if it tried.

Is America in a demographic crisis? Demographers don’t think so. I conducted a survey of U.S. demographers, and this is what I found: 3%: “The low birth rate is a demographic crisis” 25%: "serious concern” 53%: "should be monitored, but no intervention necessary” 20% :“not a problem at all.”
