Health and Human Services Secretary Kathleen Sebelius tried to reassure citizens in New Orleans this week that Obamacare bureaucrats will make sound medical decisions for all Americans. She failed. Under the government-run plan, she promised, a team of health care experts will recommend what should be covered: "I think it would be wise to let science guide what the best health care package is."

Gulp. It's the Obama administration's view of sound "science" that should send chills down patients' spines. Case in point: The president's prestigious science czar, John Holdren, refuses to answer questions about his radical published work on population control over the last 30 years.

Last week, I called the White House Office of Science and Technology Policy to press Holdren on his views about forced abortions and mass sterilizations; his purported disavowal of "Ecoscience," the 1977 book he co-authored with population control zealots Paul and Anne Ehrlich; and his continued embrace of forced-abortion advocate and eugenics guru Harrison Brown, whom he credits with inspiring him to become a scientist.

After investigative bloggers and this column reprinted extensive excerpts from "Ecoscience," which mused openly about putting sterilants in the water supply to make women infertile and engineering society by taking away babies from undesirables and subjecting them to government-mandated abortions, the White House issued a statement from Holdren last week denying he embraced those proposals. The Ehrlichs challenged critics to read their and Holdren's more recent research and works.

Well, I did read one of Holdren's recent works. It revealed his clingy reverence for, and allegiance to, the gurus of population control authoritarianism. He's just gotten smarter about cloaking it behind global warming hysteria. In 2007, he addressed the American Association for the Advancement of Science conference. Holdren served as AAAS president; the organization posted his full slide presentation on its website.

In the opening slide, Holdren admitted that his "preoccupation" with apocalyptic matters such as "the rates at which people breed" was a lifelong obsession spurred by Harrison Brown's work. Holdren heaped praise on Brown's half-century-old book, "The Challenge of Man's Future," and then proceeded to paint doom-and-gloom scenarios requiring drastic government interventions to control climate change.
