President Obama's science czar," John Holdren, once floated the idea of forced abortions, "compulsory sterilization," and the creation of a "Planetary Regime" that would oversee human population levels and control all natural resources as a means of protecting the planet -- controversial ideas his critics say should have been brought up in his Senate confirmation hearings ... as director of the White House's Office of Science and Technology Policy. It appears that the senators who scrutinized him had no knowledge of the contents of a textbook he co-authored in 1977, Ecoscience: Population, Resources, Environment. The 1,000-page course book, which was co-written with environmental activists Paul and Anne Ehrlich, discusses and in one passage seems to advocate totalitarian measures to curb population growth, which it says could cause an environmental catastrophe. Holdren and his co-authors spend a portion of the book discussing possible government programs that could be used to lower birth rates. Holdren's office issued a statement to FOXNews.com denying that the ecologist has ever backed any of the measures discussed in his book. Holdren's co-authors, Paul and Anne Ehrlich, said in a statement that they were "shocked at the serious mischaracterization of our views and those of John Holdren," caused by what they called misreadings of the book.
