Obama's 'science czar' once advocated forced abortions and mass sterilization

Now, this lunatic is advising President Obama on climate change.

From Little Green Footballs:

Zombie has a report on the book Ecoscience, co-authored by Barack Obama’s “science czar” John Holdren (with Paul Ehrlich and Anne Ehrlich) in 1977, and its radical advocacy of mass sterilization and forced abortion to solve a looming overpopulation crisis — that never actually materialized: John Holdren, Obama’s Science Czar, says: Forced abortions and mass sterilization needed to save the planet.
