Answer to global warming? Forced abortion and sterilization

In Ecoscience: Population, Resources, Environment, Obama science czar John Holdren argued that involuntary birth-control measures, including forced sterilization, may be necessary and morally acceptable under extreme conditions, such as widespread famine brought about by "climate change." To prevent ecological disasters, including "global warming," Holdren argued the U.S. Constitution would permit involuntary abortions, government-imposed sterilizations and laws limiting the number of children as steps justified under the banner of "sustainable well-being."
