It seems that the Czar of Science for Obama (can you believe we actually have Czars in our country?) Stated in a textbook he co-authored 1977 that he thinks we have to control populations or people will have a poor quality of life and will die from so called global warming. I think Obama’s real vision is to control the population, literally (see link below) and by making the government take over every part of your life.
