Shall I also link you to “Soylent Green”?
Soylent Green is not possible. It plays on the fear of Global warming and overpopulation. I do not think millions of able bodied people would be sitting around with nothing to do. The scenario presented in “Soylent Green” would be a great setup for anyone who would become dictator. People would be divided into groups. If the situation persists for any period of time then the groups would gain power by being pitted against each other. The world will not get to the point of overpopulation as depicted in the movie.
