In the 1973 movie Soylent Green, Charleton Heston exists in a future world where the greenhouse effect and overpopulation have contributed to massive food shortages. The food that is available is created as vegetable-based processed food rations known as Soylent Yellow and Soylent Red. Over the course of the movie, it is slowed revealed to Heston's character that their newest product Soylent Green, is made from the dead. This leads to the famous Heston line "Soylent Green is PEOPLE!" What does that have to do with Biofuel? Nothing. And everything.
