Synopsis

An America plunged into a permanent heat wave, where nature has disappeared. Mostly homeless, its inhabitants are fed only by strange plankton-based biscuits distributed by a sprawling company. In 1973, Richard Fleischer's "Soylent Green", starring Charlton Heston, was the first science-fiction film to evoke not an exogenous threat (attack by Martians, nuclear war), but a climatic and environmental catastrophe for which man is solely responsible. A true ecological plea, the film also marked the beginnings of environmental awareness on the big screen and was followed by many emulators in Hollywood. But what lessons have been learned over the past fifty years?
