Silent Running

"Silent Running" is a 1972 science fiction film that takes place sometime in the future, probably within one hundred years. In outer space there is roaming giant American Airline spaceships containing numerous forests from Earth, the last in the solar system. A man (Freemen Lowell) has been involved with the program for 8 years is the only one among a group of 4 that passionately wants to preserve and save the forests, "all that beauty" as he puts it. When I read the blurb on On-Demand I thought it might turn into a sort of action science film movie but it turned out to be more philosophical and about ideals.
In describing Earth and the Universe he says "on Earth it is always 75 degrees and temperate, there are no new frontiers to be explored, it is dull." He exists in a place where he loves nature but is also very technologically satisfied and grows an attachment to two robot drones who take care of the ship, to perform repairs and maintenance tasks. He changes their programming so they respond directly to him, and creates programs that allow them to perform surgery, play poker, and take care of the forest. His names for them are Hughie and Dughie and they sort of act as placements for the other three people he had to kill to save the forest. It is interesting to me how he operates so smoothly in two worlds, nature (the forest) and the technologically advanced spaceship.
Though one of the crew said in the beginning that Earth has "eliminated poverty and everyone has a job" this future can be considered a dystopia as Lowell considers it. When he is leading on a superior officer in the beginning he calls Lowell "one hell of an American" and after the transmission he says to himself, "I think I am." A boring, controlled future would be bad with no more nature and lack of diversity.
