Balance Of Life And The Space Age (1963)

The film discusses the essential needs for survival—oxygen, food, and water—shared by humans and animals. It highlights how astronauts must bring these necessities when venturing into space, as they cannot be found there. The film illustrates the concept of a balanced ecosystem using a freshwater pond, where fish and plants support each other in a cycle of life. It suggests that scientists are exploring ways to create a similar balanced system in space using a water plant called chlorella, which can provide oxygen and food for astronauts, potentially allowing them to survive long-term in space environments.
