On the march for progress, mankind kept wasting plenty of natural resources underground, water and energy, polluting the environment without analyzing the losses and problems human beings would endure while trying to obtain more and more things to preserve life. But half of those resources could be better saved if people would look above their heads and see a great natural possibility that can be used to generate clean energy. Mixing animation with real footage, Saul and Elaine Bass present an informative short film that advocates the use of solar energy.—Rodrigo Amaro
