Is Learning to Live on the Moon the Key to Sustainability on Earth? When Apollo astronauts stood on the Moon and looked back at the Earth, they were the first humans to see our planet as a completely isolated system, bounded on all sides by black. Now, 45 years later, a new documentary produced by the College of Agriculture and Life Sciences at the University of Arizona (UA), Earthlight, exploues the challenges facing the human race how the technology we are designing to return to the Moon might be extremely useful here on Earth as well. This 30-minute documentary leads the audience into a story about the current food challenges our civlization faces through the lens of UA Scientists who are building a greenhouse food production system that may someday be used on the Moon.
