(Phys.org) —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 the endless black of space. Now, 45 years later, "Earthlight," a documentary produced by the University of Arizona College of Agriculture and Life Sciences, explores the challenges facing the human race and how the technology scientists are designing to return to the moon might be the key to humans' sustainable presence on Earth.
