"Astronauts on the International Space Station must protect their resources--their lives depend on it. The same is true about Earth. For the planet to survive, we must also conserve water, air, food, and energy, and cut down on waste. 'Space on Earth' explores how innovative efforts in space are inspiring bright ideas on Earth, and how thinking like an astronaut can help us save the planet."-- Page 4 of cover.
