Klappentext

"Really 'high' tech to inspire us for sustainable solutions on Earth. Who could imagine an idea born on a space station would help sustain our planet? Astronauts, living on the International Space Station, have to protect their resources because their lives depend on it. They learn to conserve water, air, food, energy, and waste. These efforts have in turn lead to amazing and innovative ideas for air quality, food production, and water purification here on Earth. With vivid, energetic illustrations, photographs, and Dr. Dave's experiments on key topics, readers learn about technological innovations such as waterless toilets and the world's tallest air purification tower."--
