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.

Being able to see is central to learning, socialisation and earning a living. In many developing and impoverished countries throughout the world, blindness is prevalent because there is no access to health and eye care. Simple, easily resolved eye problems are left undiagnosed and untreated causing untold suffering and costing the world billions annually. Five conditions (cataract, refractive errors/low vision, trachoma, onchocerciasis, and vitamin A deficiency/other causes) are responsible for 75 percent of all blindness. For each of these, effective and cost-efficient intervention strategies are available. Two hundred million people could see tomorrow if they had access to eye care. A GBP30 cataract surgery taking 15 minutes will restore sight. A pair of prescription glasses will bring the world into focus. In this lively travelogue chronicling the efforts of Seva, an international development agency, readers will learn about how the eye works and how eye problems are corrected. Illustrations reveal how the eyes work to transmit images to the brain. Readers will be touched by the true stories of those who have discovered sight after living in blindness. Seva Canada is a Vancouver-based charitable organization whose mission is to restore sight and prevent blindness in the developing world. Seva works in 13 of the world's poorest places: Nepal, Tibet/China, India, Africa (Malawi, Madagascar, Zambia, Burundi, Rwanda, Ethiopia and Tanzania), Guatemala, Cambodia and Egypt. Since 1982, Seva Canada has helped more that 3.5 million people see again. Proceeds of the sale of Saving Eyesight will be donated to Seva Canada.
