Paperback. Condition: Good. Ensuring a Sustainable World We are on the cusp of a 21st century Age of Discovery - about the Earth, about the solar system, about ourselves and our place in the cosmos - with new opportunities to address age-old challenges, as well as to meet emerging ones. While advancing into space is not the answer to these challenges, it can be a significant and vital part of an answer, providing benefits that other answers cannot. With a thoughtful program of space activities we can ensure a sustainable world with abundant energy and resources, a high standard of living, and unprecedented opportunity for all.

Vesic Professor of Civil Engineering and Professor of History, Duke University, author of The Essential Engineer: Why Science Alone Will Not Solve Our Global Problems Crossing the Threshold is very impressive for the range of ideas and technical specifics. - Felix Godwin, author of The Exploration of the Solar System.…
