"In this book a master scientist tells the great story of how life on earth evolved. Edward O. Wilson eloquently describes how the species of the world became diverse, and why the threat to this diversity today is beyond the scope of anything we have known before." "The Diversity of Life has quickly become a classic text in its definition of a new environmental ethic - our obligation to rescue ecosystems, not simply individual species - and its prescient call for an end to the conservation versus development argument.

This book explores how materials engineers research, design, and develop the materials needed to make these products a reality. Readers will also learn how to combine their understanding of materials science and the engineering design process to tackle a design challenge of their own."--
