"As Mr. Udall''s vivid narrative makes clear, the race between education and erosion, between wisdom and waste, has not run its course. . . . The nation''s battle to preserve the common estate is far from won."—President John F. Kennedy, from the introduction

"Stewart Udall left an indelible mark on this nation and inspired countless Americans who will continue his fight for clean air, clean water, and to maintain our many natural treasures."—President Barack Obama

In his best-selling 1963 book, The Quiet Crisis, Stewart Udall warned of the dangers of pollution and threats to America''s natural resources, calling for a nationwide "land conscience" to conserve the nation''s wild places.
