SCIENCE/POLITICS/NATURE A D Advance praise for Restoring Colorado River Ecosystems L E R “Like a skilled surgeon,Adler opens up the Colorado River to show what we have done to make it bleed and what it will take to restore some measure ofecological health.Without bluster or sentimen- R tality,he explains just how challenging the job is,and he pulls no punches describing the technical, E political,economic,and legal obstacles that lie in the way.” S —Joseph L.Sax,professor,University ofCalifornia,Berkeley,author ofMountains Without Handrails T O “Robert Adler has the rare gift ofwriting with great clarity about topics ofgreat complexity. R Readers ofthe book will emerge as more realistic and pragmatic advocates for the well-being of I N human and natural communities,sharper and wiser thinkers,and better citizens.This book is a major contribution to the improvement ofpublic discussion and understanding ofthis century’s G environmental circumstances.” C —Patty Limerick,faculty director and board chair ofthe Center ofthe American West,University O ofColorado,author ofThe Legacy ofConquest L O “In Restoring Colorado River Ecosystems,Robert Adler has brought his orderly mind to bear on the R vast complexities ofthe Colorado River.He asks,‘What are we willing to give back in order to A recover what has been lost?’He answers with bold and reasoned judgments to pack in our river D bags as we make our way downstream.” O —Stephen Trimble,author ofLasting Light: 125 Years ofGrand Canyon Photography R I “RobertAdler briskly takes us through the natural,human,and legal history ofthe Colorado River V to build a convincing case that damage to animals,fish,plants,and aesthetics can be reversed. E R Rethinking how we use water and produce electrical power may be even harder than tearing down dams orrebuilding stretches ofriver channel.” E C —David Getches,dean and Raphael J.Moses Professor ofNatural Resources Law,University of O Colorado Law School S Y S Robert W.Adleris associate dean for academic affairs,and James I.Farr Chair and Professor of T Lawat the S.J.Quinney College ofLaw,University ofUtah.
