On Thursday, March 30 at 6pm ET, author Steve Hawley joins our Life Saves the Planet series to explore the ramifications of the extraordinary dam building boom of the last century that culminated in 800,000 dams worldwide today. In his book CRACKED: The Future of Dams in a Hot, Chaotic World, Hawley examines the effect of these dams on biodiversity loss, heat buildup and aridification of the land. Author and essayist David James Duncan will join Hawley in conversation and Q&A from the audience. Register here to join live!
