If Davy Crockett was the “king of the wild frontier”, his descendant David
Crockett, a councillor in Chattanooga, is the king of sustainability in
America’s new urban landscapes. The story of how he greened his rust-belt

Lerner’s nicely turned Eco-Pioneers. Published by MIT Press, $25, ISBN
0262122073.
