Why we still need shade in an A.C. world

Ancient cities designed shade into their built environments — a lesson present-day builders could learn from. Environmental journalist Sam Bloch joins host Krys Boyd to discuss how, in a world that faces searing temperatures, shade is a natural resource we should all be striving for, why it’s not just trees that can provide it, and why air conditioning has made us lose connection with the outside world. His book is “Shade: The Promise of a Forgotten Natural Resource.”
