Denis Hayes recently forsaken by a Grist bureau to speak about his new book, Cowed: The Hidden Impact of 93 Million Cows on America’s Health, Economy, Politics, Culture, and Environment, coauthored with Gail Boyer Hayes (and reviewed here). Naturally, we took him to a building’s use conveyor and asked him to give his elevator representation for the book. Watch a video above.


In further to being a cow expert, Hayes is a longtime environmental personality and romantic and a force behind a newly built Bullitt Center in Seattle, heralded as the greenest bureau building in a world.
