Thomas M. Kostigen is The New York Times bestselling coauthor of The Green Book: The Everyday Guide to Saving the Planet One Simple Step at a Time, and a veteran journalist.
He's traveled the world—from the deserts of the Middle East to the slums of India; from polluted cities in China to the jungles of Borneo; from the Arctic Circle to the Amazon; as well as many other environmental hot spots—to investigate the effect of man on the planet.
His new book, You Are Here: The Surprising Link Between What We Do and What That Does to the Planet (HarperOne), will be published this September.
