In this episode, Amy and Nate explored how and why conserving water also saves energy (and reduces greenhouse gas emissions as a result). We had a great interview and site visit with Mike Evans at the Class of 1966 Environmental Center at Williams College to talk about water conservation and especially the composting toilets in the building. Parents, be warned - we do talk about poop. (You can imagine how excited Nate was about that.) . While we do tell some jokes, none of them involve poop.
