Do animals – other than we humans – have thoughts, feelings? Are their emotions similar to ours? Carl Safina is an ecologist who explores our relationship with the living world—and how it could be better. His recent work, and new book, probes how free-living animals experience life - and takes a serious look at their thoughts, emotions, and experiences. Carl's love of nature has led him to a lifetime of studying the world we live in — a world from which we’ve become increasingly separated. In this episode, Alan Alda and Carl Safina look at communication across the animal kingdom, as they reflect on the other animals in the world - with a firm understanding that a lot of what we are, we actually share with them.
