Ever wonder what's going through your dog or cat's mind? What about a bird or an elephant? Today's guest, Carl Safina, has not only wondered about it, he's devoted his life to exploring man's relationship with nature and how 'non-human' animals think and feel. We forget that we are animals, too, and minimize the ability of animals to have sophisticated inner lives, form relationships and have emotions. Mr. Safina, author of the new book, Beyond Words: What Animals Think and Feel, explains how and why animals are being threatened more by man today than ever before, and what this means for them - and us.
