Going "Beyond Words" To Find Animal Feelings
We've come a long way from the days when we described the other creatures on the Earth simply as "beasts" or "dumb animals."
We certainly understand animal behavior better over time. But do we understand it well enough to have an idea of what animals think and feel?
Carl Safina is trying. Safina is an ecologist and the host of the PBS series "Saving the Ocean."
He studied wolves, killer whales, and elephants up close, and writes about his findings in Beyond Words: What Animals Think and Feel.
He joins us with the insights he gained into animal hearts and minds.
