Experts in philosophy, conservation and animal behavior believe dolphins and whales are sufficiently intelligent to justify the same ethical considerations as humans. These experts are calling for support for a “Declaration of Rights for Cetaceans.” Worldview breaks down the arguments with philosopher and ethicist Thomas White, author of In Defense of Dolphins: The New Moral Frontier. Also, the World Music Composers’ Salon features a lecture and performance by a member of Chicago’s world music community, followed by a Q&A session. Worldview's Jerome McDonnell and 848/Radio M host Tony Sarabia chat with the salon’s founder, Andrew Edwards. Plus, Salon-goer Habib Wardak introduces us to the rubab, a lute-like musical instrument originally from Afghanistan.
