A Whole New World

On today’s Leonard Lopate show: we’ll look into the militarization of foreign assistance and nation-building. Then, Joyce Carol Oates talks about her memoir, A Widow’s Story. Also, Brian Bedford discusses what it's like to direct and star in an acclaimed new production of Oscar Wilde’s “The Importance of Being Earnest.” Plus, humans have changed the planet so much that some have suggested we’ve created an entirely new geologic epoch, the “Anthropocene.” Elizabeth Kolbert explains what that means.
