Monarch butterflies are a scientifically unique, economically valuable, and culturally significant species. But monarchs are now under threat from climate change, habitat loss, pesticides and other factors. In recent weeks the International Union for the Conservation of Nature officially declared the monarch butterfly an endangered species.
Today, we explore why monarch butterflies are important, how they became endangered, and what we can do to save them. With special guest Dr. Karen Oberhauser, Director of the University of Madison-Wisconsin Arboretum.
