Doug Tallamy is a professor of Entomology and Wildlife Ecology at the University of Delaware, where he studies the many ways insects interact with plants and how such interactions determine the diversity of animal communities. In his book Bringing Nature Home, Tallamy explains why everyone with access to a patch of earth can make a significant contribution toward sustaining biodiversity by simply choosing native plants. This episode- pulled from an interview conducted during the production of the film Negotiating with Nature - expands upon these ideas and alarming facts.
