Please Explain: Invasive Species

Growing global trade means more bugs and plants end up where they don’t belong, causing widespread environmental damage. On today’s Please Explain, we’ll learn how invasive species—from Asian purple loosestrife to the Colorado potato beetle—can wreak havoc when they’re accidentally imported to a new environment. We’re joined by Robert F. C. Naczi, Curator of North American Botany at the New York Botanical Garden; Jessica Arcate Schuler, Manager of the Forest, at the New York Botanical Garden; and Thomas M.Grothues, assistant research professor at Rutgers University.
