Defining what is a “native” species and what is not is more controversial than many people think. An unusual New York Times op-doc called “Hi! I’m a Nutria” examines the question. A few choice lines: “When do we get to draw a line on who’s a native? 10 years? 100 years? 30,000 years?” And “I’m here now. You’re here now. Let’s just be friends!” The video cannot be imbedded, so follow the link above.
