Last night Elizabeth Kolbert, author of the Sixth Extinction, spoke to a packed house in Gannet Auditorium.  She took us through the lives a several sexually confused birds, and warned us of the impact of using fossil fuels and invasive species.  She was funny, relatable, kind and frightening.  I don’t think anyone left the event without a real sense of how our choices are impacting the planet that we leave for our children.
