Will Harlan, southeast director and senior scientist at the Center for Biological Diversity, will give the talk. This region has more species of freshwater fish, mussels and crayfish in its waterways than anywhere else on earth. The presentation will discuss local biodiversity, global biodiversity and the connections between concurrent extinction and climate crises.

Harlan is the author of the book “Untamed: The Wildest Woman in America and the Fight for Cumberland Island,” which was a New York Times bestseller, winner of the Society of Environmental Journalists’ Rachel Carson Book Award and one of Amazon’s Top 100 Books of 2014. He was editor-in-chief of Blue Ridge Outdoors Magazine for 19 years and continues as a senior editor there.
