“The Sixth Mass Extinction,” Tom Krohn, June 17, Baxter County Library, 1 p.m.-3 p.m.
June 17, 2017 @ 1:00 pm - 3:00 pm
There have been five mass extinctions in the last 500 million years–the last one being the K-T extinction 65 million years ago that wiped out the dinosaurs. Most biologists think we are in the midst of the sixth mass extinction that could wipe out over half of all existing plant and animal species by 2100.
Join Tom Krohn at Baxter County Regional Library as he discusses what caused the first five mass extinctions, what is causing the current one and why we should be concerned.
