On Friday, May 19, This House of Books in downtown Billings will host a reading by Billings author Steven D. Paulson. Starting at 5:30 pm, Paulson will read from and discuss his book Environmentalists: An Eyewitness Account from the Heart of America. A 25-year staffer at the Northern Plains Resource Council, Paulson introduces readers to a score of individuals who became involved in protecting the environment, and their reasons for doing so. He analyzes issues and recounts his own experiences, both as an activist and simply as someone who cares about our natural and human environment. Snacks will be available at the event.
