Mark Tercek stands tall in environmental action. He was president and CEO of The Nature Conservancy for 11 years. From Wikipedia: "Founded in 1951, The Nature Conservancy has over one million members, and has protected more than 119,000,000 acres of land and thousands of miles of rivers worldwide. The largest environmental nonprofit by assets and revenue in the Americas, The Nature Conservancy ranks as one of the most trusted national organizations in Harris Interactive polls every year since 2005. Forbes magazine rated The Nature Conservancy's fundraising efficiency at 88 percent in its 2005 survey of the largest U.S. charities. The Conservancy received a three-star rating from Charity Navigator in 2016 (three-star in 2015)." Before then he was a partner at Goldman Sachs. Curious how someone goes from investment banking with Hank Paulson to the Nature Conservancy? He describes that calling. We also enjoy that we both are reaching new audiences---I share about Magamedia and he about talking about global warming in Alabama. As much as the content he shared, I loved his emotion of, as I read it, enthusiasm and expectation of success, knowing the challenges and the likelihood of catastrophe, whatever progress he makes.
