Life on Earth is perilous. All its flora and fauna, including humans, are minute compared to the planet’s epic forces. Several times in Earth’s history, plate tectonics, ice ages, massive meteorite impacts, and more have wiped out species, even entire families and genera. Dan Northcut, a favorite NTMN curriculum instructor, will present on previous mass extinctions and explore the similarities to our present circumstances, with its unprecedented loss of biodiversity and rate of species extinctions. Are dire changes to food security, air and water quality, human health, and ecology in store? Tune in for a tremendous conclusion to our Survivor speaker theme for 2021!


A native Texan, Dan Northcut has been teaching earth and environmental sciences at his high school alma mater, St. Mark’s School of Texas, since 1987, and is presently the Director of Environmental Studies and teaches AP Environmental Science and earth science. He studied geology at The Colorado College, receiving a bachelor’s degree, and went on to earn his master’s degree at University of Texas at Dallas. When not at work, he’s out learning, exploring, and experiencing the natural world. He certified as a Texas Master Naturalist in 2000 and later served as president of the North Texas chapter. He’s taught several topics for the North Texas Master Naturalist certification classes for the past 20 years.
