We are living in a time of unprecedented and rapid technological, economic, social, and environmental change. I will argue that, in spite of what seems to be ever greater technological complexity, the largest scale natural “operations” of Earth are actually undergoing an unnoticed simplification, one that is already affecting geological landscapes, biodiversity, global economy, and human population. I will make predictions about specific “simplifications” that will accrue from sea-level rise, climate instability, diminishing petroleum output, increasing population, and dwindling global food supply. Whether these simplifications happen fast enough to allay an actual mass extinction (of our species) rather than “just” the current and expanding “mass depletion” over the next century, remains to be observed.
Dr. Peter Ward is a paleontologist and astrobiologist at the University of Washington and a world-renowned authority on mass extinctions, climate change, evolution, and astrobiology. His research examines the history of life on Earth over billions of years, focusing in particular on mass extinction events. That work gives him unique ‘deep time’ perspectives on the future of life on this planet, as well as the possibility of life elsewhere in the universe. Dr. Ward has appeared on NOVA and Ted Talks and written over a dozen popular science books including “Rivers in Time: the Search for Clues to Earth’s Mass Extinctions” and “The Flooded Earth: Our Future In a World Without Ice Caps”.
Saturday, Dec 7th at 4 pm; First Baptist Church, 1202 Lawrence St., in uptown PT. The lecture is free and open to the public; a $5 donation per person to defray expenses would be much appreciated. This event is sponsored by Quimper Geological Society, an Earth Science outreach group of Jefferson Land Trust.
