Geologist to speak in Castine
Blue Hill Heritage Trust will host a speaking event and reception with prominent geologist and conservationist Skip Hobbs on Thursday, July 5, at the Castine Historical Society. The talk begins at 5 p.m. with a reception to follow.
Hobb’s illustrated talk is titled “The Future of Planet Earth: A Changing Biosphere—Humans and Global Stewardship.” Since its creation 4.5 billion years ago, the earth has experienced constant change. Geologic change, however, takes time—usually tens of thousands of years, if not hundreds of thousands or millions of years, according to a news release.
Human civilization has made, and continues to make, profound changes to the earth, both to the benefit and the detriment of mankind and all other inhabitants of earth’s biosphere. Life forms have adapted to geological change through natural evolution, or have become extinct. With the exception of several cataclysmic events, the rate of global change occurring today has not previously occurred in geologic history. What will the future bring? How will Maine be impacted? Hobbs will discuss how the earth’s biosphere is transforming; the importance of sustainability in natural resource extraction; climate change and the human factor; and what we can and must do as responsible citizens to deal with and mitigate these changes.
