Maine’s coastal and island communities have relied on natural resource harvesting for centuries, but climate change and other factors including ocean acidification could remake the local economy. It’s not only some species of fish that are endangered; the vitality and authenticity of island and coastal communities are at risk.

These dynamics will be explained and explored Wednesday, July 20, from 7 to 8 p.m. in a wide-ranging discussion that includes short films produced by the Island Institute. The talk will be held at the Camden Yacht Club, located on Bay View Street.

Tom Groening is the editor of the Island Institute’s annual publication, Island Journal, and the 10-times a year newspaper The Working Waterfront (circulation 50,000). Previously, Groening was a reporter and editor for the Bangor Daily News and the (Belfast) Republican Journal. He lives in Belfast.

Island Institute President Rob Snyder will be joining Groening.

The talk is free of charge and open to the public. Donations at the door will be gratefully accepted to benefit the non-profit Camden Area Youth Seamanship Program (CAYSP). For more information please contact the CYC office at 236-7033 or visit camdenyachtclub.org.
