We hear about sustainability all the time, but what does it mean and why does it matter? At a free public forum at 10:30 a.m. Sunday, April 10, Alan Turnquist, director of sustainability and resilience at Michigan Technological University, will explore some foundational concepts and trends in sustainability and discuss how “sustainability thinking” can alter trajectories at the individual, organizational, community and global levels. It will be an interactive session, available on Zoom, sponsored by the Keweenaw Unitarian Universalist Fellowship. For more information, contact jchadde@mtu.edu.
