This week's calls to action include the following events and activities. (All are free and open to the public, unless otherwise noted.)
The Finger Lakes Institute at Hobart and William Smith Colleges will host a discussion on blue-green algae from 4:30 p.m. to 8 p.m. on Thursday, August 21. The alga was the cause of the water ban that impacted people in Ohio and Michigan. Similar types of toxins have been found in samples in Honeoye and Owasco lakes in recent years. The presentation is intended to help the public and municipal officials differentiate among algae and harmful algal blooms. Registration at www.hws.edu. Cost is $25 for the general public and $20 for students. The event includes a tour of the institute at 601 South Main Street, Geneva, and a picnic buffet.
