Part of Lake Forest Open Lands' Three-Lecture Series, Great Lakes, Great Issues. Following the film, Toxic Puzzle, Dr. Bullerjahn, Director of the NIH/NSF Lake Erie Center for Fresh Waters and Human Health will discuss toxic nutrient pollution which pose threats to fresh water resources all over the world. This has yielded harmful algae blooms affecting drinking water for tens of millions of people. Prevention and mitigation of these bloom events require an understanding of the environmental conditions. This film and presentation will cover a range of topics ranging from algal physiology to land use management, and how these studies can inform public policy aimed at protecting the public from these threats.
