EVENT: Aquatic Biologist to Lead Talk on Deteriorating State of Great Lakes
What: Presentation by Dr. Julie Wolin, Aquatic Biologist, CSU
When: Wednesday, July 25 from 7 - 8:30 p.m.
Where: Fairmount Presbyterian Church, 2757Fairmount Blvd., Cleveland Heights., Ohio
Dr. Wolin, an acquatic biologist from Cleveland State University, will lead a discussion of the deteriorating state of the Great Lakes, pointing out that Lake Erie, in particular, is suffering from the problem of too many nutrients, primarily in the form of phosphorous and nitrates.
The phosphorous comes from both agriculture and industrial sources. Too much phosphorous changes the ecosystem, and, working in concert with invasive species, leads to an overabundance of “green algae” blooms. The algae, in turn, have helped to produce the “Lake Erie Dead Zone,” which is devoid of enough oxygen to support the fish population.
Humans are contributing to this problem through the use of lawn fertilizers and run-off from application of nutrients to agricultural fields. Dr.Wolin will discuss measures that humans can take to head off this possible “tipping point’ in the Lake Erie ecosystem, including: the use of phosphorous free fertilizer, avoiding fertilizer applications within 25 feet of any body of water and keeping water on one’s property by installing rain gardens or rain barrels.

Talk of natural climate solutions typically conjures up images of lush forests or pristine wetlands. But in King County, Washington, one important natural solution comes from a less Instagram-worthy source: the toilets of Seattle.
Weight loss aside, there is no shortage of benefits to eating healthier: a lower risk of heart disease and cancer, reduced gut inflammation and preventing memory loss later in life, to name a few. A healthy diet may also reduce hearing loss later in life, according to a new study out of Brigham and Women's Hospital.
