WhadayaKnow? What is the greatest pollutant in the Great Lakes?
By Marty Deskovich and Marites Woodbury
Every Monday Great Lakes Echo runs video clips of random people answering questions that experts believe environmentally literate citizens should understand. In the last clip an expert explains the correct answers.
This week’s question is “What is the greatest pollutant in the Great Lakes?”
This week’s expert is Jon Bartholic, director of the Institute of Water Research at Michigan State University in East Lansing, Mich.
He is also a professor in the departments of Community, Agriculture, Recreation and Resource Studies and Crop and Soil Sciences at MSU.
I have no speakers to hear his comments. My vote is on invasive species are the greatest pollutant in the Great lakes.

Why pick one? We should all make ourselves familiar with the top ten and do something about them.

However, the greatest all time threat to the Lower Great Lakes is by far the interruption, discontinuance, inhibition,stopping or otherwise interfering with the normal, regular ice flow from Lake Erie into Lake Ontario. This is a thousands of years old process that did so much good for so many, if not all, of the inter-connected ecosystems within that portion of the watershed. So while pollution is a definite threat (chemical) so is the loss of a kinetic energy. On top of that there is the change in thermal energy that Lake Erie received. I invite you to check out my site about this crime against nature and join me in exposing the harm done to our 2 little Great Lakes. go to http://www.bantheboom.com for more info. thanks, Joe Barrett

Sorry Jim…that wasn’t meant to be a dislike on your post. Touch screen on phone doesn’t always do what I want. You made a very good comment!

Agricultural runoff and sewage overflows are the biggest two.
