The Great Lakes have faced various threats for years, from industrial pollution to invasive species, but another challenge worries many researchers these days — the emerging chemical threat.
It’s not just pesticides, as scientists are finding worrying levels of pharmaceutically active compounds such as anti-inflammatories, antibiotics, anti-epileptics, and beta blockers in lake water. As well, hormones, pesticides and alkylphenols have been identified as threats.
The warning about pesticides in the lakes is simple and disturbing: "Many pesticides are suspected of being endocrine disruptors which can cause sexual abnormalities and reproductive failure."
In one study, seven great blue heron colonies were sampled in the St. Lawrence River . Samples were analyzed for 21 pesticides. More than half of these 21 pesticides were detected in about 50 per cent of the samples, the study stated.
Mother Nature tries, her best to keep a balance (ECOSYSTEM), that balance has been Compromised--The Rich get Richer, and, The Poor poorer.
The level of pesticides in the lakes, as well as the type of chemical, depends on where the test samples are taken. The Humber River watershed has higher levels of the chemical atrazine than the Don River watershed because it includes more agricultural area.

It is a shame that more people are not aware of the tragic losses our world is facing

Amazing concepts are conveyed with this photograph! It speaks to the upside down ecosystem and Mother Nature trying her best to work with us. Great use of light and selective color.

Great edit, Doug. Creates a meaningful illusion that all is well with the world, that Nature will survive no matter what. Let's hope that is the case.

Great shot & editing! It is heart-breaking to learn what is being done to our Ecosystem:( Maybe this photo will educate more people & get the word out.
