Study Notices Lakes Erie, Ontario as Most Threatened among All
Lakes Erie, Ontario most threatened, finds a new analysis of 34 stressors to the world's largest supply of fresh water.
In their recent findings, the authors of the study have clearly mentioned that Lakes Erie and Ontario are the most threatened ones among the five Great Lakes as they are facing multiple threats starting from zebra mussels to toxins fear to light pollution from brightly lit shoreline cities etc. The depths of Lake Superior were noticed to be the most pristine among all.
They claimed that due to so many running threats at same time, it has become difficult for the officials to apply the restoration efforts more strategically.
"It's almost a death-by-a-thousand-cuts syndrome," said Mr. Peter McIntyre, a coauthor of the study and a professor at the University of Wisconsin-Madison's Center for Limnology.
The biggest threat claimed by the authors is the invasive mussels and lamprey, which they fear, is a big threat for the food chain. Next is the climate change, which they fear, will affect the water temperature and water levels too. Third is the ballast water that is released from ships because they can get into more of uninvited species to the water there. Fourth, more urbanization along the coast is sweeping auto and human waste into the waters during rainfall, which is again a big threat for them.
"There are many environmental stressors that affect an ecosystem, and the Great Lakes is a poster child for that", he said.
