The Great Lakes: Navigating Environmental Threats from Past to Future

The Great Lakes, a cornerstone of North America's historical and geographical tapestry, have witnessed a paradigm shift from exploration and settlement led by European pioneers like Samuel de Champlain and Louis Jolliet, to industrialization and urbanization. However, the progress came with a cost. Lake Erie, in the late 1960s, was virtually transformed into a 'dead lake' due to the heavy pollution from industrial and residential discharges.

The Phoenix Rises

Legislation such as the Clean Water Act breathed life back into Lake Erie, championing its restoration. A landmark development was the Great Lakes Compact, established to staunch water diversion, which marked its 15th anniversary in December. This Compact was born out of a Canadian company's attempt to export Lake Superior water to Asia, and it now mandates unanimous approval from all eight states and the Ontario province for any water diversion waivers.

The Challenges of 2024

The Great Lakes face a new array of threats in 2024. Invasive species like zebra and quagga mussels threaten to upset the ecosystem balance by tampering with the food chain. The looming menace of Asian carp entering the Great Lakes system could wreak further havoc on the already vulnerable ecology. Another pressing issue is plastic production and pollution, with microplastics in waterways becoming an increasing concern.

Controversies and Environmental Hazards

The controversial oil pipeline, Line 5, raises the specter of potentially catastrophic oil spills in the region. Plans for a Canadian Nuclear Waste Repository near Lake Huron have also sparked environmental safety apprehensions. The receding ice cover on the Great Lakes due to climate change is another cause for concern, as it can spawn more extreme weather events and detrimentally impact the region's wildlife and fishing industry.

On the positive side, efforts are being made to mitigate these threats. The Sustain Our Great Lakes program, in partnership with the National Fish and Wildlife Foundation, is soliciting proposals to benefit fish, wildlife habitat, and water quality in the Great Lakes basin. It plans to award up to $10.6 million in grants in 2024 to improve and enhance stream and riparian habitat, green stormwater infrastructure, and invasive species control. Threats posed by harmful cyanobacterial blooms (HABs) and toxic microplastics are also being studied with a view to devise effective management strategies. And, the construction of the Brandon Road Lock and Dam, authorized by Gov. JB Pritzker, is seen as a crucial initiative to address the threat of Asian carp.

In conclusion, the Great Lakes have endured centuries of change, from exploration and settlement to pollution and restoration. Now, as they face a new array of threats, it is incumbent on us to protect and preserve these precious resources for future generations.
