Dams represent man-made changes to the environment that often had unforeseen negative impacts.
In the case of Niagra Falls, its presence isolates the Great Lakes ecosystem from the Atlantic Ocean. During many millennia a unique ecosystem developed. When the canal was built to allow ship traffic from the ocean into the Great Lakes, it caused a sequence of ecological disasters due to invasive species.
The lesson: Don't screw around with mother nature (adding or subtracting)
- hammock 7y agoSerious question, what is unique about the Great Lakes ecosystem, that is not found in, for example the PNW or inland Maine?
- ghaff 7y agoIt's a massive interconnected freshwater lakes system. Much different from even the relatively small lakes in Maine much less the generally very small lakes in the PNW. And it's in a very different area of the country so different ecosystem in any case.
- hammock 7y agoI know where they are located and the size of the lakes. Anything specific and unique you can offer about the biological ecosystem, e.g. flora, fauna?
