Question

Quizplus · Accepted Answer

The suggestion of creating a large canal between the Great Lakes and the southwest is not sustainable because it could deplete water levels in the Great Lakes. The Great Lakes are a vital source of freshwater, and their levels have already been declining due to various factors such as climate change and human activity. Diverting water from the Great Lakes to the southwest could exacerbate this problem and put the ecosystem and local economies at risk.
