“It’s no secret that the Great Lakes are suffering tremendous ecological strain — Lake Erie was even pronounced “dead” for a time during the 1960s because of an overload of phosphorus from municipal waste. Back in 1615, though, when the entire region was pristine and explorers Samuel de Champlain and Étienne Brûlé gazed out together from Lake Huron’s shores, they dubbed it la mer douce, ‘the sweet sea.’ Today roughly one-quarter of Canada’s population and a 10th of America’s population drink from the Great Lakes basin; the beleaguered lakes alone hold more than a fifth of Earth’s freshwater.”
Questions to Ponder: What watershed do you live in? Where does your drinking water come from? When you flush the toilet, where does it go? How are places in your watershed linked? How does this similar map shed more light on these issues?
