Wetlands are something of a canary in the mine shaft. The wetlands are able to produce the kinds of water species, the kinds of growing species—flora and fauna—that are important to restore the shoreline and also to restore and replenish the birds, to restore and replenish the animals, to restore and replenish the growing fauna. All of this is extremely important for a good and balanced system. If it doesn't have the balance, the problem can be exacerbated and gets out of whack. When that happens, it presents problems and shows a problem in the entire watershed.
It doesn't affect just the edge of the water. It doesn't affect even just the water. It affects the basin that comes and feeds it entirely, and the basin is very huge. The Great Lakes Basin is bigger than all of Europe put together, so it's a pretty substantial basin.
