VOTE NO on H.J. Res. 140—which would greenlight a sulfide-ore copper mine in the headwaters of the Boundary Waters. Sulfide-ore copper mining is one of the most polluting activities humans have ever come up with. There’s never been a copper sulfide mine anywhere on Earth that hasn’t caused pollution. And this particular mine, because it’s near so much water, would with a 100% certainty produce sulfuric acid. Just to be clear: that’s battery acid. The copper would go to China for processing, the profits go to Chile. American taxpayers would be left with the bill to clean it up, which would take literally centuries. It would destroy the pristine waters of the Boundary Waters—which hold 20% of all freshwater in the entire Forest Service system—for centuries. It would flow all the way down to and through Voyageurs National Park. This issue is as black-and-white as it possibly gets. This is the most consequential public lands fight of the year so far. And it couldn't be any more urgent. Protect the Boundary Waters. Reject H.J. Res. 140
