Earlier this year, a titanium mine was slated for construction on the edge of Georgia’s Okefenokee Swamp, an unusually diverse ecosystem that is home to some of the country’s most pristine wetlands. If built, the mine would likely have unleashed catastrophic pollution in the area.  Then in June, the project was called off. In a stunning deal, the company behind the mine announced it had reached a $60 million agreement to sell the site of the proposed project to a group of conservationists.
