 are going to have to pay money to do some restoration along the river. And the way they're doing that is through mitigation banking, which is where a private company that does restoration comes in, restores a whole site, and then the companies that have polluted the river over time pay them to buy credits. So essentially, the habitat's already there because the company has done the restoration, and then groups that polluted the river pay them, and they get their money back that way.
