A dock extends out into the Mississippi River in Buras, Louisiana. Engineers, environmentalists, shippers, farmers and the oil and gas industry are all trying to find better solutions to confront new challenges facing the river. Some groups and activists who’ve historically been adversaries are now working together. “We want to live here, so how we do that? We’ve got to compromise. That’s it. If we don’t compromise, none of us will be here,” said Louisiana duck hunter Albertine Kimble.
