Sarah Mack pilots her 24-foot boat to the edge of a grassy salt marsh in southern Louisiana to bring a slow-moving, $90 billion crisis to life.
Tierra Resources, a wetland restoration company, planted plastic poles at the edge of the marsh more than a year ago. Today, those poles stand alone in the water — at least 6 feet from the shore.
“And this is a more protected site,” says Mack, who started Tierra Resources after Hurricane Katrina ravaged New Orleans. “This is not bad erosion.”
