Turning the Tide

About This Episode


Louisiana's coastal marshes and wetlands cover 9,000 square miles, stretching 300 miles from east to west, and reaching 30 miles inland. Each year, hurricanes and other natural and man-made forces claim between 20 to 25 square miles of vulnerable coastline. Many believe these numbers constitute a national emergency, one which requires immediate scientific and public consensus to "turn the tide" on the problem.

In the balance lay crucial ecosystems, Gulf seafood and fisheries, North American migratory bird and waterfowl populations, the nation’s energy infrastructure and national security, interior navigation and water transport for American produce and goods, and a unique American culture. Turning the Tide examines viable strategies and innovative engineering techniques to help address Louisiana's coastal erosion crisis. The world's foremost authorities on the subject demystify the complex challenges facing Louisiana's coast and reveal new (and sometimes unconventional) discoveries with the potential to change the course of the coast's future.
