Louisiana’s Delta is a veritable bounty of rich estuarine life, supporting a robust commercial fishing industry, fertile oil fields, millions of migrating waterfowl, and at the heart of it all, the mighty Mississippi — a navigation channel that allows the passage of goods worldwide. It is not an overstatement to say that it is the cradle of the U.S. economy. For this reason, the erosion of Louisiana’s wetlands is one of the greatest environmental threats the United States faces today. Every hour a chunk the size of a football field is lost. Each year 25 square miles of land is gone forever, and without a mitigation strategy, the marine economy, the oil and gas industry, and even the citizens of New Orleans will be seeking refuge elsewhere in 30 years or so.
