Making a Rebuilt New Orleans Sustainable

摘要

The tragic events resulting from Hurricane Katrina have seen a major U.S. city almost totally destroyed, and it is 100 years of human activity that have created the conditions leading to this inevitable tragedy. The dramatic, human-driven deterioration of 25% of the wetlands of the Mississippi delta has removed an important buffer against storms. The river that built and nourished the delta over thousands of years has been leveed to its mouth, preventing the freshwater, silts, and nutrients that nourished and sustained the delta from flowing over the wetlands.
