Check out this Interactive Graphic from Dan Swenson and the Times-Picayune describing how Louisiana was formed over 7,000 years and how human actions from the 1930s onward are fast reversing the process.

The land loss video below is based on USGS National Wetlands Research Center data and the coastal land loss map shows predicted land loss from 1932 until 2050. The America's WETLAND campaign would like to thank the CWPPRA website for providing the following products.
