In 1932, Louisiana's coastal wetlands extended far into what is now open water.

Land that existed in 1932 is represented in blue.

Human activities began reshaping the coast. Oil extraction disrupted the ecosystem. Levees starved wetlands of sediment.

The effects of climate change are compounding existing problems.

Oil wells once on solid ground now sit in open water. Louisiana has lost over 1,900 square miles of land since the 1930s.

A new analysis from The Times-Picayune has found more than 3,600 wells that were drilled on land that are now below the water's surface.

The areas in red show places where oil wells have likely become submerged.

As sea levels rise, thousands of wells will fall below the waterline.
