Losing Louisiana: Life in the Disappearing Mississippi Delta
Al Jazeera (2019)
This documentary concerns the steady disappearance of the Mississippi delta region in Louisiana. The erosion stems partly from climate change and rising sea levels, partly from channels petroleum corporations have dug through the wetlands and partly from decades of diverting new Mississippi sediment out to sea.
The gradual disappearance of the delta has means many coastal residents have lost their livelihood. Due to salt water contamination of their ground water, farmers are no longer able to grow sugarcane and rice or graze stock. Meanwhile shrimping industry has collapsed. Because shrimp require require freshwater marshes to reproduce, their populations have been have been decimated.
In this remake of their 2009 documentary, Al Jazeera filmmakers revisit an area of the Mississippi delta they first filmed ten years ago. They learn the rate of delta shrinkage has declined from 70 to 15 square miles per year. Subsidence is worst in poor communicates which have no real protection against hurricanes. This contrasts with well-to-do communities, which have built massive hurricane levees.
For some reason the 2019 segment makes no mention of the 2010 Deep Water Horizons disaster and the toxic effect on wildlife of the massive oil spill and the poisonous oil dispersant Corexit BP dumped into the Gulf of Mexico.
Here are 2013 and 2016 accounts summarizing the long term effects on Gulf marine life that will take decades to repair:
