Southeastern Louisiana's disappearing wetlands have a broad impact ranging from cultural to economic. Commercial fishing in Louisiana accounts for more than 300 million dollars of the state's economy. More than 70% of that amount stems from species such as shrimp, oysters and blue crabs that count on the coastal wetlands as a nursery for their ...

A diagram of the typical drivers of ecosystem collapse. [1]While collapse events can occur naturally with disturbances to an ecosystem—through fires, landslides, flooding, severe weather events, disease, or species invasion—there has been a noticeable increase in human-caused disturbances over the past fifty years.
A fishery which rotates among multiple species can deplete individual stocks and still be sustainable so long as the ecosystem retains its intrinsic integrity. [8] Such a definition might consider as sustainable fishing practices that lead to the reduction and possible extinction of some species. [2]

Failure to account for the role of older fish may help explain recent collapses of some major US West Coast fisheries. Recovery of some stocks is expected to take decades. One way to prevent such collapses is to establish marine reserves, where fishing is not allowed and fish populations age naturally. [17]
Under the highest-emission scenario, many countries would see substantial reductions in seafood available from exclusive economic zones by 2050. [1]Fisheries are affected by climate change in many ways: marine aquatic ecosystems are being affected by rising ocean temperatures, [2] ocean acidification [3] and ocean deoxygenation, while freshwater ecosystems are being impacted by changes in ...
The unfolding crisis in Louisiana has raised doubts more broadly about whether people can remain in America’s most disaster-prone areas amid increased storms, floods, heat waves, fires and droughts.
