The U.S. lost an average of 80,000 acres of coastal wetlands from 2004 to 2009, according to the latest data published by federal agencies. More than 70 percent of the estimated loss came in the Gulf of Mexico; nationwide, most of the loss was blamed on development that incurred on freshwater wetlands.
"The losses of these vital wetlands were 25 percent greater than during the previous six years," NPR's Elizabeth Shogren reports for our Newscast unit. She also notes that the loss equals "about seven football fields every hour."

The idea that grass can armor anything is hard to believe.
But on a recent visit to the Lake Pontchartrain levee, LSU agronomist Jeff Beasley explained how plain old, garden variety grass has earned a reputation with the US Army Corps of Engineers as one of the best armoring materials to keep the huge mud walls of a levee from collapsing during a storm.
"You know how we reinforce concrete with rebar?" says Beasley. "We can do the same with these levees."
New Orleans' levee board is suing energy companies for damaging the Mississippi River delta by cutting canals through the marshland. The canals let in sea water, which kills marshes, eroding the city's protective buffer against storms. A map of the delta.

When Louisiana officials unveiled the $50-billion Master Plan for the Coast, a 50-year program that could prevent most of southeast Louisiana from sinking under the Gulf by the end of the century as predicted, they knew one of their most important priorities would be getting reliable, long-term funding through Congress.

According to federal regulations, Louisiana’s nine-day recreational red snapper fishing season legally starts next weekend. But some fishermen have been landing snapper since the state season started in March — at the risk of also landing a ticket from federal authorities.
The discrepancy between state and federal red snapper authorities is the subject of a bill sponsored by Sen. Bret Allain. Allain wants to put an all-out ban on red snapper, reasoning that if the fisheries are in such dire straits, maybe they shouldn’t be fished at all.
