Gulf of Mexico

In a New Orleans courtroom this week, BP and the federal government are arguing over how much oil gushed into the Gulf of Mexico after the Deepwater Horizon explosion in 2010.

Oil flowed from the out-of-control well for nearly three months. Just how much oil spilled will be key in determining the amount BP will have to pay in federal fines and penalties.

"Everything down there is dead."

That's one stunning quote from Hawaii News Now's latest report about the devastating damage that's been done to the marine life off Honolulu's Sand Island by 233,000 gallons of molasses that were spilled into Honolulu harbor on Monday.

Since the 1930s, Louisiana has lost roughly as much land as makes up the state of Delaware.

"If you put the state of Delaware between New Orleans and the ocean, we wouldn't need any levees at all," says John Barry, vice president of the Southeast Louisiana Flood Protection Authority-East. "There is this large buffer of land that has disappeared, and that buffer makes New Orleans much more vulnerable to hurricanes."
