US President Barack Obama has
expanded a national monument off Hawaii, creating the world's largest
marine reserve, the White House says.

"By expanding the monument, President Obama has increased protections for one of the most biologically and culturally significant places on the planet," said Joshua Reichert, an executive vice president at the Pew Charitable Trusts.
Greenpeace also hailed what it called a "bold decision" that will ban commercial fishing and mineral extraction in the region.
"We are disappointed that the president has made a decision to close an area nearly the size of the entire state of Alaska without public process," Sean Martin, the president of the Hawaii Longline Association told the Associated Press news agency.
"This action will forever prohibit American fishermen from accessing those American waters. Quite a legacy indeed," he added.
