美国将扩大太平洋海洋保护区的面积

 

The Pacific Remote Islands Marine National Monument will become the largest network of oceanic protected areas in the world.

 

The memorandum bans commercial fishing, deep-sea mining and other extraction of underwater resources in the area.

 

Environmental campaigners welcomed the move although some critics say President Obama could have done more.

 

"This really is a matter of stewardship³. It's also a matter of generational responsibility," said US Secretary of State John Kerry.

 

"We have a responsibility to make sure... the future has the same ocean to serve it. Not to be abused, but to preserve and utilise."

 

The Pacific Remote Islands Area consists of seven scattered⁴ islands, atolls and reefs that lie between Hawaii and American Samoa.

 

The waters that surround these islands are home to corals, seabirds, sharks and vegetation not found anywhere else in the world.

Area 'pristine⁵'

 

President George W Bush set up the marine preserve in 2009 but until now it only encompassed⁶ an area 50 nautical⁷ miles (92km) from the islands' shores.

 

Now the protected area is being expanded to 200 nautical miles from the unique atolls. It will cover 490,000 sq miles (1.2m sq km) - an area roughly three times the size of California.

 

Mr Obama first signalled his intention to expand the monument in June and asked for comments on the final boundaries from fishermen, lawmakers and scientists. 

 

Environmental groups greeted the announcement and said they hoped it would spur other nations to take similar steps.

 

"The president acted expeditiously⁸, while the area is still largely pristine and undisturbed," said Frances Beinecke, president of the Natural Resources Defense⁹ Council.

 

However, some critics say the expansion falls short of what Mr Obama could have done had he used the full extent of his powers.

 

The islands affected¹⁰ are divided into five regions and the expansion only involves three of them.

 

If Mr Obama had expanded the preserve in all five regions he could have protected more than 780,000 sq miles, some environmentalists say.
