The United States joined forces with other nations Tuesday to declare a vast swath of the Pacific Ocean a marine sanctuary and take "historic" steps to combat illegal fishing, AFP reports.
Taking the helm in a stepped up fight to save the planet's oceans, President Barack Obama ordered his administration to chart a way to expand an existing US reserve and create what would be the world's largest marine park.
And a two-day conference hosted by the State Department was given a sprinkle of stardust by Hollywood A-lister Leonardo DiCaprio, who pledged $7 million from his foundation to help clean up the seas.
The US is planning to expand the Pacific Remote Islands National Monument, which together with action taken by other nations such as the Cook Islands and Kiribati, would mean some three million square kilometers (1.2 million square miles) are declared off-limits to all fishing fleets and drilling activities.
A total of $1.8 billion -- with a $1 billion alone coming from Norway to combat climate change -- was pledged at the conference seeking to draw up an action plan to fight pollution, acidification and overfishing.
"Right now only a small fraction of the world's ocean... is currently protected," US Secretary of State John Kerry said.
More must be done but the new commitments are "a terrific start," he said, after leaders from more than 80 countries met for two days with scientists and industry experts.
Obama said he would use his executive powers to expand the Pacific Islands marine park, where the White House said "tropical coral reefs and associated marine ecosystems are among the most vulnerable areas to the impacts of climate change and ocean acidification."
In a video address, Obama said he had also directed the US government to "build a national strategy to combat black-market fishing."
"Rising levels of carbon dioxide are causing our oceans to acidify. Pollution endangers marine life. Overfishing threatens whole species as well as the people who depend on them for food and their livelihoods," Obama said.
But the White House pledged that fishermen, scientists and conservation experts would be consulted before the outlines of the marine sanctuary are defined.
Bleached coral
The plan could ignite a new battle with Republicans in Congress, angered by Obama again using his executive powers to bypass the US legislature.
"If we ignore these problems, if we drain our oceans of the resources, we won't just be squandering one of the humanity's greatest treasures, we'll be cutting off one of the world's major sources of food and economic growth," Obama warned.
He won support from Hollywood actor DiCaprio, an avid diver, who said his love for the oceans had led him to explore underwater worlds and delight in all kinds of marine life.
"I've witnessed environmental devastation first hand," DiCaprio said, recalling two dives he made some 18 years apart at the coral reef in Australia.
"What once had looked like an endless underwater utopia is now riddled with bleached coral reefs and massive dead zones."
"Unfortunately today, there's no proper law enforcement capacity and little accountability for violating the law. It's the Wild West on the high seas," warned the star of the box-office hit movie "Titanic."
Kerry said the move to clamp down on illegal fishing meant all seafood sold in the United States would be "sustainable and traceable."
A recent report found that between 20 percent and 32 percent of wild-caught seafood imported into the US in 2011 came from illegal or "pirate" fishing.
Environmentalists also welcomed Obama's plans as "a historic step forward in the fight against seafood fraud and illegal fishing worldwide."
"This initiative is a practical solution to an ugly problem and will forever change the way we think about our seafood," said Beth Lowell, campaign director with the international advocacy Oceana group.
