BBC News: Australia to create world's largest marine reserve
Australia says it will create the world’s largest network of marine parks ahead of the Rio+20 summit.
The reserves will cover 3.1 million sq km of ocean, including the Coral Sea.
Restrictions will be placed on fishing and oil and gas exploration in the protected zone covering more than a third of Australia’s waters.
Environment Minister Tony Burke, who made the announcement, will attend the earth summit in Brazil next week with Prime Minister Julia Gillard.
