The Maldives has used the Rio+20 UN Conference on Sustainable Development in Brazil to announce that all 1,192 of its islands will become a marine reserve by 2017.
AFP quotes the President Mohamed Waheed as saying: "I would like to announce today Maldives will become the first country to become a marine reserve."
"It will become the single largest marine reserve in the world. This policy will allow only sustainable and eco-friendly fishing. It will exclude deep-sea, purse-seining and other destructive techniques," he said.

It explains that parts of the Maldives are already UNESCO Biosphere Reserves, including the 75 islands of the Baa Atoll.
"Already, Maldives is a sanctuary for sharks, turtles and many species of fish in the Indian Ocean. Trade in these products is now illegal in the Maldives," Waheed also said, according to Environmental Expert.
