US President Barack Obama will create the largest marine reserve in the world by expanding the Papahanaumokuakea Marine National Monument off the coast of Hawaii.

The Hawaiian marine sanctuary was created in 2006 by President George W. Bush. It will now quadruple in size, to cover 1.5 million square kilometres of the Pacific Ocean. That's twice the size of Texas. Commercial fishing will also be banned.

 Monumental marine expansion

Around the world, there are more than 6,500 protected areas of seas, oceans or large lakes. Here are the 10 biggest.
