Located in the Indian Ocean, the 1,200 islands of the Maldives are famous for their crystal clear waters and pristine white sandy beaches. Yet this stunning archipelago risks being submerged by rising sea levels.

The archipelago also faces another major problem: plastic pollution, which ends up on beaches and in the ocean, destroying the marine ecosystem. Our regional correspondents report.
