Israeli politicians are floating an idea to expand their seaside country — artificial islands.

The Cabinet voted on Sunday to explore options for creating artificial islands to make room for infrastructure like water treatment plants, power plants and an airport.

Most of Israel's eight million people live in a narrow strip along the Mediterranean coast, and the country is running out of space there. Most Israelis stay in apartment buildings, and even cemeteries are beginning to bury the dead in multi-level structures.

Prime Minister Benjamin Netanyahu says manmade islands could bolster Israel's economy, ensure its security and protect what little open space remains in the centre of the country.
