The world's largest iceberg has broken,

and is moving towards the Southern Ocean.

Giving this information on Friday,

scientists said that it has happened after more than 30 years,

that the world's largest iceberg is slipping.

A23a is also one of the oldest icebergs in the world.

It is also possible that A23a may be destroyed on South Georgia Island.

It also threatens to cause problems for thousands of seals,

penguins and sea birds living  Antarctica.

Experts say that despite the heat an iceberg of this scale,

has the ability to survive for a long time in the Southern Ocean.
