A68 iceberg on collision path with South Georgia
If the world's biggest iceberg grounds at South Georgia island, it could devastate local wildlife.

The world's biggest iceberg, known as A68a, is bearing down on the British Overseas Territory of South Georgia.
The Antarctic ice giant is a similar size to the South Atlantic island, and there's a strong possibility the berg could now ground and anchor itself offshore of the wildlife haven.
If that happens, it poses a grave threat to local penguins and seals.
The animals' normal foraging routes could be blocked, preventing them from feeding their young properly.
And it goes without saying that all creatures living on the seafloor would be crushed where A68a touched down - a disturbance that would take a very long time to reverse.
