A potential threat to entire wildlife ecosystem including penguins, seals and krill has been seen as the World's biggest mass of ice 'A68a iceburg' is heading towards South Atlantic for a collision with South Georgia. In July 2017, world's largest iceberg, A68a broke off from Antarctica's Larsen C Ice Shelf.
The iceburg is currently travelling through open waters but is just a few hundred kilometers away from the British Overseas Territory of South Georgia. The travelling speed is around 1 kilometer per hour, within 3 or 4 weeks at this current recorded speed, iceberg could reach the British Overseas Territory. Environmental Scientists fear that the large mass of ice of 4,700 square kilometer (1,815 square mile) could make severe repercussions on the island's wildlife population for years to come.

Professor Geraint Tarling, Senior Biological Oceanographer at the British Antarctic Survey (BAS), said the iceberg could prevent seals and penguins from leading their normal feeding grounds at a time of year that is crucial for the colonies' growth. They may affect the young ones life as the parent wont be able to get back on time particularly for feeding. When the iceberg moves close to the shore, the diverse marine life might be destroyed that plays a critical role in balancing the global climate. An approximate of 5 million seals of four different species lives in South Georgia and the neighboring South Sandwich Islands (SGSSI).
