World’s largest iceberg on collision course with South Atlantic island

Iceberg A68A is moving towards South Georgia in the South Atlantic, posing a threat to local wildlife if it grounds nearby. The iceberg, similar in size to Delaware, could take a decade to melt, disrupting the ecosystem by forcing animals to travel further for food and damaging sea floor habitats. However, its eventual melting could release nutrients that benefit ocean plankton and the broader food chain.
