Giant Iceberg's 37-Year Journey Poses Wildlife Threat

A23a, the world's biggest iceberg, is on the move after 37 years and is set to enter the Atlantic Ocean. Scientists are concerned that it could threaten wildlife near South Georgia Island if it gets stuck in shallow waters, cutting off the animals' access to food. However, there is also the possibility that as the iceberg melts, it could disperse minerals from the ocean floor, providing nutrients for local wildlife.
