The biggest iceberg on Earth is heading toward a remote island, creating a potential threat to penguins and seals inhabiting the area.

The trillion-ton slab of ice — called a megaberg — could slam into South Georgia Island, making it hard for penguin parents to feed their babies and some young could even starve.

A23a, a massive iceberg nearly the size of Rhode Island, towering at 40 meters, is on a collision course with South Georgia.
