Life on a remote island is not without its challenges. Can you imagine living more than 1,000 miles away from the nearest anything? That's life for the most remote civilization on Earth, Tristan da Cunha. The small, 80-square-mile island sits 1,750 miles (2,816 kilometers) from South Africa and 2,088 miles (3,360 kilometers) from South America. Its closest landmass is 1,510 miles (2,430 kilometers) away, Saint Helena. It's part of the British overseas territory called Saint Helena, Ascension, and Tristan da Cunha. But how do these people survive so secluded from the rest of the world?
