India's North Sentinel Island Tribal Reserve Remains Intact

The North Sentinel Island tribal reserve in India's Andaman and Nicobar archipelago remains a pristine ecosystem, thanks to the Sentinelese people's voluntary isolation. The island's coastal reefs are intact, rich in fish life, and home to mangroves that serve as excellent nurseries for marine biodiversity. The Sentinelese people have been observed spear fishing, hunting turtles, and collecting mollusks in shallow reefs. Their knowledge of the island's resources is evident in their ability to forage for nutritious food during low tide. The island's giant trees provide a natural defense against storms and hold the coastal soil together, while the shore is lined with sandy beaches and rocky shores.
