The Bajau’s Incredible Diving Adventures
In Deep Breath: The Bajau’s Incredible Diving Adventures, Simon explores the world of the Bajau, a community of sea nomads who live in homes built on stilts above the coral reefs. He meets Bari, a skilled diver who shows him the underwater world of the coral triangle. Bari dives 50 to 65 feet (15 to 20 meters) deep on a single breath, and Simon learns the Bajau have evolved to hold more oxygen in their blood, allowing them to stay underwater for long periods of time! This video is excerpted from BBC’s Wilderness With Simon Reeve, an epic adventure into the heart of Earth’s last great wild areas, where nature is at its most beautiful and fragile.
Lesson Express
Q: How does the Bajau community's ability to dive deep for extended periods reflect their unique relationship with the ocean?
A: The Bajau’s ability to dive for long periods of time, even up to 12 minutes, is a result of their evolved physiology, allowing them to absorb and hold more oxygen in their blood. This adaptation highlights their deep connection to the ocean, as they rely on the sea for food and survival. It also demonstrates how their bodies have adjusted over generations to thrive in this specific environment.
Q: Why do you think the Bajau’s sustainable fishing methods are important for the health of the coral reef ecosystem?
A: The Bajau’s sustainable fishing methods help preserve the delicate balance of the coral reef ecosystem. By spearfishing and not over-harvesting, they ensure that the reef remains healthy and continues to provide resources for future generations.
Q: How might the Bajau community’s way of life challenge our understanding of human adaptation to extreme environments?
A: The Bajau community’s ability to survive and thrive in an extreme underwater environment challenges the conventional understanding of human adaptation. Their evolved ability to hold more oxygen in their blood shows how humans can adapt to unique environmental pressures over time. This adaptation challenges our assumptions about the limits of human endurance and survival in extreme conditions.
