I also saw one segment, where a PHD, who had spent 20 years studying a very primitive tribe that existed on a few very small islands very close to the origin of the Tsunami. He was anxious to return to these islands as he expected the people to be devastated, much as on the mainland. Much to his surprise, not one member of the tribe died during the Tsunami waves that swept their islands. They had learned spiritual lessons from their ancestors, that when the water goes out, as it did first, their people are to flee inland, which they did, and which saved them all. That's being in touch with the nature around you.
The elephants, on the mainland, fled inland too--something that they too learned from their ancestors.
