Twelve Thai boys found alive in a flooded cave Monday after spending the past nine days trapped inside will have to learn to scuba dive in order to escape or remain there for months while the water recedes. Rescue divers found the boys, aged 11 to 16, and their soccer coach safe and sound Monday night, just when many were beginning to fear the worst. But Thai authorities now say the boys’ ordeal isn’t quite over yet, as the flooded corridors of the Tham Luang cave complex make their evacuation impossible. Attempts to lower the water levels have so far been unsuccessful, leaving them with two options: Learn to dive and swim out with masks and oxygen tanks, or remain inside until water levels drop and rely on food supplies to be brought in. Authorities say the final decision will be up to a navy team, but experts have warned the risks are “exponentially greater” if the boys attempt to swim out of the cave.
