This Micronesian island's tourism is built around the coral reef that rings it. Oaxaca offers spots along its coast like Playa Carrizalillo near Puerto Escondido and Huatulco. What underwater activity, which uses air tanks and needs a training course, draws visitors to both places?

Question

Accepted Answer

scuba diving. Scuba diving stands for Self-Contained Underwater Breathing Apparatus, and grew from the Aqua-Lung invented by Jacques Cousteau and Emile Gagnan in 1943. The coral reef ringing the island of Kosrae in Micronesia and the coast of Oaxaca in Mexico, at Puerto Escondido and Huatulco, both draw scuba visitors from around the world.
