<p> The title of this bok is 'Natural Wonder, the Freat Barrier Reef'. The Great Barrier Reef off the coast of eastern Austrailia. It spreads almost 350,000 square kilometers, and contains numerous reefs and islands. It was seen by Europeans for the first time in the 1700s. Many sea animals contains coral and whales are living in this reef. Unfortunately, it is getting vulnerable because of the overfishing, oil spills, and the changing climate. However researchers study changes in the ecosystem and teech people how to keep it safe. We should preserve this vaulable and beautiful piece of the ocean. I want to snorkeling there to sea turtles and whales when I grew up.</p>
