Students will read about the importance of coral reefs to the ecology of our planet. Our coral reefs are in danger and we need to work together to rescue them.
Oil companies, careless divers, and an invasion by crown-of-thorns starfish threaten the Great Barrier Reef. The reef – a 30-million-year-old limestone formation-needs protection.
Oil companies want to drill the reef area, while some divers wish to collect souvenirs of the reef itself. Collectors prize its brightly colored formations. Australia has made most of the reef a national park and created laws against drilling or collecting. However, scientists have yet to solve the problem of invasions of crown-of-thorns starfish, which have multiplied out of control at times and eat the animals that form coral reefs.
1. Coral are tiny ocean animals that live tightly-packed together in groups. 2. In warm, shallow seas the shells of these tiny animals eventually form reefs. 3. Sadly, up to 60 percent or a bit more than half of these coral reefs may be destroyed in the next 45 years. 4. The damage to the coral is related to harmful human actions. 5. When people clear land, loosened dirt washes into the sea. 6. The tons of dirt fill the water and block the light that algae plants, which play an important role in building coral reefs, need to survive.
There are three types of coral reefs: fringing reefs, barrier reefs, and atolls. A fringing reef grows from the edge of the land, such as the shore of a beach, with no water between the reef and the land.
The barrier reef is farther off the shore. It acts as a barrier, or a block, between the water near the shore and the open ocean. An atoll is an island made of coral. It usually has a narrow horseshoe shape surrounding a body of shallow water known as a lagoon.
The Great Barrier Reef is a chain of coral reefs in the Coral Sea, off the northeastern coast of Australia.
The 1,250-mile-long (2,000 km) reef protects the mainland from being hammered by harsh winds and waves.
The Great Barrier Reef is currently experiencing a problem. An animal called the crown-of-thorns starfish has invaded the reef and is killing the coral. No one knows if the coral will be able to bounce back.
