Title: Can We Rescue the Reefs


1
Can We Rescue the Reefs?
  • Genre Science Article Non-fiction
  • 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.

Protecting the Reef (TC 145)
  • 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.

Coral Reefs (TC 146)
  • 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.

4
Name That Reef (TC 148)
  • 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.

5
The Great Barrier Reef (TC 149)
  • 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.
