Travelling by sea
  • Many people enjoy travelling by sea. They say it
    is the most exciting means of travelling, of
    course, they mean travelling by a big ocean liner
    because it combines comfort and speed. But
    smaller ships are less comfortable and in stormy
    seas passengers feel unhappy, they get sea-sick
    and travelling by sea becomes a real torture for
    them.

The Pacific Ocean
  • The Pacific ocean is the largest of all oceans.
    It covers about 181 square kilometers nearly a
    third of the Earth surface. The Pacific contains
    about half the water in the world ocean.
  • The deepest known depth is found there. It is the
    Mariana Trench and it lies 11 033 meters below
    sea level.
  • In the Pacific there are a lot of storms and
    ship-wrecks.

Great barrier reef
  • The Australian Great barrier reef is the largest
    coral reef in the world. It is 2000 km long and
    can be seen from space. Corals make wonderful
    shapes. Some look like trees, others look like
    flowers. In the great barrier reef there are more
    than 400 tips of coral. There are more than 1 500
    species of fish. The blue parrot fish has
    beaklike jaws. When young, these fish are light
    blue, they turn darker blue as they get older.

The Sea inhabitants
  • Turtles are the most common reptiles on the great
    barrier reef and six of the worlds seven turtle
    species live here. There are fish jazz band
    trumped fish, guitar fish, pipe fish. The fish
    you can see in the picture is a trumpet fish.

The Big Problem
  • Today, the ocean needs help. Ships dump toxic
    waste, tankers leak and spill oil, boaters throw
    trash overboard
  • Many people dont realize just how vital the
    ocean is. Without the ocean, the Earth would be
    just another barren rocky planet, circling the
    sun. The ocean gives us food, energy and
    minerals. It regulates the air and helps to keep
    the environment healthful.

What can we do?
  • Everyone can help. Here are a few more things you
    can do today
  • Protect ocean birds and marine life dont throw
    plastic things .
  • Dont litter. Rubbish has the way of ending up in
    rivers, lakes, and the oceans.
  • Take part in beach clean-up projects.
