Exploring the Oceans

洋世界到底有多少未知的秘密?
Ever wonder what lives in the Earth’s waters? Some 300 scientists from
53 different countries are wondering the same thing. For the first time in
history, scientists are trying to count how many species of fish, animals
and plants live under water. 
They are conducting a census of life in the world’s oceans, which
cover 70 per cent of the Earth’s surface. The study began in 2000 and is
expected to end in 2010, at a cost of US$1 billion. So far, scientists have
counted more than 15,000 species of fish and around 200,000 species of
animals and plants in the oceans. They expect to find at least another
5,000 species of fish. 
Scientists believe that the animals and plants they’ve found so far
represent just 10 per cent of the world’s total underwater population. That
means that they expect to find almost 2 million species of animals and

plants by 2010. “Our goal by 2010 is to know as much about life in the
oceans as we know about life on land now,” says a marine biologist who
is working on the project. 
The newly-discovered species are not all new species. Many of them
have just never been recorded before. Scientists fear that the growing
human population is decreasing the variety of species living in the ocean.
They hope the census will help them learn how human activity, such as
fishing and agriculture, is affecting the oceans.
