IV. READING: Read the passage and make the correct choice
People have been hunting whales for at least a thousand years, and there were no real problems until
the 20
th century . What happened was that : fishing technology became much more efficient and the
ships were much faster, so more and more whales were caught. In the 1960s the main whaling
countries were killing more than sixty thousand whales a year, and everyone began to realize that
something had to be done.
It was environmental groups like Greenpeace that really made things change. They set out to make
people aware of the fact that whales were fast becoming extinct . But even now we don’t know if all
this interest has come to late. Let’s take the great blue whale for example, which at thirty to forty
meters long is the biggest animal there has ever been- now there are perhaps a bout two thousand or so
left. In fact they have been protected for quite a long time, but there is still no sign that the population
is growing.
