VI. Reading:
People have been hunting whales for at least a thousand years, and there were no real problems until 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
become too late. Let’s take the great blue whale for example, which at thirty to forty metres long is the
biggest animal there has ever been – now there are perhaps about two thousand or so left. In fact they have
been protected for quite a long time, but there is no sign that the population is growing.
