The Law to Keep the Oil Industry under Control
The Norwegian Government is doing its best to keep the oil industry under control.A new law limits exploration to an area south of the southern end of the long coastline;production limits have been laid down(though these have already been
raised);and oil companies have not been allowed to employ more than a limited number of foreign workers.But the oil industry has a way of getting over such problems,and few people believe that the Government will be able to hold things back for long.As on Norwegian politician said last week:“We will soon be changed beyond all recognition.”
Ever since the war,the Government has been carrying out a programme of development in the area north of the Arctic
Circle.During the past few years this programme has had a great deal of success:Tromso has been built up into a local
capital with a university,a large hospital and a healthy industry.But the oil industry has already started to draw people south,
and within a few years the whole northern policy could be in ruins.
The effects of the oil industry would not be limited to the north,however.With nearly 100 percent employment,everyone
can see a situation developing in which the service industries and the tourist industry will lose more of their workers to the oil
industry.Some smaller industries might even disappear altogether when it becomes cheaper to buy goods from abroad.The
real argument over oil is its threat to the Norwegian way of life.Farmers and fishermen do not make up most of the population,but they are an important part of it,because Norwegians see in them many of the qualities that they regard with pride as
essentially Norwegian.And it is the farmers and the fishermen who are most critical of the oil industry because of the damage
that it might cause to the countryside and to the sea.
The Norwegian Government has tried to ______.A.encourage the oil companies to discover new oil sources.
B.prevent oil companies employing people from northern Norway.
C.help the oil companies solve many of their problems.
D.keep the oil industry to something near its present size.
