The richest country
To reach the world's richest country, you needn't set out for the Middle East, but for the South Pacific, to a
tiny dot just south of the equator, called Nauru. Only 8.2 square miles in size, the whole of this country can be
seen from the air as the plane comes into land. The blue South Pacific reaches for thousands of miles in all
directions, the nearest piece of land being Ocean Island 200 miles to the east.
Nauro is so small that the plane lands in what is best regarded as the capital's main street. The seaward
side of the runway has traffic lights at each end to stop cars when planes are landing. The tiny bus station
outside the airport is crowded with well-fed and brightly clothed Naurans with their modern cars.
With Naurans now getting an average(平均) of $44,500 a year, the island's 60,000 people seem to have little
to worry about. A trip to the island's central hump(隆峰) tells a slightly different story.
The hump with a great deal of phosphate (磷酸盐) round is Nauru's wealth. When Nauru gained freedom
from the British government in 1908, about 40 million tons of the earliest 100 million tons of phosphate were
left. Since it has taken out another 10 million tons, which leaves enough only for another 20-25 years.
