Mineral extraction, principally diamond mining,
dominates economic activity, though tourism is a growing sector due
to the country's conservation practices and extensive nature
preserves. Botswana has one of the world's highest known rates of
HIV/AIDS infection, but also one of Africa's most progressive and
comprehensive programs for dealing with the disease.

Bouvet Island
This uninhabited volcanic island is almost entirely
covered by glaciers and is difficult to approach. It was discovered
in 1739 by a French naval officer after whom the island was named.
No claim was made until 1825, when the British flag was raised. In
1928, the UK waived its claim in favor of Norway, which had occupied
the island the previous year. In 1971, Norway designated Bouvet
Island and the adjacent territorial waters a nature reserve. Since
1977, it has run an automated meteorological station on the island.

Brazil
Following three centuries under the rule of Portugal, Brazil
became an independent nation in 1822 and a republic in 1889. By far
the largest and most populous country in South America, Brazil
overcame more than half a century of military intervention in the
governance of the country when in 1985 the military regime
peacefully ceded power to civilian rulers. Brazil continues to
pursue industrial and agricultural growth and development of its
interior. Exploiting vast natural resources and a large labor pool,
it is today South America's leading economic power and a regional
leader. Highly unequal income distribution and crime remain pressing
problems.

British Indian Ocean Territory
Formerly administered as part of the
British Crown Colony of Mauritius, the British Indian Ocean
Territory (BIOT) was established as an overseas territory of the UK
in 1965. A number of the islands of the territory were later
transferred to the Seychelles when it attained independence in 1976.
Subsequently, BIOT has consisted only of the six main island groups
comprising the Chagos Archipelago. The largest and most southerly of
the islands, Diego Garcia, contains a joint UK-US naval support
facility. All of the remaining islands are uninhabited. Between 1967
and 1973, former agricultural workers, earlier residents in the
islands, were relocated primarily to Mauritius, but also to the
Seychelles. Negotiations between 1971 and 1982 resulted in the
establishment of a trust fund
