Globally, the 20th century was
marked by: (a) two devastating world wars; (b) the Great Depression of the
1930s; (c) the end of vast colonial empires; (d) rapid advances in science
and technology, from the first airplane flight at Kitty Hawk, North
Carolina (US) to the landing on the moon; (e) the Cold War between the
Western alliance and the Warsaw Pact nations; (f) a sharp rise in living
standards in North America, Europe, and Japan; (g) increased concerns
about the environment, including loss of forests, shortages of energy and
water, the decline in biological diversity, and air pollution; (h) the
onset of the AIDS epidemic; and (i) the ultimate emergence of the US as
the only world superpower. The planet's population continues to explode:
from 1 billion in 1820, to 2 billion in 1930, 3 billion in 1960, 4 billion
in 1974, 5 billion in 1988, and 6 billion in 2000. For the 21st century,
the continued exponential growth in science and technology raises both
hopes (e.g., advances in medicine) and fears (e.g., development of even
more lethal weapons of war).

Maritime claims:
a variety of situations exist,
but in general, most countries make the following claims measured from the
mean low-tide baseline as described in the 1982 UN Convention on the Law
of the Sea: territorial sea - 12 nm, contiguous zone - 24 nm, and
exclusive economic zone - 200 nm; additional zones provide for
exploitation of continental shelf resources and an exclusive fishing zone;
boundary situations with neighboring states prevent many countries from
extending their fishing or economic zones to a full 200 nm
Climate:
two large areas of polar
climates separated by two rather narrow temperate zones form a wide
equatorial band of tropical to subtropical climates
Terrain:
the greatest ocean depth is the
Mariana Trench at 10,924 m in the Pacific Ocean
Elevation extremes:
lowest point: Bentley
Subglacial Trench -2,540 m note: in the oceanic realm,
Challenger Deep in the Mariana Trench is the lowest point, lying -10,924 m
below the surface of the Pacific Ocean highest point: Mount
Everest 8,850 m (1999 est.)
Natural resources:
the rapid depletion of
nonrenewable mineral resources, the depletion of forest areas and
wetlands, the extinction of animal and plant species, and the
deterioration in air and water quality (especially in Eastern Europe, the
former USSR, and China) pose serious long-term problems that governments
and peoples are only beginning to address
large areas subject to severe
weather (tropical cyclones), natural disasters (earthquakes, landslides,
tsunamis, volcanic eruptions)
Environment - current issues:
large areas subject to
overpopulation, industrial disasters, pollution (air, water, acid rain,
toxic substances), loss of vegetation (overgrazing, deforestation,
desertification), loss of wildlife, soil degradation, soil depletion,
erosion
Geography - note:
the world is now thought to be
about 4.55 billion years old, just about one-third of the 13-billion-year
age estimated for the universe

Economy
World
Economy - overview:
Global output rose by 3.7% in
2003, led by China (9.1%), India (7.6%), and Russia (7.3%). The other 14
successor nations of the USSR and the other old Warsaw Pact nations again
experienced widely divergent growth rates; the three Baltic nations
continued as strong performers, in the 5%-7% range of growth. Growth
results posted by the major industrial countries varied from a loss by
Germany (-0.1%) to a strong gain by the United States (3.1%). The
developing nations also varied in their growth results, with many
countries facing population increases that erode gains in output.
Externally, the nation-state, as a bedrock economic-political institution,
is steadily losing control over international flows of people, goods,
funds, and technology. Internally, the central government often finds its
control over resources slipping as separatist regional movements -
typically based on ethnicity - gain momentum, e.g., in many of the
successor states of the former Soviet Union, in the former Yugoslavia, in
India, in Iraq, in Indonesia, and in Canada. Externally, the central
government is losing decision-making powers to international bodies. In
Western Europe, governments face the difficult political problem of
channeling resources away from welfare programs in order to increase
investment and strengthen incentives to seek employment. The addition of
80 million people each year to an already overcrowded globe is
exacerbating the problems of pollution, desertification, underemployment,
epidemics, and famine. Because of their own internal problems and
priorities, the industrialized countries devote insufficient resources to
deal effectively with the poorer areas of the world, which, at least from
the economic point of view, are becoming further marginalized. The
introduction of the euro as the common currency of much of Western Europe
in January 1999, while paving the way for an integrated economic
powerhouse, poses economic risks because of varying levels of income and
cultural and political differences among the participating nations. The
terrorist attacks on the US on 11 September 2001 accentuate a further
growing risk to global prosperity, illustrated, for example, by the
reallocation of resources away from investment to anti-terrorist programs.
The opening of war in March 2003 between a US-led coalition and Iraq added
new uncertainties to global economic prospects. After the coalition
victory, the complex political difficulties and the high economic cost of
establishing domestic order in Iraq became major global problems that
continue into 2004.

Transnational Issues
World
Disputes - international:
stretching over 250,000 km, the
world's 325 international land boundaries separate the 192 independent
states and 72 dependencies, areas of special sovereignty, and other
miscellaneous entities; ethnicity, culture, race, religion, and language
have divided states into separate political entities as much as history,
physical terrain, political fiat, or conquest, resulting in sometimes
arbitrary and imposed boundaries; maritime states have claimed limits and
have so far established over 130 maritime boundaries and joint development
zones to allocate ocean resources and to provide for national security at
sea; boundary, borderland/resource, and territorial disputes vary in
intensity from managed or dormant to violent or militarized; most disputes
over the alignment of political boundaries are confined to short segments
and are today less common and less hostile than borderland, resource, and
territorial disputes; undemarcated, indefinite, porous, and unmanaged
boundaries, however, encourage illegal cross-border activities,
uncontrolled migration, and confrontation; territorial disputes may evolve
from historical and/or cultural claims, or they may be brought on by
resource competition; ethnic clashes continue to be responsible for much
of the territorial fragmentation around the world; disputes over islands
at sea or in rivers frequently form the source of territorial and boundary
conflict; other sources of contention include access to water and mineral
(especially petroleum) resources, fisheries, and arable land; nonetheless,
most nations cooperate to clarify their international boundaries and to
resolve territorial and resource disputes peacefully; regional discord
directly affects the sustenance and welfare of local populations, often
leaving the world community to cope with resultant refugees, hunger,
disease, impoverishment, deforestation, and desertification
Illicit drugs:
cocaine: worldwide, coca
is grown on an estimated 173,450 hectares-almost exclusively in South
America with 70% in Colombia; potential cocaine production during 2003 is
estimated at 728 metric tons (or 835 metric tons of export quality
cocaine); coca eradication programs continue in Bolivia, Colombia, and
Peru; 376 metric tons of export quality cocaine are documented to have
been seized in 2003, and 26 metric tons disrupted (jettisoned or
destroyed); consumption of export quality cocaine is estimated to have
been 800 metric tons opiates: cultivation of opium poppy
occurred on an estimated 137,944 hectares in 2003-mostly in Southwest and
Southeast Asia-with 44% in Afghanistan, potentially produced 3,775 metric
tons of opium - which conceivably could be converted to the equivalent of
429 metric tons of pure heroin; opium eradication programs have been
undertaken in Afghanistan, Burma, Colombia, Mexico, Pakistan, Thailand,
and Vietnam
