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

Land use:
arable land: 10.73%
permanent crops: 1%
other: 88.27% (2001)

Irrigated land:
2,714,320 sq km (1998 est.)

Natural hazards:
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 o
