Land boundaries: the land boundaries in the world total 250,883.64 km
(not counting shared boundaries twice)

Coastline: 356,000 km

Maritime claims:
contiguous zone: 24 nm claimed by most but can vary
continental shelf: 200-m depth claimed by most or to depth of
exploitation, others claim 200 nm or to the edge of the continental
margin
exclusive fishing zone: 200 nm claimed by most but can vary
exclusive economic zone: 200 nm claimed by most but can vary
territorial sea: 12 nm claimed by most but can vary
note: boundary situations with neighboring states prevent many
countries from extending their fishing or economic zones to a full 200
nm; 43 nations and other areas that are landlocked include
Afghanistan, Andorra, Armenia, Austria, Azerbaijan, Belarus, Bhutan,
Bolivia, Botswana, Burkina, Burundi, Central African Republic, Chad,
Czech Republic, Ethiopia, Holy See (Vatican City), Hungary,

Climate: two large areas of polar climates separated by two rather
narrow temperate zones from a wide equatorial band of tropical to
subtropical climates

Terrain: highest elevation is Mt. Everest at 8,848 meters and lowest
depression is the Dead Sea at 392 meters below sea level; greatest
ocean depth is the Marianas Trench at 10,924 meters

Natural resources: the rapid using up 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 and the former USSR) pose
serious long-term problems that governments and peoples are only
beginning to address

Land use:
arable land: 10%
permanent crops: 1%
meadows and pastures: 24%
forest and woodland: 31%
other: 34%

Irrigated land: NA sq km

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
natural hazards: large areas subject to severe weather (tropical
cyclones), natural dis
