Political Map of the World

Area:

total: 155.557 million sq km note: includes Bali Sea, Bering Sea, Bering Strait, Coral Sea, East China Sea, Gulf of Alaska, Gulf of Tonkin, Philippine Sea, Sea of Japan, Sea of Okhotsk, South China Sea, Tasman Sea, and other tributary water bodies

Area - comparative:

about 15 times the size of the US; covers about 28% of the global surface; larger than the total land area of the world

Coastline:

135,663 km

Climate:

planetary air pressure systems and resultant wind patterns exhibit remarkable uniformity in the south and east; trade winds and westerly winds are well-developed patterns, modified by seasonal fluctuations; tropical cyclones (hurricanes) may form south of Mexico from June to October and affect Mexico and Central America; continental influences cause climatic uniformity to be much less pronounced in the eastern and western regions at the same latitude in the North Pacific Ocean; the western Pacific is monsoonal - a rainy season occurs during the summer months, when moisture-laden winds blow from the ocean over the land, and a dry season during the winter months, when dry winds blow from the Asian landmass back to the ocean; tropical cyclones (typhoons) may strike southeast and east Asia from May to December

Terrain:

surface currents in the northern Pacific are dominated by a clockwise, warm-water gyre (broad circular system of currents) and in the southern Pacific by a counterclockwise, cool-water gyre; in the northern Pacific, sea ice forms in the Bering Sea and Sea of Okhotsk in winter; in the southern Pacific, sea ice from Antarctica reaches its northernmost extent in October; the ocean floor in the eastern Pacific is dominated by the East Pacific Rise, while the western Pacific is dissected by deep trenches, including the Mariana Trench, which is the world's deepest

Elevation extremes:

lowest point: Challenger Deep in the Mariana Trench -10,924 m highest point: sea level 0 m

Natural resources:

oil and gas fields, polymetallic nodules, sand and gravel aggregates, placer deposits, fish

Natural hazards:

surrounded by a zone of violent volcanic and earthquake activity sometimes referred to as the "Pacific Ring of Fire"; subject to tropical cyclones (typhoons) in southeast and east Asia from May to December (most frequent from July to October); tropical cyclones (hurricanes) may form south of Mexico and strike Central America and Mexico from June to October (most common in August and September); cyclical El Nino/La Nina phenomenon occurs in the equatorial Pacific, influencing weather in the Western Hemisphere and the western Pacific; ships subject to superstructure icing in extreme north from October to May; persistent fog in the northern Pacific can be a maritime hazard from June to December

Environment - current issues:

endangered marine species include the dugong, sea lion, sea otter, seals, turtles, and whales; oil pollution in Philippine Sea and South China Sea

Geography - note:

the major chokepoints are the Bering Strait, Panama Canal, Luzon Strait, and the Singapore Strait; the Equator divides the Pacific Ocean into the North Pacific Ocean and the South Pacific Ocean; dotted with low coral islands and rugged volcanic islands in the southwestern Pacific Ocean

Economy
Pacific Ocean

Economy - overview:

The Pacific Ocean is a major contributor to the world economy and particularly to those nations its waters directly touch. It provides low-cost sea transportation between East and West, extensive fishing grounds, offshore oil and gas fields, minerals, and sand and gravel for the construction industry. In 1996, over 60% of the world's fish catch came from the Pacific Ocean. Exploitation of offshore oil and gas reserves is playing an ever-increasing role in the energy supplies of the US, Australia, NZ, China, and Peru. The high cost of recovering offshore oil and gas, combined with the wide swings in world prices for oil since 1985, has led to fluctuations in new drillings.

Transportation
Pacific Ocean

Ports and terminals:

Bangkok (Thailand), Hong Kong (China), Kao-hsiung (Taiwan), Los
Angeles (US), Manila (Philippines), Pusan (South Korea), San
Francisco (US), Seattle (US), Shanghai (China), Singapore, Sydney
(Australia), Vladivostok (Russia), Wellington (NZ), Yokohama (Japan)

Transportation - note:

Inside Passage offers protected waters from southeast Alaska to Puget Sound (Washington state); the International Maritime Bureau reports the territorial waters of littoral states and offshore waters in the South China Sea as high risk for piracy and armed robbery against ships; numerous commercial vessels have been attacked and hijacked both at anchor and while underway; hijacked vessels are often disguised and cargoes stolen; crew and passengers are often held for ransom, murdered, or cast adrift

Introduction
Pakistan

Background:

The Indus Valley civilization, one of the oldest in the world and dating back at least 5,000 years, spread over much of what is presently Pakistan. During the second millennium B.C., remnants of this culture fused with the migrating Indo-Aryan peoples. The area underwent successive invasions in subsequent centuries from the Persians, Greeks, Scythians, Arabs (who brought Islam), Afghans, and Turks. The Mughal Empire flourished in the 16th and 17th centuries; the British came to dominate the region in the 18th century. The separation in 1947 of British India into the Muslim state of Pakistan (with West and East sections) and largely Hindu India was never satisfactorily resolved, and India and Pakistan fought two wars - in 1947-48 and 1965 - over the disputed Kashmir territory. A third war between these countries in 1971 - in which India capitalized on Islamabad's marginalization of Bengalis in Pakistani politics - resulted in East Pakistan becoming the separate nation of Bangladesh. In response to Indian nuclear weapons testing, Pakistan conducted its own tests in 1998. The dispute over the state of Kashmir is ongoing, but discussions and confidence-building measures have led to decreased tensions since 2002. Mounting public dissatisfaction with President MUSHARRAF, coupled with the assassination of the prominent and popular political leader, Benazir BHUTTO, in late 2007, and MUSHARRAF?s resignation in August 2008, led to the September presidential election of Asif ZARDARI, BHUTTO?s widower. Pakistani government and military leaders are struggling to control Islamist militants, many of whom are located in the tribal areas adjacent to the border with Afghanistan. The Pakistani government is also faced with a deteriorating economy as foreign exchange reserves decline, the currency depreciates, and the current account deficit widens.
