Singapore

Singapore (ⁱ/ˈsɪŋɡəpɔːr/), officially the Republic of Singapore, and often referred to as the Lion City, the Garden City, and the Red Dot, is a global city in Southeast Asia and the world's only island city-state. It lies one degree (137 km) north of the equator, at the southernmost tip of continental Asia and peninsular Malaysia, with Indonesia's Riau Islands to the south. Singapore's territory consists of the diamond-shaped main island and 62 islets. Since independence, extensive land reclamation has increased its total size by 23% (130 km²), and its greening policy has covered the densely populated island with tropical flora, parks and gardens.

The islands were settled from the second century AD by a series of local empires. In 1819, Sir Stamford Raffles founded modern Singapore as a trading post of the East India Company; after the company collapsed, the islands were ceded to Britain and became part of its Straits Settlements in 1826. During World War II, Singapore was occupied by Japan. It gained independence from Britain in 1963, by uniting with other former British territories to form Malaysia, but was expelled two years later over ideological differences. After early years of turbulence, and despite lacking natural resources and a hinterland, the nation developed rapidly as an Asian tiger economy, based on external trade and its human capital.

Qiandao Lake

Qiandao Lake (Chinese: 千岛湖, lit. Thousand Island Lake), a human-made lake located in Chun'an County, Zhejiang Province, China, was formed after the completion of the Xin'an River hydroelectric station in 1959. 1,078 large islands dot the lake and a few thousand smaller ones are scattered across it. The lake covers an area of 573 km² (221 sq mi) and has a storage capacity of 17.8 km³ (4.3 cu mi). The islands in the lake cover about 86 km² (33 sq mi).

Qiandao Lake is used to produce the Nongfu Spring brand of mineral water. Over 90% of the area is forested. The islands in the lake include Bird Island, Snake Island, Monkey Island, Lock Island (featuring supposedly the world's biggest lock), and the Island to Remind You of Your Childhood.

The lake has made Zhejiang a popular area for tourists. As a result, housing development has increased in the area since the late 1990s.

The dam creating the lake is located at 29°29′01″N 119°12′48″E / 29.48361°N 119.21333°E / 29.48361; 119.21333 (Xin'an Dam) and is 105 m (344 ft) tall with a crest length of 466.5 m (1,531 ft). Xin'an Dam was the first dam constructed in China with a height greater than 100 m (328 ft) and its power plant has an installed capacity of 845 MW.

Lion

The lion (Panthera leo) is one of the five big cats in the genus Panthera and a member of the family Felidae. The commonly used term African lion collectively denotes the several subspecies found in Africa. With some males exceeding 250 kg (550 lb) in weight, it is the second-largest living cat after the tiger. Wild lions currently exist in sub-Saharan Africa and in Asia (where an endangered remnant population resides in Gir Forest National Park in India) while other types of lions have disappeared from North Africa and Southwest Asia in historic times. Until the late Pleistocene, about 10,000 years ago, the lion was the most widespread large land mammal after humans. They were found in most of Africa, across Eurasia from western Europe to India, and in the Americas from the Yukon to Peru. The lion is a vulnerable species, having seen a major population decline in its African range of 30–50% per two decades during the second half of the twentieth century. Lion populations are untenable outside designated reserves and national parks. Although the cause of the decline is not fully understood, habitat loss and conflicts with humans are currently the greatest causes of concern. Within Africa, the West African lion population is particularly endangered.

City

A city is a large and permanent human settlement. Although there is no agreement on how a city is distinguished from a town in general English language meanings, many cities have a particular administrative, legal, or historical status based on local law.

Cities generally have complex systems for sanitation, utilities, land usage, housing, and transportation. The concentration of development greatly facilitates interaction between people and businesses, benefiting both parties in the process, but it also presents challenges to managing urban growth.

A big city or metropolis usually has associated suburbs and exurbs. Such cities are usually associated with metropolitan areas and urban areas, creating numerous business commuters traveling to urban centers for employment. Once a city expands far enough to reach another city, this region can be deemed a conurbation or megalopolis. In terms of population, the largest city proper is Shanghai, while the fastest-growing is Dubai.

Origins

There is not enough evidence to assert what conditions gave rise to the first cities. Some theorists have speculated on what they consider suitable pre-conditions and basic mechanisms that might have been important driving forces.
