A city is a human settlement of notable size. It can be defined as a permanent and densely settled place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organisations and businesses, sometimes benefiting different parties in the process, such as improving efficiency of goods and service distribution.

Historically, city-dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization, more than half of the world population now lives in cities, which has had profound consequences for global sustainability. Present-day cities usually form the core of larger metropolitan areas and urban areas—creating numerous commuters traveling towards city centres for employment, entertainment, and education. However, in a world of intensifying globalization, all cities are to varying degrees also connected globally beyond these regions. This increased influence means that cities also have significant influences on global issues, such as sustainable development, global warming, and global health. Because of these major influences on global issues, the international community has prioritized investment in sustainable cities through Sustainable Development Goal 11. Due to the efficiency of transportation and the smaller land consumption, dense cities hold the potential to have a smaller ecological footprint per inhabitant than more sparsely populated areas. Therefore, compact cities are often referred to as a crucial element of fighting climate change. However, this concentration can also have significant negative consequences, such as forming urban heat islands, concentrating pollution, and stressing water supplies and other resources.

Russia Saint Petersburg locator map.svg

Saint Petersburg (Russian: Санкт-Петербург, tr. Sankt-Peterburg, IPA: [ˈsankt pʲɪtʲɪrˈburk] (listen)), formerly known as Petrograd (1914–1924) and later Leningrad (1924–1991), is the second-largest city in Russia. It is situated on the Neva River, at the head of the Gulf of Finland on the Baltic Sea, with a population of roughly 5.4 million residents. Saint Petersburg is the fourth-most populous city in Europe after Istanbul, Moscow and London, the most populous city on the Baltic Sea, and the world's northernmost city of more than 1 million residents. As Russia's Imperial capital, and a historically strategic port, it is governed as a federal city.

The city was founded by Tsar Peter the Great on 27 May 1703 on the site of a captured Swedish fortress, and was named after apostle Saint Peter. In Russia, Saint Petersburg is historically and culturally associated with the birth of the Russian Empire and Russia's entry into modern history as a European great power. It served as a capital of the Tsardom of Russia, and the subsequent Russian Empire, from 1713 to 1918 (being replaced by Moscow for a short period of time between 1728 and 1730). After the October Revolution in 1917, the Bolsheviks moved their government to Moscow. (Full article...)

Looking south into downtown Dawson Creek, with the Mile "0" post.

Dawson Creek is a city in northeastern British Columbia, Canada. The municipality of 24.37 square kilometres (9.41 sq mi) had a population of 12,978 in 2016. Dawson Creek derives its name from the creek of the same name that runs through the community. The creek was named after George Mercer Dawson by a member of his land survey team when they passed through the area in August 1879. Once a small farming community, Dawson Creek became a regional centre after the western terminus of the Northern Alberta Railways was extended there in 1932. The community grew rapidly in 1942 as the US Army used the rail terminus as a transshipment point during construction of the Alaska Highway. In the 1950s, the city was connected to the interior of British Columbia via a highway and a railway through the Rocky Mountains. Since the 1960s, growth has slowed, but the area population has increased.

Dawson Creek is located in the dry and windy prairie land of the Peace River Country. As the seat of the Peace River Regional District and a service centre for the rural areas south of the Peace River, the city has been called the "Capital of the Peace". It is also known as the "Mile 0 City", referring to its location at the southern end of the Alaska Highway. It also has a heritage interpretation village, an art gallery, and a museum. Annual events include a fall fair and rodeo. (Full article...)
