Detroit vs Sarnia

Informations

Detroit (, locally also ; French: Détroit, lit. 'strait') is the largest and most-populous city in the U.S. state of Michigan, the largest U.S. city on the United States–Canada border, and the seat of Wayne County. The municipality of Detroit had a 2019 estimated population of 670,031, making it the 24th-most populous city in the United States. The metropolitan area, known as Metro Detroit, is home to 4.3 million people, making it the second-largest in the Midwest after the Chicago metropolitan area, and 14th-largest in the United States. Regarded as a major cultural center, Detroit is known for its contributions to music and as a repository for art, architecture and design.Detroit is a major port on the Detroit River, one of the four major straits that connect the Great Lakes system to the Saint Lawrence Seaway. The City of Detroit anchors the second-largest regional economy in the Midwest, behind Chicago and ahead of Minneapolis–Saint Paul, and the 13th-largest in the United States. Detroit is best known as the center of the U.S. automobile industry, and the "Big Three" auto manufacturers General Motors, Ford, and Fiat Chrysler are all headquartered in Metro Detroit. As of 2007, the Detroit metropolitan area is the number one exporting region among 310 defined metropolitan areas in the United States.The Detroit Metropolitan Airport is among the most important hubs in the United States. Detroit and its neighboring Canadian city Windsor are connected through a highway tunnel, railway tunnel, and the Ambassador Bridge, which is the second busiest international crossing in North America, after San Diego–Tijuana.In 1701, Antoine de la Mothe Cadillac founded Fort Pontchartrain du Détroit, the future city of Detroit. During the late nineteenth and early twentieth century, it became an important industrial hub at the center of the Great Lakes region. The city's population became the 4th-largest in the nation in 1920, after only New York City, Chicago and Philadelphia, with expansion of the auto industry in the early 20th century.

As Detroit's industrialization took off, the Detroit River became the busiest commercial hub in the world. The strait carried over 65 million tons of shipping commerce through Detroit to locations all over the world each year; the freight throughput was more than three times that of New York and about four times that of London. By the 1940s, the city's population remained as the fourth-largest in the country. However, due to industrial restructuring, the loss of jobs in the auto industry, and rapid suburbanization, Detroit entered a state of urban decay and lost considerable population from the late 20th century to the present. Since reaching a peak of 1.85 million at the 1950 census, Detroit's population has declined by more than 60 percent. In 2013, Detroit became the largest U.S. city to file for bankruptcy, which it successfully exited in December 2014, when the city government regained control of Detroit's finances.Detroit's diverse culture has had both local and international influence, particularly in music, with the city giving rise to the genres of Motown and techno, and playing an important role in the development of jazz, hip-hop, rock, and punk music. The rapid growth of Detroit in its boom years resulted in a globally unique stock of architectural monuments and historic places. Since the 2000s conservation efforts have managed to save many architectural pieces and achieved several large-scale revitalizations, including the restoration of several historic theatres and entertainment venues, high-rise renovations, new sports stadiums, and a riverfront revitalization project. More recently, the population of Downtown Detroit, Midtown Detroit, and various other neighborhoods has increased. An increasingly popular tourist destination, Detroit receives 19 million visitors per year. In 2015, Detroit was named a "City of Design" by UNESCO, the first U.S. city to receive that designation.

Sarnia is a city in Southwestern Ontario, Canada, with a 2016 population of 71,594. It is the largest city on Lake Huron and in Lambton County. Sarnia is located on the eastern bank of the junction between the Upper and Lower Great Lakes where Lake Huron flows into the St. Clair River, which forms the Canada–United States border, directly across from Port Huron, Michigan. The site's natural harbour first attracted the French explorer La Salle. He named the site "The Rapids" on 23 August 1679, when he had horses and men pull his 45-ton barque Le Griffon north against the nearly four-knot current of the St. Clair River.This was the first time that a vessel other than a canoe or other oar-powered vessel had sailed into Lake Huron, and La Salle's voyage was germinal in the development of commercial shipping on the Great Lakes. Located in the natural harbour, the Sarnia port remains an important centre for lake freighters and oceangoing ships carrying cargoes of grain and petroleum products. The natural port and the salt caverns that exist in the surrounding areas, together with the oil discovered in nearby Oil Springs in 1858, led to the dramatic growth of the petroleum industry in this area.

Because Oil Springs was the first place in Canada and North America to drill commercially for oil, the knowledge that was acquired there resulted in oil drillers from Sarnia travelling the world teaching other enterprises and nations how to drill for oil.The complex of refining and chemical companies is called Chemical Valley and located south of downtown Sarnia. In 2011 the city had the highest level of particulates air pollution of any Canadian city, but it has since dropped to rank 30th in this hazard. About 60 percent of the particulate matter comes from industries and polluters in the neighbouring United States.Lake Huron is cooler than the air in summer and warmer than the air in winter; therefore, it moderates Sarnia's humid continental climate, making temperature extremes of hot and cold less evident. In the winter, Sarnia occasionally experiences lake-effect snow from Arctic air blowing across the warmer waters of Lake Huron and condensing to form snow squalls over land.
