Sarnia vs Gdynia

Informations

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.

Gdynia ( gə-DIN-ee-ə; Polish: [ˈɡdɨɲa] (listen); German: Gdingen; Kashubian: Gdiniô, 1939-1945 Gotenhafen) is a city in northern Poland. Located on Gdańsk Bay on the southern coast of the Baltic Sea, it is a major seaport and the second-largest city in Pomeranian Voivodeship after Gdańsk. Gdynia has a population of 246,348, which makes it the twelfth-largest city in Poland. It is part of a conurbation with the spa town of Sopot, the city of Gdańsk, and suburban communities, which together form a metropolitan area called the Tricity (Trójmiasto), with a population of over 1,000,000 people. Historically and culturally part of Kashubia in Eastern Pomerania, Gdynia for centuries remained a small farming and fishing village. At the beginning of the 20th-century, Gdynia attracted visitors as a seaside resort town, and began to build tourism. The local population increased in response to the change in the economy. After Poland regained its independence in 1918, the government decided to construct a Polish seaport in Gdynia, between the Free City of Danzig (a semi-autonomous city-state) and German Pomerania, making Gdynia a primary economic hub. In 1926 Gdynia was granted city rights, after which it enjoyed a rapid demographic and architectural development. This was interrupted by the outbreak of World War II, during which the newly built port and shipyard were completely destroyed.

The population of the city suffered heavy losses, as most of the inhabitants were evicted and expelled by the German occupiers. The locals were either displaced to other regions of occupied Poland or sent to German Nazi concentration camps throughout Europe. After the war, Gdynia was settled with the former inhabitants of Warsaw, which also suffered major destruction, and lost cities, such as Lviv and Vilnius in the Eastern Borderlands. The city was gradually regenerating, with its shipyard being rebuilt and expanded. In December 1970 the shipyard workers' protest against an increase in government-established prices was violently repressed by government forces. This greatly contributed to the rise of the Solidarity movement in nearby Gdańsk. Today the port of Gdynia is a regular stopover on the cruising itinerary of large, luxury passenger ships. A new ferry terminal with a civil airport are under development. The city has won numerous awards for its safety, infrastructure, quality of life, and a rich variety of tourist attractions. In 2013 Gdynia was ranked by readers of The News as Poland's best city to live in, and topped the national rankings in the category of "general quality of life".
