Sarnia vs Lahore

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.

Lahore (; Punjabi: لہور; Urdu: لاہور‎, pronounced [lɑːˈɦɔːr]) is the capital of the Pakistani province of Punjab, and is the country's 2nd largest city after Karachi, as well as the 18th largest city proper in the world. Lahore is one of Pakistan's wealthiest cities with an estimated GDP of $65.14 billion (PPP) as of 2017. Lahore is the largest city and historic cultural centre of the wider Punjab region, and is one of Pakistan's most socially liberal, progressive, and cosmopolitan cities.Lahore's origins reach into antiquity. The city has been controlled by numerous empires throughout the course of its history, including the Hindu Shahis, Ghaznavids, Ghurids, and Delhi Sultanate by the medieval era. Lahore reached the height of its splendour under the Mughal Empire between the late 16th and early 18th century, and served as its capital city for a number of years. The city was captured by the forces of the Afsharid ruler Nader Shah in 1739, and fell into a period of decay while being contested between the Afghans and the Sikhs. Lahore eventually became capital of the Sikh Empire in the early 19th century, and regained some of its lost grandeur. Lahore was then annexed to the British Empire, and made capital of British Punjab.

Lahore was central to the independence movements of both India and Pakistan, with the city being the site of both the declaration of Indian Independence, and the resolution calling for the establishment of Pakistan. Lahore experienced some of the worst rioting during the Partition period preceding Pakistan's independence. Following the success of the Pakistan Movement and subsequent independence in 1947, Lahore was declared capital of Pakistan's Punjab province. Lahore exerts a strong cultural influence over Pakistan. Lahore is a major center for Pakistan's publishing industry, and remains the foremost center of Pakistan's literary scene. The city is also a major centre of education in Pakistan, with some of Pakistan's leading universities based in the city. Lahore is also home to Pakistan's film industry, Lollywood, and is a major centre of Qawwali music. The city also hosts much of Pakistan's tourist industry, with major attractions including the Walled City, the famous Badshahi and Wazir Khan mosques and Sikh shrines. Lahore is also home to the Lahore Fort and Shalimar Gardens, both of which are UNESCO World Heritage Sites.
