Salt vs Liverpool

Informations

Salt is a mineral composed primarily of sodium chloride (NaCl), a chemical compound belonging to the larger class of salts; salt in its natural form as a crystalline mineral is known as rock salt or halite. Salt is present in vast quantities in seawater, where it is the main mineral constituent. The open ocean has about 35 grams (1.2 oz) of solids per liter of sea water, a salinity of 3.5%. Salt is essential for life in general, and saltiness is one of the basic human tastes. Salt is one of the oldest and most ubiquitous food seasonings, and salting is an important method of food preservation. Some of the earliest evidence of salt processing dates to around 6,000 BC, when people living in the area of present-day Romania boiled spring water to extract salts; a salt-works in China dates to approximately the same period. Salt was also prized by the ancient Hebrews, the Greeks, the Romans, the Byzantines, the Hittites, Egyptians, and the Indians. Salt became an important article of trade and was transported by boat across the Mediterranean Sea, along specially built salt roads, and across the Sahara on camel caravans. The scarcity and universal need for salt have led nations to go to war over it and use it to raise tax revenues. Salt is used in religious ceremonies and has other cultural and traditional significance.

Salt is processed from salt mines, and by the evaporation of seawater (sea salt) and mineral-rich spring water in shallow pools. Its major industrial products are caustic soda and chlorine; salt is used in many industrial processes including the manufacture of polyvinyl chloride, plastics, paper pulp and many other products. Of the annual global production of around two hundred million tonnes of salt, about 6% is used for human consumption. Other uses include water conditioning processes, de-icing highways, and agricultural use. Edible salt is sold in forms such as sea salt and table salt which usually contains an anti-caking agent and may be iodised to prevent iodine deficiency. As well as its use in cooking and at the table, salt is present in many processed foods. Sodium is an essential nutrient for human health via its role as an electrolyte and osmotic solute. Excessive salt consumption may increase the risk of cardiovascular diseases, such as hypertension, in children and adults. Such health effects of salt have long been studied. Accordingly, numerous world health associations and experts in developed countries recommend reducing consumption of popular salty foods. The World Health Organization recommends that adults should consume less than 2,000 mg of sodium, equivalent to 5 grams of salt per day.

Liverpool is a city and metropolitan borough in Merseyside, England. Its population in 2019 was approximately 498,042, making it the tenth-largest English district by population. Liverpool's metropolitan area is the fifth-largest in the UK with a population of 2.24 million.Liverpool is on the eastern side of the Mersey Estuary and historically lay within the ancient hundred of West Derby in North West England's county of Lancashire. It became a borough in 1207, a city in 1880, and a county borough independent of Lancashire in 1889. Its growth as a major port was paralleled by the expansion of the city throughout the Industrial Revolution. Along with general cargo, freight, and raw materials such as coal and cotton, merchants were involved in the slave trade. In the 19th century, Liverpool was a major port of departure for English and Irish emigrants to North America. It was also home to both the Cunard and White Star Lines, and was the port of registry of the ocean liners RMS Titanic, RMS Lusitania, RMS Queen Mary, and RMS Olympic. In 2019, Liverpool was ranked fifth on the list of the most visited UK cities. It is noted for its culture, architecture, and transport links. The city is closely associated with the arts, especially music; the popularity of the Beatles, who are widely regarded as the most influential musical group in history, cemented the city's status as a tourist destination. Since then, Liverpool has continued to produce many notable musicians and record labels—musicians from the city have produced 56 No. 1 hit singles, more than any other city in the world. It also has a long-standing reputation as the origin of various actors and actresses, artists, athletes, comedians, journalists, novelists, and poets.

The city has the second-highest number of art galleries, national museums, listed buildings, and listed parks in the UK; only the capital, London, has more. The Liverpool Maritime Mercantile City includes the Pier Head, Albert Dock, and William Brown Street. In sports, the city is best known for being the home of Premier League football teams Liverpool FC and Everton FC, with matches between the two being known as the Merseyside derby. The annual Grand National horse race takes place at Aintree Racecourse. Several areas of Liverpool city centre were granted World Heritage Site status by UNESCO in 2004, and the city's vast collection of parks and open spaces has been described as the "most important in the country" by England's Register of Historic Parks and Gardens of Special Historic Interest. Its status as a port city historically attracted a diverse population from a wide range of cultures, primarily Ireland, Norway, and Wales. It is also home to the oldest black community in the UK and the oldest Chinese community in Europe. Natives of Liverpool (and occasionally longtime residents) are formally referred to as "Liverpudlians" but are more often called "Scousers", a reference to the form of stew made popular by sailors in the city, which also became the most common name for the local accent and dialect. The city celebrated its 800th anniversary in 2007 and was named the 2008 European Capital of Culture, which it shared with the Norwegian city of Stavanger. Its designation as European Capital of Culture resulted in a sharp uptick in the city's fortunes, as the money gained from the EU was spent on regenerating large parts of the city that had become run down.
