Salt vs Łódź

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.

Łódź (Polish: [wutɕ] (listen)), written in English as Lodz, is the third-largest city in Poland and a former industrial centre. Located in the central part of the country, it has a population of 679,941 (2019). It is the capital of Łódź Voivodeship, and is located approximately 120 kilometres (75 mi) south-west of Warsaw. The city's coat of arms is an example of canting, as it depicts a boat (łódź in Polish), which alludes to the city's name. Łódź was once a small settlement that first appeared in 14th-century records. Despite being granted town rights in 1423, it remained the private property of the Kuyavian bishops and clergy until the late 18th century. The Second Industrial Revolution brought rapid growth in textile manufacturing and in population due to the inflow of migrants, notably Germans and Jews. Ever since the industrialization of the area, the city has struggled with multinationalism and social inequalities, which were documented in the novel The Promised Land by Nobel Prize-winning author Władysław Reymont. The contrasts greatly reflected on the architecture of the city, where luxurious mansions coexisted with redbrick factories and dilapidated tenement houses.

The industrial development and demographic surge made Łódź one of the largest cities in Poland. Under the German occupation during World War II, Łódź was briefly renamed to Litzmannstadt in honour of Karl Litzmann. The city's large Jewish population was forced into a walled zone known as the Łódź Ghetto, from which they were sent to German concentration and extermination camps. The city itself sustained insignificant damage during the war and became Poland's temporary seat of power in 1945. Łódź experienced a sharp demographic and economic decline after 1989. It was only in the 2010s that the city began to experience revitalization of its neglected downtown area. Łódź is ranked by the Globalization and World Cities Research Network on the “Sufficiency” level of global influence and is internationally known for its National Film School, a cradle for the most renowned Polish actors and directors, including Andrzej Wajda and Roman Polanski. In 2017, the city was inducted into the UNESCO Creative Cities Network and named UNESCO City of Film.
