Salt vs Katowice

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.

Katowice (UK: KAT-ə-VEET-sə, US: KAHT-, Polish: [katɔˈvitsɛ] (listen); Silesian: Katowicy; German: Kattowitz) is a city in southern Poland, the capital city of the Silesian Region, and a center of the Upper Silesia and Dąbrowa Basin Metropolis. With the population of 292,774 (as of 2019), it is the eleventh-largest city in Poland. The wider Katowice urban area has the population of approximately 2 to 3 million people. Throughout the mid-18th century, Katowice had developed into a village upon the discovery of rich coal reserves in the area. In 1742 the First Silesian War transferred Upper Silesia, including Katowice, to Prussia. Subsequently, from the second half of the 18th century, many German or Prussian craftsmen, merchants and artists began to settle in the region, which had been inhabited mostly by Poles over the past hundreds of years. Simultaneously Silesia experienced the influx of the first Jewish settlers. In the first half of the 19th century, intensive industrialization transformed local mills and farms into industrial steelworks, mines, foundries and artisan workshops. This also contributed to the establishment of companies and eventual rapid growth of the city. At the same time, Katowice became linked to the railway system with the first train arriving at the main station in 1847.The outbreak of World War I was favourable for Katowice due to the prospering steel industry. Following Germany's defeat and the Silesian uprisings, Katowice and parts of Upper Silesia were annexed by the Second Polish Republic. Poland was then backed by the Geneva Convention and the ethnic Silesian minority.

On 3 May 1921, the Polish army entered Katowice and the Polish administration took control. The city became the capital of the autonomous Silesian Voivodeship as well as the seat of the Silesian Parliament and Committee of Upper Silesia. After the plebiscite, many former German citizens emigrated; however, a vibrant German community remained until the end of World War II. In 1939, after the Wehrmacht seized the town, Katowice and the provinces were incorporated into the Third Reich. The town was eventually liberated by the Soviet army on 27 January 1945.Katowice is a center of science, culture, industry, business, trade, and transportation in Upper Silesia and southern Poland, and the main city in the Upper Silesian Industrial Region. Katowice lies within an urban zone, with a population of 2,746,460 according to Eurostat, and also part of the wider Silesian metropolitan area, with a population of 5,008,000 according to the Brookings Institution or 5,294,000 according to the European Spatial Planning Observation Network.In 2020, the city is classified as a Gamma - global city by the Globalization and World Cities Research Network and is considered as an emerging metropolis. The whole metropolitan area is the 16th most economically powerful city by GDP in the European Union with an output amounting to $114.5 billion.Katowice is the seat of the Polish National Radio Symphony and Orchestra. It also hosts the finals of Intel Extreme Masters, an Esports video game tournament. In 2015, Katowice joined the UNESCO Creative Cities Network and was named a UNESCO City of Music.
