Leipzig vs Salt

Informations

Leipzig (, also , , German: [ˈlaɪptsɪç] (listen); Upper Saxon: Leibz'sch) is the most populous city in the German state of Saxony. With a population of 600,000 inhabitants as of 2019 (1.1 million residents in the larger urban zone), it is Germany's eighth most populous city as well as the second most populous city in the area of former East Germany after (East) Berlin. Together with Halle (Saale), the largest city of the neighbouring state of Saxony-Anhalt, the city forms the polycentric conurbation of Leipzig-Halle. Between the two cities (in Schkeuditz) lies Leipzig/Halle Airport. Leipzig is located about 160 kilometres (99 mi) southwest of Berlin in the Leipzig Bay, which constitutes the southernmost part of the North German Plain, at the confluence of the White Elster River (progression: Saale→ Elbe→ North Sea) and two of its tributaries: the Pleiße and the Parthe. The name of the city as well as the names of many of its boroughs are of Slavic origin. Leipzig has been a trade city since at least the time of the Holy Roman Empire. The city sits at the intersection of the Via Regia and the Via Imperii, two important medieval trade routes. Leipzig was once one of the major European centres of learning and culture in fields such as music and publishing. After the Second World War and during the period of the German Democratic Republic (East Germany) Leipzig remained a major urban centre in East Germany, but its cultural and economic importance declined. Events in Leipzig in 1989 played a significant role in precipitating the fall of communism in Central and Eastern Europe, mainly through demonstrations starting from St. Nicholas Church. The immediate effects of the reunification of Germany included the collapse of the local economy, which had come to depend on highly polluting heavy industry, severe unemployment, and urban blight.

Starting around 2000, however, the decline was first arrested and then reversed and, since then, Leipzig has seen significant changes with the restoration of major historical buildings, the demolition of derelict properties of little historical value, and the development of new industries and a modern transport infrastructure.Leipzig today is an economic centre, is rated as the most livable city in Germany by the GfK marketing research institution, and has the second-best future prospects of all cities in Germany according to HWWI and Berenberg Bank. The city is one of two seats of the German National Library, as well as the seat of the German Federal Administrative Court. Leipzig Zoo is one of the most modern zoos in Europe and ranks first in Germany and second in Europe. Since the opening of the Leipzig City Tunnel in 2013, Leipzig forms the centrepiece of the S-Bahn Mitteldeutschland public transit system. Leipzig is currently listed as a "Sufficiency" level global city by the Globalization and World Cities Research Network, Germany's "Boomtown" and was the 2019 European City of the Year.Leipzig has long been a major centre for music, both classical as well as modern "dark alternative music" or darkwave genres. The Oper Leipzig is one of the most prominent opera houses in Germany. Leipzig is also home to the University of Music and Theatre "Felix Mendelssohn Bartholdy". The Leipzig Gewandhaus Orchestra, established in 1743, is one of the oldest symphony orchestras in the world. Johann Sebastian Bach is one among many major composers who lived and worked in Leipzig and, during a stay in the city, Friedrich Schiller wrote his poem "Ode to Joy".

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.
