Salt vs Alexandria

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.

Alexandria ( or ; Arabic: الإسكندرية‎ al-ʾIskandariyya; Egyptian Arabic: اسكندرية‎ Eskendereyya; Coptic: ⲣⲁⲕⲟϯ Rakodī; Greek: Αλεξάνδρεια Alexandria) is the second-largest city in Egypt and a major economic centre. With a population of 5,200,000, Alexandria is the largest city on the Mediterranean - also called the Bride of the Mediterranean by locals - the sixth-largest city in the Arab world and the ninth-largest in Africa. The city extends about 40 km (25 mi) at the northern coast of Egypt along the Mediterranean Sea. Alexandria is a popular tourist destination, and also an important industrial centre because of its natural gas and oil pipelines from Suez. Alexandria was founded in c. 331 BC by Alexander the Great, king of Macedon and leader of the Greek League of Corinth, during his conquest of the Achaemenid Empire. An Egyptian village named Rhacotis existed at the location and grew into the Egyptian quarter of Alexandria. Alexandria grew rapidly to become an important centre of Hellenistic civilization and remained the capital of Ptolemaic Egypt and Roman and Byzantine Egypt for almost 1,000 years, until the Muslim conquest of Egypt in AD 641, when a new capital was founded at Fustat (later absorbed into Cairo).

Hellenistic Alexandria was best known for the Lighthouse of Alexandria (Pharos), one of the Seven Wonders of the Ancient World; its Great Library (the largest in the ancient world); and the Necropolis, one of the Seven Wonders of the Middle Ages. Alexandria was the intellectual and cultural centre of the ancient Mediterranean world for much of the Hellenistic age and late antiquity. It was at one time the largest city in the ancient world before being eventually overtaken by Rome. The city was a major centre of early Christianity and was the centre of the Patriarchate of Alexandria, which was one of the major centres of Christianity in the Eastern Roman Empire. In the modern world, the Coptic Orthodox Church and the Greek Orthodox Church of Alexandria both lay claim to this ancient heritage. By the time of the Arab conquest of Egypt in 641 AD, the city had already been largely plundered and lost its significance before re-emerging in the modern era. From the late 18th century, Alexandria became a major centre of the international shipping industry and one of the most important trading centres in the world, both because it profited from the easy overland connection between the Mediterranean Sea and the Red Sea, and the lucrative trade in Egyptian cotton.
