Salt vs La D

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.

Fiorello Henry La Guardia (; born Fiorello Raffaele Enrico La Guardia, Italian pronunciation: [fjoˈrɛllo raf.faˈɛ.le enˈriːko la ˈɡwardja]; December 11, 1882 – September 20, 1947) was an American attorney and politician who represented New York in the House of Representatives and served as the 99th Mayor of New York City from 1934 to 1946. He was known for his irascible, energetic, and charismatic personality and diminutive, rotund stature. A socialist member of the Republican Party, La Guardia was frequently cross-endorsed by parties other than his own, especially parties on the left under New York's electoral fusion laws. A panel of 69 scholars in 1993 ranked him first among the ten best mayors in American history. He was born to Italian immigrants in New York City. Before serving as mayor, La Guardia represented Manhattan in Congress and on the New York City Board of Aldermen. As mayor, during the Great Depression and World War II, La Guardia unified the city's transit system; expanded construction of public housing, playgrounds, parks, and airports; reorganized the New York Police Department; and implemented federal New Deal programs within the city.

He pursued a long series of political reforms, curbing the power of the powerful Irish-controlled Tammany Hall political machine that controlled the Democratic Party in Manhattan. He also re-established merit-based employment and promotion within city administration. La Guardia was also a highly visible national political figure. His support for the New Deal and relationship with President Franklin D. Roosevelt crossed party lines, brought federal funds to New York City, and cut off patronage to La Guardia's Tammany enemies. La Guardia's WNYC radio program "Talk to the People", which aired from December 1941 until December 1945, expanded his public influence beyond the borders of the city.
