62-426: A blockade is the act of actively preventing a country or region from receiving or sending out food , supplies , weapons , or communications , and sometimes people, by military force . A blockade differs from an embargo or sanction , which are legal barriers to trade rather than physical barriers. It is also distinct from a siege in that a blockade is usually directed at an entire country or region, rather than

124-714: A Greek Christian, known as George of Antioch , who previously had served as a naval commander for several North African Muslim rulers. Roger styled George in Abbasid fashion as Amir of Amirs , or Amīr al-Umarāʾ, with the title becoming Latinized in the 13th century as ammiratus ammiratorum . The Sicilians and later the Genoese took the first two parts of the term from their Aragon opponents and used them as one word, amiral . . The French gave their sea commanders similar titles while in Portuguese and Spanish

186-427: A blockaded area of water, but any ship can be inspected as soon as it is established that it is attempting to break the blockade. This inspection can occur inside the blockaded area or in international waters, but never inside the territorial waters of a neutral nation . A neutral ship must obey a request to stop for inspection from the blockading nation. If the situation so demands, the blockading nation can request that

248-490: A blockaded area. It has mainly been done by ships (called blockade runners ) across ports under naval blockade. Blockade runners were typically the fastest ships available and often lightly armed and armored. It is now also been done by aircraft, forming airbridges , such as over the Berlin Blockade after World War II . Food Food is any substance consumed by an organism for nutritional support. Food

310-743: A diverse range of species from annelids to elephants, chimpanzees and many birds. About 182 fish consume seeds or fruit. Animals (domesticated and wild) use as many types of grasses that have adapted to different locations as their main source of nutrients. Humans eat thousands of plant species; there may be as many as 75,000 edible species of angiosperms , of which perhaps 7,000 are often eaten. Plants can be processed into breads, pasta, cereals, juices and jams or raw ingredients such as sugar, herbs, spices and oils can be extracted. Oilseeds are pressed to produce rich oils – ⁣ sunflower , flaxseed , rapeseed (including canola oil ) and sesame . Many plants and animals have coevolved in such

372-465: A fortress or city and the objective may not always be to conquer the area. A blockading power can seek to cut off all maritime transport from and to the blockaded country, although stopping all land transport to and from an area may also be considered a blockade. Blockades restrict the trading rights of neutrals, who must submit for inspection for contraband, which the blockading power may define narrowly or broadly, sometimes including food and medicine. In

434-583: A high protein, fibre, vitamin E and B content. Seeds are a good source of food for animals because they are abundant and contain fibre and healthful fats, such as omega-3 fats . Complicated chemical interactions can enhance or depress bioavailability of certain nutrients. Phytates can prevent the release of some sugars and vitamins. Animals that only eat plants are called herbivores , with those that mostly just eat fruits known as frugivores , leaves, while shoot eaters are folivores (pandas) and wood eaters termed xylophages (termites). Frugivores include

496-549: A military target. In such case, they are a war crime and potentially a crime against humanity . Although primitive naval blockades had been in use for millennia, they were limited by the time ships were able to stay at sea uninterruptedly. The first successful attempts at establishing a full naval blockade were made by the British Royal Navy during the Seven Years' War (1754–1763) against France . Following

558-678: A million. Herbivores generally have more than carnivores as they need to tell which plants may be poisonous. Not all mammals share the same tastes: some rodents can taste starch , cats cannot taste sweetness, and several carnivores (including hyenas , dolphins, and sea lions) have lost the ability to sense up to four of the five taste modalities found in humans. Food is broken into nutrient components through digestive process. Proper digestion consists of mechanical processes ( chewing , peristalsis ) and chemical processes ( digestive enzymes and microorganisms ). The digestive systems of herbivores and carnivores are very different as plant matter

620-469: A news article published by an Arabic news outlet: On 24 May 2012, in a change of command ceremony aboard aircraft carrier USS Enterprise (CVN 65) , while docked at Khalifa Bin Salman Port, Bahrain , U.S. Marine Corps Gen . James Mattis , Commander, U.S. Central Command , introduced Vice Admiral Mark I. Fox as "Admiral Fox, the prince of the sea, emir of the sea – to translate 'admiral' from

682-546: A source of food for protozoa, who in turn provide a source of food for other organisms such as small invertebrates. Other organisms that feed on bacteria include nematodes, fan worms, shellfish and a species of snail. In the marine environment, plankton (which includes bacteria , archaea , algae , protozoa and microscopic fungi ) provide a crucial source of food to many small and large aquatic organisms. Without bacteria, life would scarcely exist because bacteria convert atmospheric nitrogen into nutritious ammonia . Ammonia

744-556: A specific ecological niche within specific geographical contexts. Omnivorous humans are highly adaptable and have adapted to obtain food in many different ecosystems. Humans generally use cooking to prepare food for consumption. The majority of the food energy required is supplied by the industrial food industry , which produces food through intensive agriculture and distributes it through complex food processing and food distribution systems. This system of conventional agriculture relies heavily on fossil fuels , which means that

806-425: A system with nineteen food classifications: cereals, roots, pulses and nuts, milk, eggs, fish and shellfish, meat, insects, vegetables, fruits, fats and oils, sweets and sugars, spices and condiments, beverages, foods for nutritional uses, food additives, composite dishes and savoury snacks. In a given ecosystem, food forms a web of interlocking chains with primary producers at the bottom and apex predators at

868-456: A way that the fruit is a good source of nutrition to the animal who then excretes the seeds some distance away, allowing greater dispersal. Even seed predation can be mutually beneficial, as some seeds can survive the digestion process. Insects are major eaters of seeds, with ants being the only real seed dispersers. Birds, although being major dispersers, only rarely eat seeds as a source of food and can be identified by their thick beak that

930-447: Is a fruit if the part eaten is derived from the reproductive tissue , so seeds, nuts and grains are technically fruit. From a culinary perspective, fruits are generally considered the remains of botanically described fruits after grains, nuts, seeds and fruits used as vegetables are removed. Grains can be defined as seeds that humans eat or harvest, with cereal grains (oats, wheat, rice, corn, barley, rye, sorghum and millet) belonging to

992-696: Is a sensation considered unpleasant characterised by having a sharp, pungent taste. Unsweetened dark chocolate, caffeine , lemon rind, and some types of fruit are known to be bitter. Umami, commonly described as savory, is a marker of proteins and characteristic of broths and cooked meats. Foods that have a strong umami flavor include cheese, meat and mushrooms. While most animals taste buds are located in their mouth, some insects taste receptors are located on their legs and some fish have taste buds along their entire body. Dogs, cats and birds have relatively few taste buds (chickens have about 30), adult humans have between 2000 and 4000, while catfish can have more than

1054-402: Is caused by acids , such as vinegar in alcoholic beverages. Sour foods include citrus, specifically lemons and limes . Sour is evolutionarily significant as it can signal a food that may have gone rancid due to bacteria. Saltiness is the taste of alkali metal ions such as sodium and potassium. It is found in almost every food in low to moderate proportions to enhance flavor. Bitter taste

1116-731: Is drunk or processed into dairy products (cheese, butter, etc.). Eggs laid by birds and other animals are eaten and bees produce honey , a reduced nectar from flowers that is used as a popular sweetener in many cultures. Some cultures consume blood , such as in blood sausage , as a thickener for sauces, or in a cured , salted form for times of food scarcity, and others use blood in stews such as jugged hare . Animals, specifically humans, typically have five different types of tastes: sweet , sour , salty , bitter , and umami . The differing tastes are important for distinguishing between foods that are nutritionally beneficial and those which may contain harmful toxins. As animals have evolved ,

1178-662: Is expressly defined as "of the sea, Lat. marinus, epith. of sea-gods , nymphs , etc." Though there are multiple meanings for the Arabic Amīr (أمير), the literal meaning of the phrase Amīr al-Baḥr (أمير البحر) is "Prince of the Sea." This position, versus "commander of the sea," is demonstrated by legal practices prevailing in the Ottoman Empire , whereas it was only possible for Phanariots to qualify for attaining four princely positions, those being grand dragoman , dragoman of

1240-502: Is harder to digest. Carnivores mouths are designed for tearing and biting compared to the grinding action found in herbivores. Herbivores however have comparatively longer digestive tracts and larger stomachs to aid in digesting the cellulose in plants. According to the World Health Organization (WHO), about 600 million people worldwide get sick and 420,000 die each year from eating contaminated food. Diarrhea

1302-406: Is mainly composed of water, lipids , proteins , and carbohydrates . Minerals (e.g., salts) and organic substances (e.g., vitamins ) can also be found in food. Plants, algae , and some microorganisms use photosynthesis to make some of their own nutrients. Water is found in many foods and has been defined as a food by itself. Water and fiber have low energy densities, or calories , while fat

1364-531: Is pronounced "naúarkhēs," existed from very ancient times in Greece. While ναύαρχος may be defined as "admiral" as used by Plutarch in his Parallel Lives , the very pronunciation of ναύαρχος demonstrates that it is not a part of the etymology for the English word "admiral." The word "admiral" has come to be almost exclusively associated with the highest naval rank in most of the world's navies , equivalent to

1426-506: Is the most common illness caused by consuming contaminated food, with about 550 million cases and 230,000 deaths from diarrhea each year. Children under five years of age account for 40% of the burden of foodborne illness, with 125,000 deaths each year. A 2003 World Health Organization (WHO) report concluded that about 30% of reported food poisoning outbreaks in the WHO European Region occur in private homes. According to

1488-738: Is the most energy-dense component. Some inorganic (non-food) elements are also essential for plant and animal functioning. Human food can be classified in various ways, either by related content or by how it is processed. The number and composition of food groups can vary. Most systems include four basic groups that describe their origin and relative nutritional function: Vegetables and Fruit, Cereals and Bread, Dairy, and Meat. Studies that look into diet quality group food into whole grains/cereals, refined grains/cereals, vegetables, fruits, nuts, legumes, eggs, dairy products, fish, red meat, processed meat, and sugar-sweetened beverages. The Food and Agriculture Organization and World Health Organization use

1550-565: Is the precursor to proteins, nucleic acids, and most vitamins. Since the advent of industrial process for nitrogen fixation, the Haber-Bosch Process , the majority of ammonia in the world is human-made. Plants as a food source are divided into seeds, fruits, vegetables, legumes, grains and nuts. Where plants fall within these categories can vary, with botanically described fruits such as the tomato, squash, pepper and eggplant or seeds like peas commonly considered vegetables. Food

1612-402: Is then released, and the glucose stored as an energy reserve. Photosynthetic plants, algae and certain bacteria often represent the lowest point of the food chains, making photosynthesis the primary source of energy and food for nearly all life on earth. Plants also absorb important nutrients and minerals from the air, natural waters, and soil. Carbon, oxygen and hydrogen are absorbed from

1674-406: Is used to crack open the seed coat. Mammals eat a more diverse range of seeds, as they are able to crush harder and larger seeds with their teeth. Animals are used as food either directly or indirectly. This includes meat, eggs, shellfish and dairy products like milk and cheese. They are an important source of protein and are considered complete proteins for human consumption as they contain all

1736-428: Is usually of plant, animal, or fungal origin and contains essential nutrients such as carbohydrates , fats , proteins , vitamins , or minerals . The substance is ingested by an organism and assimilated by the organism's cells to provide energy, maintain life, or stimulate growth. Different species of animals have different feeding behaviours that satisfy the needs of their metabolisms and have evolved to fill

1798-515: The Arabic amīral ( أمير الـ ) – amīr ( أمير ) [ʔmjr] ( listen ), " king , prince , chief, leader, nobleman , lord , a governor , commander , or person who rules over a number of people" and al ( الـ ), the Arabic definite article meaning "the." In Arabic, admiral is also represented as Amīr al-Baḥr ( أمير البحر ), where al-Baḥr (البحر) means the sea . The 1818 edition of Samuel Johnson 's A Dictionary of

1860-631: The Battle of Trafalgar . Until 1827, blockades, as part of economic warfare , were always a part of a war. This changed when France, Russia and Britain came to the aid of the Greek rebels against Turkey . They blockaded the Turkish-occupied coast, which led to the battle of Navarino . War was never declared, however, so it is considered the first pacific — i.e. peaceful — blockade. The first truly pacific blockade , involving no shooting at all,

1922-785: The International Association for Food Protection , the World Resources Institute , the World Food Programme , the Food and Agriculture Organization , and the International Food Information Council . Food is any substance consumed to provide nutritional support and energy to an organism . It can be raw, processed, or formulated and is consumed orally by animals for growth, health, or pleasure.

1984-750: The Poaceae (grass) family and pulses coming from the Fabaceae (legume) family. Whole grains are foods that contain all the elements of the original seed (bran, germ, and endosperm ). Nuts are dry fruits, distinguishable by their woody shell. Fleshy fruits (distinguishable from dry fruits like grain, seeds and nuts) can be further classified as stone fruits (cherries and peaches), pome fruits (apples, pears), berries (blackberry, strawberry), citrus (oranges, lemon), melons (watermelon, cantaloupe), Mediterranean fruits (grapes, fig), tropical fruits (banana, pineapple). Vegetables refer to any other part of

2046-571: The 20th century, air power has also been used to enhance the effectiveness of blockades by halting air traffic within the blockaded airspace. Close patrol of hostile ports, in order to prevent naval forces from putting to sea, is also referred to as a blockade. When coastal cities or fortresses were besieged from the landward side, the besiegers would often blockade the seaward side as well. Most recently, blockades have sometimes included cutting off electronic communications by jamming radio signals and severing undersea cables . Blockades often result in

2108-509: The Arabic to English;" On 04 Feb 2021, in an announcement of his coronavirus -related death, the Arabic news website Saudi 24 News referred to Admiral Edmond Chagoury by the title "Prince of the Sea." One alternate etymology proposes that the term admiral evolved, instead, from the title of Amīr al-Umarā ʾ (أمير الأمراء). Under the reign of the Buyid dynasty (934 to 1062) of Iraq and Iran ,

2170-610: The British naval victory at Quiberon Bay , which ended any immediate threat of a major invasion of Britain , Britain established a close blockade on the French coast. This starved French ports of commerce, weakening France's economy. Admiral Edward Hawke took command of the blockading fleet off Brest and extended the blockade to cover the entire French Atlantic coast from Dunkirk to Bordeaux , and also to Marseilles on France's Mediterranean coast. The strategic importance of blockade

2232-674: The English Language , edited and revised by the Rev. Henry John Todd , states that the term "has been traced to the Arab. emir or amir, lord or commander, and the Gr . ἄλιος , the sea, q. d. prince of the sea . The word is written both with and without the d, in other languages, as well as our own. Barb. Lat. admirallus and amiralius. V. Ducange. Barb. Græc. ἄμηρχλιος. V. Meursii Gloss.

According to the not ratified document San Remo Manual on International Law Applicable to Armed Conflicts at Sea, 12 June 1994, a blockade is a legal method of warfare at sea but is governed by rules. The manual describes what can never be contraband. The blockading nation is free to select anything else as contraband in a list, which it must publish. The blockading nation typically establishes

2356-721: The WHO and CDC , in the USA alone, annually, there are 76 million cases of foodborne illness leading to 325,000 hospitalizations and 5,000 deaths. From 2011 to 2016, on average, there were 668,673 cases of foodborne illness and 21 deaths each year. In addition, during this period, 1,007 food poisoning outbreaks with 30,395 cases of food poisoning were reported. Admiral The word admiral in Middle English comes from Anglo-French amiral , "commander", from Medieval Latin admiralis , admirallus . These evolved from

The three main nutrients absorbed from the soil for plant growth are nitrogen, phosphorus and potassium, with other important nutrients including calcium, sulfur, magnesium, iron boron, chlorine, manganese, zinc, copper molybdenum and nickel. Bacteria and other microorganisms also form the lower rungs of the food chain. They obtain their energy from photosynthesis or by breaking down dead organisms, waste or chemical compounds. Some form symbiotic relationships with other organisms to obtain their nutrients. Bacteria provide

2480-440: The apex predators, the animals that have no known predators in its ecosystem. Humans are considered apex predators. Humans are omnivores, finding sustenance in vegetables, fruits, cooked meat, milk, eggs, mushrooms and seaweed. Cereal grain is a staple food that provides more food energy worldwide than any other type of crop. Corn (maize) , wheat, and rice account for 87% of all grain production worldwide. Just over half of

2542-416: The army rank of general . However, this was not always the case; for example, in some European countries prior to the end of World War II , admiral was the third highest naval rank after general admiral and grand admiral . The rank of admiral has also been subdivided into various grades, several of which are historically extinct while others remain in use in most present-day navies. The Royal Navy used

2604-476: The colours red, white, and blue, in descending order to indicate seniority of its admirals until 1864; for example, Horatio Nelson 's highest rank was vice-admiral of the white. The generic term for these naval equivalents of army generals is flag officer . Some navies have also used army-type titles for them, such as the Cromwellian "general at sea". While the rank is used in most of NATO countries, it

2666-555: The definition of Amīr (أمير), as given in Edward William Lane 's Arabic-English Lexicon , concurs, in part, with Minsheu's definition, stating that the term means "One having, holding, or possessing, command; a commander; a governor; a lord; a prince, or king." While other Greek words of the period existed to indicate "belonging to the sea," or "of the sea," the now obsolete Gr. ἄλιος mentioned in Johnson's Dictionary

2728-567: The essential amino acids that the human body needs. One 4-ounce (110 g) steak, chicken breast or pork chop contains about 30 grams of protein. One large egg has 7 grams of protein. A 4-ounce (110 g) serving of cheese has about 15 grams of protein. And 1 cup of milk has about 8 grams of protein. Other nutrients found in animal products include calories, fat, essential vitamins (including B12) and minerals (including zinc, iron, calcium, magnesium). Food products produced by animals include milk produced by mammary glands , which in many cultures

2790-599: The fleet , and the voivodees of Moldavia and Wallachia . Those Phanariots who attained the princely position of dragoman of the fleet served under the Ottoman admiral having administration of the Aegean islands and the Anatolian coast. Modern acknowledgement of the phrase Amīr -al-Baḥr (أمير البحر) meaning "Prince of the Sea" includes a speech made in an official U.S. military ceremony conducted in an Arabic port, and

2852-447: The food and agricultural systems are one of the major contributors to climate change , accounting for as much as 37% of total greenhouse gas emissions . The food system has significant impacts on a wide range of other social and political issues, including sustainability , biological diversity , economics , population growth , water supply , and food security . Food safety and security are monitored by international agencies like

2914-550: The form of starch, fructose, glucose and other sugars. Most vitamins are found from plant sources, with exceptions of vitamin D and vitamin B 12 . Minerals can also be plentiful or not. Fruit can consist of up to 90% water, contain high levels of simple sugars that contribute to their sweet taste, and have a high vitamin C content. Compared to fleshy fruit (excepting Bananas) vegetables are high in starch, potassium , dietary fiber, folate and vitamins and low in fat and calories. Grains are more starch based and nuts have

2976-587: The most difficult form of blockade to implement. Difficulties arise because the blockading ships must remain continuously at sea, exposed to storms and hardship, usually far from any support, and vulnerable to sudden attack from the blockaded side, whose ships may stay safe in harbor until they choose to come out. In a distant blockade, the blockaders stay well away from the blockaded coast and try to intercept any ships going in or out. This may require more ships on station, but they can usually operate closer to their bases, and are at much less risk from enemy raids. This

3038-413: The plant that can be eaten, including roots, stems, leaves, flowers, bark or the entire plant itself. These include root vegetables (potatoes and carrots), bulbs (onion family), flowers (cauliflower and broccoli), leaf vegetables ( spinach and lettuce) and stem vegetables (celery and asparagus ). The carbohydrate, protein and lipid content of plants is highly variable. Carbohydrates are mainly in

3100-527: The same. Germ. ammiral. Dutch, admirael or ammirael. Ital. ammiraglio. Sp. almirante. Minsheu, in his Spanish Dictionary, says 'almiralle is a king in the Arabian language.' Amrayl is used by Robert of Gloucester, in the sense of a prince, or governour." The quote from John Minsheu 's Dictionarie in Spanish and English (1599), given in Johnson's Dictionary, has been confirmed as being accurate. Additionally,

3162-483: The ship divert to a known place or harbour for inspection. If the ship does not stop, then the ship is subject to capture. If people aboard the ship resist capture, they can be lawfully attacked. Whether or not a blockade was seen as lawful depended on the laws of the nations whose trade was influenced by the blockade. The Brazilian blockade of Río de la Plata in 1826 during the Cisplatine War , for instance,

3224-477: The starvation of the civilian population, notably during the blockade of Germany during World War I and the blockade of Biafra during the Nigerian Civil War . According to modern international law, blockades are an act of war. When used as a part of an effort to starve the civilian population, they are illegal as part of a war of aggression or when used against a civilian population, instead of

3286-448: The tastes that provide the most energy are the most pleasant to eat while others are not enjoyable, although humans in particular can acquire a preference for some substances which are initially unenjoyable. Water, while important for survival, has no taste. Sweetness is almost always caused by a type of simple sugar such as glucose or fructose , or disaccharides such as sucrose , a molecule combining glucose and fructose. Sourness

3348-631: The title of Amīr al-Umarāʾ, which means prince of princes, came to denote the heir-apparent , or crown prince . This alternate etymology states that the term was in use for the Greco-Arab naval leaders (e.g. Christodulus ) in the Norman-Arab-Byzantine culture of Norman Sicily , which had formerly been ruled by Arabs, at least by the early 11th century. During this time, the Norman Roger II of Sicily (1095–1154) employed

3410-523: The top. Other aspects of the web include detrovores (that eat detritis ) and decomposers (that break down dead organisms). Primary producers include algae, plants, bacteria and protists that acquire their energy from sunlight. Primary consumers are the herbivores that consume the plants, and secondary consumers are the carnivores that consume those herbivores. Some organisms, including most mammals and birds, diet consists of both animals and plants, and they are considered omnivores. The chain ends with

3472-510: The word changed to almirante . As the word was used by people speaking Latin or Latin-based languages it gained the "d" and endured a series of different endings and spellings leading to the English spelling admyrall in the 14th century and to admiral by the 16th century. It is important to note that the etymology of a word does not suggest the antiquity of the word as it may have appeared in other languages with entirely different pronunciations. The Greek ναύαρχος, for instance, which

3534-403: The world's crops are used to feed humans (55 percent), with 36 percent grown as animal feed and 9 percent for biofuels . Fungi and bacteria are also used in the preparation of fermented foods like bread , wine , cheese and yogurt . During photosynthesis , energy from the sun is absorbed and used to transform water and carbon dioxide in the air or soil into oxygen and glucose. The oxygen

3596-505: Was almost impossible prior to the 16th century due to the nature of the ships used. A loose blockade is a close blockade where the blockading ships are withdrawn out of sight from the coast (behind the horizon) but no farther. The object of loose blockade is to lure the enemy into venturing out but to stay close enough to strike. British admiral Horatio Nelson applied a loose blockade at Cádiz in 1805. The Franco-Spanish fleet under Pierre-Charles Villeneuve then came out, resulting in

3658-412: Was considered lawful according to British law but unlawful according to French and American law. The latter two countries announced they would actively defend their ships against Brazilian blockaders, while Britain was forced to steer for a peaceful solution between Brazil and Argentina . Blockades depend on four general factors Blockade running is the practice of delivering cargo (food, for example) to

3720-459: Was repeated in World War II . Naval strategic thinkers, such as Sir Julian Corbett and Alfred Thayer Mahan , wrote that naval conflicts were won primarily by decisive battles, but also by blockade. A close blockade entails placing warships within sight of the blockaded coast or port, to ensure the immediate interception of any ship entering or leaving. It is both the most effective and

3782-853: Was shown during the French Revolutionary Wars and Napoleonic Wars , when the Royal Navy successfully blockaded France, leading to major economic disruptions. The Union blockade of southern ports was a major factor in the American Civil War . During World War I , the Allies blockaded the Central Powers , depriving them of food and other strategic materials. Germany's attempted U-boat blockade caused some shortages in Britain, but ultimately failed. This outcome
