North Africa

North Africa or Northern Africa is the northernmost region of Africa. Geopolitically, the United Nations definition of Northern Africa includes seven countries and territories; Algeria, Egypt, Libya, Morocco, Sudan, Tunisia, and Western Sahara. Algeria, Morocco, Tunisia, Libya, often Mauritania and Western Sahara form the Maghreb, while Egypt and Sudan comprise the Nile Valley (so named after the Nile River, which has two tributaries; the White Nile and Blue Nile). Egypt is a transcontinental country because of the Sinai Peninsula, which geographically lies in West Asia. North Africa also includes a number of Spanish possessions (Ceuta and Melilla and tiny Spanish islets off the coast of Morocco). The Canary Islands and the Portuguese Madeira Islands, in the North Atlantic Ocean northwest of the African mainland, are sometimes included in considerations of the region.

The distinction between North Africa and much of Sub-Saharan Africa is historically and ecologically significant because of the effective barrier created by the Sahara Desert for much of modern history. From 3500 BC, following the abrupt desertification of the Sahara due to gradual changes in the Earth's orbit, this barrier has culturally separated the North from the rest of the continent. As the seafaring civilizations of the Phoenicians, Greeks, Romans, Muslims and others facilitated communication and migration across the Mediterranean Sea, the cultures of North Africa became much more closely tied to Southwestern Asia and Europe than Sub-Saharan Africa. The Islamic influence in the area is also significant, and North Africa is a major part of the Islamic world.

Bear Grylls

Edward Michael "Bear" Grylls (born 7 June 1974) is a British adventurer, writer and television presenter. He is widely known for his television series Man vs. Wild (2006–2011), originally titled Born Survivor: Bear Grylls in the United Kingdom.

Personal life

Grylls was born in Donaghadee, County Down, Northern Ireland. He grew up in Donaghadee until the age of four, when his family moved to Bembridge on the Isle of Wight.

He is the son of Conservative politician Sir Michael Grylls, who was implicated in the cash-for-questions affair, and Lady Sarah Grylls. Lady Grylls is the daughter of politician Patricia Ford, briefly an Ulster Unionist Party MP, and cricketer and businessman Neville Ford. Grylls has one sibling, an elder sister, Lara Fawcett, a cardio-tennis coach, who gave him the nickname 'Bear' when he was a week old.

North

North is a noun, adjective, or adverb indicating direction or geography. North is one of the four cardinal directions or compass points. It is the opposite of south and is perpendicular to east and west.

Etymology

The word north is related to the Old High German nord, both descending from the Proto-Indo-European unit ner-, meaning "down" (or "under"). (Presumably a natural primitive description of its concept is "to the left of the rising sun".)

The Latin word borealis comes from the Greek boreas "north wind, north", which, according to Ovid, was personified as the son of the river-god Strymon, the father of Calais and Zetes. Septentrionalis is from septentriones, "the seven plow oxen", a name of Ursa Maior. The Greek arktikos is named for the same constellation, and is the derivation of the English word "Arctic".

Other languages have sometimes more interesting derivations. For example, in Lezgian, kefer can mean both 'disbelief' and 'north', since to the north of the Muslim Lezgian homeland there are areas formerly inhabited by non-Muslim Caucasian and Turkic peoples. In many languages of Mesoamerica, "north" also means "up". In Hungarian the word for north is észak, which is derived from éjszaka ("night"), since above the Tropic of Cancer, the Sun never shines from the north.

Africa

Africa is the world's second-largest and second-most-populous continent. At about 30.2 million km² (11.7 million sq mi) including adjacent islands, it covers six percent of Earth's total surface area and 20.4 percent of its total land area. With 1.1 billion people as of 2013, it accounts for about 15% of the world's human population. The continent is surrounded by the Mediterranean Sea to the north, both the Suez Canal and the Red Sea along the Sinai Peninsula to the northeast, the Indian Ocean to the southeast, and the Atlantic Ocean to the west. The continent includes Madagascar and various archipelagos. It contains 54 fully recognized sovereign states (countries), nine territories and two de facto independent states with limited or no recognition.

Africa's population is the youngest amongst all the continents; the median age in 2012 was 19.7, when the worldwide median age was 30.4.Algeria is Africa's largest country by area, and Nigeria by population. Africa, particularly central Eastern Africa, is widely accepted as the place of origin of humans and the Hominidae clade (great apes), as evidenced by the discovery of the earliest hominids and their ancestors, as well as later ones that have been dated to around seven million years ago, including Sahelanthropus tchadensis, Australopithecus africanus, A. afarensis, Homo erectus, H. habilis and H. ergaster – with the earliest Homo sapiens (modern human) found in Ethiopia being dated to circa 200,000 years ago. Africa straddles the equator and encompasses numerous climate areas; it is the only continent to stretch from the northern temperate to southern temperate zones.
