The World Portal
The world is the totality of entities, the whole of reality, or everything that exists. The nature of the world has been conceptualized differently in different fields. Some conceptions see the world as unique while others talk of a "plurality of worlds". Some treat the world as one simple object while others analyze the world as a complex made up of parts.
In scientific cosmology, the world or universe is commonly defined as "[t]he totality of all space and time; all that is, has been, and will be". Theories of modality talk of possible worlds as complete and consistent ways how things could have been. Phenomenology, starting from the horizon of co-given objects present in the periphery of every experience, defines the world as the biggest horizon or the "horizon of all horizons". In philosophy of mind, the world is contrasted with the mind as that which is represented by the mind. Theology conceptualizes the world in relation to God, for example, as God's creation, as identical to God or as the two being interdependent. In religions, there is a tendency to downgrade the material or sensory world in favor of a spiritual world to be sought through religious practice. A comprehensive representation of the world and our place in it, as is found in religions, is known as a worldview. Cosmogony is the field that studies the origin or creation of the world while eschatology refers to the science or doctrine of the last things or of the end of the world.
In various contexts, the term "world" takes a more restricted meaning associated, for example, with the Earth and all life on it, with humanity as a whole or with an international or intercontinental scope. In this sense, world history refers to the history of humanity as a whole and world politics is the discipline of political science studying issues that transcend nations and continents. Other examples include terms such as "world religion", "world language", "world government", "world war", "world population", "world economy", or "world championship". (Full article...)

Image 1Globalism has multiple meanings. In political science, it is used to describe "attempts to understand all of the interconnections of the modern world—and to highlight patterns that underlie (and explain) them". While primarily associated with world-systems, it can be used to describe other global trends. The concept of globalism is also classically used to focus on ideologies of globalization (the subjective meanings) instead of its processes (the objective practices); in this sense, "globalism" is to globalization what "nationalism" is to nationality.
The term is now frequently used as a pejorative by right wing movements and conspiracy theorists, as in the New World Order; it is sometimes associated with antisemitism, as antisemites frequently appropriate the term globalist to refer to certain Jews. (Full article...) -
Image 2Around the World in 80 Days with Michael Palin is a 7-part BBC television travel series first broadcast on BBC1 in 1989. It was presented by comedian and actor Michael Palin. The show was inspired by Jules Verne's classic 1873 novel Around the World in Eighty Days, in which a character named Phileas Fogg accepts a wager to circumnavigate the globe in eighty days or less.
Palin was given the same deadline, and not allowed to use aircraft, which did not exist in Jules Verne's time and would make completing the journey far too easy. He followed Phileas Fogg's route as closely as possible. Along the way he commented on the sights and cultures he encountered. Palin encountered several setbacks during his voyage, partly because he travelled with a five-person film crew, who are collectively named after Passepartout, Phileas Fogg's manservant.

Pangaea or Pangea (/pænˈdʒiː.ə/) was a supercontinent that existed during the late Paleozoic and early Mesozoic eras. It assembled from the earlier continental units of Gondwana, Euramerica and Siberia during the Carboniferous approximately 335 million years ago, and began to break apart about 200 million years ago, at the end of the Triassic and beginning of the Jurassic. In contrast to the present Earth and its distribution of continental mass, Pangaea was C-shaped, with the bulk of its mass stretching between Earth's northern and southern polar regions and surrounded by the superocean Panthalassa and the Paleo-Tethys and subsequent Tethys Oceans. Pangaea is the most recent supercontinent to have existed and the first to be reconstructed by geologists. (Full article...) -

In world history, post-classical history refers to the period from about 500 CE to 1500 CE, roughly corresponding to the European Middle Ages. The period is characterized by the expansion of civilizations geographically and the development of trade networks between civilizations. This period is also called the medieval era, post-antiquity era, post-ancient era, pre-modernity era, or pre-modern era.
In Asia, the spread of Islam created a series of caliphates and inaugurated the Islamic Golden Age, leading to advances in science in the medieval Islamic world and trade among the Asian, African, and European continents. East Asia experienced the full establishment of the power of Imperial China, which established several prosperous dynasties influencing Japan, Korea, and Vietnam. Religions such as Buddhism and neo-Confucianism spread in the region. Gunpowder was developed in China during the post-classical era. The Mongol Empire connected Europe and Asia, creating safe trade and stability between the two regions. In total, the population of the world doubled in the time period, from approximately 210 million in 500 CE to 461 million in 1500 CE. The population generally grew steadily throughout the period but endured some incidental declines due to events including the Plague of Justinian, the Mongol invasions, and the Black Death.

The Blue Marble is a photograph of Earth taken on December 7, 1972, from a distance of around 29,400 kilometers (18,300 miles) from the planet's surface.
The original image (NASA designation AS17-148-22727) was taken by either Ron Evans or Harrison Schmitt of the crew of the Apollo 17 spacecraft on its way to the Moon, and showed the Earth with the south pole facing upwards; since then, a cropped and rotated version has become one of the most reproduced images in history.

Image 7"We Are the World" is a charity single originally recorded by the supergroup USA for Africa in 1985. It was written by Michael Jackson and Lionel Richie and produced by Quincy Jones and Michael Omartian for the album We Are the World. With sales in excess of 20 million copies, it is the eighth-best-selling physical single of all time.
Soon after the British group Band Aid released "Do They Know It's Christmas?" in December 1984, the musician and activist Harry Belafonte decided to create an American benefit single for African famine relief. With the fundraiser Ken Kragen, he enlisted several musicians. Jackson and Richie completed the writing the night before the first recording session, on January 21, 1985. The event brought together some of the era's best-known musicians. (Full article...)

Spain, or the Kingdom of Spain, is a country located in Southwestern Europe, with parts of its territory in the Atlantic Ocean, the Mediterranean Sea and Africa. It is the largest country in Southern Europe and the fourth-most populous European Union member state. Spanning across the majority of the Iberian Peninsula, its territory also includes the Canary Islands in the Atlantic Ocean, the Balearic Islands in the Mediterranean Sea, and the autonomous cities of Ceuta and Melilla in Africa. Peninsular Spain is bordered to the north by France, Andorra, and the Bay of Biscay; to the east and south by the Mediterranean Sea and Gibraltar; and to the west by Portugal and the Atlantic Ocean. Spain's capital and largest city is Madrid, and other major urban areas include Barcelona, Valencia, Zaragoza, Seville, Málaga, Murcia, Palma de Mallorca, Las Palmas de Gran Canaria, and Bilbao.
In early antiquity, the Iberian Peninsula was inhabited by Celtic and Iberian tribes, along with other local pre-Roman peoples. With the Roman conquest of the Iberian Peninsula, the province of Hispania was established. Following the Romanization and Christianization of Hispania, the fall of the Western Roman Empire ushered in the inward migration of tribes from Central Europe, including the Visigoths, who formed the Visigothic Kingdom centred on Toledo. In the early eighth century, most of the peninsula was conquered by the Umayyad Caliphate, and during early Islamic rule, Al-Andalus became a dominant peninsular power centred in Córdoba. Several Christian kingdoms emerged in Northern Iberia, chief among them Asturias, León, Castile, Aragon, Navarre, and Portugal; made an intermittent southward military expansion and repopulation, known as the Reconquista, repelling Islamic rule in Iberia, which culminated with the Christian seizure of the Nasrid Kingdom of Granada in 1492. The dynastic union of the Crown of Castile and the Crown of Aragon in 1479 under the Catholic Monarchs is often considered the de facto unification of Spain as a nation-state. (Full article...)The Seven Wonders of the Ancient World, also known as the Seven Wonders of the World or simply the Seven Wonders, is a list of seven notable structures present during classical antiquity. The first known list of seven wonders dates back to the 2nd–1st century BC.
While the entries have varied over the centuries, the seven traditional wonders are the Great Pyramid of Giza, the Colossus of Rhodes, the Lighthouse of Alexandria, the Mausoleum at Halicarnassus, the Temple of Artemis, the Statue of Zeus at Olympia, and the Hanging Gardens of Babylon. Using modern-day countries, two of the wonders were located in Greece, two in Turkey, two in Egypt, and one in Iraq. Of the seven wonders, only the Pyramid of Giza, which is also by far the oldest of the wonders, still remains standing, while the others have been destroyed over the centuries. There is scholarly debate over the exact nature of the Hanging Gardens, and there is doubt as to whether they existed at all. (Full article...)Related portals

Image 3The protected areas of Nepal cover mainly forested land and are located at various altitudes in the Terai, in the foothills of the Himalayas and in the mountains, thus encompassing a multitude of landscapes and preserving a vast biodiversity in the Palearctic and Indomalayan realms.
Nepal covers 147,181 km2 (56,827 sq mi) in the central part of the Himalayas. Altitudes range from 67 m (220 ft) in the south-eastern Terai to 8,848 m (29,029 ft) at Mount Everest within a short horizontal span. This extreme altitudinal gradient has resulted in 11 bio-climatic zones ranging from lower tropical below 500 m (1,600 ft) to nival above 5,000 m (16,000 ft) in the High Himalayas, encompassing nine terrestrial ecoregions with 36 vegetation types.
Additionally, nine Ramsar sites were declared between 1988 and 2008. Two wildlife reserves were declared as national parks in 2017. (Full article...) -
Image 4Protected areas of Tasmania consist of protected areas located within Tasmania and its immediate onshore waters, including Macquarie Island. It includes areas of crown land (withheld land) managed by Tasmanian Government agencies as well as private reserves. As of 2016, 52% of Tasmania's land area has some form of reservation classification, the majority is managed by the Tasmania Parks & Wildlife Service (about 42% of total Tasmanian land area). Marine protected areas cover about 7.9% of state waters.
Within each classification of reserve there may be a variation of IUCN categories Australia is a signatory to the Convention of Biological Diversity and as such has obligations to report the status of its National Reserve System.IUCN provides on its website a prescription for activities consistent with the categorisation system. Changes made to the Nature Conservation Act 2002 in 2014 permit timber harvesting. These changes made in addition to the already established right to access minerals means that many of the IUCN categorisations assigned to individual reserves in Tasmania are no longer fit for purpose. In addition many reserves have had their reserve status downgraded from a class excluding timber harvesting and mineral extraction to ones where these activities are now permitted. This mis-application of the IUCN protected area categories needs to be remedied or the reserves protected land class under the Nature Conservation Act 2002 should be adjusted to reflect its currently assigned IUCN category.

Svalbard is an Arctic wilderness archipelago comprising the northernmost part of Norway. There are twenty-nine protected natural areas, consisting of seven national parks, six nature reserves, fifteen bird sanctuaries and one geotope protected area. In addition, human traces dating from before 1946 are automatically protected. The protected areas make up 39,800 square kilometers (15,400 sq mi) or 65% of the land area, and 78,000 square kilometers (30,000 sq mi) or 86.5% of the territorial waters. The largest protected areas are Nordaust-Svalbard Nature Reserve and Søraust-Svalbard Nature Reserve, which cover most of the areas east of the main island of Spitsbergen, including the islands of Nordaustlandet, Edgeøya, Barentsøya, Kong Karls Land and Kvitøya. Six of the national parks are located on Spitsbergen. Ten of the bird sanctuaries and the Moffen Nature Reserve are located within national parks. Five of the bird sanctuaries are Ramsar sites and fourteen of the bird sanctuaries are islands. Svalbard is on Norway's tentative list for nomination as a UNESCO World Heritage Site.
The supreme responsibility for conservation lies with the Norwegian Ministry of the Environment, which has delegated the management to the Governor of Svalbard and the Norwegian Directorate for Nature Management. The foundation for conservation was established in the Svalbard Treaty of 1920, and has been further specified in the Svalbard Environmental Act of 2001. The first round of protection took force on 1 July 1973, when most of the current protected areas came into effect. This included the two large nature reserves and three of the national parks. Moffen Nature Reserve was established in 1983, followed by four national parks, three nature reserves and one geotope protection area between 2002 and 2005. (Full article...) -
