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...)

The Human Development Index (HDI) is a statistical composite index of life expectancy, education (mean years of schooling completed and expected years of schooling upon entering the education system), and per capita income indicators, which is used to rank countries into four tiers of human development. A country scores a higher level of HDI when the lifespan is higher, the education level is higher, and the gross national income GNI (PPP) per capita is higher. It was developed by Pakistani economist Mahbub ul-Haq and was further used to measure a country's development by the United Nations Development Programme (UNDP)'s Human Development Report Office.
The 2010 Human Development Report introduced an Inequality-adjusted Human Development Index (IHDI). While the simple HDI remains useful, it stated that "the IHDI is the actual level of human development (accounting for this inequality), while the HDI can be viewed as an index of "potential" human development (or the maximum level of HDI) that could be achieved if there was no inequality."

Gerardus Mercator (/dʒɪˈrɑːrdəs mɜːrˈkeɪtər/; 5 March 1512 – 2 December 1594) was a Flemish geographer, cosmographer and cartographer. He is most renowned for creating the 1569 world map based on a new projection which represented sailing courses of constant bearing (rhumb lines) as straight lines—an innovation that is still employed in nautical charts.
Mercator was a notable maker of globes and scientific instruments. In addition, he had interests in theology, philosophy, history, mathematics and geomagnetism. He was also an accomplished engraver and calligrapher. Unlike other great scholars of the age, he travelled little and his knowledge of geography came from his library of over a thousand books and maps, from his visitors and from his vast correspondence (in six languages) with other scholars, statesmen, travellers, merchants and seamen. Mercator's early maps were in large formats suitable for wall mounting but in the second half of his life, he produced over 100 new regional maps in a smaller format suitable for binding into his Atlas of 1595. This was the first appearance of the word Atlas in reference to a book of maps. However, Mercator used it as a neologism for a treatise (Cosmologia) on the creation, history and description of the universe, not simply a collection of maps. He chose the word as a commemoration of the Titan Atlas, "King of Mauretania", whom he considered to be the first great geographer. (Full article...) -

Symbols commonly associated with six of the religions labelled "world religions:” clockwise from the top, these represent Hinduism, Buddhism, Jainism, Sikhism, Judaism, and Christianity, and Islam.
World religions is a category used in the study of religion to demarcate at least five—and in some cases more—religions that are deemed to have been especially large, internationally widespread, or influential in the development of Western society. Buddhism, Christianity, Hinduism, Islam, and Judaism are always included in the list. From a perspective of theological objectivity and totality, inclusion of other religions in the category, such as that of Sikhism, and to lesser degree, Shinto is too observed.These are often juxtaposed against other categories, such as folk religions, Indigenous religions, and new religious movements (NRMs), which are also used by scholars in this field of research. Less dividing is the concept of major religious groups. (Full article...) -
Image 4Contemptus mundi, the "contempt of the world" and worldly concerns, is a theme in the intellectual life of both Classical Antiquity and of Christianity, both in its mystical vein and its ambivalence towards secular life, that figures largely in the Western world's history of ideas. In inculcating a turn of mind that would lead to a state of serenity untrammeled by distracting material appetites and feverish emotional connections, which the Greek philosophers called ataraxia, it drew upon the assumptions of Stoicism and a neoplatonism that was distrustful of deceptive and spurious appearances. In the familiar rhetorical polarity in Hellenic philosophy between the active and the contemplative life, which Christians, who expressly rejected "the World, the Flesh and the Devil", might exemplify as the way of Martha and the way of Mary, contemptus mundi assumed that only the contemplative life was of lasting value and the world an empty shell, a vanity.

Several cosmological and mythological systems portray four corners of the world or four quarters of the world corresponding approximately to the four points of the compass (or the two solstices and two equinoxes). At the center may lie a sacred mountain, garden, world tree, or other beginning-point of creation. Often four rivers run to the four corners of the world, and water or irrigate the four quadrants of Earth. (Full article...) -
Image 6The Snowball Earth is a geohistorical hypothesis that proposes during one or more of Earth's icehouse climates, the planet's surface became entirely or nearly entirely frozen with no liquid oceanic or surface water exposed to the atmosphere. The most academically referred period of such global glaciation is believed to have occurred sometime before 650 mya during the Cryogenian period.
Proponents of the hypothesis argue that it best explains sedimentary deposits that are generally believed to be of glacial origin at tropical palaeolatitudes and other enigmatic features in the geological record. Opponents of the hypothesis contest the geological evidence for global glaciation and the geophysical feasibility of an ice- or slush-covered ocean, and they emphasize the difficulty of escaping an all-frozen condition. Several unanswered questions remain, including whether Earth was a full snowball or a "slushball" with a thin equatorial band of open (or seasonally open) water. The snowball-Earth episodes are proposed to have occurred before the sudden radiation of multicellular bioforms known as the Cambrian explosion. The most recent snowball episode may have triggered the evolution of multicellularity. (Full article...) -
Image 7Human security is a paradigm for understanding global vulnerabilities whose proponents challenge the traditional notion of national security through military security by arguing that the proper referent for security should be at the human rather than the national level. Human security reveals a people-centred and multi-disciplinary understanding of security which involves a number of research fields, including development studies, international relations, strategic studies, and human rights. The United Nations Development Programme's 1994 Human Development Report is considered a milestone publication in the field of human security, with its argument that ensuring "freedom from want" and "freedom from fear" for all persons is the best path to tackle the problem of global insecurity.
Critics of the concept argue that its vagueness undermines its effectiveness, that it has become little more than a vehicle for activists wishing to promote certain causes, and that it does not help the research community understand what security means or help decision-makers to formulate good policies. Alternatively, other scholars have argued that the concept of human security should be broadened to encompass military security: 'In other words, if this thing called 'human security' has the concept of 'the human' embedded at the heart of it, then let us address the question of the human condition directly. Thus understood, human security would no longer be the vague amorphous add-on to harder-edged areas of security such as military security or state security.' (Full article...)

Seoul, officially Seoul Special City, is the capital of the Republic of Korea (ROK), commonly known as South Korea, and the country's most extensive urban center. The broader Seoul Capital Area, encompassing Gyeonggi province and Incheon metropolitan city, emerged as the world's fourth largest metropolitan economy in 2014, trailing only Tokyo, New York City, and Los Angeles, hosting more than half of South Korea's population. Although Seoul's population peaked at slightly over 10 million, it has gradually decreased since 2014, standing at approximately 9.97 million residents as of 2020. Seoul is the seat of the South Korean government.
Seoul's history traces back to 18 BC when it was founded by the people of Baekje, one of the Three Kingdoms of Korea. During the Joseon dynasty, Seoul was officially designated as the capital, surrounded by the Fortress Wall of Seoul. In the early 20th century, Seoul was occupied by the Japanese Empire, temporarily renamed "Gyeongseong." The Korean War brought fierce battles, with Seoul changing hands four times and leaving the city mostly in ruins. Nevertheless, the city has since undergone significant reconstruction and rapid urbanization. (Full article...)Did you know - load new batch

Belgium, officially the Kingdom of Belgium, is a country in Northwestern Europe. The country is bordered by the Netherlands to the north, Germany to the east, Luxembourg to the southeast, France to the south, and the North Sea to the west. It covers an area of 30,689 km2 (11,849 sq mi) and has a population of more than 11.5 million, making it the 22nd most densely populated country in the world and the 6th most densely populated country in Europe, with a density of 376/km2 (970/sq mi). Belgium is part of an area known as the Low Countries, historically a somewhat larger region than the Benelux group of states, as it also included parts of northern France. The capital and largest metropolitan region is Brussels; other major cities are Antwerp, Ghent, Charleroi, Liège, Bruges, Namur, and Leuven.
Belgium is a sovereign state and a federal constitutional monarchy with a parliamentary system. Its institutional organization is complex and is structured on both regional and linguistic grounds. It is divided into three highly autonomous regions: the Flemish Region (Flanders) in the north, the Walloon Region (Wallonia) in the south, and the Brussels-Capital Region. Brussels is the smallest and most densely populated region, as well as the richest region in terms of GDP per capita. Belgium is also home to two main linguistic communities: the Flemish Community, which constitutes about 60 percent of the population, and the French Community, which constitutes about 40 percent of the population. A small German-speaking Community, making up around one percent of the population, exists in the East Cantons. The Brussels-Capital Region is officially bilingual in French and Dutch, although French is the majority language and lingua franca. Belgium's linguistic diversity and related political conflicts are reflected in its complex system of governance, made up of six different governments.

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 1Protected areas of Canada consist of approximately 12.1 percent of the nation's landmass and freshwater are considered conservation areas, including 11.4 percent designated as protected areas. Approximately 13.8 percent of Canada's territorial waters are conserved, including 8.9 percent designated as protected areas. Terrestrial areas conserved have increased by 65 percent in the 21st century, while marine areas conserved have increased by more than 3,800 percent.
Conservation and protected areas have different mandates depending on the organization which manages them, with some areas having a greater focus on ecological integrity, historical preservation, public usage, scientific research, or a combination of usages. Some areas such as the Polar Bear Pass, are co-managed and overseen by government and local indigenous agencies. (Full article...) -

Protected areas of the United Kingdom are areas in the United Kingdom which need and /or receive protection because of their environmental, historical or cultural value to the nation. Methods and aims of protection vary depending on the nature and importance of the resource. Protection operates at local, regional, national and international levels, and may be backed by legislation and international treaty, or less formally by planning policy.
Within the United Kingdom, different approaches are taken to some forms of protection within the constituent countries of England, Scotland, Wales and Northern Ireland, while other forms of protection are more consistent across the UK. Protected areas can be divided according to the type of resource which each seeks to protect. Primarily, these are: scenic or landscape value; biodiversity value (species and habitats); geodiversity value (relating to geology and geomorphology); and cultural or historic value. Several types of protected areas are focused on more than one of these areas. (Full article...) -
Image 4According to the California Protected Areas Database (CPAD), in the state of California, United States, there are over 14,000 inventoried protected areas administered by public agencies and non-profits. In addition, there are private conservation areas and other easements. They include almost one-third of California's scenic coastline, including coastal wetlands, estuaries, beaches, and dune systems. The California State Parks system alone has 270 units and covers 1.3 million acres (5,300 km2), with over 280 miles (450 km) of coastline, 625 miles (1,006 km) of lake and river frontage, nearly 18,000 campsites, and 3,000 miles (5,000 km) of hiking, biking, and equestrian trails.
Obtaining an accurate total of all protected land in California and elsewhere is a complex task. Many parcels have inholdings, private lands within the protected areas, which may or may not be accounted for when calculating total area. Also, occasionally one parcel of land is included in two or more inventories. Over 90% of Yosemite National Park for example, is listed both as wilderness by the National Wilderness Preservation System, and as national park land by the National Park Service. The Cosumnes River Preserve is an extreme example, owned and managed by a handful of public agencies and private landowners, including the Bureau of Land Management, the County of Sacramento and The Nature Conservancy. Despite the difficulties, the CPAD gives the total area of protected land at 49,294,000 acres (199,490 km2), or 47.05% of the state (not including easements); a considerable amount for the most populous state in the country.
