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 "the 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...)

A multinational corporation (MNC); also called a multinational enterprise (MNE), transnational enterprise (TNE), transnational corporation (TNC), international corporation, or stateless corporation, is a corporate organization that owns and controls the production of goods or services in at least one country other than its home country. Control is considered an important aspect of an MNC to distinguish it from international portfolio investment organizations, such as some international mutual funds that invest in corporations abroad solely to diversify financial risks.

Most of the current largest and most influential companies are publicly traded multinational corporations, including Forbes Global 2000 companies. (Full article...)

A globe is a spherical model of Earth, of some other celestial body, or of the celestial sphere. Globes serve purposes similar to maps, but, unlike maps, they do not distort the surface that they portray except to scale it down. A model globe of Earth is called a terrestrial globe. A model globe of the celestial sphere is called a celestial globe.

A globe shows details of its subject. A terrestrial globe shows landmasses and water bodies. It might show nations and major cities and the network of latitude and longitude lines. Some have raised relief to show mountains and other large landforms. A celestial globe shows notable stars, and may also show positions of other prominent astronomical objects. Typically, it will also divide the celestial sphere into constellations. (Full article...)

Indigenous peoples are non-dominant people groups descended from the original inhabitants of their territories, especially territories that have been colonized. The term lacks a precise authoritative definition, although in the 21st century designations of Indigenous peoples have focused on self-identification, cultural difference from other groups in a state, a special relationship with their traditional territory, and an experience of subjugation and discrimination under a dominant cultural model.

Estimates of the population of Indigenous peoples range from 250 million to 600 million. There are some 5,000 distinct Indigenous peoples spread across every inhabited climate zone and inhabited continent of the world. Most Indigenous peoples are in a minority in the state or traditional territory they inhabit and have experienced domination by other groups, especially non-Indigenous peoples. Although many Indigenous peoples have experienced colonization by settlers from European nations, Indigenous identity is not determined by Western colonization. (Full article...)

The first around the world sailing record for circumnavigation of the world can be attributed to the surviving crew of Ferdinand Magellan's expedition, including the last captain Juan Sebastián Elcano who completed their journey in 1522.

Although not in a single voyage, Magellan was technically the first to circumnavigate the globe since he was killed in the Mactan Islands and while in the Kingdom of Portugal's service, Magellan had already reached the Malay Archipelago in Southeast Asia on previous voyages traveling east (from 1505 to 1511–1512). By visiting this area again but now traveling west, Magellan achieved a nearly complete personal circumnavigation of the globe for the first time in history. (Full article...)

A cradle of civilization is a location and a culture where civilization was developed independently of other civilizations in other locations. A civilization is any complex society characterized by the development of the state, social stratification, urbanization, and symbolic systems of communication beyond signed or spoken languages (namely, writing systems and graphic arts).

Scholars generally acknowledge six cradles of civilization: Mesopotamia, Ancient Egypt, Ancient India and Ancient China are believed to be the earliest in Afro-Eurasia, while the Caral–Supe civilization of coastal Peru and the Olmec civilization of Mexico are believed to be the earliest in the Americas. All of the cradles of civilization depended upon agriculture for sustenance (except possibly Caral–Supe which may have depended initially on marine resources). All depended upon farmers producing an agricultural surplus to support the centralized government, political leaders, religious leaders, and public works of the urban centers of the early civilizations.

The Seal of the International Monetary Fund

The International Monetary Fund (IMF) is an international financial institution and a specialized agency of the United Nations, headquartered in Washington, D.C. It consists of 191 member countries, and its stated mission is "working to foster global monetary cooperation, secure financial stability, facilitate international trade, promote high employment and sustainable economic growth, and reduce poverty around the world." The IMF acts as a lender of last resort to its members experiencing actual or potential balance of payments crises.

Established in July 1944 at the Bretton Woods Conference based on the ideas of Harry Dexter White and John Maynard Keynes, the IMF came into formal existence in 1945 with 29 member countries and the goal of reconstructing the international monetary system. For its first three decades, the IMF oversaw the Bretton Woods system of fixed exchange rate arrangements. Following the collapse of this system in 1971, the Fund's role shifted to managing balance-of-payments difficulties and international financial crises, becoming a key institution in the era of globalization.

The Paris Agreement (also called the Paris Accords or Paris Climate Accords) is an international treaty on climate change that was signed in 2016. The treaty covers climate change mitigation, adaptation, and finance. The Paris Agreement was negotiated by 196 parties at the 2015 United Nations Climate Change Conference near Paris, France. As of February 2023, 195 members of the United Nations Framework Convention on Climate Change (UNFCCC) are parties to the agreement. Of the three UNFCCC member states which have not ratified the agreement, the only major emitter is Iran. The United States, the second largest emitter, withdrew from the agreement in 2020, rejoined in 2021, and announced its withdrawal again in 2025.

The Paris Agreement has a long-term temperature goal which is to keep the rise in global surface temperature to well below 2 °C (3.6 °F) above pre-industrial levels. The treaty also states that preferably the limit of the increase should only be 1.5 °C (2.7 °F). These limits are defined as averages of the global temperature as measured over many years.

Tianjin Eye on the Hai River

Tianjin is a major international port city in China. It is a direct-administered municipality on the shore of the Bohai Sea making it separate from the surrounding Hebei province. It is one of the nine national central cities, with a total population of 13,866,009 inhabitants at the time of the 2020 Chinese census. Its metropolitan area, which is made up of 12 central districts (other than Baodi, Jizhou, Jinghai and Ninghe), was home to 11,165,706 inhabitants in 2015 and is also the world's 29th-largest agglomeration (between Chengdu and Rio de Janeiro) and 11th-most populous city proper.

Tianjin is governed as one of the four municipalities (alongside Beijing, Shanghai, and Chongqing) under the direct administration of the State Council of China. However, it is the only municipality with a population of less than 20 million. The city borders Hebei Province and Beijing Municipality, bounded to the east by the Bohai Gulf portion of the Yellow Sea. Part of the Bohai Economic Rim, it is the largest coastal city in Northern China and part of the Jing-Jin-Ji megapolis. (Full article...)

Wonders of the World -

The Seven Wonders of Canada was a 2007 competition sponsored by CBC Television's The National and CBC Radio One's Sounds Like Canada. They sought to determine Canada's "seven wonders" by receiving nominations from viewers, and then from on-line voting of the short list. After the vote, a panel of judges, Ra McGuire, Roy MacGregor and Roberta L. Jamieson, picked the winners based on geographic and poetic criteria. Their seven picks were revealed on The National on June 7, 2007, making the official Seven Wonders of Canada, the Canoe, the Igloo, Niagara Falls, Old Quebec City, Pier 21 Halifax, Prairie Skies, and the Rockies. CBC anchor Peter Mansbridge commented on the top winner, “it’s hard to imagine Canada being Canada without the canoe. Explorers, missionaries, fur traders and First Nations—they’re all linked by this subtle and simple craft. To many, the quintessential Canadian experience begins by picking up a paddle. That’s why the canoe is one of the seven wonders” (Osler 2014). There were over 25,000 nominations and 1 million votes cast, according to the CBC website. The top audience votes were the Sleeping Giant, Niagara Falls, the Bay of Fundy, Nahanni National Park Reserve, the Northern Lights, the Rockies, and the Cabot Trail. The CBC website has a dedicated section for the Seven Wonders of Canada (https://www.cbc.ca/sevenwonders/index.html). (Full article...)

Many parts of Scotland are protected in accordance with a number of national and international designations because of their environmental, historical or cultural value. Protected areas can be divided according to the type of resource which each seeks to protect. NatureScot has various roles in the delivery of many environmental designations in Scotland, i.e. those aimed at protecting flora and fauna, scenic qualities and geological features. Historic Environment Scotland is responsible for designations that protect sites of historic and cultural importance. Some international designations, such as World Heritage Sites, can cover both categories of site.

The various designations overlap considerably with many protected areas being covered by multiple designations with different boundaries. (Full article...)

The 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...)
