The World Portal

A world is a totality of entities. In philosophy, the world is customarily viewed as all of existence or the whole of reality. Some conceptions see the world as unique, while others examine the character of entities that exist in the world or talk of a plurality of worlds, challenging the idea that the world is an all-inclusive whole. The term is also commonly used as a context-dependent expression to denote a specific domain of discourse and everything within it, such as the Earth and all life on it or the whole of human existence.

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 conceptualises 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 favour 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 biological and geological future of Earth can be extrapolated based on the estimated effects of several long-term influences. These include the chemistry at Earth's surface, the cooling rate of the planet's interior, gravitational interactions with other objects in the Solar System, and a steady increase in the Sun's luminosity. An uncertain factor is the influence of human technology such as climate engineering, which could cause significant changes to the planet. For example, the current Holocene extinction is being caused by technology, and the effects may last for up to five million years. In turn, technology may result in the extinction of humanity, leaving the planet to gradually return to a slower evolutionary pace resulting solely from long-term natural processes.

Over time intervals of hundreds of millions of years, random celestial events pose a global risk to the biosphere, which can result in mass extinctions. These include impacts by comets or asteroids and the possibility of a near-Earth supernova—a massive stellar explosion within a 100-light-year (31-parsec) radius of the Sun. Other large-scale geological events are more predictable. Milankovitch's theory predicts that the planet will continue to undergo glacial periods at least until the Quaternary glaciation comes to an end. These periods are caused by the variations in eccentricity, axial tilt, and precession of Earth's rotation and orbit. As part of the ongoing supercontinent cycle, plate tectonics will probably create a supercontinent in 250–350 million years. Sometime in the next 1.5–4.5 billion years, Earth's axial tilt may begin to undergo chaotic variations, with changes in the axial tilt of up to 90°. (Full article...)

Countries by total wealth, 2022 (2023 publication)

National net wealth, also known as national net worth, is the total sum of the value of a country's assets minus its liabilities. It is the total value of net wealth possessed by the residents of a state at a set point in time. Figures in this article only cover household wealth, and exclude government wealth, which may be substantial, as in China, or negative, as in the UK or US, and so do not show total wealth.

National net wealth is an important indicator of a nation's ability to take on debt and sustain spending and is influenced not only by real estate prices, equity market prices, exchange rates, liabilities and incidence in a country of the population, but also by human resources, natural resources, and capital and technological advancements, which may create new assets or render others worthless in the future.

World government is a theoretical single political authority with jurisdiction over all of Earth and humanity. A world government with executive, legislative, and judicial functions and an administrative apparatus has never existed.

The inception of the United Nations (UN) in the mid-20th century remains the closest approximation to a world government, as it is by far the largest and most powerful international institution. The UN is mostly limited to an advisory role, with the stated purpose of fostering cooperation between existing national governments, rather than exerting authority over them. (Full article...)

Laws concerning gender identity-expression by country or territory in 2025:
  Legal identity change, surgery not required, but not gender self-identification
  Legal identity change, surgery required
  No legal identity change

Rights affecting lesbian, gay, bisexual, transgender and queer (LGBTQ) people vary greatly by country or jurisdiction—encompassing everything from the legal recognition of same-sex marriage to the death penalty for homosexuality.
Notably, as of January 2025^[update], 38 countries recognize same-sex marriage. By contrast, not counting non-state actors and extrajudicial killings, only two countries are believed to impose the death penalty on consensual same-sex sexual acts: Iran and Afghanistan. The death penalty is officially law, but generally not practiced, in Mauritania, Saudi Arabia, and Somalia (in the autonomous state of Jubaland). LGBTQ people also face extrajudicial killings in the Russian region of Chechnya. Sudan rescinded its unenforced death penalty for anal sex (hetero- or homosexual) in 2020. Fifteen countries have stoning on the books as a penalty for adultery, which (in light of the illegality of gay marriage in those countries) would by default include gay sex, but this is enforced by the legal authorities in Iran and Nigeria (in the northern third of the country).

Kolkata, also known as Calcutta (its official name until 2001), is the capital and largest city of the Indian state of West Bengal. It lies on the eastern bank of the Hooghly River, 80 km (50 mi) west of the border with Bangladesh. It is the primary financial and commercial centre of eastern India and one of the gateways to northeastern India. Kolkata is the seventh most populous city in India with an estimated city proper population of 4.5 million while its metropolitan region Kolkata Metropolitan Area is the third most populous metropolitan region of India with a metro population of over 15 million. Kolkata is regarded by many sources as the cultural capital of India and a historically and culturally significant city in the historic region of Bengal.

The three villages that predated Calcutta were ruled by the Nawab of Bengal under Mughal suzerainty. After the Nawab granted the East India Company a trading license in 1690, the area was developed by the Company into Fort William. Nawab Siraj ud-Daulah occupied the fort in 1756 but was defeated at the Battle of Plassey in 1757, after his general Mir Jafar mutinied in support of the company, and was later made the Nawab for a brief time. Under company and later crown rule, Calcutta served as the de facto capital of India until 1911. Calcutta was the second largest city in the British Empire, after London, and was the centre of bureaucracy, politics, law, education, science and the arts in India. The city was associated with many of the figures and movements of the Bengali Renaissance. It was the hotbed of the Indian nationalist movement. (Full article...)

Libya, officially the State of Libya, is a country in the Maghreb region of North Africa. It borders the Mediterranean Sea to the north, Egypt to the east, Sudan to the southeast, Chad to the south, Niger to the southwest, Algeria to the west, and Tunisia to the northwest. With an area of almost 1.8 million km² (700,000 sq mi), Libya is the fourth-largest country in Africa and the Arab world, and the 16th-largest in the world. The country claims 32,000 square kilometres of southeastern Algeria, south of the Libyan town of Ghat. The capital and largest city is Tripoli, located in the northwest and containing over a million of Libya's seven million people.

Libya has been inhabited by Berbers since the late Bronze Age as descendants from Iberomaurusian and Capsian cultures. In classical antiquity, the Phoenicians established city-states and trading posts in western Libya, while several Greek cities were established in the East. Parts of Libya were variously ruled by Carthaginians, Numidians, Persians, and Greeks before the entire region became a part of the Roman Empire. Libya was an early centre of Christianity. After the fall of the Western Roman Empire, the area of Libya was mostly occupied by the Vandals until the 7th century when invasions brought Islam to the region. From then on, centuries of Arab migration to the Maghreb shifted the demographic scope of Libya in favour of Arabs. In the 16th century, the Spanish Empire and the Knights Hospitaller occupied Tripoli until Ottoman rule began in 1551. Libya was involved in the Barbary Wars of the 18th and 19th centuries. Ottoman rule continued until the Italo-Turkish War in 1911, which resulted in Italy occupying Libya and establishing two colonies: Italian Tripolitania and Italian Cyrenaica, later unified in the Italian Libya colony from 1934 to 1943.

There are about 10,000 protected areas, covering about a third of the country. The method and aims of protection vary according to the importance of the resource and whether it is publicly or privately owned.

Nearly 30 percent of New Zealand's land mass is publicly owned with some degree of protection. Most of this land – about 80,000 square kilometres (31,000 sq mi) – is administered by the Department of Conservation. There are 13 national parks, thousands of reserves, 54 conservation parks, and a range of other conservation areas. (Full article...)

The northernmost tip of Prins Karls Forland in Forlandet National Park

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...)

The main protected areas of Croatia are national parks, nature parks and strict reserves. There are 411 protected areas of Croatia, encompassing 9% of the country. Those include 8 national parks, 2 strict reserves and 13 nature parks. The most famous protected area and the oldest national park in Croatia is the Plitvice Lakes National Park, a UNESCO World Heritage Site. Velebit Nature Park is a part of the UNESCO Man and the Biosphere Programme. The strict and special reserves, as well as the national and nature parks, are managed and protected by the central government, while other protected areas are managed by counties. In 2005, the National Ecological Network was set up, as the first step in preparation of the EU accession and joining of the Natura 2000 network.

The total area of all national parks in the country is 930 km² (359 sq mi), of which 235 km² (91 sq mi) is sea surface. Each of the national parks is maintained by a separate institution, overseen and funded by the government ministry overseeing nature conservation. Ministry of Environmental Protection and Green Transition provides centralized oversight, expertise and management of the Register of Protected Natural Values of Croatia, the work done in the past by the State Institute for Nature Protection.
