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...)

A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map. Many techniques have been developed to present world maps that address diverse technical and aesthetic goals.
Charting a world map requires global knowledge of the Earth, its oceans, and its continents. From prehistory through the Middle Ages, creating an accurate world map would have been impossible because less than half of Earth's coastlines and only a small fraction of its continental interiors were known to any culture. With exploration that began during the European Renaissance, knowledge of the Earth's surface accumulated rapidly, such that most of the world's coastlines had been mapped, at least roughly, by the mid-1700s and the continental interiors by the twentieth century.

Since its creation in 1995, the World Trade Organization (WTO) has worked to maintain and develop international trade. As one of the largest international economic organizations (alongside the International Monetary Fund (IMF) and the World Bank), it has strong influence and control over trading rules and agreements, and thus has the ability to affect a country's economy immensely. The WTO policies aim to balance tariffs and other forms of economic protection with a trade liberalization policy, and to "ensure that trade flows as smoothly, predictably and freely as possible".
Indeed, the WTO claims that its actions "cut living costs and raise standards, stimulate economic growth and development, help countries develop, [and] give the weak a stronger voice." Statistically speaking, global trade has consistently grown between one and six percent per annum over the past decade, and US$38.8 billion were allocated to Aid for Trade in 2016.
Yet several criticisms of the WTO have arisen over time from a range of fields, including economists such as Dani Rodrik and Ha Joon Chang, and anthropologists such as Marc Edelman, who have argued that the institution "only serves the interests of multinational corporations, undermines local development, penalizes poor countries, [and] is increasing inequality", and have argued that some agreements about agriculture and pharmaceutical goods have led to restricted access to food and healthcare, thus causing large numbers of deaths. Several factors are alleged to contribute to these conditions, including but not limited to: the most favoured nation rule (MFN), national treatment policies, and failure to regard the infant industry argument. Critics argue that the policies that support these principles fail to protect developing nations, and in some cases take advantage of them. For example, UNCTAD estimates that market distortions cost developing countries $700 billion annually in lost export revenue. (Full article...) -

The League of Nations (LN or LoN; French: Société des Nations [sɔsjete de nɑsjɔ̃], SdN) was the first worldwide intergovernmental organisation whose principal mission was to maintain world peace. It was founded on 10 January 1920 by the Paris Peace Conference that ended the First World War. The main organization ceased operations on 18 April 1946 when many of its components were relocated into the new United Nations. As the template for modern global governance, the League profoundly shaped the modern world.
The League's primary goals were stated in its eponymous Covenant. They included preventing wars through collective security and disarmament and settling international disputes through negotiation and arbitration. Its other concerns included labour conditions, just treatment of native inhabitants, human and drug trafficking, the arms trade, global health, prisoners of war, and protection of minorities in Europe. The Covenant of the League of Nations was signed on 28 June 1919 as Part I of the Treaty of Versailles, and it became effective with the rest of the Treaty on 10 January 1920. Australia was granted the right to participate as an autonomous member nation, marking the start of Australian independence on the global stage. The first meeting of the Council of the League took place on 16 January 1920, and the first meeting of the Assembly of the League took place on 15 November 1920. In 1919, U.S. president Woodrow Wilson won the Nobel Peace Prize for his role as the leading architect of the League. (Full article...) -

Global health is the health of populations in a worldwide context; it has been defined as "the area of study, research, and practice that places a priority on improving health and achieving equity in health for all people worldwide". Problems that transcend national borders or have a global political and economic impact are often emphasized. Thus, global health is about worldwide health improvement (including mental health), reduction of disparities, and protection against global threats that disregard national borders, including the most common causes of human death and years of life lost from a global perspective.
Global health is not to be confused with international health, which is defined as the branch of public health focusing on developing nations and foreign aid efforts by industrialized countries. (Full article...) -
Image 5Ozone depletion and climate change are environmental challenges whose connections have been explored and which have been compared and contrasted, for example in terms of global regulation, in various studies and books.
There is widespread scientific interest in better regulation of climate change, ozone depletion and air pollution, as in general the human relationship with the biosphere is deemed of major historiographical and political significance. Already by 1994 the legal debates about respective regulation regimes on climate change, ozone depletion and air pollution were being dubbed "monumental" and a combined synopsis provided.

The World Chess Championship is played to determine the world champion in chess. The current world champion is Ding Liren, who defeated his opponent Ian Nepomniachtchi in the 2023 World Chess Championship. Magnus Carlsen, the previous world champion, had declined to defend his title.
The first event recognized as a world championship was the 1886 match between the two leading players in the world, Wilhelm Steinitz and Johannes Zukertort. Steinitz won, becoming the first world champion. From 1886 to 1946, the champion set the terms, requiring any challenger to raise a sizable stake and defeat the champion in a match in order to become the new world champion. Following the death of reigning world champion Alexander Alekhine in 1946, FIDE (the International Chess Federation) took over administration of the World Championship, beginning with the 1948 World Championship tournament. From 1948 to 1993, FIDE organized a set of tournaments to choose a new challenger every three years. In 1993, reigning champion Garry Kasparov broke away from FIDE, which led to a rival claimant to the title of World Champion for the next thirteen years. The titles were unified at the World Chess Championship 2006, and all subsequent matches have once again been administered by FIDE. (Full article...) -

A sea is a large body of salty water. There are particular seas and the sea. The sea commonly refers to the World Ocean, the wider body of seawater.
Particular seas are either marginal seas, second-order sections of the oceanic sea (e.g. the Mediterranean Sea), or certain large, nearly landlocked bodies of water.
The salinity of water bodies varies widely, being lower near the surface and the mouths of large rivers and higher in the depths of the ocean; however, the relative proportions of dissolved salts vary little across the oceans. The most abundant solid dissolved in seawater is sodium chloride. The water also contains salts of magnesium, calcium, potassium, and mercury, amongst many other elements, some in minute concentrations. A wide variety of organisms, including bacteria, protists, algae, plants, fungi, and animals live in the seas, which offers a wide range of marine habitats and ecosystems, ranging vertically from the sunlit surface and shoreline to the great depths and pressures of the cold, dark abyssal zone, and in latitude from the cold waters under polar ice caps to the warm waters of coral reefs in tropical regions. Many of the major groups of organisms evolved in the sea and life may have started there. (Full article...)

Shenzhen is a city and special economic zone on the east bank of the Pearl River estuary on the central coast of the southern Chinese province of Guangdong, bordering Hong Kong to the south, Dongguan to the north, Huizhou to the northeast, and Macau to the southwest. With a population of 17.5 million in 2020, Shenzhen is the third most populous city by urban population in China after Shanghai and Beijing. The Port of Shenzhen is the world's fourth busiest container port.
Shenzhen roughly follows the administrative boundaries of Bao'an County, which was established in imperial times. The southern portion of Bao'an County became part of British Hong Kong after the Opium Wars, while the village of Shenzhen was on the border. Shenzhen railway station was the last stop on the mainland Chinese section of the Kowloon–Canton Railway, and Shenzhen's economy grew and it became a city by 1979.

It borders Senegal to its north and Guinea to its southeast.
Guinea-Bissau was once part of the kingdom of Kaabu, as well as part of the Mali Empire. Parts of this kingdom persisted until the 18th century, while a few others had been under some rule by the Portuguese Empire since the 16th century. In the 19th century, it was colonised as Portuguese Guinea. Portuguese control was restricted and weak until the early 20th century, when its pacification campaigns solidified Portuguese sovereignty in the area. The final Portuguese victory over the last remaining bastion of mainland resistance came in 1915, with the conquest of the Papel-ruled Kingdom of Bissau by the Portuguese military officer Teixeira Pinto and the Wolof mercenary Abdul Injai.
