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...)

- Image 1Human 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.'

The ocean is the body of salt water that covers approximately 70.8% of Earth. The ocean is conventionally divided into large bodies of water, which are also referred to as oceans (the Pacific, Atlantic, Indian, Antarctic/Southern, and Arctic Ocean), and are themselves mostly divided into seas, gulfs and subsequent bodies of water. The ocean contains 97% of Earth's water and is the primary component of Earth's hydrosphere, acting as a huge reservoir of heat for Earth's energy budget, as well as for its carbon cycle and water cycle, forming the basis for climate and weather patterns worldwide. The ocean is essential to life on Earth, harbouring most of Earth's animals and protist life, originating photosynthesis and therefore Earth's atmospheric oxygen, still supplying half of it.
Ocean scientists split the ocean into vertical and horizontal zones based on physical and biological conditions. Horizontally the ocean covers the oceanic crust, which it shapes. Where the ocean meets dry land it covers relatively shallow continental shelfs, which are part of Earth's continental crust. Human activity is mostly coastal with high negative impacts on marine life. Vertically the pelagic zone is the open ocean's water column from the surface to the ocean floor. The water column is further divided into zones based on depth and the amount of light present. The photic zone starts at the surface and is defined to be "the depth at which light intensity is only 1% of the surface value" (approximately 200 m in the open ocean). This is the zone where photosynthesis can occur. In this process plants and microscopic algae (free-floating phytoplankton) use light, water, carbon dioxide, and nutrients to produce organic matter. As a result, the photic zone is the most biodiverse and the source of the food supply which sustains most of the ocean ecosystem. Light can only penetrate a few hundred more meters; the rest of the deeper ocean is cold and dark (these zones are called mesopelagic and aphotic zones). (Full article...) - Image 3
Gerardus Mercator 1512–1594
The Mercator world map of 1569 is titled Nova et Aucta Orbis Terrae Descriptio ad Usum Navigantium Emendate Accommodata (Renaissance Latin for "New and more complete representation of the terrestrial globe properly adapted for use in navigation"). The title shows that Gerardus Mercator aimed to present contemporary knowledge of the geography of the world and at the same time 'correct' the chart to be more useful to sailors. This 'correction', whereby constant bearing sailing courses on the sphere (rhumb lines) are mapped to straight lines on the plane map, characterizes the Mercator projection. While the map's geography has been superseded by modern knowledge, its projection proved to be one of the most significant advances in the history of cartography, inspiring the 19th century map historian Adolf Nordenskiöld to write "The master of Rupelmonde stands unsurpassed in the history of cartography since the time of Ptolemy." The projection heralded a new era in the evolution of navigation maps and charts and it is still their basis.The map is inscribed with a great deal of text. The framed map legends (or cartouches) cover a wide variety of topics: a dedication to his patron and a copyright statement; discussions of rhumb lines; great circles and distances; comments on some of the major rivers; accounts of fictitious geography of the north pole and the southern continent. The full Latin texts and English translations of all the legends are given below. Other minor texts are sprinkled about the map. They cover such topics as the magnetic poles, the prime meridian, navigational features, minor geographical details, the voyages of discovery and myths of giants and cannibals. These minor texts are also given below.

Around the World in Eighty Days (French: Le Tour du monde en quatre-vingts jours) is an adventure novel by the French writer Jules Verne, first published in French in 1872. In the story, Phileas Fogg of London and his newly employed French valet Passepartout attempt to circumnavigate the world in 80 days on a wager of £20,000 (equivalent to £2.3 million in 2023) set by his friends at the Reform Club. It is one of Verne's most acclaimed works. (Full article...) - Image 6
Juno in the Underworld by Jan Brueghel the Younger, between 1626 and 1630
The underworld, also known as the netherworld or hell, is the supernatural world of the dead in various religious traditions and myths, located below the world of the living. Chthonic is the technical adjective for things of the underworld.
The concept of an underworld is found in almost every civilization and "may be as old as humanity itself". Common features of underworld myths are accounts of living people making journeys to the underworld, often for some heroic purpose. Other myths reinforce traditions that the entrance of souls to the underworld requires a proper observation of ceremony, such as the ancient Greek story of the recently dead Patroclus haunting Achilles until his body could be properly buried for this purpose. People with high social status were dressed and equipped in order to better navigate the underworld.

Guangzhou, previously romanized as Canton or Kwangchow, is the capital and largest city of Guangdong province in southern China. Located on the Pearl River about 120 km (75 mi) northwest of Hong Kong and 145 km (90 mi) north of Macau, Guangzhou has a history of over 2,200 years and was a major terminus of the Silk Road.
The port of Guangzhou serves as a transportation hub for Guangzhou, one of China's three largest cities. Guangzhou was captured by the British during the First Opium War and no longer enjoyed a monopoly after the war; consequently it lost trade to other ports such as Hong Kong and Shanghai, but continued to serve as a major entrepôt. Following the Second Battle of Chuenpi in 1841, the Treaty of Nanking was signed between Sir Robert Peel on behalf of Queen Victoria and Lin Zexu on behalf of Emperor Xuanzong and ceded Hong Kong to the United Kingdom on 26 January 1841 after the agreement of the Convention of Chuenpi.

Liberia, officially the Republic of Liberia, is a country on the West African coast. It is bordered by Sierra Leone to its northwest, Guinea to its north, Ivory Coast to its east, and the Atlantic Ocean to its south and southwest. It has a population of around 5.5 million and covers an area of 43,000 square miles (111,369 km2). The official language is English. Over 20 indigenous languages are spoken, reflecting the country's ethnic and cultural diversity. The capital and largest city is Monrovia.
Liberia began in the early 19th century as a project of the American Colonization Society (ACS), which believed that black people would face better chances for freedom and prosperity in Africa than in the United States. Between 1822 and the outbreak of the American Civil War in 1861, more than 15,000 freed and free-born African Americans, along with 3,198 Afro-Caribbeans, relocated to Liberia. Gradually developing an Americo-Liberian identity, the settlers carried their culture and tradition with them while colonizing the indigenous population. Led by the Americo-Liberians, Liberia declared independence on July 26, 1847, which the U.S. did not recognize until February 5, 1862. (Full article...)

Network of protected areas in Albania (2020)
Despite being a relatively small country, Albania is exceedingly rich in biodiversity. Its ecosystems and habitats support over 5,550 species of vascular and non-vascular plants and more than 15,600 species of coniferous and non-coniferous evergreens, most of which are threatened at global and European levels. The country has made recent efforts to expand its network of protected areas which now include: 11 national parks, 1 marine park, 718 nature monuments, 23 managed nature reserves, 11 protected landscapes, 4 World Heritage Sites, 4 Ramsar sites and other protected areas of various categories, that when combined, account for 21.36% of the territory. Furthermore, a biosphere reserve, 45 important plant areas and 16 important bird areas are found in the country.
Meanwhile, the central government has proclaimed the Coastline and the Tirana Greenbelt as areas of national importance. (Full article...) - Image 5
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.
