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...)

King Kalākaua
The 1881 world tour of King Kalākaua of the Hawaiian Kingdom was his attempt to save the Hawaiian culture and population from extinction by importing a labor force from Asia-Pacific nations. His efforts brought the small island nation to the attention of world leaders, but sparked rumors that the kingdom was for sale. Critics in Hawaii believed the labor negotiations were just an excuse to see the world. The 281-day trip gave Kalākaua the distinction of being the first monarch to circumnavigate the globe; his 1874 travels had made him the first reigning monarch to visit the United States and the first honoree of a state dinner at the White House.

The World Series is the annual championship series of Major League Baseball (MLB), a professional baseball league operating in the United States and Canada, contested between the champion teams of the American League (AL) and the National League (NL). The winning team, determined through a best-of-seven playoff, is declared the champions of the league (often called "world champions") and awarded the Commissioner's Trophy. It was first played in 1903 to determine the championship team of baseball after the American League declared itself the second major-league circuit in the United States to compete with the previously established National League.
Qualification to the World Series is determined through a postseason tournament consisting of six teams per league — three teams who won their respective divisions and three teams who achieved the best win-loss record overall but failed to clinch a division title. The team which have won their league's tournament, or clinched a pennant, qualify for the World Series against the other league's pennant winner. (Full article...) -
Image 3Nao Victoria, the only ship in the fleet to complete the circumnavigation. Detail from a map by Abraham Ortelius, 1590.
The Magellan expedition, sometimes termed the Magellan–Elcano expedition, was a 16th-century Spanish expedition planned and initially led by Portuguese explorer Ferdinand Magellan and completed by the Spanish navigator Juan Sebastián Elcano which resulted in the first circumnavigation of the Earth. Its purpose was to secure a maritime trade route with the Moluccas, or Spice Islands, in present-day Indonesia. The expedition departed Spain in 1519 and returned there in 1522 under the command of Elcano, who continued the voyage after Magellan's death in the Philippines. One of the most significant voyages in the Age of Discovery, the nearly three-year expedition totaled 60,440 km (37,560 mi) and was the first to sail around the earth. It also marked the first crossing of the Pacific by a European expedition, revealing the vast scale of that ocean, and proved that ships could sail around the world on a western sea route.
The five-ship fleet left Spain on 20 September 1519 with about 270 men. After crossing the Atlantic Ocean, the ships continued south along the eastern coast of South America. Entering the Strait of Magellan on 1 November 1520, the fleet passed through to the Pacific Ocean, which Magellan himself named Mar Pacifico. The fleet crossed the Pacific in 98 days, stopped in Guam and the Philippines, and successfully reached the Moluccas in November 1521. A much-depleted crew led by Elcano finally returned to Spain on 6 September 1522, having sailed west across the Indian Ocean, around the Cape of Good Hope through waters controlled by the Portuguese, and north along the west African coast to finally arrive in Spain.

A prominent criticism against usage of the word in media is that it has become synonymous with the Western world, with the very noticeable exclusion of Asian (except Japan and Israel, owning to their influential alliances with the US), African and Latin American opinion.
The international community is a term used in geopolitics and international relations to refer to all recognized countries, or to a broad group of people and governments of the world. (Full article...) -
Image 5Planetary management is intentional global-scale management of Earth's biological, chemical and physical processes and cycles (water, carbon, nitrogen, sulfur, phosphorus, and others). Planetary management also includes managing humanity's influence on planetary-scale processes. Effective planetary management aims to prevent destabilisation of Earth's climate, protect biodiversity and maintain or improve human well-being. More specifically, it aims to benefit society and the global economy, and safeguard the ecosystem services upon which humanity depends – global climate, freshwater supply, food, energy, clean air, fertile soil, pollinators, and so on.
Because of the sheer complexity and enormous scope of the task, it remains to be seen whether planetary management is a feasible paradigm for maintaining global sustainability. The concept currently has defenders and critics on both sides: environmentalist David W. Orr questions whether such a task can be accomplished with human help and technology or without first examining the underlying human causes, while geographer Vaclav Smil acknowledges that "the idea of planetary management may seem preposterous to many, but at this time in history there is no rational alternative".

Image 6The global cuisine or world cuisine is a cuisine that is practiced around the world. A cuisine is a characteristic style of cooking that includes specific practices and traditions, often associated with a specific region, country, or culture. To become a global cuisine, a local, regional, or national cuisine must spread internationally and be commonly served around the world. There have been significant improvements and advances during the 20th century in food preservation, storage, shipping, and production, and today many countries, cities, and regions have access to their traditional cuisines and many other global cuisines.

Image 7The earliest human civilizations developed independently of each other and a cradle of civilization is a location and a culture from which one of them emerged. A civilization is any complex society characterized by the development of a 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.

Seoul, officially Seoul Special Metropolitan City, is the capital and largest city of South Korea, and the largest city in the whole of Korea. The broader Seoul Metropolitan Area, encompassing Seoul, Gyeonggi Province and Incheon, emerged as the world's sixth largest metropolitan economy in 2022, behind New York, Tokyo, Los Angeles, Paris, and London, and hosts more than half of South Korea's population. Although Seoul's population peaked at over 10 million, it has gradually decreased since 2014, standing at about 9.6 million residents as of 2024.
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 Empire of Japan, temporarily renamed "Keijō" ("Gyeongseong" in Korean). 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...)

Sri Lanka, officially the Democratic Socialist Republic of Sri Lanka, formerly known as Ceylon, is an island country in South Asia. It is located in the Indian Ocean, southwest of the Bay of Bengal, and is separated from India by the Gulf of Mannar and the Palk Strait. Sri Lanka shares a maritime border with the Maldives to the southwest and India to the northwest, and lies across the Bay of Bengal from Bangladesh and Myanmar to the northeast and the Andaman and Nicobar Islands of India to the east. Its executive and judicial capital is Colombo, which is also its largest city and the political, financial and cultural centre of the country; neighboring Sri Jayawardenepura Kotte is the legislative capital. Sri Lanka's population is 22 million. About 74% of the population are Sinhalese, who speak the Sinhala language, and about 15% are Tamils who speak the Tamil language. Other long-established ethnic groups include the Moors, Indian Tamils, Burghers, Malays, Chinese, and Vedda.
The island has a documented history of over 3,000 years, with evidence of prehistoric human settlement dating back 125,000 years. Sri Lanka has been given various names throughout its long history, with Ceylon most notably being used prior to its independence in 1948. The earliest known Buddhist writings in the island, known collectively as the Pali Canon, date back to 29 BCE. Sri Lanka, owing to its strategic geographical location, played a role as a major trading hub, and was well known to explorers across the world as early as the Anuradhapura period. The Portuguese Empire established a colony in the sixteenth century, during a period of political upheaval in the Kingdom of Kotte where it also faced attacks from neighbouring kingdoms of Kandy and Sitawaka. Following the Sinhalese–Portuguese War, the Dutch colonial empire controlled the coastal areas. By the early 19th century, the British Empire established a colony on the island, which lasted until 1948. The early 20th century saw the rise of nationalist movements and increasing calls for independence. In 1948, Sri Lanka gained independence as the Dominion of Ceylon, eventually becoming a republic in 1972. Sri Lanka's recent history has been marred by a prolonged civil war between the Tamil separatist militant organisation of Liberation Tigers of Tamil Eelam and the Sri Lankan Armed Forces, which lasted from 1983 to 2009, and ended with the defeat of the separatists.

Protected areas in Tanzania (Hifadhi za Mali hai za Tanzania, in Swahili) are extremely varied, ranging from sea habitats over grasslands to the top of the Kilimanjaro, the tallest mountain in Africa. About a third of the country's total area is protected to a certain degree as a national park, game reserve, marine park, forest reserve or the like. 840 protected areas are spread across 7,330 km2 of ocean and 361,594 km2 of land in Tanzania. The coastal and marine areas are less protected than terrestrial ecosystems, which are given the highest level of protection. Tanzania is one of the world's major biodiversity hotspots thanks to its vast national parks, "the Eastern Arc" mountains, wetlands, coastal forests, marine, and freshwater systems as remarkable reservoirs of plant and animal species. A wide range of endemic species of birds, reptiles, snakes, amphibians, wild coffee variations, and the well-known African violet flower can also be found in Tanzania. (Full article...) -

Elephant poaching, particularly in the south of the country in areas such as Zakouma National Park, is a severe problem. (Full article...) -
Image 5China has more than 10,000 protected areas, covering eighteen percent of the country's land. There are many forms of protected areas in China. Based on their relative importance, each type of protected area can be further graded into two to three levels (national, provincial and prefectural/county level). Nevertheless, the highest rank for "pocket nature preserve" (social and mass-based), "no-hunting area", "no-fishing area", "no-logging area", "wild medicinal material resources conservation area", "crop germplasm resources conservation area", "forest tree germplasm resources conservation area" or "source water protection area" is practically restricted to provincial level. The local government at county level is also responsible for the delimitation and declaration of "basic farmland protection area" and "basic grassland".
Many protected areas (PAs) in China have multiple official designations, and the statutory boundaries of these multi-designated PAs may be identical or may vary from one another. For instance, the boundaries of Huangshan NSHA coincide with those of the Huangshan NGP, whereas Fujian province's Wuyi Mountains NNR, NSHA and NFP are adjacent to each other. In Heilongjiang, 27,642.14 hectares out of 115,340.27 hectares of Huzhong NFP are intersected with the experiment zone of Huzhong NNR. (Full article...) -
Image 6Illinois has a variety of protected areas, including over 123 state-protected areas, dozens of federally protected areas, hundreds of county-level and municipal park areas, and historic sites under various governmental levels of protection. Illinois also contains sites designated as internationally important protected areas. These multiple levels of protection contribute to a statewide network of numerous recreation opportunities and conservation schemes, sometimes in a small area. For example, DeKalb County contains a 1,000-acre (4.0 km2) forest preserve system and a 1,500-acre (6.1 km2) state park (Shabbona Lake State Park); within DeKalb County, the DeKalb Park District in the City of DeKalb has a 700-acre (2.8 km2) park system.
