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...)

The World Wide Web ("WWW", "W3" or simply "the Web") is a global information medium that users can access via computers connected to the Internet. The term is often mistakenly used as a synonym for the Internet, but the Web is a service that operates over the Internet, just as email and Usenet do. The history of the Internet and the history of hypertext date back significantly further than that of the World Wide Web.
Tim Berners-Lee invented the World Wide Web while working at CERN in 1989. He proposed a "universal linked information system" using several concepts and technologies, the most fundamental of which was the connections that existed between information. He developed the first web server, the first web browser, and a document formatting protocol, called Hypertext Markup Language (HTML). After publishing the markup language in 1991, and releasing the browser source code for public use in 1993, many other web browsers were soon developed, with Marc Andreessen's Mosaic (later Netscape Navigator), being particularly easy to use and install, and often credited with sparking the Internet boom of the 1990s. It was a graphical browser which ran on several popular office and home computers, bringing multimedia content to non-technical users by including images and text on the same page.

A global city, also known as a power city, world city, alpha city, or world center, is a city that serves as a primary node in the global economic network. The concept originates from geography and urban studies, based on the thesis that globalization has created a hierarchy of strategic geographic locations with varying degrees of influence over finance, trade, and culture worldwide. The global city represents the most complex and significant hub within the international system, characterized by links binding it to other cities that have direct, tangible effects on global socioeconomic affairs.
The criteria of a global city have varied over time. Depending on the source, common features include a high degree of urban development, a large population, the presence of major multinational companies, a significant and globalized financial sector, a well-developed and internationally linked transportation infrastructure, local or national economic dominance, high quality educational and research institutions, and a globally influential output of ideas, innovations, or cultural products. Quintessential examples, based on most indices and research, include New York City, London, Paris, and Tokyo. (Full article...) -
Image 3The term "new world order" refers to a new period of history evidencing dramatic change in world political thought and the balance of power in international relations. Despite varied interpretations of this term, it is commonly associated with the notion of world governance.
The phrase "new world order" or similar language was used in the period toward the end of the First World War in relation to Woodrow Wilson's vision for international peace; Wilson called for a League of Nations to prevent aggression and conflict. In some instances when Franklin D. Roosevelt used the phrase "new world order", or "new order in the world" it was to refer to Axis powers plans for world domination. Although Roosevelt and Harry S. Truman may have been hesitant to use the phrase, commentators have applied the term retroactively to the order put in place by the World War II victors including the United Nations and the Bretton Woods system as a "new world order."

A cradle of civilization is a location and a culture where civilization was developed independent of other civilizations in other locations. The formation of urban settlements (cities) is the primary characteristic of a society that can be characterized as "civilized". Other characteristics of civilization include a sedentary non-nomadic population, monumental architecture, the existence of social classes and inequality, and the creation of a writing system for communication. The transition from simpler societies to the complex society of a civilization is gradual.
Scholars generally acknowledge six cradles of civilization: Mesopotamia, Ancient Egypt, Ancient India, and Ancient China are believed to be the earliest in Afro-Eurasia (previously called the Old World), while the Caral-Supe civilization of coastal Peru and the Olmec civilization of Mexico are believed to be the earliest in Americas - previously known in Western literature as the New World. 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, priests, and public works of the urban centers of the early civilizations.

The World Summit on the Information Society (WSIS) was a two-phase United Nations-sponsored summit on information, communication and, in broad terms, the information society that took place in 2003 in Geneva and in 2005 in Tunis. WSIS Forums have taken place periodically since then. One of the Summit's chief aims is to bridge the global digital divide separating rich countries from poor countries by increasing internet accessibility in the developing world. The conferences established 17 May as World Information Society Day.
The WSIS+10 Process marked the ten-year milestone since the 2005 Summit. In 2015, the stocktaking process culminated with a High-Level meeting of the UN General Assembly on 15 and 16 December in New York. (Full article...) -

The Space Age is a period encompassing the activities related to the space race, space exploration, space technology, and the cultural developments influenced by these events, beginning with the launch of Sputnik 1 on October 4, 1957, and continuing to the present.
This period is characterized by changes in emphasis on particular areas of space exploration and applications. Initially, the United States and the Soviet Union invested unprecedented amounts of resources in breaking records and being first to meet milestones in crewed and uncrewed exploration. The United States established the National Aeronautics and Space Administration (NASA) and the USSR established the Kosmicheskaya programma SSSR to meet these goals. This period of competition gave way to cooperation between those nations and emphasis on scientific research and commercial applications of space-based technology. (Full article...)

Buenos Aires (/ˌbweɪnəs ˈɛəriːz/ or /-ˈaɪrɪs/; Spanish pronunciation: [ˈbwenos ˈajɾes] ⓘ), officially the Autonomous City of Buenos Aires, is the capital and primate city of Argentina. The city is located on the western shore of the Río de la Plata, on South America's southeastern coast. "Buenos aires" is Spanish for "fair winds" or "good airs". Buenos Aires is classified as an Alpha global city, according to the Globalization and World Cities Research Network (GaWC) 2020 ranking.
The city of Buenos Aires is neither part of Buenos Aires Province nor the Province's capital; rather, it is an autonomous district. In 1880, after decades of political infighting, Buenos Aires was federalized and removed from Buenos Aires Province. The city limits were enlarged to include the towns of Belgrano and Flores; both are now neighborhoods of the city. The 1994 constitutional amendment granted the city autonomy, hence its formal name of Autonomous City of Buenos Aires. Its citizens first elected a Chief of Government in 1996; previously, the Mayor was directly appointed by the President of Argentina. (Full article...)Did you know - load new batch

Image 6Protected areas of Canada consist of approximately 12.1 percent of the nation's landmass and freshwater are considered conservation areas, including 11.4 percent designated as protected areas. Approximately 13.8 percent of Canada's territorial waters are conserved, including 8.9 percent designated as protected areas. Terrestrial areas conserved have increased by 65 percent in the 21st century, while marine areas conserved have increased by more than 3,800 percent.
Conservation and protected areas have different mandates depending on the organization which manages them, with some areas having a greater focus on ecological integrity, historical preservation, public usage, scientific research, or a combination of usages. Some areas such as the Polar Bear Pass, are co-managed and overseen by government and local indigenous agencies. (Full article...) -
Image 7Protected areas of Tasmania consist of protected areas located within Tasmania and its immediate onshore waters, including Macquarie Island. It includes areas of crown land (withheld land) managed by Tasmanian Government agencies as well as private reserves. As of 2016, 52% of Tasmania's land area has some form of reservation classification, the majority is managed by the Tasmania Parks & Wildlife Service (about 42% of total Tasmanian land area). Marine protected areas cover about 7.9% of state waters.
Within each classification of reserve there may be a variation of IUCN categories Australia is a signatory to the Convention of Biological Diversity and as such has obligations to report the status of its National Reserve System.IUCN provides on its website a prescription for activities consistent with the categorisation system. Changes made to the Nature Conservation Act 2002 in 2014 permit timber harvesting. These changes made in addition to the already established right to access minerals means that many of the IUCN categorisations assigned to individual reserves in Tasmania are no longer fit for purpose. In addition many reserves have had their reserve status downgraded from a class excluding timber harvesting and mineral extraction to ones where these activities are now permitted. This mis-application of the IUCN protected area categories needs to be remedied or the reserves protected land class under the Nature Conservation Act 2002 should be adjusted to reflect its currently assigned IUCN category.
