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...)

Image 1The cosmic egg, world egg or mundane egg is a mythological motif found in the cosmogonies of many cultures and civilizations, including in Proto-Indo-European mythology. Typically, there is an egg which, upon "hatching", either gives rise to the universe itself or gives rise to a primordial being who, in turn, creates the universe. The egg is sometimes lain on the primordial waters of the Earth. Typically, the upper half of the egg, or its outer shell, becomes the heaven (firmament) and the lower half, or the inner yolk, becomes the Earth. The motif likely stems from simple elements of an egg, including its ability to offer nourishment and give rise to new life, as is reflected by the Latin proverb omne vivum ex ovo ('all life comes from an egg').
The term "cosmic egg" is also used in the modern study of cosmology in the context of emergent Universe scenarios. (Full article...) -

The International Union for Conservation of Nature (IUCN) Red List of Threatened Species, also known as the IUCN Red List or Red Data Book, founded in 1964, is an inventory of the global conservation status and extinction risk of biological species. A series of Regional Red Lists, which assess the risk of extinction to species within a political management unit, are also produced by countries and organizations.
The goals of the Red List are to provide scientifically based information on the status of species and subspecies at a global level, to draw attention to the magnitude and importance of threatened biodiversity, to influence national and international policy and decision-making, and to provide information to guide actions to conserve biological diversity.

Image 3Economic globalization is one of the three main dimensions of globalization commonly found in academic literature, with the two others being political globalization and cultural globalization, as well as the general term of globalization.
Economic globalization refers to the widespread international movement of goods, capital, services, technology and information. It is the increasing economic integration and interdependence of national, regional, and local economies across the world through an intensification of cross-border movement of goods, services, technologies and capital. Economic globalization primarily comprises the globalization of production, finance, markets, technology, organizational regimes, institutions, corporations, and people.
While economic globalization has been expanding since the emergence of trans-national trade, it has grown at an increased rate due to improvements in the efficiency of long-distance transportation, advances in telecommunication, the importance of information rather than physical capital in the modern economy, and by developments in science and technology. The rate of globalization has also increased under the framework of the General Agreement on Tariffs and Trade and the World Trade Organization, in which countries gradually cut down trade barriers and opened up their current accounts and capital accounts. This recent boom has been largely supported by developed economies integrating with developing countries through foreign direct investment, lowering costs of doing business, the reduction of trade barriers, and in many cases cross-border migration.

Image 4The history of the Internet has its origin in the efforts of scientists and engineers to build and interconnect computer networks. The Internet Protocol Suite, the set of rules used to communicate between networks and devices on the Internet, arose from research and development in the United States and involved international collaboration, particularly with researchers in the United Kingdom and France.
Computer science was an emerging discipline in the late 1950s that began to consider time-sharing between computer users, and later, the possibility of achieving this over wide area networks. J. C. R. Licklider developed the idea of a universal network at the Information Processing Techniques Office (IPTO) of the United States Department of Defense (DoD) Advanced Research Projects Agency (ARPA). Independently, Paul Baran at the RAND Corporation proposed a distributed network based on data in message blocks in the early 1960s, and Donald Davies conceived of packet switching in 1965 at the National Physical Laboratory (NPL), proposing a national commercial data network in the United Kingdom.

The United Nations Climate Change Conferences are yearly conferences held in the framework of the United Nations Framework Convention on Climate Change (UNFCCC). They serve as the formal meeting of the UNFCCC parties – the Conference of the Parties (COP) – to assess progress in dealing with climate change, and beginning in the mid-1990s, to negotiate the Kyoto Protocol to establish legally binding obligations for developed countries to reduce their greenhouse gas emissions. Starting in 2005 the conferences have also served as the "Conference of the Parties Serving as the Meeting of Parties to the Kyoto Protocol" (CMP); also parties to the convention that are not parties to the protocol can participate in protocol-related meetings as observers. From 2011 to 2015 the meetings were used to negotiate the Paris Agreement as part of the Durban platform, which created a general path towards climate action. Any final text of a COP must be agreed by consensus.
The first UN Climate Change Conference was held in 1995 in Berlin. (Full article...) -

King of the Universe (Sumerian: lugal ki-sár-ra or lugal kiš-ki, Akkadian: šarru kiššat māti, šar-kiššati or šar kiššatim), also interpreted as King of Everything, King of the Totality, King of All or King of the World, was a title of great prestige claiming domination of the universe used by powerful monarchs in ancient Mesopotamia. The title is sometimes applied to God in the Abrahamic tradition.
The etymology of the title derives from the ancient Sumerian city of Kish (Sumerian: kiš, Akkadian: kiššatu), the original meaning being King of Kish. Although the equation of šar kiššatim as literally meaning "King of the Universe" was made during the Akkadian period, the title of "King of Kish" is older and was already seen as particularly prestigious, as the city of Kish was seen as having primacy over all other Mesopotamian cities. In Sumerian legend, Kish was the location where the kingship was lowered to from heaven after the legendary Flood. (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...)

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 and northeastern India. Kolkata is the seventh most populous city of India with an estimated city proper population of 4.5 million (0.45 crore). It is the centre of the Kolkata Metropolitan Region, one of the most populous metropolitan areas in the world with a population of over 15 million (1.5 crore) residents. Kolkata is the regarded by many sources as the cultural capital of India and a historically and culturally significant city in the historic region of Bengal. It is the second largest Bengali-speaking city in the world. It has the highest number of Nobel laureates among all cities in India.
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 licence 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...)Did you know - load new batch

Ukraine is a country in Eastern Europe. It is the second-largest European country after Russia, which borders it to the east and northeast. It also borders Belarus to the north; Poland, Slovakia, and Hungary to the west; and Romania and Moldova to the southwest; with a coastline along the Black Sea and the Sea of Azov to the south and southeast. Kyiv is the nation's capital and largest city, followed by Kharkiv, Dnipro and Odesa. Ukraine's official language is Ukrainian; Russian is also widely spoken, especially in the east and south.
During the Middle Ages, Ukraine was the site of early Slavic expansion and the area later became a key centre of East Slavic culture under the state of Kievan Rus', which emerged in the 9th century. The state eventually disintegrated into rival regional powers and was ultimately destroyed by the Mongol invasions of the 13th century. The area was then contested, divided, and ruled by a variety of external powers for the next 600 years, including the Polish–Lithuanian Commonwealth, the Austrian Empire, the Ottoman Empire, and the Tsardom of Russia. The Cossack Hetmanate emerged in central Ukraine in the 17th century marked on maps as "Ukraine, land of the Cossacks", but was partitioned between Russia and Poland, and ultimately absorbed by the Russian Empire. Ukrainian nationalism developed and, following the Russian Revolution in 1917, the short-lived Ukrainian People's Republic was formed. The Bolsheviks consolidated control over much of the former empire and established the Ukrainian Soviet Socialist Republic, which became a constituent republic of the Soviet Union when it was formed in 1922. In the early 1930s, millions of Ukrainians died in the Holodomor, a human-made famine. The German occupation during World War II in Ukraine was devastating, with 7 million Ukrainian civilians killed, including most Ukrainian Jews. (Full article...)Related portals

Image 2The main protected areas of Croatia are national parks, nature parks and strict reserves. There are 444 protected areas of Croatia, encompassing 9% of the country. Those include 8 national parks in Croatia, 2 strict reserves and 11 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 994 km2 (384 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 of nature conservation and spatial development. The State Institute for Nature Protection provides centralized oversight and expertise. (Full article...) -

Protected areas cover around 5% of the territory of Serbia. The Law on the Protection of the Nature defines these categories of protected areas:- Strict nature reserve — Area of unmodified natural features with representative ecosystems set aside for the preservation of its biodiversity and for scientific research and monitoring.
- Special nature reserve — Area of unmodified or slightly modified natural features of great importance due to uniqueness and rarity which includes the habitats of endangered species set aside for the preservation of its unique features, education, limited tourism and for scientific research and monitoring.
- National park — Area with large number of diverse ecosystems of national value, with outstanding natural features and/or cultural heritage set aside for the preservation of its natural resources and for educational, scientific and tourist use.
- Natural monument — Small unmodified or slightly modified natural feature, object or phenomenon, easily detectable and unique, with unique natural attributes.
- Protected habitat — Area which includes habitats of one or more wildlife species.
- Landscape of outstanding features — Area of remarkable appearance with important natural and cultural value.
- Nature park — Area of well-preserved natural values with preserved natural ecosystems and picturesque landscape set aside for the preservation of biodiversity and for educational, tourist, recreational and scientific use.

Image 9This is a list of the nationally designated protected areas of China. 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".
Take note that many protected areas in China have multiple official designations, and the statutory boundaries of these multi-designated PAs may be identical or may vary one from the other. 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 10Protected 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...) -
