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 age of Earth is estimated to be 4.54 ± 0.05 billion years (4.54 × 109 years ± 1%). This age may represent the age of Earth's accretion, or core formation, or of the material from which Earth formed. This dating is based on evidence from radiometric age-dating of meteorite material and is consistent with the radiometric ages of the oldest-known terrestrial material and lunar samples.
Following the development of radiometric age-dating in the early 20th century, measurements of lead in uranium-rich minerals showed that some were in excess of a billion years old. The oldest such minerals analyzed to date—small crystals of zircon from the Jack Hills of Western Australia—are at least 4.404 billion years old. Calcium–aluminium-rich inclusions—the oldest known solid constituents within meteorites that are formed within the Solar System—are 4.567 billion years old, giving a lower limit for the age of the Solar System.

Image 3The Global Climate Observing System (GCOS) was established in 1992 as an outcome of the Second World Climate Conference, to ensure that the observations and information needed to address climate-related issues are obtained and made available to all potential users. The GCOS is co-sponsored by the World Meteorological Organization (WMO), the Intergovernmental Oceanographic Commission (IOC) of UNESCO, the United Nations Environment Programme (UNEP), and the International Council for Science (ICSU). In order to assess and monitor the adequacy of in-situ observation networks as well as satellite-based observing systems, GCOS regularly reports on the adequacy of the current climate observing system to the United Nations Framework Convention on Climate Change (UNFCCC), and thereby identifies the needs of the current climate observing system.
GCOS is a system that comprises the climate-relevant components of many contributing observing systems and networks. Its mission is to help ensure that these contributing systems, taken as a whole, provide the comprehensive information on the global climate system that is required by users, including individuals, national and international organizations, institutions and agencies. The programme promotes the sustained provision and availability of reliable physical, chemical and biological observations and data records for the total climate system - across the atmospheric, oceanic and terrestrial domains, including the hydrological cycle, the carbon cycle and the cryosphere.

The Ocean Race is a yacht race around the world, held every three or four years since 1973. Originally named the Whitbread Round the World Race after its initiating sponsor, British brewing company Whitbread, in 2001 it became the Volvo Ocean Race after Swedish automobile manufacturer Volvo took up the sponsorship, and in 2019 it was renamed The Ocean Race
Each of the entries has a sailing crew who race day and night for more than 20 days at a time on some of the legs. Since the 2008–2009 race there has also been a dedicated media crew member called the On Board Reporter (OBR), who does not contribute to the sailing of the boat, but is responsible for sending images and video to race headquarters via satellite from the middle of the ocean. In the 2017–2018 race, the number of crew ranged between 7 and 10 (plus the OBR) depending on the gender ratio, with the rules providing an incentive to having women sailors on board.

Image 5Globalism has multiple meanings. In political science, it is used to describe "attempts to understand all the interconnections of the modern world—and to highlight patterns that underlie (and explain) them". While primarily associated with world-systems, it can be used to describe other global trends. The concept of globalism is also classically used to focus on the ideologies of globalization (the subjective meanings) instead of its processes (the objective practices); in this sense, "globalism" is to globalization what "nationalism" is to nationality.
The term is now frequently used as a pejorative by far-right movements and conspiracy theorists, as in the New World Order conspiracy theory; it is associated with antisemitism, as antisemites frequently appropriate the term globalist to refer to Jews. (Full article...) -
Image 6The "World Scientists' Warning to Humanity" was a document written in 1992 by Henry W. Kendall and signed by about 1,700 leading scientists. Twenty-five years later, in November 2017, 15,364 scientists signed "World Scientists' Warning to Humanity: A Second Notice" written by William J. Ripple and seven co-authors calling for, among other things, human population planning, and drastically diminishing per capita consumption of fossil fuels, meat, and other resources. The second notice has more scientist cosigners and formal supporters than any other journal article ever published. (Full article...)

The War of the Worlds is a science fiction novel by English author H. G. Wells. It was written between 1895 and 1897, and serialised in Pearson's Magazine in the UK and Cosmopolitan magazine in the US in 1897. The full novel was first published in hardcover in 1898 by William Heinemann. The War of the Worlds is one of the earliest stories to detail a conflict between humankind and an extraterrestrial race. The novel is the first-person narrative of an unnamed protagonist in Surrey and his younger brother in London as southern England is invaded by Martians. It is one of the most commented-on works in the science fiction canon.
The plot is similar to other works of invasion literature from the same period, and has been variously interpreted as a commentary on the theory of evolution, imperialism, and Victorian era fears, superstitions and prejudices. Wells later noted that inspiration for the plot was the catastrophic effect of European colonisation on the Aboriginal Tasmanians. Some historians have argued that Wells wrote the book to encourage his readership to question the morality of imperialism. At the time of publication, it was classified as a scientific romance, like Wells's earlier novel, The Time Machine. (Full article...)

Bangkok, officially known in Thai as Krung Thep Maha Nakhon and colloquially as Krung Thep, is the capital and most populous city of Thailand. The city occupies 1,568.7 square kilometres (605.7 sq mi) in the Chao Phraya River delta in central Thailand and has an estimated population of 9.0 million as of 2021, 13% of the country's population. Over 17.4 million people (25%) lived within the surrounding Bangkok Metropolitan Region at the 2021 estimate, making Bangkok an extreme primate city, dwarfing Thailand's other urban centres in both size and importance to the national economy.
Bangkok traces its roots to a small trading post during the Ayutthaya Kingdom in the 15th century, which eventually grew and became the site of two capital cities, Thonburi in 1767 and Rattanakosin in 1782. Bangkok was at the heart of the modernization of Siam, later renamed Thailand, during the late-19th century, as the country faced pressures from the West. The city was at the centre of Thailand's political struggles throughout the 20th century, as the country abolished absolute monarchy, adopted constitutional rule, and underwent numerous coups and several uprisings. The city, incorporated as a special administrative area under the Bangkok Metropolitan Administration in 1972, grew rapidly during the 1960s through the 1980s and now exerts a significant impact on Thailand's politics, economy, education, media and modern society.

Egypt (Arabic: مصر Miṣr [mesˁr], Egyptian Arabic pronunciation: [mɑsˤr]), officially the Arab Republic of Egypt, is a transcontinental country spanning the northeast corner of Africa and the Sinai Peninsula in the southwest corner of Asia. It is bordered by the Mediterranean Sea to the north, the Gaza Strip of Palestine and Israel to the northeast, the Red Sea to the east, Sudan to the south, and Libya to the west. The Gulf of Aqaba in the northeast separates Egypt from Jordan and Saudi Arabia. Cairo is the capital and largest city of Egypt, while Alexandria, the second-largest city, is an important industrial and tourist hub at the Mediterranean coast. At approximately 100 million inhabitants, Egypt is the 14th-most populated country in the world, and the third-most populated in Africa.
Egypt has one of the longest histories of any country, tracing its heritage along the Nile Delta back to the 6th–4th millennia BCE. Considered a cradle of civilisation, Ancient Egypt saw some of the earliest developments of writing, agriculture, urbanisation, organised religion and central government. Egypt was an early and important centre of Christianity, but largely adopted Islam in the seventh century. Cairo became the capital of the Fatimid Caliphate in the tenth century, and of the Mamluk Sultanate in the 13th century. Egypt then became part of the Ottoman Empire in 1517, before its local ruler Muhammad Ali established it as an autonomous Khedivate in 1867. The country was then occupied by the British Empire and gained independence in 1922 as a monarchy. Following the 1952 revolution, Egypt declared itself a republic, and in 1958 it merged with Syria to form the United Arab Republic, which was dissolved in 1961. Egypt fought several armed conflicts with Israel in 1948, 1956, 1967 and 1973, and occupyed the Gaza Strip intermittently until 1967. In 1978, Egypt signed the Camp David Accords, which recognised Israel in exchange for its withdrawal from the Sinai. After the Arab Spring, which led to the 2011 Egyptian revolution and overthrow of Hosni Mubarak, the country faced a protracted period of political unrest; this included the election in 2012 of a brief, short-lived Muslim Brotherhood-aligned Islamist government spearheaded by Mohamed Morsi, and its subsequent overthrow after mass protests in 2013.

The national parks of Madagascar include all officially recognized protected areas as of 2015. The protected areas network of Madagascar is managed by the Madagascar National Parks Association (PNM-ANGAP). The network includes three types of protected areas: Strict Nature Reserves (IUCN category Ia), National Parks (IUCN category II) and Wildlife Reserves (IUCN category IV). At the 2003 IUCN World Parks Congress in Durban, the Malagasy President, Marc Ravalomanana, announced an initiative to more than triple the area under protection from approximately 17,000 km2 (6,600 sq mi) to over 60,000 km2 (23,000 sq mi) (from 3% to 10% of Madagascar's area). This "Durban Vision", as it has been dubbed, involved broadening the definition of protected areas in the country and legislation has been passed to allow the creation of four new categories of protected area: Natural Parks (IUCN category II), Natural Monuments (IUCN category III), Protected Landscapes (IUCN category V), and Natural Resource Reserves (IUCN category VI). As well as allowing these new objectives for protected areas management, the new legislation also provided for entities other than PNM-ANGAP to manage protected areas, such as government ministries, community associations, NGOs and other civil society organizations, and the private sector.

Many parts of Scotland are protected in accordance with a number of national and international designations because of their environmental, historical or cultural value. Protected areas can be divided according to the type of resource which each seeks to protect. NatureScot has various roles in the delivery of many environmental designations in Scotland, i.e. those aimed at protecting flora and fauna, scenic qualities and geological features. Historic Environment Scotland is responsible for designations that protect sites of historic and cultural importance. Some international designations, such as World Heritage Sites, can cover both categories of site.
The various designations overlap considerably with many protected areas being covered by multiple designations with different boundaries. (Full article...) -
Image 14Protected 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...) -

It ranks 14th among all the states and union territories of India in terms of total protected area.
Protected areas in South India were created from private hunting grounds of the erstwhile Maharajas of the princely states. Mudumalai National Park was established in 1940 and was the first modern wildlife sanctuary in South India. The protected areas are administered by the Ministry of Environment and Forests of Government of India and the Tamil Nadu Forest Department. (Full article...)
