The world

The Blue Marble, a photograph of the planet Earth made on 7 December 1972 by the crew of the Apollo 17 spacecraft.

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 largest Antarctic ozone hole recorded as of September 2006

  
  The Montreal Protocol is an international treaty designed to protect the ozone layer by phasing out the production of numerous substances that are responsible for ozone depletion. It was agreed on 16 September 1987, and entered into force on 1 January 1989. Since then, it has undergone nine revisions, in 1990 (London), 1991 (Nairobi), 1992 (Copenhagen), 1993 (Bangkok), 1995 (Vienna), 1997 (Montreal), 1998 (Australia), 1999 (Beijing) and 2016 (Kigali) As a result of the international agreement, the ozone hole in Antarctica is slowly recovering. Climate projections indicate that the ozone layer will return to 1980 levels between 2040 (across much of the world) and 2066 (over Antarctica). Due to its widespread adoption and implementation, it has been hailed as an example of successful international co-operation. Former UN Secretary-General Kofi Annan stated that "perhaps the single most successful international agreement to date has been the Montreal Protocol". In comparison, effective burden-sharing and solution proposals mitigating regional conflicts of interest have been among the success factors for the ozone depletion challenge, where global regulation based on the Kyoto Protocol has failed to do so. In this case of the ozone depletion challenge, there was global regulation already being installed before a scientific consensus was established. Also, overall public opinion was convinced of possible imminent risks.
  
  The ozone treaty has been ratified by 198 parties (197 states and the European Union), making them the first universally ratified treaties in United Nations history. (Full article...)

  The political history of the world is the history of the various political entities created by the human race throughout their existence and the way these states define their borders. Throughout history, political systems have expanded from basic systems of self-governance and monarchy to the complex democratic and totalitarian systems that exist today. In parallel, political entities have expanded from vaguely defined frontier-type boundaries, to the national definite boundaries existing today. (Full article...)

  Path of the Centurion under the command of George Anson

  
  While Great Britain was fighting the War of Jenkins' Ear with Spain in 1740, Commodore George Anson led a squadron of eight ships on a mission to disrupt or capture the Pacific Ocean possessions of the Spanish Empire. Returning to Britain in 1744 by way of China and thus completing a circumnavigation of the globe, the voyage was notable for the capture of the Manila galleon, but also for horrific losses from disease with only 188 men of the original 1,854 surviving. An account of the voyage was published in 1748 which being widely read by the general public was a great commercial success and "is still esteemed as the story of a remarkable voyage extremely well told."

  Evidence of possibly the oldest forms of life on Earth has been found in hydrothermal vent precipitates.

  
  The earliest known life forms on Earth may be as old as 4.1 billion years old (or Ga) according to biologically fractionated graphite inside a single zircon grain in the Jack Hills range of Australia. The earliest evidence of life found in a stratigraphic unit, not just a single mineral grain, is the 3.7 Ga metasedimentary rocks containing graphite from the Isua Supracrustal Belt in Greenland. The earliest direct known life on land may be stromatolites which have been found in 3.480-billion-year-old geyserite uncovered in the Dresser Formation of the Pilbara Craton of Western Australia. Various microfossils of microorganisms have been found in 3.4 Ga rocks, including 3.465-billion-year-old Apex chert rocks from the same Australian craton region, and in 3.42 Ga hydrothermal vent precipitates from Barberton, South Africa. Much later in the geologic record, likely starting in 1.73 Ga, preserved molecular compounds of biologic origin are indicative of aerobic life. Therefore, the earliest time for the origin of life on Earth is at least 3.5 billion years ago, possibly as early as 4.1 billion years ago — not long after the oceans formed 4.5 billion years ago and after the formation of the Earth 4.54 billion years ago.

  Changes in surface air temperature over the past 50 years. The Arctic has warmed the most, and temperatures on land have generally increased more than sea surface temperatures.

  
  In common usage, climate change describes global warming—the ongoing increase in global average temperature—and its effects on Earth's climate system. Climate change in a broader sense also includes previous long-term changes to Earth's climate. The current rise in global average temperature is more rapid than previous changes, and is primarily caused by humans burning fossil fuels. Fossil fuel use, deforestation, and some agricultural and industrial practices add to greenhouse gases, notably carbon dioxide and methane. Greenhouse gases absorb some of the heat that the Earth radiates after it warms from sunlight. Larger amounts of these gases trap more heat in Earth's lower atmosphere, causing global warming.
  
  Climate change has an increasingly large impact on the environment. Deserts are expanding, while heat waves and wildfires are becoming more common. Amplified warming in the Arctic has contributed to thawing permafrost, retreat of glaciers and sea ice decline. Higher temperatures are also causing more intense storms, droughts, and other weather extremes. Rapid environmental change in mountains, coral reefs, and the Arctic is forcing many species to relocate or become extinct. Even if efforts to minimise future warming are successful, some effects will continue for centuries. These include ocean heating, ocean acidification and sea level rise. (Full article...)

  A Roberts loom in a weaving shed in the United Kingdom in 1835

  
  The Industrial Revolution, sometimes divided into the First Industrial Revolution and Second Industrial Revolution, was a period of global transition of the human economy towards more widespread, efficient and stable manufacturing processes that succeeded the Agricultural Revolution. Beginning in Great Britain, the Industrial Revolution spread to continental Europe and the United States, during the period from around 1760 to about 1820–1840. This transition included going from hand production methods to machines; new chemical manufacturing and iron production processes; the increasing use of water power and steam power; the development of machine tools; and the rise of the mechanized factory system. Output greatly increased, and the result was an unprecedented rise in population and the rate of population growth. The textile industry was the first to use modern production methods, and textiles became the dominant industry in terms of employment, value of output, and capital invested.
  
  Many of the technological and architectural innovations were of British origin. By the mid-18th century, Britain was the world's leading commercial nation, controlling a global trading empire with colonies in North America and the Caribbean. Britain had major military and political hegemony on the Indian subcontinent; particularly with the proto-industrialised Mughal Bengal, through the activities of the East India Company. The development of trade and the rise of business were among the major causes of the Industrial Revolution. Developments in law also facilitated the revolution, such as courts ruling in favour of property rights. An entrepreneurial spirit and consumer revolution helped drive industrialisation in Britain, which after 1800, was emulated in Belgium, the United States, and France. (Full article...)

  Yggdrasil, a modern attempt to reconstruct the Norse world tree which connects the heavens, the earth and the underworld

  
  The underworld, also known as the netherworld, 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. (Full article...)

Skyline of Mexico City with the Torre Latinoamericana

Mexico City (Spanish: Ciudad de México, locally [sjuˈða(ð) ðe ˈmexiko] ^ⓘ; abbr.: CDMX; Central Nahuatl: Mexihco Hueyaltepetl, Nahuatl pronunciation: [meːˈʃiʔko wejaːlˈtepeːt͡ɬ]; Otomi: 'Monda) is the capital and largest city of Mexico, and the most populous city in North America. Mexico City is one of the most important cultural and financial centers in the world. It is located in the Valley of Mexico within the high Mexican central plateau, at an altitude of 2,240 meters (7,350 ft). The city has 16 boroughs or demarcaciones territoriales, which are in turn divided into neighborhoods or colonias.

The 2020 population for the city proper was 9,209,944, with a land area of 1,495 square kilometers (577 sq mi). According to the most recent definition agreed upon by the federal and state governments, the population of Greater Mexico City is 21,804,515, which makes it the sixth-largest metropolitan area in the world, the second-largest urban agglomeration in the Western Hemisphere (behind São Paulo, Brazil), and the largest Spanish-speaking city (city proper) in the world. Greater Mexico City has a GDP of $411 billion in 2011, which makes it one of the most productive urban areas in the world. The city was responsible for generating 15.8% of Mexico's GDP, and the metropolitan area accounted for about 22% of the country's GDP. If it were an independent country in 2013, Mexico City would be the fifth-largest economy in Latin America. (Full article...)

Bhutan (/buːˈtɑːn/ ^ⓘ boo-TAHN; Dzongkha: འབྲུག་ཡུལ་, romanized: Druk Yul [ʈuk̚˩.yː˩]), officially the Kingdom of Bhutan (Dzongkha: འབྲུག་རྒྱལ་ཁབ་, romanized: Druk Gyal Khap), is a landlocked country in South Asia situated in the Eastern Himalayas between China in the north and India in the south. With a population of over 727,145 and a territory of 38,394 square kilometres (14,824 sq mi), Bhutan ranks 133rd in land area and 160th in population. Bhutan is a constitutional monarchy with a king (Druk Gyalpo) as the head of state and a prime minister as the head of government. Vajrayana Buddhism is the state religion and the Je Khenpo is the head of the state religion.

The subalpine Himalayan mountains in the north rise from the country's lush subtropical plains in the south. In the Bhutanese Himalayas, there are peaks higher than 7,000 metres (23,000 ft) above sea level. Gangkhar Puensum is Bhutan's highest peak and is the highest unclimbed mountain in the world. The wildlife of Bhutan is notable for its diversity, including the Himalayan takin and golden langur. The capital and largest city is Thimphu, holding close to 15% of the population.

The Seven Wonders of the Ancient World (from left to right, top to bottom): Great Pyramid of Giza, Hanging Gardens of Babylon, Temple of Artemis, Statue of Zeus at Olympia, Mausoleum at Halicarnassus, Colossus of Rhodes, and the Lighthouse of Alexandria

The Seven Wonders of the Ancient World, also known as the Seven Wonders of the World or simply the Seven Wonders, is a list of seven notable structures present during classical antiquity. The first known list of seven wonders dates back to the 2nd–1st century BC.

While the entries have varied over the centuries, the seven traditional wonders are the Great Pyramid of Giza, the Colossus of Rhodes, the Lighthouse of Alexandria, the Mausoleum at Halicarnassus, the Temple of Artemis, the Statue of Zeus at Olympia, and the Hanging Gardens of Babylon. Using modern-day countries, two of the wonders were located in Greece, two in Turkey, two in Egypt, and one in Iraq. Of the seven wonders, only the Pyramid of Giza, which is also by far the oldest of the wonders, still remains standing, while the others have been destroyed over the centuries. There is scholarly debate over the exact nature of the Hanging Gardens, and there is doubt as to whether they existed at all. (Full article...)

  Protected 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.
