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 United Nations Framework Convention on Climate Change (UNFCCC) is the UN process for negotiating an agreement to limit dangerous climate change. It is an international treaty among countries to combat "dangerous human interference with the climate system". The main way to do this is limiting the increase in greenhouse gases in the atmosphere. It was signed in 1992 by 154 states at the United Nations Conference on Environment and Development (UNCED), informally known as the Earth Summit, held in Rio de Janeiro. The treaty entered into force on 21 March 1994. "UNFCCC" is also the name of the Secretariat charged with supporting the operation of the convention, with offices on the UN Campus in Bonn, Germany.
The convention's main objective is explained in Article 2. It is the "stabilization of greenhouse gas concentrations in the atmosphere at a level that would prevent dangerous anthropogenic [i.e., human-caused] interference with the climate system". The treaty calls for continuing scientific research into the climate. This research supports meetings and negotiations to lead to agreements. The aim is to allow ecosystems to adapt to climate change. At the same time it aims to ensure there are no threats to food production from climate change or measures to address it. And it aims to enable economic development to proceed in a sustainable manner. (Full article...) -

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...) -

The underworld, also known as the netherworld or hell, 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...) -

A world's fair, also known as a universal exhibition or an expo, is a large global exhibition designed to showcase the achievements of nations. These exhibitions vary in character and are held in different parts of the world at a specific site for a period of time, typically between three and six months.
The term "world's fair" is commonly used in the United States, while the French term, Exposition universelle ("universal exhibition") is used in most of Europe and Asia; other terms include World Expo or Specialised Expo, with the word expo used for various types of exhibitions since at least 1958.

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.

World-systems theory (also known as world-systems analysis or the world-systems perspective) is a multidisciplinary approach to world history and social change which emphasizes the world-system (and not nation states) as the primary (but not exclusive) unit of social analysis. World-systems theorists argue that their theory explains the rise and fall of states, income inequality, social unrest, and imperialism.
"World-system" refers to the inter-regional and transnational division of labor, which divides the world into core countries, semi-periphery countries, and periphery countries. Core countries have higher-skill, capital-intensive industries, and the rest of the world has low-skill, labor-intensive industries and extraction of raw materials. This constantly reinforces the dominance of the core countries. This structure is unified by the division of labour. It is a world-economy rooted in a capitalist economy. For a time, certain countries have become the world hegemon; during the last few centuries, as the world-system has extended geographically and intensified economically, this status has passed from the Netherlands, to the United Kingdom and (most recently) to the United States.

The Age of Discovery also known as the Age of Exploration, part of the early modern period and largely overlapping with the Age of Sail, was a period from approximately the late 15th century to the 17th century, during which seafarers from a number of European countries explored, colonized, and conquered regions across the globe. The Age of Discovery was a transformative period in world history when previously isolated parts of the world became connected to form the world system and laid the groundwork for globalization. The extensive overseas exploration, particularly the European colonization of the Americas, with the Spanish, Portuguese, and later the English, spurred in the International global trade. The interconnected global economy of the 21st century has its roots in the expansion of trade networks during this era.
The exploration also created colonial empires and marked an increased adoption of colonialism as a government policy in several European states. As such, it is sometimes synonymous with the first wave of European colonization. The colonization reshaped power dynamics causing geopolitical shifts in Europe and creating new centers of power beyond Europe. Having set human history on the global common course, the legacy of the Age still shapes the world today. (Full article...)

Iceland (Icelandic: Ísland, pronounced [ˈistlant] ⓘ) is a Nordic island country between the North Atlantic and Arctic Oceans, on the Mid-Atlantic Ridge between North America and Europe. It is linked culturally and politically with Europe and is the region's most sparsely populated country. Its capital and largest city is Reykjavík, which is home to about 36% of the country's roughly 380,000 residents. The official language of the country is Icelandic.
Located on a rift between tectonic plates, Iceland's geologic activity includes geysers and frequent volcanic eruptions. The interior consists of a volcanic plateau characterised by sand and lava fields, mountains, and glaciers, and many glacial rivers flow to the sea through the lowlands. Iceland is warmed by the Gulf Stream and has a temperate climate, despite a latitude just south of the Arctic Circle. Its high latitude and marine influence keep summers chilly, and most of its islands have a polar climate. (Full article...)Related portals

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.
