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 anti-globalization movement, or counter-globalization movement, is a social movement critical of economic globalization. The movement is also commonly referred to as the global justice movement, alter-globalization movement, anti-globalist movement, anti-corporate globalization movement, or movement against neoliberal globalization. There are many definitions of anti-globalization.
Participants base their criticisms on a number of related ideas. What is shared is that participants oppose large, multinational corporations having unregulated political power, exercised through trade agreements and deregulated financial markets. Specifically, corporations are accused of seeking to maximize profit at the expense of work safety conditions and standards, labour hiring and compensation standards, environmental conservation principles, and the integrity of national legislative authority, independence and sovereignty. Some commentators have variously characterized changes in the global economy as "turbo-capitalism" (Edward Luttwak), "market fundamentalism" (George Soros), "casino capitalism" (Susan Strange), and as "McWorld" (Benjamin Barber).

The United Nations Conference on Trade and Development (UNCTAD) is an intergovernmental organization within the United Nations Secretariat that promotes the interests of developing countries in world trade. It was established in 1964 by the United Nations General Assembly (UNGA) and reports to that body and the United Nations Economic and Social Council (ECOSOC). UNCTAD is composed of 195 member states and works with nongovernmental organizations worldwide; its permanent secretariat is in Geneva, Switzerland.
The primary objective of UNCTAD is to formulate policies relating to all aspects of development, including trade, aid, transport, finance and technology. It was created in response to concerns among developing countries that existing international institutions like GATT (now replaced by the World Trade Organization), the International Monetary Fund (IMF), and the World Bank were not properly organized to handle the particular problems of developing countries; UNCTAD would provide a forum where developing nations could discuss and address problems relating to their economic development.

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.

The Human Development Index (HDI) is a statistical composite index of life expectancy, education (mean years of schooling completed and expected years of schooling upon entering the education system), and per capita income indicators, which is used to rank countries into four tiers of human development. A country scores a higher level of HDI when the lifespan is higher, the education level is higher, and the gross national income GNI (PPP) per capita is higher. It was developed by Pakistani economist Mahbub ul-Haq and was further used to measure a country's development by the United Nations Development Programme (UNDP)'s Human Development Report Office.
The 2010 Human Development Report introduced an Inequality-adjusted Human Development Index (IHDI). While the simple HDI remains useful, it stated that "the IHDI is the actual level of human development (accounting for inequality), while the HDI can be viewed as an index of 'potential' human development (or the maximum level of HDI) that could be achieved if there was no inequality."

A world map is a map of most or all of the surface of Earth. World maps, because of their scale, must deal with the problem of projection. Maps rendered in two dimensions by necessity distort the display of the three-dimensional surface of the Earth. While this is true of any map, these distortions reach extremes in a world map. Many techniques have been developed to present world maps that address diverse technical and aesthetic goals.
Charting a world map requires global knowledge of the Earth, its oceans, and its continents. From prehistory through the Middle Ages, creating an accurate world map would have been impossible because less than half of Earth's coastlines and only a small fraction of its continental interiors were known to any culture. With exploration that began during the European Renaissance, knowledge of the Earth's surface accumulated rapidly, such that most of the world's coastlines had been mapped, at least roughly, by the mid-1700s and the continental interiors by the twentieth century.

A sea is a large body of salty water. There are particular seas and the sea. The sea commonly refers to the ocean, the wider body of seawater.
Particular seas are either marginal seas, second-order sections of the oceanic sea (e.g. the Mediterranean Sea), or certain large, nearly landlocked bodies of water.
The salinity of water bodies varies widely, being lower near the surface and the mouths of large rivers and higher in the depths of the ocean; however, the relative proportions of dissolved salts vary little across the oceans. The most abundant solid dissolved in seawater is sodium chloride. The water also contains salts of magnesium, calcium, potassium, and mercury, amongst many other elements, some in minute concentrations. (Full article...) -

The New World Order (NWO) is a term used in several conspiracy theories which hypothesize a secretly emerging totalitarian world government. The common theme in conspiracy theories about a New World Order is that a secretive power elite with a globalist agenda is conspiring to eventually achieve world domination and rule the world through an authoritarian one-world government—which will replace sovereign nation-states—and an all-encompassing propaganda whose ideology hails the establishment of the New World Order as the culmination of history's progress. Many influential historical and contemporary figures have therefore been alleged to be part of a cabal that operates through many front organizations to orchestrate significant political and financial events, ranging from causing systemic crises to pushing through controversial policies, at both national and international levels, as steps in an ongoing plot to achieve world domination.
Before the early 1990s, New World Order conspiracism was limited to two American countercultures, primarily the militantly anti-government right, and secondarily the part of fundamentalist Christianity concerned with the eschatological end-time emergence of the Antichrist. Academics who study conspiracy theories and religious extremism, such as Michael Barkun and Chip Berlet, observed that right-wing populist conspiracy theories about a New World Order not only had been embraced by many seekers of stigmatized knowledge but also had seeped into popular culture, thereby fueling a surge of interest and participation in survivalism and paramilitarism as many people actively prepare for apocalyptic and millenarian scenarios. These political scientists warn that mass hysteria over New World Order conspiracy theories could eventually have devastating effects on American political life, ranging from escalating lone-wolf terrorism to the rise to power of authoritarian ultranationalist demagogues.

Shenzhen is a city and special economic zone on the east bank of the Pearl River estuary on the central coast of the southern Chinese province of Guangdong, bordering Hong Kong to the south, Dongguan to the north, and Huizhou to the northeast. With a population of 17.56 million in 2020, Shenzhen is the third most populous city by urban population in China after Shanghai and Beijing. Shenzhen is a global center in technology, research, manufacturing, business and economics, finance, tourism and transportation, and the Port of Shenzhen is the world's fourth busiest container port.
Shenzhen roughly follows the administrative boundaries of Bao'an County, which was established in imperial times. The southern portion of Bao'an County became part of British Hong Kong after the Opium Wars, while the village of Shenzhen was on the border. Shenzhen railway station was the last stop on the mainland Chinese section of the Kowloon–Canton Railway, and Shenzhen's economy grew and it became a city by 1979.

Brazil, officially the Federative Republic of Brazil, is the largest and easternmost country in South America and in Latin America. Brazil is the world's fifth-largest country by area and the seventh most populous. Its capital is Brasília, and its most populous city is São Paulo. The federation is composed of the union of the 26 states and the Federal District. It is the only country in the Americas to have Portuguese as an official language. Brazil is one of the most multicultural and ethnically diverse nations, due to over a century of mass immigration from around the world.
Bounded by the Atlantic Ocean on the east, Brazil has a coastline of 7,491 kilometers (4,655 mi). It borders all other countries and territories in South America except Ecuador and Chile and covers roughly half of the continent's land area. Its Amazon basin includes a vast tropical forest, home to diverse wildlife, a variety of ecological systems, and extensive natural resources spanning numerous protected habitats. This unique environmental heritage positions Brazil at number one of 17 megadiverse countries, and is the subject of significant global interest, as environmental degradation through processes like deforestation has direct impacts on global issues like climate change and biodiversity loss.

The popularity poll via free Web-based voting and small amounts of telephone voting was led by Canadian-Swiss Bernard Weber and organized by the New 7 Wonders Foundation (N7W) based in Zurich, Switzerland, with winners announced on 7 July 2007 in Lisbon, at Estádio da Luz. The poll was considered unscientific partly because it was possible for people to cast multiple votes. According to John Zogby, founder and current President/CEO of the Utica, New York–based polling organization Zogby International, New 7 Wonders Foundation drove "the largest poll on record".
The program drew a wide range of official reactions. Some countries touted their finalist and tried to get more votes cast for it, while others downplayed or criticized the contest. After supporting the New 7 Wonders Foundation at the beginning of the campaign by providing advice on nominee selection, the United Nations Educational, Scientific, and Cultural Organization (UNESCO), bound by its bylaws to record and give equal status to all World Heritage Sites, distanced itself from the undertaking in 2001 and again in 2007.
