World

The World is the planet Earth and all life on it, including human civilization. In a philosophical context, the "world" is the whole of the physical Universe, or an ontological world. In a theological context, the world is the material or the profane sphere, as opposed to the celestial, spiritual, transcendent or sacred spheres. "End of the world" scenarios refer to the end of human history, often in religious contexts. The history of the World is commonly understood as the history of humanity spanning the major geopolitical developments of about five millennia, from the first civilizations to the present. In terms such as world religion, world language, world government, and world war, the term world suggests an international or intercontinental scope without necessarily implying participation of every part of the world. The world population is the sum of all human populations at any time; similarly, the world economy is the sum of the economies of all societies or countries, especially in the context of globalization. Terms such as "world championship", "gross world product", and "world flags" imply the sum or combination of all sovereign states.

                                               

Demographics of the world

Demographics of the world include population density, ethnicity, education level, health measures, economic status, religious affiliations and other aspects of the human population of Earth. The worlds overall population density is 50 people per km² 129.28 per sq. mile, excluding Antarctica. Nearly two-thirds of the worlds population lives in Asia, with more than 2.5 billion in the countries of China and India combined. The worlds literacy rate has increased dramatically in the last 40 years, from 66.7% in 1979 to 86.3% today. This low rate is mostly attributable to poverty. Lower literacy rates are mostly found in South Asia, West Asia and Sub-Saharan Africa. The worlds largest ethnic group is Han Chinese, with Mandarin being the worlds most spoken language in terms of native speakers. The worlds population is predominantly urban and suburban, and there has been significant migration toward cities and urban centres. The urban population jumped from 29% in 1950 to 55.3% in 2018. Working backwards from the United Nations prediction that the world will be 51.3 percent urban by 2010, Dr. Ron Wimberley, Dr. Libby Morris and Dr. Gregory Fulkerson estimated 23 May 2007 would have been the first time the urban population outnumbered the rural population in history. China and India are the most populous countries, as the birth rate has consistently dropped in developed countries and until recently remained high in developing countries. Tokyo is the largest urban conglomeration in the world. The total fertility rate of the World is estimated at 2.43 2017, world bank children per woman, which is above the global average for the replacement fertility rate of approximately 2.33 as of 2003, meaning the worlds population is growing. However, world population growth is unevenly distributed, with the total fertility rate going from 0.83 in Singapore, to 6.49 in Niger. The United Nations estimated an annual population increase of 1.14% for the year of 2000. The current world population growth is approximately 1.09%. People under 18 years of age made up over a quarter of the world population 29.3%, and people age 65 and over made up less than one-tenth 7.9% in 2011. The world population more than tripled during the 20th century from about 1.65 billion in 1900 to 5.97 billion in 1999. It reached the 2 billion mark in 1927, the 3 billion mark in 1960, 4 billion in 1974, and 5 billion in 1987. The overall population of the world is approximately 7.7 billion as of December 2018. Currently, population growth is fastest among low wealth, Least Developed Countries. The UN projects a world population of 9.15 billion in 2050, which is a 32.69% increase from 2010 6.89 billion.

                                               

Ecumene

The ecumene or oecumene was an ancient Greek term for the known, the inhabited, or the habitable world. Under the Roman Empire, it came to refer to civilization as well as the secular and religious imperial administration. In present usage, it is most often used in the context of "ecumenical" and describes the Christian Church as a unified whole, or the unified modern world civilization. It is also used in cartography to describe a type of world map used in late Antiquity and the Middle Ages.

                                               

Global brain

The global brain is a neuroscience-inspired and futurological vision of the planetary information and communications technology network that interconnects all humans and their technological artifacts. As this network stores ever more information, takes over ever more functions of coordination and communication from traditional organizations, and becomes increasingly intelligent, it increasingly plays the role of a brain for the planet Earth.

                                               

Global change

Global change refers to planetary-scale changes in the Earth system. The system consists of the land, oceans, atmosphere, polar regions, life, the planets natural cycles and deep Earth processes. These constituent parts influence one another. The Earth system now includes human society, so global change also refers to large-scale changes in society. More completely, the term "global change" encompasses: population, climate, the economy, resource use, energy development, transport, communication, land use land cover, urbanization, globalization, atmospheric circulation, ocean circulation, the carbon cycle, the nitrogen cycle, the water cycle and other cycles, sea ice loss, sea-level rise, food webs, biological diversity, pollution, health, over fishing, and more.

                                               

Global commons

Global commons is a term typically used to describe international, supranational, and global resource domains in which common-pool resources are found. Global commons include the earths shared natural resources, such as the high oceans, the atmosphere and outer space and the Antarctic in particular. Cyberspace may also meet the definition of a global commons.
