World Population
In demographics of the world, world demographics, the world population is the total number of humans currently alive. It was estimated by the United Nations to have exceeded eight billion in mid-November 2022. It took around 300,000 years of human prehistory and human history, history for the human population to reach a billion and only 218 more years to reach 8 billion. The human population has experienced Population growth, continuous growth following the Great Famine of 1315–1317 and the end of the Black Death in 1350, when it was nearly 370,000,000. The highest global List of countries by population growth rate, population growth rates, with increases of over 1.8% per year, occurred between 1955 and 1975, peaking at 2.1% between 1965 and 1970. The growth rate declined to 1.1% between 2015 and 2020 and is projected to decline further in the 21st century. The global population is still increasing, but there is significant uncertainty about its long-term trajectory due ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World Population Prospects
Human population projections are attempts to extrapolate how human populations will change in the future. These projections are an important input to forecasts of the population's impact on this planet and humanity's future well-being. Models of population growth take trends in human development and apply projections into the future. These models use trend-based-assumptions about how populations will respond to economic, social and technological forces to understand how they will affect fertility and mortality, and thus population growth. The 2022 projections from the United Nations Population Division (chart #1) show that annual world population growth peaked at 2.3% per year in 1963, has since dropped to 0.9% in 2023, equivalent to about 74 million people each year, and could drop even further to minus 0.1% by 2100. Based on this, the UN projected that the world population, 8 billion , would peak around the year 2084 at about 10.3 billion, and then start a slow decline, ass ...

Western Han
The Han dynasty was an imperial dynasty of China (202 BC9 AD, 25–220 AD) established by Liu Bang and ruled by the House of Liu. The dynasty was preceded by the short-lived Qin dynasty (221–206 BC) and a warring interregnum known as the Chu–Han Contention (206–202 BC), and it was succeeded by the Three Kingdoms period (220–280 AD). The dynasty was briefly interrupted by the Xin dynasty (9–23 AD) established by the usurping regent Wang Mang, and is thus separated into two periods—the Western Han (202 BC9 AD) and the Eastern Han (25–220 AD). Spanning over four centuries, the Han dynasty is considered a golden age in Chinese history, and had a permanent impact on Chinese identity in later periods. The majority ethnic group of modern China refer to themselves as the " Han people" or "Han Chinese". The spoken Chinese and written Chinese are referred to respectively as the "Han language" and " Han characters". ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ancient China
The history of China spans several millennia across a wide geographical area. Each region now considered part of the Chinese world has experienced periods of unity, fracture, prosperity, and strife. Chinese civilization first emerged in the Yellow River valley, which along with the Yangtze River, Yangtze basin constitutes the geographic core of the Sinosphere, Chinese cultural sphere. China maintains a rich diversity of ethnic and linguistic people groups. The Chinese historiography, traditional lens for viewing Chinese history is the Dynasties of China, dynastic cycle: imperial dynasties rise and fall, and are ascribed certain achievements. This lens also tends to assume Chinese civilization can be traced as an unbroken thread Five thousand years of Chinese civilization, many thousands of years into the past, making it one of the Cradle of civilization, cradles of civilization. At various times, states representative of a dominant Chinese culture have directly controlled areas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Pandemic
A pandemic ( ) is an epidemic of an infectious disease that has a sudden increase in cases and spreads across a large region, for instance multiple continents or worldwide, affecting a substantial number of individuals. Widespread endemic (epidemiology), endemic diseases with a stable number of infected individuals such as recurrences of seasonal influenza are generally excluded as they occur simultaneously in large regions of the globe rather than being spread worldwide. Throughout human history, there have been a number of pandemics of diseases such as smallpox. The Black Death, caused by the Plague (disease), Plague, caused the deaths of up to half of the population of Europe in the 14th century. The term ''pandemic'' had not been used then, but was used for later epidemics, including the 1918 Influenza A virus subtype H1N1, H1N1 influenza A pandemic—more commonly known as the Spanish flu—which is the Deadliest pandemics in history, deadliest pandemic in history.

Indian Subcontinent
The Indian subcontinent is a physiographic region of Asia below the Himalayas which projects into the Indian Ocean between the Bay of Bengal to the east and the Arabian Sea to the west. It is now divided between Bangladesh, India, and Pakistan. (subscription required) Although the terms "Indian subcontinent" and "South Asia" are often also used interchangeably to denote a wider region which includes, in addition, Bhutan, the Maldives, Nepal and Sri Lanka, the "Indian subcontinent" is more of a geophysical term, whereas "South Asia" is more geopolitical. "South Asia" frequently also includes Afghanistan, which is not considered part of the subcontinent even in extended usage.Jim Norwine & Alfonso González, ''The Third World: states of mind and being'', pages 209, Taylor & Francis, 1988, Quote: ""The term "South Asia" also signifies the Indian Subcontinent""Raj S.

Plague Of Justinian
The plague of Justinian or Justinianic plague (AD 541–549) was an epidemic of Plague (disease), plague that afflicted the entire Mediterranean basin, Mediterranean Basin, Europe, and the Near East, especially the Sasanian Empire and the Byzantine Empire. The plague is named for the Byzantine Emperor Justinian I (r. 527–565) who, according to his Court (royal), court historian Procopius, contracted the disease and recovered in 542, at the height of the epidemic which killed about a fifth of the population in the imperial capital Constantinople, Constantinople. The contagion arrived in Roman Egypt in 541, spread around the Mediterranean Sea until 544, and persisted in Northern Europe and the Arabian Peninsula until 549. By 543, the plague had spread to every corner of the empire. The plague's severity and impact remain debated. Some scholars assert that as the first episode of the first plague pandemic, it had profound economic, social, and political effects across Europe an ...

Toba Catastrophe Theory
The Toba eruption (also called the Toba supereruption and the Youngest Toba eruption) was a supervolcanic eruption that occurred around 74,000 years ago, during the Late Pleistocene, at the site of present-day Lake Toba, in Sumatra, Indonesia. It was the last in a series of at least four caldera-forming eruptions there, the earlier known caldera having formed about 1.2 million years ago. This, the last eruption, had an estimated volcanic explosivity index of 8, making it the largest known explosive volcanic eruption in the Quaternary, and one of the largest known explosive eruptions in the Earth's history. Eruption Chronology of the Toba eruption The exact date of the eruption is unknown, but the pattern of ash deposits suggests that it occurred during the northern summer because only the summer monsoon could have deposited Toba ashfall in the South China Sea. The eruption lasted perhaps 9 to 14 days. The most recent two high-precision argon–argon datings dated the erupt ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
