Anthropogenic

	Anthropogenic Anthropogenic ("human" + "generating") is an adjective that may refer to: * Anthropogeny, the study of the origins of humanity Counterintuitively, anthropogenic may also refer to things that have been generated by humans, as follows: * Human impact on the environment, i.e. anthropogenic impact on the environment Anthropogenic biome Anthropogenic climate change, human-caused global warming and its effects Anthropogenic cloud Anthropogenic greenhouse gases Anthropogenic hazard Anthropogenic metabolism Anthropogenic metabolism, also referred to as metabolism of the anthroposphere, is a term used in industrial ecology, material flow analysis, and waste management to describe the material and energy turnover of human society. It emerges from the ap ... {{disambiguation ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Anthropogenic Biome Anthropogenic biomes, also known as anthromes, human biomes or intensive land-use biome, describe the terrestrial biosphere (biomes) in its contemporary, human-altered form using global ecosystem units defined by global patterns of sustained direct human interaction with ecosystems. Origin and evolution of the concept Anthromes were first named and mapped by Erle Ellis and Navin Ramankutty in their 2008 paper, "Putting People in the Map: Anthropogenic Biomes of the World". Anthrome maps now appear in numerous textbooks. and in the National Geographic World Atlas. The most recent version oanthrome mapswere published in 2021. In a recent global ecosystem classification, the anthropogenic biomes has been incorporated into several distinct functional biomes in the terrestrial and freshwater realms, and additional units have been described for the freshwater, marine, subterranean and transitional realms to create a more comprehensive description of all ecosystems created and maintai ...

picture info	Climate Change 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 increase 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. Due to climate change, deserts are expanding, while heat waves and wildfires are becoming more common. Increased warming in the Arctic has contributed to melting permafrost, glacial retreat and sea ice loss. Higher temperatures are also causing m ...

picture info	Anthropogenic Hazard Anthropogenic hazards are hazards caused by human action or inaction. They are contrasted with natural hazards. Anthropogenic hazards may adversely affect humans, other organisms, biomes, and ecosystems. They can even cause an omnicide. The frequency and severity of hazards are key elements in some risk analysis methodologies. Hazards may also be described in relation to the impact that they have. A hazard only exists if there is a pathway to exposure. As an example, the center of the earth consists of molten material at very high temperatures which would be a severe hazard if contact was made with the core. However, there is no feasible way of making contact with the core, therefore the center of the earth currently poses no hazard. Anthropogenic hazards can be grouped into societal hazards (criminality, civil disorder, terrorism, war, industrial hazards, engineering hazards, power outage, fire), hazards caused by transportation and environmental hazards. Societal hazards ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	Anthropogeny Anthropogeny is the study of human origins. It is not simply a synonym for human evolution by natural selection, which is only a part of the processes involved in human origins. Many other factors besides natural selection were involved, ranging over climatic, geographic, ecological, social, and cultural ones. Anthropogenesis, meaning the process or point of becoming human, is also called hominization. History of usage The term ''anthropogeny'' was used in the 1839 edition of Hooper's ''Medical Dictionary'' and was defined as "the study of the generation of man". The term was popularized by Ernst Heinrich Haeckel (1834–1919), a German naturalist and zoologist, in his groundbreaking books, ''Natural History of Creation'' (German: ''Natürliche Schöpfungsgeschicht'') (1868) and ''The Evolution of Man'' (German: ''Anthropogenie'') (1874). Haeckel was one of the first biologists to publish on evolution. Haeckel used the term Anthropogeny to refer to the study of comparative embr ...

picture info	Human Impact On The Environment Human impact on the environment (or anthropogenic impact) refers to changes to biophysical environments and to ecosystems, biodiversity, and natural resources caused directly or indirectly by humans. Modifying the environment to fit the needs of society is causing severe effects including global warming, environmental degradation (such as ocean acidification), mass extinction and biodiversity loss, ecological crisis, and ecological collapse. Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include population growth, overconsumption, overexploitation, pollution, and deforestation. Some of the problems, including global warming and biodiversity loss, have been proposed as representing catastrophic risks to the survival of the human species. The term ''anthropogenic'' designates an effect or object resulting from human activity. The term was first used in the technical sense by Russian geologist Alexey Pavlov, and it w ...

picture info	Anthropogenic Cloud A homogenitus, anthropogenic or artificial cloud is a cloud induced by human activity. Although most clouds covering the sky have a purely natural origin, since the beginning of the Industrial Revolution, the use of fossil fuels and water vapor and other gases emitted by nuclear, thermal and geothermal power plants yield significant alterations of the local weather conditions. These new atmospheric conditions can thus enhance cloud formation. Various methods have been proposed for creating and utilizing this weather phenomenon. Experiments have also been carried out for various studies. For example, Russian scientists have been studying artificial clouds for more than 50 years. But by far the greatest number of anthropogenic clouds are airplane contrails (condensation trails) and rocket trails. Anthropogenesis Three conditions are needed to form an anthropogenic cloud: # The air must be near saturation of its water vapor, # The air must be cooled to the dew point temperature wi ...

picture info	Anthropogenic Greenhouse Gases Greenhouse gas emissions from human activities strengthen the greenhouse effect, contributing to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest emitters include coal in China and large oil and gas companies, many state-owned by OPEC and Russia. Human-caused emissions have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but it was consistent among all greenhouse gases (GHG). Emissions in the 2010s averaged 56 billion tons a year, higher than ever before. Electricity generation and transport are major emitters; the largest single source, according to the United States Environmental Protection Agency, is transportation, accounting for 27% of all USA greenhouse gas emissions. Deforestation and other changes in land use also emit carbon dioxide and methane. The largest source of anthropogenic methane emissions is agriculture, closely followed by ...
