what is the definition of man made environment
Built environment In social science, the term built environment, or built world, refers to the human-made surroundings that provide the setting for human activity, ranging in scale from buildings to parks. It has been defined as "the human-made space in which people live, work, and recreate on a day-to-day basis."[1] The "built environment encompasses places and spaces created or modified by people including buildings, parks, and transportation systems." In recent years,[when?] public health research has expanded the definition of "built environment" to include healthy food access, community gardens, mental health,[2][3] "walkability", and "bikeability".[4]
Human impact on the environment Human impact on the environment or anthropogenic impact on the environment includes changes to biophysical environments[1] and ecosystems, biodiversity, and natural resources[2][3] caused directly or indirectly by humans, including global warming,[1][4] environmental degradation[1] (such as ocean acidification[1][5]), mass extinction and biodiversity loss,[6][7][8][9] ecological crises, and ecological collapse. Modifying the environment to fit the needs of society is causing severe effects, which become worse as the problem of human overpopulation continues.[10] Some human activities that cause damage (either directly or indirectly) to the environment on a global scale include human reproduction,[11] overconsumption, overexploitation, pollution, and deforestation, to name but a few. Some of the problems, including global warming and biodiversity loss pose an existential risk to the human race,[12][13] and overpopulation causes those problems.[14][15]
Montreal Protocol "Recognizing that worldwide emissions of certain substances can significantly deplete and otherwise modify the ozone layer in a manner that is likely to result in adverse effects on human health and the environment. Determined to protect the ozone layer by taking precautionary measures to control equitably total global emissions of substances that deplete it with the ultimate objective of their elimination on the basis of developments in scientific knowledge"
Town A town is a human settlement. Towns are generally larger than villages but smaller than cities, though the criteria to distinguish them vary considerably between different parts of the world.
