Novel ecosystems are part of the human environment and niche (including urban, suburban, and rural), they lack natural analogs, and they have extended an influence that has converted more than three-quarters of wild Earth [citation needed].
Vegetation associations on old buildings or along field boundary stone walls in old agricultural landscapes are examples of sites where research into novel ecosystem ecology is developing.
These new systems involve new, powerful energy sources (fossil and atomic fuels), technology, money, and cities that have little or no parallels in nature.
On a more local scale, abandoned lots, agricultural land, old buildings, field boundary stone walls or residential gardens provide study sites on the history and dynamics of ecology in novel ecosystems.
[22]: 445 Ellis (2008)[22] identifies twenty-one different kinds of anthropogenic biomes that sort into the following groups: 1) dense settlements, 2) villages, 3) croplands, 4) rangeland, 5) forested, and 6) wildlands.
[24] The word is derived from the Greek νοῦς (nous "mind") + σφαῖρα (sphaira "sphere"), in lexical analogy to "atmosphere" and "biosphere".
"[29] The weight of Earth's technosphere has been suggested to be 30 trillion tons, a mass greater than 50 kilos for every square metre of the planet's surface.
Technoecosystems have far greater energy requirements than natural ecosystems, excessive water consumption, and release toxic and eutrophicating chemicals.
Because of the adverse impacts of the latter and the great human pressures on bio-ecotopes, they are even antagonistically related and therefore cannot function together as a coherent, sustainable ecological system.
