This method can be used for virtually indefinite storage of material without deterioration over a much greater time-period relative to all other methods of ex situ conservation. Cryopreservation is also used for the conservation of livestock genetics through cryoconservation of animal genetic resources .
Remediation technologies are many and varied but can generally be categorized into ex-situ and in-situ methods. Ex-situ methods involve excavation of affected soils and subsequent treatment at the surface as well as extraction of contaminated groundwater and treatment at the surface. In-situ methods seek to treat the contamination without ...
Bioremediation techniques can be classified as (i) in situ techniques, which treat polluted sites directly, vs (ii) ex situ techniques which are applied to excavated materials. [8] In both these approaches, additional nutrients, vitamins, minerals, and pH buffers are added to enhance the growth and metabolism of the microorganisms.
It involves the application of science and technology in the process of addressing environmental challenges through environmental conservation and the mitigation of human impact to the environment. The term is sometimes also used to describe sustainable energy generation technologies such as photovoltaics , wind turbines , etc. [ citation needed ]
Some endangered species in the country were reintroduced via ex situ conservation. Ex situ conservation is rearing or cultivating, including reintroducing, a plant or animal outside their natural habitat. The reintroduction of the Indian rhinoceros at the Dudhwa National Park was a form of ex situ conservation; it
Indirect methods include track stations, fecal counts, food removal, open or closed burrow-opening counts, burrow counts, runaway counts, knockdown cards, snow tracks, or responses to audio calls. [52] For large, terrestrial vertebrates, a popular method is to use camera traps for population estimation along with mark-recapture techniques.
In 2005, economic losses (mainly from air pollution) were calculated at 7.7% of China's GDP. This grew to 10.3% by 2002 and the economic loss from water pollution (6.1%) began to exceed that caused by air pollution. [18] China has been one of the top performing countries in terms of GDP growth (9.64% in the past ten years). [18]
Nevertheless, in many cases research is focused on the extraction of soil and water and its ex situ biological treatment to avoid these problems. [4] Finally, the potential of GMOs is limited by regulatory agencies in terms of responsibility and bioethical issues. Their release require support on the action zone and comparability with ...
