Vim tias qhov tshwj xeeb ntawm nws kev tsim khoom thiab kev ua haujlwm, cov tshuab luam ntawv siv los ua ib qho uas cuam tshuam rau ib puag ncig. Tam sim no, nrog kev txhim kho ntawm social science thiab thev naus laus zis, cov ntawv luam ntawv kuj tau dhau los ua&tshiab "knight &"; ntawm kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig, ua rau kev txuag hluav taws xob thiab kev tiv thaiv ib puag ncig. Raws li txoj kev txhim kho tshiab ntawm cov tshuab luam ntawv, tshuab luam ntawv kuj tseem yuav muaj chaw txhim kho tshiab.
Lub tshuab luam ntawv muaj qee yam khoom tiv thaiv ib puag ncig. Piv txwv li, nws tuaj yeem txo qis cov organic sib txuas uas tsim los ntawm txheej txheem luam ntawv, ib yam khoom uas tuaj yeem rhuav tshem lub ntiaj teb' txheej ozone thiab ua rau lub ntiaj teb sov tuaj. Cov tshuab luam ntawv tseem tuaj yeem txuag cov peev txheej dej. Cov txheej txheem luam ntawv ib txwm xav tau dej los ua cov txheej txheem luam ntawv thiab tsim kom muaj cov txheej txheem ua kom qhuav. Txoj kev luam ntawv tsis muaj dej tshiab tsuas yog zam kev pov tseg cov peev txheej dej. Cov ntawv uas siv kuj tseem poob qis, ua kom lub zog txuag.
