Zoo Siab
Covhnyav kev lag luam yog cov haujlwm uas tsim khoomcov khoom ua tiav ib nrab, uas tom qab ntawd ua haujlwm li cov khoom lag luam peev rau kev tsim khoom tom ntej ntawm lwm cov khoom lag luam npaj rau kev siv los ntawm tib neeg.
Cov txheej txheem tsim khoom hauv kev lag luam hnyav yog, ntau zaus, zoo ib yam li uas tau mob siab rau kev rho tawm thiab hloov pauv ntawm Cov Khoom Raw hauv cov tshuab tsim nyog rau kev tsim khoom.
Tsis ntseeg, lub xyoo pua puas xyoo yog ib qho uas ua rau muaj kev nce qib loj tshaj plaws hauv keeb kwm nrog kev hwm rau kev lag luam. Qhov pib ntawm cov txheej txheem kev hloov pauv tau tshwm sim hauv cov chaw nyob deb nroog thiab nws tau nthuav dav tsis tu ncua mus rau feem ntau hauv nroog hauv Europe, tab sis tsis ntseeg tias nws muaj kev nthuav dav nthuav tawm los ntawm kev ua raws li hlau raws li cov khoom siv, hloov qee lub sijhawm tom qab los ntawm hlau uas yog cov hlau uas ua ke cov hlau nrog cov pa roj carbon thiab lwm yam.
Great Britain yog lub tebchaws uas sawv tawm feem ntau hauv cov txheej txheem kev tsim kho no, thiab suav nws tus kheej ua tus tsim cov hlau thiab cov thee: qhov no tau muab nws lub luag haujlwm tseem ceeb ntawm lub taub hau ntawm kev lag luam hnyav thoob ntiaj teb.
Cov cov teb chaws tsim khoom, tab sis tshwj xeeb tshaj yog cov uas tau ua ntej ntawm kev nce qib hauv kev lag luam hnyav, muaj qhov sib piv tau zoo heev thiab xaus kev xa tawm lawv cov khoom lag luam thiab lawv cov txuj ci mus rau thoob ntiaj teb. Txij thaum ntawd mus txog thaum kev sib sau ua ke ntawm thev naus laus zis thiab kev suav, muaj peev xwm ua lag luam hnyav txhais tau tias yog ua ntej ntawm kev lag luam thoob ntiaj teb.
Txawm li cas los xij, kev lag luam hnyav muaj qee tus yam ntxwv uas ua rau nws nyuaj dua li kev lag luam teeb. Cov khoom lag luam uas nws tsim los tsim los tsim lwm cov khoom lag luam, yog li tsis muaj cov yam ntxwv cuam tshuam nrog kev pom ntawm cov khoom lag luam uas siv tau ntawm no: nws yog ib txwm muaj rau cov khoom lag luam hnyav tsis muaj xim ntau dhau lossis ntxim nyiamHloov chaw, cov tuam txhab tsim khoom mob siab rau tag nrho lawv lub peev xwm ntawm kev ua kom zoo ntawm cov tshuab tsim.
Vim yog cov txheej txheem tsim khoom ntawm kev lag luam hnyav, nws yog qhov raug qhov no yam kev lag luam tsim rov qab qee yam pov tseg uas yog teeb meem loj heev rau ib puag ncig uas nyob ib puag ncig lub cev qhov chaw nws tshwm sim: cov chaw tsim khoom feem ntau tshem tawm ntau hom roj cua uas tsim kev puas tsuaj rau huab cua (pa phem), lossis feem ntau lawv muaj pov tseg uas lawv ntiab mus rau hauv pas dej lossis dej ntws (dej tsis huv), hnyav hnyav rau ib puag ncig.
Qhov no yog vim li cas kev lag luam hnyav feem ntau nyob hauv cheeb tsam theej cais los ntawm cov nroog loj, qhov twg tsawg tus neeg nyob thiab feem ntau ntawm cov neeg uas nyob ntawd ua nws tsuas yog nruab hnub.
Kev lag luam hnyav tsis yog siv zog ntau, thiab cov neeg ua haujlwm kuj tseem tuaj yeem nthuav tawm ntau hom kev qias neeg uas raug ntiab tawm ntawm qhov ntawd (Saib: cov pa phem). Yog tias tsoomfwv sim tswj cov qib kev ua qias tuaj no los ntawm kev cai lij choj, cov tuam txhab feem ntau sib cav tias qhov haujlwm yuav tsum tsis muab cov nyiaj tau los thiab tom qab ntawd lawv yuav tsum kaw nws, nthuav tawm txoj haujlwm ntawm cov neeg ua haujlwm.
Lub Xeev tseem muaj txiaj ntsig ntawm qib kev lag luam loj ntawm kev lag luam hnyav, txij li cov khoom tsim tawm tshwj xeeb yog kim thiab thaum xa tawm, lawv tsim kev muaj zog txaus ntawm cov nyiaj txawv teb chaws mus rau lub tebchaws, thiab siab dua txhua qhov peev xwm rau kev tsim khoom lag luam yam tsis tau nthuav tawm mus rau qhov xwm txheej ntawm kev xav tau ntshuam cov khoom zoo li no.
