Cov ntim khoom rov ua dua thiab rov siv tau yog ib qho ntawm cov kev daws teeb meem ruaj khov uas ntau tus neeg muag khoom muab. Cov ntim khoom rov ua dua thiab rov siv tau txhais tau tias cov neeg siv khoom tuaj yeem hloov lub raj mis sab hauv thiab muab tso rau hauv lub raj mis tshiab. Vim tias nws tau tsim los rau kev ntim khoom rov siv tau, nws txo cov khoom siv, kev siv hluav taws xob thiab cov pa roj carbon uas xav tau hauv cov txheej txheem tsim khoom.
Siv tau dua tshiab
Muaj ib qho kev hloov pauv loj hlob mus rau kev siv cov khoom xyaw rov ua dua tshiab hauv cov ntim khoom kom zoo nkauj.

Cov ntim khoom zoo rau ib puag ncig no ntxiv rau qhov kev hloov pauv rov ua dua tshiab.
Zuag qhia tag nrho, thaum cov neeg siv khoom txhawj xeeb ntau ntxiv txog ib puag ncig thaum muaj kev cuam tshuam ntawm tus kab mob sib kis, ntau thiab ntau lub npe lag luam tab tom tig mus rau kev ntim khoom uas ruaj khov, rov ua dua tshiab thiab rov ua dua tshiab.
