Hlau yog qhov tseeb ib puag ncig ntawm cov khoom ntim. Nws tsis ruaj khov los ntawm lwm cov khoom ntim rau ntawm kev siv cov khoom siv pov tseg, kev siv nyab xeeb, txuag nqi, rov ua dua tshiab thiab qhov tsawg kawg nkaus ntawm kev siv cov khoom siv. Cov yam ntxwv ib puag ncig ntawm cov hlau yog feem ntau tsis quav ntsej los ntawm cov tuam txhab uas dig muag cov neeg sib tw los nyiam cov neeg siv' mloog, tab sis nws yog qhov khoom ntim tau ruaj khov tiag tiag.
Txo qhov hnyav-pom qhov nqaim?
Lub hom phiaj ntawm kev txo qhov hnyav yog ib feem ntawm" Kotod Cog Lus", vim tias txo qhov hnyav ntawm kev ntim khoom tuaj yeem txo cov pa roj carbon dioxide thaum lub sijhawm pov tseg. Cov qauv no tuaj yeem ua tiav tsoomfwv' s lub hom phiaj kev tiv thaiv ib puag ncig. Tsis muaj kev tsis lees paub tias qhov txheej txheem no yog yooj yim thiab to taub yooj yim.
