Bothata ba tšilafalo ea moea
Litsebi li lumela hore bothata bo boholo ba China ke mosi o chefo, o silafatsang sepakapaka. Mohloli o moholo ke ho tsoa ha carbon dioxide, e hlahisoang ke limela tsa motlakase tse chesang tsa naha tse sebetsang mashala. Ntle le moo, moea o mpefala ka lebaka la ts'ebeliso ea makoloi. Hape, metsoako e joalo le lintho li ntšetsoa sepakapakeng khafetsa:

Boemo ba metsi a ka tlasa lefatše ha se bona bo botle ka ho fetisisa: ts'ilafalo ea ona ke 90%. Mehloli ea tšilafalo

Bophahamo ba metsi a litšila a sa alafshoang a kenngoang sebakeng sa metsi a naha a hakanyetsoa ho limilione tse likete tsa lithane. Ho sena hoa hlaka hore mehloli e joalo ea metsi ha e tšoanelehe bakeng sa ho nooa feela, empa le bakeng sa ts'ebeliso ea lapeng. Ntlheng ena, bothata bo bong ba tikoloho bo hlaha - khaello ea metsi a nooang. Ntle le moo, batho ba sebelisang metsi a litšila ba tšoaroa ke mafu a matla, 'me maemong a mang, metsi a chefo a bolaea.
