Kabon dayɔgzayd (CO2) na wan gas we de mek di wɔl wam ɛn na wan pan di men tin dɛn we de mek di klaymat chenj. Insay dis, wan prɔses we dɛn kɔl “artificial photosynthesis (CO2 photoreduction)” kin mek ɔrganik fidstɔk fɔ fiul ɛn kemikal frɔm CO2, wata ɛn solar ɛnaji, jɔs lɛk aw plant dɛn kin du. Na di sem tɛm, dɛn kin ridyus di CO2 we dɛn kin pul bak, bikɔs dɛn kin yuz CO2 as fidstɔk fɔ mek dɛn prodyuz ɛnaji ɛn kemikal risɔs. So, dɛn kin tek atifishal fotosintesis as wan pan di laytst grɛn teknɔlɔji dɛn.
