Ukunukubezeka komoya kungomunye wemiphumela elimaza kakhulu kodwa enganakwa yokulima kwezilwane ezimbonini. I-Concentrated Animal feeding operations (CAFOs) ikhiphela inqwaba yamagesi ayingozi njenge-ammonia, i-methane, ne-hydrogen sulfide emkhathini, kudala ubungozi obungathi sína kokubili kwemvelo nempilo yabantu. Lokhu kukhishwa akugcini nje ukufaka isandla ekungazinzi kwesimo sezulu kodwa futhi kuthinta imiphakathi yendawo, okuholela ezifweni zokuphefumula, izinkinga zenhliziyo, nezinye izimo zezempilo zesikhathi eside.
Imfucumfucu ekhiqizwa izigidi zezigidi zezilwane ezivalekile—evame ukugcinwa emachwebeni amakhulu noma esakazwa njengomanyolo owuketshezi—ikhipha izinto eziphilayo ezishintshashintshayo kanye nezinhlayiyana ezincane ezehlisa umoya. Abasebenzi kanye nezakhamuzi eziseduze bathinteka ngendlela engalingani, babhekana nokuchayeka nsuku zonke ezinto ezingcolisa umoya ezinobuthi ezibeka engcupheni izinga lempilo kanye nokwandisa ukukhathazeka kobulungiswa bezemvelo. Ukwengeza, ukukhishwa kwe-methane okuvela emfuyweni kungenye yezinto ezinamandla kakhulu emazingeni okushisa komhlaba, okuqinisa ukuphuthuma kokubhekana nalolu daba.
Lesi sigaba sigqamisa ukuxhumana okungenakuhlukaniswa phakathi kokulima kwasefekthri nokuwohloka kwekhwalithi yomoya. Ukuguqukela ezinhlelweni zokudla ezisimeme, ukunciphisa ukuthembela emikhiqizweni yezilwane ezimbonini, kanye nokwamukela izindlela zokulima ezihlanzekile kuyizinyathelo ezibalulekile zokunciphisa ukungcoliswa komoya. Ukuvikela umoya esiwuphefumulayo akuyona nje indaba yomthwalo wemvelo kodwa futhi namalungelo abantu nempilo yomphakathi yomhlaba wonke.
Ukulima efektri, indlela ethuthukile nenqwaba yokukhulisa izilwane ukukhiqizwa kokudla, sekuyinto ebalulekile yemvelo. Inqubo yezilwane ezikhiqiza ngobuningi zokudla ayikhuphuki kuphela imibuzo yokuziphatha ngenhlalonhle yezilwane kodwa futhi inomthelela omubi emhlabeni. Nawa amaqiniso ayi-11 abalulekile mayelana namapulazi efektri kanye nemiphumela yawo yezemvelo: Amapulazi awo angu-1- abamba amanzi aphuma efektri angomunye wabahlinzeki abaholayo ekuphumeni kwamagesi abamba ukushisa abamba ukushisa, ekhulula amanani amakhulu we-methane ne-nitrous oxide emkhathini. Lawa magesi anamandla amakhulu kune-carbon dioxide endimeni yawo ekushiseni komhlaba, nge-methane eneminyaka engaba ngu-28 ephumelela kakhudlwana ekushiseni ukushisa kweminyaka engu-100, futhi i-nitrous oxide cishe ama-298 amahlandla angama-298. Umthombo oyinhloko wokukhishwa kwe-methane epulazini efektri uvela ezilwaneni ezihlubukayo, njengezinkomo, izimvu nezimbuzi, ezikhiqiza inqwaba ye-methane ngesikhathi sokugaya ...
