Imihlaba iyakwazi ukugcina ikhabhoni esemoyeni. Ke ngoko, banokuba sisixhobo esibaluleke kakhulu kumlo ochasene notshintsho lwemozulu. Umbutho woKutya nezoLimo weZizwe eziManyeneyo (i-FAO) kubonisiwe kwi Usuku lomhlaba wehlabathi, ukonyusa indima yomphezulu "kungaluphelisa ukwanda ngokukhawuleza kwekhabhon dayoksayidi kwiatmosfera."
Zeziphi iimpembelelo ezinokuba nazo emhlabeni kutshintsho lwemozulu?
Ukuhanjiswa kwekhabhoni yendalo
Xa sithetha malunga nokukhutshwa kwegesi eluhlaza kwindalo esesibhakabhakeni, asinakuyibetha ngoyaba into yokuba kukho iisinki zekhabhoni ezisasazwe kwiplanethi yonke. Siqala ngezityalo. Ezi ziyakwazi ukugcina ikhabhoni ngexesha lenkqubo yefotosinthesis, Ke ngoko, yonke ikhabhon abayisebenzisela yona ayibuyiselwanga kumoya womoya.
Kwelinye icala, sinolwandle. Ikhabhoni yaziswa kubo kwaye yalungiswa kwi-substrate, ishiya ngokupheleleyo umjikelo wekhabhoni. Oku kuthetha ukuba ikhabhoni ayinakufakwa kwakhona kwi-atmosferi kwaye, ke, iyanciphisa inani lekhabhoni kuyo enokugcina ubushushu.
Okokugqibela, kukho imigangatho. Imigangatho yehlabathi lonke bayakwazi ukufaka ikhabhoni okusemoyeni kwaye ukuguqula kube zizondlo zezityalo nezinto eziphilayo. Ndiyabulela koku, imihlaba inokuba sisixhobo esilungileyo kumlo ochasene notshintsho lwemozulu.
Imephu yehlabathi yekhabhoni
Ukwazi iindawo zehlabathi apho imihlaba efunxa eyona khabhoni isasazwayo, kwenziwe imephu enoxinaniso lwayo. Ukuza kuthi ga ngoku Imephu yeHlabathi yoMhlaba weCarbon Organic ibonisa ukuba iindawo zendalo zehlabathi ezikwaziyo ukubamba eyona khabhon kufuneka zikhuselwe.
Ngokucacileyo, ayinguye wonke umhlaba okwaziyo ukugcina umlinganiselo ofanayo wekhabhoni. Kuxhomekeka kuhlobo lomhlaba kunye neemeko owenziwe ngazo umhlaba, ezinye ziyakwazi ukubamba ngaphezulu kunezinye. Ukuba ezo ndawo zinokugcina ikhabhon engaphezulu zikhuselwe kulwakhiwo, ezolimo, imfuyo okanye naluphi na uhlobo lomsebenzi oguqula ukusetyenziswa komhlaba, unokusetyenziswa njengesixhobo ukunciphisa ifuthe lotshintsho. Imozulu.
Kufuneka kuthathelwe ingqalelo ukuba, ubuncinci beegesi zegreenhouse ezikhoyo emoyeni, ukugcinwa kobushushu kancinci. Ngaphaya koko, ukuba siyabulela kunyuso lwamandla ahlaziyekayo, sinciphisa ukukhutshwa, siza kuhlasela le nto kumacala amabini.
Iziphumo zokonakaliswa komhlaba
Ngenxa yotshintsho ekusetyenzisweni komhlaba kunye nokonakaliswa nokuthotywa kwesinye kwisithathu somhlaba, inyuse isixa esikhulu sekhabhoni ekhutshelwe emoyeni.
Ukunciphisa le ngxaki, ukubuyiselwa komhlaba kunokunceda ukususa ukuya kwi-63.000 yeetoni zekhabhoni emoyeni. Oku kunganegalelo elibonakalayo kumlo ochasene notshintsho lwemozulu. Imaphu ekhankanywe ngasentla yayilwa kumsitho weSuku loMhlaba loMhlaba kwaye ibonisa ukuba kwihlabathi liphela iisentimitha ezingama-30 zokuqala zomphezulu ziqulathe malunga nezigidi ezingama-680.000 zeetoni zekhabhoni, phantse iphindwe kabini into ekhoyo emoyeni.
I-60% yeetoni Ifumaneka eRashiya, Canada, United States, China, Brazil, Indonesia, Australia, Argentina, Kazakhstan nase Democratic Republic of the Congo. Ke ngoko, amanyathelo kufuneka enziwe ukukhusela loo mihlaba ikwaziyo ukugcina ikhabhon engaphezulu kwaye kuthintelwe ukukhutshwa okungakumbi emoyeni.
Uncedo olukhulu lokuthathela ingqalelo kukuba imihlaba etyebileyo kwikhabhon inemveliso ngakumbi kwaye inakho ukucoca amanzi ngcono, inika izityalo iimeko ezifanelekileyo zokufuma.
Njengoko ubona, imihlaba sisixhobo esihle sokunciphisa ifuthe lokutshintsha kwemozulu kwaye kubalulekile ukukhuthaza ulondolozo lwayo.
