Inhlabathi iyakwazi ukugcina ikhabhoni esemoyeni. Ngakho-ke, zingaba yisikhali esibaluleke kakhulu ekulweni nokuguquka kwesimo sezulu. Inhlangano Yezokudla Nezolimo yeNhlangano Yezizwe (i-FAO) ikhonjiswe ku Usuku Lomhlaba Lomhlabathi, ukuthi ukwandisa indima yendawo "kungasusa ngokuphawulekayo ukwanda okusheshayo kwesikhutha emkhathini."
Ungaba namiphi imiphumela emhlabathini ekushintsheni kwesimo sezulu?
Ukusatshalaliswa kwekhabhoni
Uma sikhuluma ngokukhishwa kwegesi engcolisa ukushisa emkhathini, asikwazi ukungakunaki iqiniso lokuthi kukhona amasinki ekhabhoni asatshalaliswa emhlabeni wonke. Siqala ngezitshalo. Lokhu kuyakwazi ukugcina ikhabhoni ngesikhathi senqubo ye-photosynthesis, ngakho-ke, yonke ikhabhoni abayisebenzisela yona ayibuyiselwe emkhathini.
Ngakolunye uhlangothi, sinolwandle. I-Carbon ingeniswa kubo futhi ilungiswe ku-substrate, ishiya ngokuphelele umjikelezo wekhabhoni. Lokhu kusho ukuthi ikhabhoni ayinakufakwa futhi emoyeni futhi, ngakho-ke, inciphisa inani lekhabhoni elikuyo elingagcina ukushisa.
Ekugcineni, kukhona phansi. Phansi kwawo wonke umhlaba bayakwazi ukufaka i-carbon okusemkhathini bese ukuguqula kube izakhamzimba zezitshalo nezinto eziphilayo. Ngenxa yalokhu, inhlabathi ingaba ithuluzi elihle ekulweni nokuguquka kwesimo sezulu.
Imephu yomhlaba weCarbon
Ukuze wazi izindawo zomhlaba lapho kusatshalaliswa khona inhlabathi emunca isikhutha esiningi, kwenziwe imephu ngokugxila kwayo. Kuze kube manje i- Imephu Yomhlaba We-Organic Carbon kukhombisa ukuthi izindawo zemvelo zomhlaba ezikwaziyo ukugcina ikhaboni kakhulu kumele zivikelwe.
Ngokusobala, akuyona yonke inhlabathi ekwaziyo ukugcina inani elifanayo lekhabhoni. Ngokuya ngohlobo lomhlabathi nezimo okwakhiwe ngazo inhlabathi, ezinye ziyakwazi ukubamba ngaphezu kwezinye. Uma lezo zindawo ezikwazi ukugcina i-carbon eningi zivikelekile ekwakhiweni, kwezolimo, emfuyweni noma kunoma yiluphi uhlobo lomsebenzi oluguqula ukusetshenziswa komhlaba, ingasetshenziswa njengesikhali ukunciphisa imiphumela yoshintsho isimo sezulu.
Kumele kucatshangwe ukuthi, inani elincane lamagesi abamba ukushisa akhona emoyeni, ukugcinwa okuncane kokushisa. Ngaphezu kwalokho, uma, ngenxa yokukhuthazwa kwamandla avuselelekayo, sinciphisa ukukhishwa, sizobe sihlasela lesi simo kusuka ezinhlangothini ezimbili.
Imiphumela yokucekelwa phansi kwenhlabathi
Ngenxa yokushintsha kokusetshenziswa komhlaba nokucekelwa phansi nokonakala kwengxenye eyodwa kwezintathu zenhlabathi yomhlaba, kudale inani elikhulu lekhabhoni elikhishelwe emoyeni.
Ukwehlisa le nkinga, ukubuyiswa kwenhlabathi kungasiza ukususa amathani afinyelela kuma-63.000 ekhabhoni emkhathini. Lokhu kungaba nomthelela omkhulu ekulweni nokuguquka kwesimo sezulu. Imephu eshiwo ngenhla yaklanywa ngesikhathi seSuku Lomhlaba Lomhlaba futhi ikhombisa ukuthi emhlabeni wonke amasentimitha okuqala angama-30 womhlaba aqukethe cishe amathani ayizigidi eziyizinkulungwane ezingama-680.000 kabhoni, cishe iphindwe kabili leyo ekhona emkhathini.
Ama-60% alawo mathani Itholakala eRussia, eCanada, e-United States, eChina, eBrazil, e-Indonesia, e-Australia, e-Argentina, e-Kazakhstan naseDemocratic Republic of the Congo. Ngakho-ke, kufanele kwenziwe izinyathelo zokuvikela leyo nhlabathi ekwaziyo ukugcina ikhaboni eningi futhi igweme ukukhishwa okuningi emkhathini.
Inzuzo enkulu okufanele uyikhumbule ukuthi inhlabathi ecebe kakhulu ngekhabhoni ikhiqiza kakhulu futhi iyakwazi ukuhlanza amanzi kangcono, inikeze izitshalo izimo ezifanele zomswakama.
Njengoba ukwazi ukubona, inhlabathi iyithuluzi elihle lokunciphisa imiphumela yokuguquka kwesimo sezulu futhi kubalulekile ukukhuthaza ukongiwa kwayo.
