Siyakwamukela kubhulogi yethu, lapho singena sijula emhlabeni wokusimama nokuqwashisa ngemvelo. Engosini yanamuhla, sizoxoxa ngesihloko esibalulekile: inani lemvelo lokudliwa kwenyama nobisi. Njengoba silwela ukwenza izinqumo eziqaphela kakhudlwana ekuphileni kwethu kwansuku zonke, kubalulekile ukuqonda umthelela imikhuba yethu yokudla enawo emhlabeni. Ngokukhethekile, sizohlola i-carbon footprint, ukusetshenziswa kwamanzi nokungcoliswa komhlaba, ukusetshenziswa komhlaba, nokugawulwa kwamahlathi okuhambisana nokusetshenziswa kwenyama nemikhiqizo yobisi.
I-Carbon Footprint Yenyama Nobisi
Ubuwazi ukuthi imboni yenyama neyobisi ibhekene nenani elikhulu lokukhishwa kwesisi esibamba ukushisa? Ukukhiqizwa kwemfuyo kunomthelela ekuguqukeni kwesimo sezulu ikakhulukazi ngokukhishwa kwe-methane okuvela ekuvubeleni kwe-enteric nokulawulwa komquba, kanye nokukhishwa kwe-carbon dioxide ekugawulweni kwamahlathi nokuhamba.
Lapho izilwane ezondlayo njengezinkomo nezimvu zigaya ukudla kwazo, zikhiqiza i-methane, igesi ebamba ukushisa enamandla. Le methane ikhishwa nge-flatulence kanye ne-belching, okunomthelela ekufudumaleni komhlaba. Ukwengeza, ukuphathwa komquba emisebenzini yokulima emikhakheni emikhulu nakho kukhulula inani elikhulu le-methane emkhathini.
Ngaphezu kwalokho, ukukhiqizwa, ukucubungula, kanye nokuthuthwa kwenyama nemikhiqizo yobisi kunomthelela ekukhishweni kwesikhutha. Ukugawulwa kwamahlathi, ngokuvamile okubangelwa isidingo somhlaba owengeziwe wokuhlalisa imfuyo noma ukutshalwa kwezitshalo zokudla kwezilwane, kukhipha inqwaba yesikhutha. Ukuthuthwa kwemikhiqizo yezilwane iye ezimakethe kwengeza nakuma-carbon footprint ayo.
Ngokunciphisa ukudla kwethu inyama nobisi noma ukukhetha ezinye izindlela ezisimeme, singehlisa kakhulu izinga lekhabhoni yethu futhi sisize ukulwa nokushintsha kwesimo sezulu.
Ukusetshenziswa Amanzi Nokungcola
Ukulima kwezilwane nakho kungumthengi omkhulu wemithombo yamanzi, okunomthelela ekuswelekeni kwamanzi ezingxenyeni ezihlukahlukene zomhlaba. Inani elikhulu lamanzi adingekayo ukuze kukhiqizwe ukudla kwezilwane liyamangaza. Ukwengeza, ukuphatha ubulongwe ngendlela engafanele kuholela ekungcoleni kwamanzi.
Ukondla imfuyo kudinga amanzi amaningi kakhulu. Ukukhulisa izitshalo ezinjengommbila noma ubhontshisi wesoya ukuze uphakele izilwane kudinga amanzi amaningi okunisela. Lesi sibalo esikhulu samanzi okukhiqiza ukudla kwezilwane sihumusha ukusetshenziswa kwamanzi okuphezulu embonini yenyama neyobisi.
Ukugeleza komquba kudala enye inkinga yokungcoliswa kwamanzi. Ukuphathwa ngendlela engafanele kanye nokulahlwa kwemfucuza yezilwane kungangcolisa imizimba yamanzi ngemisoco eyeqile, okuholela ekuqhumeni kwe-algal nezindawo ezifile, kulimaza imvelo yasemanzini.
Ngenxa yalezi zinkinga, kubalulekile ukugqugquzela izindlela zokulawula amanzi ngendlela eqhubekayo ekufuyweni kwemfuyo kanye nokubheka ezinye izindlela zokonga amanzi.
Ukusetshenziswa Komhlaba Nokugawulwa Kwamahlathi
Ukwandiswa kokulima kwezilwane kudinga imithombo ebanzi yomhlaba, ngokuvamile okuholela ekugawulweni kwamahlathi nokucekelwa phansi kwezindawo zokuhlala. Lokhu kubeka ingcindezi enkulu kuma-ecosystem futhi kunemiphumela emibi kakhulu yemvelo.
I-Pastureland and confined animal feeding operations (CAFOs) idinga inani elikhulu lomhlaba. Ukuguqulwa kwezindawo zemvelo zibe umhlaba wokulima kunomthelela ekulahlekeni kwezinhlobonhlobo zezinto eziphilayo futhi kuphazamisa ibhalansi yemvelo ebucayi.
Ngaphezu kwalokho, isidingo sokudla kwezilwane sibangela ukugawulwa kwamahlathi. Njengoba amahlathi egawulwa ukuze kuvuleleke izitshalo ezinjengobhontshisi wommbila, zonke izimiso zemvelo ziyashabalala, futhi izinhlobonhlobo zezinto eziphilayo ezake zachuma lapho zilahleka ngendlela engenakulungiseka.
Ukugawulwa kwamahlathi akubangeli nje ukushintsha kwesimo sezulu ngokukhipha isikhutha esigciniwe, kodwa kuholela nasekucekeleni phansi kwenhlabathi, ukwanda kokuguguleka kwenhlabathi, nokuncipha kwamandla okugcina amanzi .
Kubalulekile ukubhekana nale miphumela yemvelo futhi kugqugquzelwe izinqubo ezisimeme zokusetshenziswa komhlaba ezibeka eqhulwini ukongiwa kwezinhlobonhlobo zezinto eziphilayo kanye nokubuyiselwa kwe-ecosystem.
Ezinye izindlela Zokukhetha Okusimeme
Manje njengoba sesihlole imithelela yemvelo yokusetshenziswa kwenyama nobisi, ake sigxile kwezinye izindlela ezisimeme ezingasiza ekwehliseni lezi zinkinga.
