Isingeniso:
Sawubona, abathanda amabhega! Cabanga ngalokhu: ucwilisa amazinyo akho esibhega sikashizi esiphundu, esiphundu, ujabulela ukunambitheka kwayo okumnandi. Kodwa ingabe uke wema kancane ucabanga ngemiphumela ebanzi yezemvelo ecashe ngemuva kwalokho kunambitheka okumnandi? Kulo mbhalo webhulogi, sembula izindleko ezifihliwe ze-cheeseburger yakho - sihlola umthelela omkhulu ukulima kwezilwane, okuyimbangela yokukhiqizwa kwama-burger, enawo emhlabeni wethu.
I-Carbon Footprint of Animal Agriculture
Ake siqale ngokuhlola i-carbon footprint yezolimo zezilwane, okubandakanya ukukhuliswa nokuzalaniswa kwemfuyo yenyama nemikhiqizo yobisi.
I-Methane Emissions evela Emfuyweni
Wake wezwa ngalawo ma-methane cow farts adume kabi? Hhayi-ke, zingokoqobo, futhi zinomthelela ekuguqukeni kwesimo sezulu. Izinkomo nezinye izilwane ezondlayo zikhulula i-methane ngezinqubo zazo zokugaya ukudla, zibe negalelo elikhulu ekukhiqizweni kwesisi esibamba ukushisa.
Umthelela walokhu kukhishwa kwe-methane ekuguquguqukeni kwesimo sezulu akuwona umdlalo. I-methane inamandla okufudumala angaphezu kwe-carbon dioxide, nakuba ishabalalisa ngokushesha. Noma kunjalo, umphumela onqwabelene we-methane ekhiqizwa imfuyo awunakuphikwa futhi kufanele uthathwe ngokungathi sína.
Izibalo ziveza izinga elishaqisayo lalokhu kukhishwa kwegesi: ukulima kwezilwane kulinganiselwa ku-14-18% wengqikithi yesisi esikhishwa abantu emhlabeni jikelele. Lokho kuyisiqephu esikhulu!
Ukugawulwa Kwamahlathi Kwemfuyo Yemfuyo kanye Nokukhiqiza Ukudla
Wake wazibuza ukuthi ungakanani umhlaba odingekayo ezilwaneni eziningi embonini yemfuyo? Ziqinise – yinani elimangalisayo.
Ukudlelwa kwemfuyo kanye nokukhiqizwa kokudla kube yizisusa eziyinhloko zokugawulwa kwamahlathi emhlabeni jikelele. Izingxenye ezinkulu zomhlaba ziyagezwa ukuze kuhlale imfuyo, okuholela ekukhishweni okukhulu kwe-carbon dioxide. Ukwengeza, ukulahlekelwa kwezihlahla kwandisa ukuguquka kwesimo sezulu njengoba amahlathi esebenza njengamasinki e-carbon emvelo.
Bheka izindawo ezithile ezifana ne-Amazon Rainforest, lapho udedangendlale womhlaba ubhujiswe khona ukuze kufuywe izinkomo. Lokhu kucekelwa phansi akugcini nje ngokucekela phansi imvelo eyigugu kodwa futhi kukhiphela inqwaba yekhabhoni egciniwe emkhathini.
Ukungcoliswa kwamanzi kanye Nendlala
Ukulima kwezilwane kushiya okungaphezu nje kwe-carbon footprint - kuphinde kulolonge imithombo yamanzi nokutholakala ngezindlela ezishaqisayo.
Imfucuza Yezilwane Nokungcoliswa Amanzi
Ake sikhulume ngendle – ikakhulukazi, imfucuza yezilwane. Umthamo omningi okhiqizwa imfuyo uyingozi enkulu emithonjeni yethu yamanzi.
Uma ingalawulwa ngendlela efanele, imfucumfucu yezilwane ingangcolisa imifula, amachibi, namanzi angaphansi komhlaba, okubangele ukungcola okuyingozi. Lokhu kungcola kwehlisa izinga lomoya-mpilo emanzini, kubulale izilwane zasemanzini futhi kudale “izindawo ezifile.” Ngaphezu kwalokho, umsoco owedlulele emfucumfucwini wezilwane uholela eutrophication, okuthuthukisa ukukhula kwama-algal ngokweqile okulimaza imvelo.
Ukusetshenziswa Kwamanzi Ngokweqile Kwezolimo Zezilwane
Amanzi, insiza yethu ebaluleke kakhulu, anenani elilinganiselwe. Ngeshwa, ukulima kwezilwane kudla amanzi amaningi , okwenza kube nzima kakhulu emithonjeni yamanzi ecindezelwe kakade.
Cabanga ngalokhu - kuthatha amalitha amanzi alinganiselwa ku-1,800 kuya ku-2,500 ukukhiqiza ikhilogremu elilodwa nje lenyama yenkomo. Uma kuqhathaniswa nezinye izimboni, ukulima kwezilwane kuyimbangela enkulu ekusetshenzisweni ngokweqile kwensiza yethu eyigugu kakhulu.
Lokhu kusetshenziswa kwamanzi okulimazayo kuhlangana nenkinga yokushoda kwamanzi emhlabeni, okwenza kube semqoka ukuthi siphinde sihlole izinto eziza kuqala kithi futhi sithole izindlela ezisimeme zokuhlangabezana nezidingo zethu zokudla ngaphandle kokwengeza ubunzima.
Ukulahleka Kwezinto Ezihlukahlukene kanye Nokucekelwa phansi Kwendawo yokuhlala
Umthelela wemvelo wokulima kwezilwane udlulela ngale kwekhabhoni namanzi - kunomthelela ezinhlobonhlobo zemvelo nezindawo zokuhlala zeplanethi yethu.
Usongo ku-Fragile Ecosystems
Ukulima kwezilwane kunomthelela ngqo ekulahlekeni kwezindawo zokuhlala kanye nokucekelwa phansi. Amahlathi asetshenziswa ngogandaganda ukuze kuvuleke indawo yemfuyo eyengeziwe, okuthinta imvelo entekenteke futhi kuxoshwe inqwaba yezilwane.
Ukuguqulwa komhlaba wokulima kwezilwane kuyinkinga ikakhulukazi ezindaweni ezithandwa kakhulu ezinhlobonhlobo zezilwane nezindawo ezinezilwane ezisengozini yokushabalala, okuziqhubekisela phambili onqenqemeni lokushabalala.
Ukucekelwa phansi Kwenhlabathi kanye Nokulahlekelwa Umhlaba Olimekayo
Nakuba ukulima kwezilwane kunciphisa izinhlobonhlobo zezinto eziphilayo ngaphezu komhlaba, kulimaza nenhlabathi engaphansi kwezinyawo zethu.
Izindlela zokulima ezisimeme zihlose ukulondoloza impilo yomhlabathi nokuvunda; Nokho, ezinhlelweni eziningi zokulima kwezilwane , akunjalo. Ukudlisa ngokweqile kanye nokuphathwa kabi komquba kunomthelela ekugugulekeni kwenhlabathi, kucekele phansi inhlabathi engaphezulu kanye nokunciphisa amandla awo okusekela ukukhula kwezitshalo.
Lokhu kucekelwa phansi komhlaba kudala ubungozi besikhathi eside ekuvikelekeni kokudla kanye nokusimama kwezolimo, kudala umjikelezo ononya wokuncipha kwezinsiza.
Isiphetho
Njengoba siphetha uhambo lwethu oluya ezindlekweni ezifihlekile zemvelo ze-cheeseburger yakho oyithandayo, kubalulekile ukukhumbula umthelela ojulile wezolimo wezilwane emhlabeni wethu. I-carbon footprint, ukungcoliswa kwamanzi kanye nokushoda, ukulahleka kwezinhlobonhlobo zezinto eziphilayo, kanye nokucekelwa phansi kwendawo yonke kuyimiphumela edinga ukunakwa ngokushesha.
Nakuba ukukhetha komuntu siqu ekudleni kungase kubonakale kungabalulekile ohlelweni olukhulu lwezinto, zonke izinyathelo ezincane zibalulekile. Ngokwenza izinqumo ezinolwazi, ukusekela ezinye izindlela ezisimeme, kanye nokumela izinguquko, singaphokophela ekuqondeni ngendlela evumelana nemvelo.
Ngakho-ke, ngokuzayo lapho uluma i-cheeseburger ephuza emlonyeni, khumbula uhambo eyaluthatha - ukusuka emadlelweni uya emhlabeni - futhi uvumele lolo lwazi likukhuthaze ukuthi wenze umehluko.
