Ngo-Agasti 5, 2013, usosayensi waseDashi u-Mark Post wethula i-hamburger yokuqala emhlabeni ekhuliswe elabhorethri esithangamini nabezindaba. Ama-gourmets awazange athande ukunambitheka kwenyama, kodwa i-Post yathi inhloso yale burger ukukhombisa ukuthi kungenzeka ukutshala inyama endaweni yokucwaninga, futhi ukunambitheka kungathuthukiswa ngokuhamba kwesikhathi. Kusukela ngaleso sikhathi, izinkampani ziye zaqala ukukhulisa inyama "ehlanzekile" engeyona i-vegan, kodwa abanye bakholelwa ukuthi inamandla okunciphisa kakhulu ukufuywa kwezilwane esikhathini esizayo.
Inyama ekhule elebhu iqukethe imikhiqizo yezilwane
Nakuba inani lezilwane ezisetshenziswayo lizoncishiswa, inyama yaselabhorethri isadinga amakheji ezilwane. Lapho ososayensi bedala inyama yokuqala ekhule elebhu, baqala ngamaseli emisipha yengulube, kodwa amaseli nezicubu azikwazi ukuzala ngaso sonke isikhathi. Ukukhiqizwa okuningi "kwenyama ehlanzekile" kunoma yikuphi kudinga ukuhlinzekwa kwezingulube eziphilayo, izinkomo, izinkukhu nezinye izilwane lapho amaseli angathathwa khona.
Ngaphezu kwalokho, ukuhlola kwasekuqaleni kwakuhilela ukukhula kwamangqamuzana “emhluzweni weminye imikhiqizo yezilwane,” okusho ukuthi izilwane zazisetshenziswa futhi ngokunokwenzeka zibulawe ngokuqondile ukuze kwakhiwe umhluzi. Ngakho-ke, umkhiqizo awukwazi ukubizwa ngokuthi i-vegan.
I-Telegraph kamuva yabika ukuthi amangqamuzana e-porcine stem akhuliswa kusetshenziswa i-serum ethathwe emahhashini, nakuba kungacaci ukuthi le serum iyafana yini nomhluzi womkhiqizo wezilwane osetshenziswa ekuhloleni kokuqala.
Ososayensi banethemba lokuthi inyama yelebhu izonqamula ukukhishwa kwesisi esibamba ukushisa, kodwa ukukhula kwamaseli ezilwane kumalebhu noma nini maduze kusazoba ukumosha kwezinsiza, noma ngabe amaseli etshalwe endaweni ye-vegan.
Ingabe inyama izoba yi-vegan?
Ukucabanga ukuthi amangqamuzana angafi ezinkomo, izingulube, nezinkukhu angathuthukiswa, futhi akukho zilwane ezizobulawa ukukhiqizwa kwezinhlobo ezithile zenyama, inqobo nje uma ukusetshenziswa kwezilwane ekuthuthukiseni inyama yaselabhorethri kuqhubeka. Ngisho nanamuhla, ngemva kwezinkulungwane zeminyaka yokufuywa kwezilwane ngendlela evamile, ososayensi basazama ukuthuthukisa izinhlobo ezintsha zezilwane ezizokhula zibe zinkulu futhi ngokushesha, ezinyama yazo eyoba nezinzuzo ezithile futhi imelane nezifo. Esikhathini esizayo, uma inyama yaselabhorethri iba umkhiqizo okwazi ukuhwebelana, ososayensi bazoqhubeka nokuzalanisa izinhlobo ezintsha zezilwane. Okusho ukuthi, bazoqhubeka nokuhlola amaseli ezinhlobo ezahlukene nezinhlobo zezilwane.
Ngokuzayo, inyama ekhuliswe elebhu kungenzeka inciphise ukuhlupheka kwezilwane. Kodwa kubalulekile ukukhumbula ukuthi ngeke kube yimifino, kancane kancane i-vegan, nakuba ingewona umkhiqizo wonya olukhona embonini yokufuywa kwezilwane. Ngandlela thize, izilwane zizohlupheka.

“Uma ngikhuluma ‘ngenyama ehlanzekile’, abantu abaningi bangitshela ukuthi iyanengeka futhi iphambene nemvelo.” Abanye abantu abaqondi nje ukuthi umuntu angawudla kanjani? Abakuqapheli abaningi ukuthi u-95% wayo yonke inyama edliwa emazweni aseNtshonalanga ivela emapulazini emboni, futhi akukho okuza ngokwemvelo emapulazini emboni. Lutho.
Lezi izindawo lapho izinkulungwane zezilwane ezizwelayo zithuthelwa ezikhala ezincane izinyanga futhi zime endle nasemchamweni wazo. Angase agcwale izidakamizwa nama-antibiotics, iphupho elibi ongeke ulifise nakusona isitha sakho esikhulu. Abanye abakuboni ukukhanya noma baphefumule umoya omusha impilo yabo yonke kuze kufike usuku abayiswa ngalo esilaheni babulawe.
Ngakho-ke, uma ubheka ukwesabeka okuhlelekile kwesakhiwo sezimboni zezolimo, ingabe ama-vegans kufanele asekele inyama ehlanzekile, noma ingeyona i-vegan ngoba yenziwe ngamaseli ezilwane?
Umbhali we-Clean Meat u-Paul Shapiro wangitshela, “Inyama ehlanzekile ayenzelwanga inyama yezilwane—yinyama yangempela. Kepha ama-vegans kufanele asekele ukusungulwa kwenyama ehlanzekile njengoba ingasiza izilwane, iplanethi nempilo yomphakathi - izizathu ezintathu eziphezulu abantu bakhetha ukuzidla inyama. ”
Ukwakha inyama ehlanzekile kusebenzisa ingxenye yemithombo yemvelo edingekayo ukuze kukhiqizwe inyama.
Ngakho yikuphi okungokwemvelo? Ukuhlukumeza nokuhlukumeza izilwane ngenxa yenyama yazo kuyilapho ngasikhathi sinye kucekela phansi iplanethi yethu? Noma ukukhulisa izicubu ezindaweni zokucwaninga ezihlanzekile nezihlanzekile ngaphandle kokuhlaba izinkulungwane zezigidi zezinto eziphilayo ngezindleko eziphansi endaweni ezungezile?
Ekhuluma ngokuphepha kwenyama ehlanzekile, uShapiro uthi: “Inyama ehlanzekile cishe izovikeleka futhi ilondolozeke kangcono kunenyama evamile namuhla. Kubalulekile ukuthi abantu besithathu abathembekile (hhayi nje abakhiqizi ngokwabo) njengokuphepha kokudla, inhlalakahle yezilwane kanye namaqembu emvelo basize ukufundisa abathengi mayelana nezinzuzo ezihlinzekwa ukusungulwa kwenyama ehlanzekile. Ngokwesilinganiso, inyama ehlanzekile ngeke ikhiqizwe ezindaweni zokucwaninga, kodwa ezimbonini namuhla ezifana nezindawo zokuphisa utshwala.”
Ikusasa leli. Futhi njengobunye ubuchwepheshe obuningi obabukhona ngaphambili, abantu babesaba, kodwa base beqala ukusetshenziswa kabanzi. Lobu buchwepheshe bungasiza ukuqeda ukufuywa unomphela.”
Sonke siyaqonda ukuthi uma umkhiqizo usebenzisa isilwane, awufanelekile kuma-vegans. Kodwa uma inani labantu emhlabeni liqhubeka futhi lizoqhubeka lidla inyama, mhlawumbe “inyama ehlanzekile” isazosiza ekusindiseni izilwane nendawo ezungezile?
