Kungani inyama inomthelela omkhulu kangaka esimweni sezulu?
Cabanga ngalokhu: ngokuvamile kuphumelela kakhulu ukutshalela abantu izitshalo kunokulima izitshalo bese uphendula lezo zilwane zibe ukudla kwabantu. Abacwaningi beNhlangano Yezokudla Nezolimo yeZizwe Ezihlangene baphetha ngokuthi ngokwesilinganiso kuthatha amagremu angaba ngu-1400 okusanhlamvu ukuze kutshalwe amagremu angu-500 enyama.
Yiqiniso, abanye bangase bathi izinkomo, izinkukhu nezingulube ngokuvamile zidla izinto abantu ababengeke bazidle, njengamakhambi noma imfucumfucu yezitshalo. Yiqiniso lokhu. Kodwa ngokuvamile, kudinga umhlabathi, amandla, namanzi engeziwe ukuze kukhiqizwe amagremu angu-500 eprotheni yezilwane kunokukhiqiza amagremu angu-500 eprotheni yemifino.
Inyama yenkomo newundlu inesimo sezulu esikhulu kakhulu ngesinye isizathu: izinkomo nezimvu zinamagciwane eziswini azo azisiza ekugayeni utshani nokunye ukudla. Kodwa lawa mabhaktheriya akha i-methane, igesi enamandla ebamba ukushisa, bese idedelwa ngokubhodla (kanye ne-flatulence).
Ingabe kunendaba ukuthi izinkomo zikhuliswa kanjani?
Yebo. Ngokwesibonelo, eBolivia naseBrazil, abathengisi abakhulu kunabo bonke emhlabeni benyama yenkomo, izigidi zamahektare amahlathi emvula ziye zashiswa ukuze kwenziwe ukukhiqizwa kwenyama. Ngaphezu kwalokho, i-carbon footprint yomhlambi wezinkomo ingahluka kakhulu kuye ngezici ezifana nezimo zezulu zendawo kanye namazinga azo.
Kodwa kuthiwani uma uphakela izinkomo ngotshani futhi ungazilimeli ngokukhethekile?
Izinkomo ezifunzwa utshani zichitha isikhathi esiningi epulazini, zikhiqiza i-methane eyengeziwe.
Ingabe abantu kufanele bayeke ukudla inyama ukuze basize isimo sezulu?
Uma sifuna ukondla inani labantu elandayo ngaphandle kokusebenzisa ukufudumala kwembulunga yonke noma ukufaka ingcindezi eyengeziwe emahlathini omhlaba, kuzoba nendaba uma abadla inyama eqine kakhulu belinganisela ukudla kwabo.
Kuthiwani ngenyama yamangqamuzana okwenziwa?
Ngempela, kunezinye izinto ezithatha indawo yenyama emhlabeni. Yenziwe ngemifino, isitashi, amafutha kanye namaprotheni ahlanganisiwe, le mikhiqizo ilingisa ukunambitheka nokuthungwa kwenyama eduze kakhulu kunezinye ezithatha indawo zendabuko ezifana ne-tofu ne-seitan.
Nakuba kungakabi bikho isinqumo sokuthi lokhu kudla kunempilo yini, kubonakala kunomkhondo wemvelo omncane: olunye ucwaningo lwakamuva luthole ukuthi i-Beyond Burger ibe nengxenye eyodwa kweshumi yomthelela wesimo sezulu uma iqhathaniswa nebhega yenkomo.
Esikhathini esizayo, abacwaningi bazokwazi "ukukhulisa" inyama yangempela evela emasikweni eseli yezilwane - umsebenzi kule ndlela uyaqhubeka. Kodwa kusesekuseni kakhulu ukusho ukuthi lokhu kuzohambisana kanjani nesimo sezulu, hhayi okungenani ngoba kungase kuthathe amandla amaningi ukukhiqiza inyama ekhuliswe ngamaseli.
Kuthiwani ngokudla kwasolwandle?
Yebo, inhlanzi inekhabhoni ephansi kuneyenkukhu noma yengulube. Okuphansi kakhulu ku-shellfish, izimbaza nama-scallops. Kodwa-ke, umthombo oyinhloko nobalulekile wokukhishwa kwegesi uphethiloli oshiswa izikebhe zokudoba.
Ubisi noshizi kunamuphi umthelela ekuguqukeni kwesimo sezulu?
Ucwaningo oluningi luye lwabonisa ukuthi ubisi ngokuvamile lunesimo sezulu esincane kunenkukhu, amaqanda, noma ingulube. I-yoghurt, i-cottage shizi kanye noshizi wekhilimu kusondelene ngobisi.
Kodwa ezinye izinhlobo eziningi zikashizi, njenge-cheddar noma i-mozzarella, zingaba nendawo enkulu kakhulu kuneyenkukhu noma yengulube, njengoba ngokuvamile kuthatha cishe amakhilogremu angu-10 obisi ukukhiqiza ikhilogremu elilodwa likashizi.
Ima, ushizi mubi kunenkukhu?
Kuncike kushizi. Kodwa ngokuvamile, yebo, uma ukhetha ukudla imifino ngokuthi, yithi, udla ushizi kunenkukhu, i-carbon footprint yakho ingase ingehli ngendlela obulindele ngayo.
Ingabe ubisi lwemvelo lungcono?
E-United States, leli lebula “eliphilayo” obisini lisho ukuthi izinkomo ezichithe okungenani u-30% wesikhathi sazo ziklabile, zingatholi amahomoni noma ama-antibiotics, futhi zidle ukudla okukhuliswe ngaphandle komanyolo owenziwe noma izibulala-zinambuzane. Kuyakhanga ngempela empilweni yabantu abaningi. Kodwa asikho isidingo sokuthi ipulazi lobisi eliphilayo libe nesimo sezulu esiphansi kunepulazi elivamile. Inkinga iwukuthi, akukho okukulebula yemvelo ekutshela ngokuqondile ngomthelela wesimo sezulu walolu bisi.
Iluphi ubisi olusekelwe esitshalweni olungcono kakhulu?
Ubisi lwe-alimondi, i-oat kanye nobisi lwesoya lunokukhishwa kwegesi ebamba ukushisa ephansi kunobisi lwenkomo. Kodwa, njengenjwayelo, kukhona ukwehla kanye nokuhwebelana okufanele kucatshangelwe. Ngokwesibonelo, ama-alimondi adinga amanzi amaningi ukuze akhule. Uma unentshisekelo olwazini olwengeziwe, ungaluthola kolwethu.
