Okungaphezu kwalokho ukuthi i-1/3 yazo zonke izinsalela ezikhiqizwa e-United States iya ekulimeni kwezilwane. Ngokwenhlolovo e-American Journal of Clinical Nutrition (1), ukukhiqizwa kwekhalori eyodwa yeprotheyini yezilwane kudinga okungaphezu kweshumi ukufakelwa kwezinto ezindala njenge-calorie yeprotheni yezitshalo. Lokhu kusho ukuthi izikhathi eziyishumi inani le-carbon dioxide likhishwa futhi. Lonke lokhu kudoti kwenzeka kuphi?
Isilwane ngasinye esihlatshelwe ukudla kumele sondliwe ngamabele, soy, nezinye izitshalo. Ukukhiqizwa kwalezi zitshalo kudinga ukusetshenziswa kwamandla. Lokhu okuphakelayo kumelwe kuvunwe, kuhanjiswe ku-feedlots. Kulezi zilwane ezifuywayo, izilwane ziyathunyelwa endaweni yokuxoshwa, izidumbu zivame ukuhamba ngeloli (ngamaloli aseziqandisini - omunye umthengi wamandla) kuze kube esinye isitshalo sokucubungula ngaphambi kokuba inyama ilungele ukuthunyelwa esitolo. Ngesikhathi esilandelayo lapho ushayela i-interstate, ubuke wonke amaloli okuzungezile futhi ucabange ngakho konke ukukhishwa nokusetshenziswa kwebheyili ngayinye kulawo malori esebenzisa ukuhambisa izinto ezivela endaweni eyodwa kuya kwenye. Eziningi zala makili zihambisa ukudla izilwane, noma izilwane ngokwazo.
Umbiko ku-New Scientist walinganisa ukuthi ukushayela imoto ye-hybrid esikhundleni sokuthi imoto ejwayelekile ingalondoloza ithani elingaphezu kweyodwa le-carbon dioxide ngonyaka.
Ukudla okunama-vegan, noma kunjalo, kudla amathani ayisigamu nesigamu ngaphansi kwesilinganiso sokudla saseMelika (2). Ukwamukela ukudla kwe-vegan empeleni kwenza okungaphezulu ukunciphisa ukukhishwa kunokushayela imoto ye-hybrid! Ngamandla okudingeka akhiqize i-hamburger eyodwa, ungadlulisa imoto encane ngamamayela angamashumi amabili. Ngokuzayo uma ufisa umqashi, cabanga ngomgwaqo omkhulu ongayithatha!
