Mutungamiriri weOscar-winning James Cameron, uyo achangobva kuenda vegan nekuda kwezvikonzero zvetsika, anga achitsoropodza vanochengetedza vanoramba vachidya nyama.
Muvhidhiyo yeFacebook yakatumirwa muna Gumiguru 2012, Cameron anokurudzira vanodya nyama-zvakatipoteredza kuti vachinje kune kudya-kwekudyara kana vakakoshesa nezvekuchengetedza pasi.
“Haungave nyanzvi yezvakatipoteredza, haugone kuchengetedza makungwa usina kutevera gwara. Uye nzira yeramangwana - munyika yevana vedu - haigoni kupfuudzwa pasina kuchinja kune kudya kwemiti. Achitsanangura chikonzero nei akaenda vegan, Cameron, XNUMX, akanongedza kukuvadzwa kwezvakatipoteredza kunokonzerwa nekupfuya zvipfuyo zvekudya.
“Hapana chikonzero chekudya mhuka, isarudzo yedu chete,” anodaro James. Inova sarudzo yetsika ine simba guru papasi, inoparadza zviwanikwa uye inoparadza biosphere. "
Muna 2006, Food and Agriculture Organisation yeUnited Nations yakaburitsa mushumo waiti zvikamu gumi nezvisere kubva muzana zvekubuda kwegasi rinokonzerwa nevanhu rinobva mukupfuyiwa kwemhuka. Asi chokwadi, nhamba iyi iri pedyo ne18%, maererano neshumo ra51 rakaburitswa naRobert Goodland naJeff Anhang veIFC's Environment and Social Development department.
Billionaire Bill Gates nguva pfupi yadarika akaverenga kuti zvipfuyo zvinokonzeresa 51% yekubuda gasi regreenhouse. “(Kuchinjira kukudya kwemuriwo) kwakakosha tichitarisa kukanganiswa kwezvakatipoteredza kuri kuita indasitiri yenyama nemukaka, sezvo zvipfuyo zvichiburitsa chikamu che51% chegasi regreenhouse pasi rose,” vakadaro.
Vamwe vezvemhoteredzo vanozivikanwa zvikuru vanotsigirawo kudya mirivo, vachidudza kukuvadzwa kunokonzerwa nokuchengeta mhuka. Rajendra Pachauri, sachigaro weIntergovernmental Commission on Climate Change, nguva pfupi yadarika akataura kuti chero munhu anogona kubatsira kuderedza kuburitswa kwegasi regreenhouse nekungoderedza kudyiwa kwenyama.
Panguva imwecheteyo, Nathan Pelletier, nyanzvi yezvehupfumi hwezvakatipoteredza paDalhousie University, Halifax, Nova Scotia, anoti mhou dzinopfuudzwa nokuda kwezvokudya ndiyo dambudziko guru: ndidzo dzakasimudzwa pamapurazi emafekitari.
Pelletiere anoti mombe dzakadyiswa uswa dziri nani pane mombe dziri kupurazi, dzinopomba mahomoni nemishonga inorwisa mabhakitiriya uye dzinogara munzvimbo dzisina hutsanana dzinotyisa dzisati dzaurayiwa.
“Kana chaunonyanya kunetseka nacho chiri kuderedza kuburitswa, haufanirwe kudya nyama yemombe,” anodaro Pelletier, achiona kuti pa0,5 kg yega yemombe inoburitsa 5,5-13,5 kg yecarbon dioxide.
“Kuchengetwa kwezvipfuyo kwakangofanana nekuchera migodhi. Haina kugadzikana, tinotora pasina kupa chero chinhu mukudzoka. Asi kana ukadyisa mhou huswa, equation inoshanduka. Uchapa zvinopfuura zvaunotora.”
Zvisinei, dzimwe nyanzvi dzinopokana nepfungwa yekuti mombe dzehuswa hadzina kukuvadza nharaunda kana dzichienzaniswa nedzomufekitari.
Dr. Jude Capper, mutevedzeri wapurofesa wesainzi yemukaka paWashington State University, vanoti mhou dzakadyiswa uswa dzakangoipa kune zvakatipoteredza sezvakaita dziya dzinorerwa mumapurazi emaindasitiri.
“Mhuka dzinodyiswa uswa dzinofanirwa kutamba muzuva, dzichisvetuka nokuda kwomufaro nokunakidzwa,” anodaro Capper. "Takawana kubva panyika, simba nemvura, uye carbon footprint, kuti mhou dzakadyiswa uswa dzakaipa zvikuru kupfuura mhou dzakadyiswa chibage."
Zvisinei, nyanzvi dzose dzezvinomera dzinobvumirana kuti kufudza kunotyisidzira pasi, uye kudya kwemiti kunonyanya kukoshesa zvakatipoteredza kupfuura nyama-based one. Mark Reisner, aimbova mutori wenhau wevashandi veNatural Resources Conservation Council akazvipfupikisa zvakajeka, achinyora kuti, “MuCalifornia, mutengi mukuru wemvura haasi Los Angeles. Haisi iyo mafuta, makemikari kana maindasitiri ekudzivirira. Kwete minda yemizambiringa kana mibhedha yemadomasi. Aya mafuro anodiridzwa. Dambudziko remvura rekuMadokero - uye matambudziko mazhinji ezvakatipoteredza - anogona kupfupikiswa neshoko rimwe chete: zvipfuyo. "
