Kana ukarega kudya nyama, chikafu chako chine chekuita nekabhoni chinozove nepakati. Uku kudonha kwakakura kupfuura kwaimbofungwa, uye data idzva rinobva kudhata rekudya kubva kuvanhu chaivo.
Chikamu chechina chakazara chemagetsi edu egreenhouse gasi anobva mukugadzirwa kwechikafu. Nekudaro, hazvina kujeka kuti ingani vanhu vanganyatso chengetedza kana vakachinja kubva kune steak kuenda kune tofu burgers. Nekumwe fungidziro, kuenda vegan kwaizocheka izvo zvinobuda ne25%, asi zvese zvinoenderana nezvaunodya pane nyama. Mune zvimwe zviitiko, kubudiswa kunogona kutowedzera. Peter Scarborough nevamwe vaaishanda navo kuOxford University vakatora data yezvekudya chaiyo kubva kune vanhu vanopfuura 50000 muUnited Kingdom uye vakaverenga yavo yekudya kabhoni tsoka. "Iri ndiro basa rekutanga rinosimbisa uye kuverenga mutsauko," anodaro Scarborough.
Kumisa kuburitsa
Masayendisiti akawana kuti mubairo wacho unogona kuva mukuru. Kana avo vanodya 100 magiramu enyama pazuva - diki rump steak - vakave vegan, yavo kabhoni footprint yaizoderedzwa ne60%, kuderedza carbon dioxide emissions nematani 1,5 pagore.
Heino mufananidzo wakanyatsojeka: kana avo vanodya zvinopfuura magiramu zana enyama pazuva vaizocheka kudya kwavo kusvika kumagiramu makumi mashanu, tsoka yavo yaizodonha nechetatu. Izvi zvinoreva kuti inenge toni yeCO100 yaizoponeswa pagore, zvakangofanana nekirasi yehupfumi inobhururuka kubva kuLondon kuenda kuNew York. Pescatarians, vanodya hove asi vasingadyi nyama, vanopa chete 50% yakawanda kune emissions kupfuura vanodya miriwo. Vegans, kune rumwe rutivi, ndiyo inonyanya "kushanda", ichipa 2% zvishoma kune emissions kupfuura vanodya miriwo vanodya mazai uye zvigadzirwa zvemukaka.
"Pakazere, pane kudzika uye kwakasimba kuderera kwehutsi kubva pakudya nyama shoma," anodaro Scarborough.
Chii chokufunga nezvacho?
Kune dzimwe nzira dzekudzikisa kubuda, sekutyaira zvishoma uye kubhururuka, asi shanduko yekudya ichave nyore kune vakawanda, Scarborough anodaro. "Ndinofunga kuti zviri nyore kuchinja kudya kwako pane kuchinja maitiro ako ekufamba, kunyange zvazvo vamwe vangasabvumirana nazvo."
"Ichi chidzidzo chinoratidza kubatsira kwezvakatipoteredza kwekudya kwakaderera-nyama," anodaro Christopher Jones weYunivhesiti yeCalifornia kuBerkeley.
Muna 2011, Jones akafananidza nzira dzese dzeavhareji mhuri yeAmerica inogona kuderedza kuburitsa kwavo. Kunyange zvazvo chikafu chakanga chisiri chitubu chikuru chekubuda kwehutsi, munzvimbo iyi ndimo maikwanisa kuchengetedza vanhu zvakanyanya kuburikidza nekupambadza chikafu chishoma uye kudya nyama shoma. Jones akaverenga kuti kuderedza kubudiswa kweCO2 netani imwe kunochengetedza pakati pemadhora mazana matanhatu nemazana manomwe emadhora.
"Vanhu vekuAmerica vanorasa chinenge chikamu chimwe muzvitatu chezvokudya zvavanotenga uye vanodya 30% mamwe macalorie kupfuura anokurudzirwa," anodaro Jones. "Kune vanhu vekuAmerica, kutenga nekudya chikafu chidiki kunogona kuderedza mhepo inobuda kupfuura kungocheka nyama."
