Mazuva ano, nyika ine mamiriro ezvakatipoteredza akaoma - uye zvakaoma kuva netariro pamusoro peizvi. Zviwanikwa zvemvura nemasango zviri kushandiswa zvine utsinye uye gore negore zvinowedzera kuderedzwa, kubudiswa kwemagasi egreenhouse kuri kukura, marudzi asingawanzooneki emhuka ari kuramba achinyangarika pachiso chepasi. Munyika dzakawanda dzine urombo, vanhu havana zvokudya uye vanenge mamiriyoni 850 vanoziya nenzara.
Mupiro wekupfuya nyama yemombe kudambudziko iri wakakura, ndicho chikonzero chikuru chematambudziko mazhinji ezvakatipoteredza anoderedza mararamiro ePasi. Semuenzaniso, indasitiri iyi inoburitsa magasi egreenhouse akawanda kupfuura mamwe ese! Tichifunga kuti, maererano nekufanotaura kwenyanzvi dzemagariro evanhu, panosvika 2050 chiverengero chavagari vapasi chichasvika mabhiriyoni 9, zvinetso zviripo zvokuchengeta mhuka zvichava zvakanyanyisa. Kutaura zvazviri, vakatodaro. Vamwe vane manzwiro vanodana kurimwa kwemhuka dzinoyamwisa muzana remakore reXXI "zvenyama" pachena.
Tichaedza kutarisa mubvunzo uyu kubva pakuona kwezvakaoma chokwadi:
Yakawanda yenyika yakakodzera kurima (yekurima zviyo, miriwo uye michero!), Inoshandiswa pakuzvara mombe dzemombe. Zvinosanganisira: Chikamu che26% chenzvimbo idzi ndechemafuro ezvipfuyo zvinodya kumafuro, uye 33% yekudyisa zvipfuyo zvisingafudze huswa.
Zvinotora 1 kg yezviyo kugadzira 16 kg yenyama. Huwandu hwekudyara hwepasi rose hunotambura zvakanyanya nekushandiswa kwezviyo uku! Tichifunga nezvekuti 850 miriyoni vanhu vari pasi pano vari kufa nenzara, iyi haisi iyo yakanyanya kunaka, kwete iyo inonyanya kugovera zviwanikwa.
Chikamu chiduku zvikuru - inenge 30% chete - yezviyo zvinodyiwa munyika dzakabudirira (data yeU.SA) inoshandiswa pakudya kwevanhu, uye 70% inoenda kunodyisa "nyama" mhuka. Migove iyi yaigona kudya nyore nyore vane nzara nevanofa nenzara. Kutaura zvazviri, kana vanhu munyika yose vakarega kudyisa zvipfuwo zvavo nezviyo zvinodya vanhu, tinogona kudyisa vamwe vanhu 4 (kanenge ka5 nhamba yevanhu vari kufa nenzara nhasi)!
Nzvimbo dzevhu dzakapihwa kudyisa nemafuro ezvipfuyo, dzinozoenda kunouraira, dzinowedzera gore negore. Kuti nzvimbo itsva dzisunungurwe, masango akawanda ari kupiswa. Izvi zvinopa mutero unorema pane zvakasikwa, kusanganisira mutengo wemabhiriyoni asingaverengeki emhuka, tumbuyu, uye zvirimwa. Mhuka dziri mungozi dzinotamburawo. Semuenzaniso, muUnited States, mafuro anotyisidzira 14% yemhuka dzisingawanzo uye dzakachengetedzwa uye 33% yemhando dzisingawanzo uye dzakachengetedzwa dzemiti nemiti.
Kurima nyama yemombe kunopedza chikamu che70% chemvura yepasi rose! Uyezve, gumi nematatu chete emvura iyi inoenda kunzvimbo yekudiridza yemhuka dze "nyama" (yakasara ndeyezvinodiwa zvehunyanzvi: kugezwa kwenzvimbo uye zvipfuwo, nezvimwewo).
Munhu anodya nyama anotora nechikafu chakadaro nhamba yakawanda inogona kukuvadza "mashoko eminwe" kubva kune inonzi "virtual water" - ruzivo kubva kumamolekoro emvura akadhakwa munguva yehupenyu hwavo nemhuka yakadyiwa nemunhu. Huwandu hweaya anowanzo dhinda asina kunaka mune vanodya nyama zvakanyanya kupfuura huwandu hweane hutano anodhinda kubva mumvura yakachena iyo munhu anonwa.
Kugadzirwa kwe1 kg yemombe inoda 1799 malita emvura; 1 kg yenguruve - 576 malita emvura; 1 kg yehuku - 468 malita emvura. Asi kune matunhu paPasi apo vanhu vanoda mvura yakachena, isu hatina yakakwana!
Hapana zvishoma "makaro" kugadzirwa kwenyama maererano nekushandiswa kwemafuta echisikigo, ayo dambudziko rekushomeka kwakanyanya kuri kuitika panyika yedu mumakumi emakore anotevera (marasha, gasi, oiri). Zvinotora 1 nguva yakawanda yefossil mafuta kuti ibudise 9 "nyama" calorie yezvokudya (imwe calorie yeprotein yemhuka) pane kugadzira 1 calorie yezvokudya zvezvirimwa (vegetable protein). Fossil mafuta emafuta anoshandiswa nerupo mukugadzira chikafu che "nyama" mhuka. Nokuda kwekutakura nyama kunotevera, mafuta anodiwa zvakare. Izvi zvinotungamira kukushandiswa kwemafuta kwakanyanya uye kuburitsa kwakakosha kunokuvadza mumhepo (kunowedzera "carbon mamaira" echikafu).
Mhuka dzinochengeterwa nyama dzinobudisa tsvina yakapetwa ka130 kupfuura vanhu vose vari panyika!
Zvinoenderana nekufungidzira kweUN, kurima nyama yemombe ndiko kukonzeresa 15.5% yehutsi hunokuvadza - magasi egreenhouse - mumhepo. Uye maererano, nhamba iyi yakakwirira zvikuru - pamwero we51%.
Kubva pane zvigadzirwa
