Masiku ano, dziko lapansi lili ndi zovuta zachilengedwe - ndipo ndizovuta kukhala ndi chiyembekezo pa izi. Madzi ndi nkhalango zikugwiritsiridwa ntchito mwankhanza ndipo chaka chilichonse kuchulukirachulukira, mpweya wowonjezera kutentha ukukula, mitundu yosowa ya nyama ikupitilira kutha padziko lapansi. M’maiko ambiri osauka, anthu alibe chakudya ndipo pafupifupi anthu 850 miliyoni ali ndi njala.
Kuthandizira kwaulimi wa ng'ombe ku vutoli ndikwambiri, ndiye chifukwa chachikulu cha zovuta zachilengedwe zomwe zimachepetsa moyo wapadziko lapansi. Mwachitsanzo, makampaniwa amatulutsa mpweya wowonjezera kutentha kuposa wina uliwonse! Polingalira kuti, malinga ndi zoneneratu za akatswiri a chikhalidwe cha anthu, podzafika 2050 chiŵerengero cha anthu padziko lonse chidzafika pa 9 biliyoni, mavuto amene alipo a kuweta ziweto adzakhala aakulu kwambiri. Ndipotu iwo ali kale. Ena amatcha kulima nyama zoyamwitsa m'zaka za zana la XXI "kwa nyama" moona mtima.
Tidzayesa kuyang'ana funso ili kuchokera ku mfundo zowuma:
Malo ambiri oyenera ulimi (pokula mbewu, masamba ndi zipatso!), Amagwiritsidwa ntchito poweta ng'ombe. Kuphatikizapo: 26% mwa maderawa ndi odyetsera ziweto zomwe zimadya msipu, ndi 33% zodyetsera ziweto zomwe sizimadyetsera udzu.
Pamafunika 1 kg ya tirigu kuti apange 16 kg ya nyama. Bajeti yazakudya yapadziko lonse lapansi imavutika kwambiri ndikugwiritsa ntchito tirigu! Poona kuti anthu 850 miliyoni padziko lapansi ali ndi njala, izi sizomveka bwino, osati kugawa bwino kwambiri kwazinthu.
Gawo laling'ono kwambiri - pafupifupi 30% - la tirigu wodyedwa m'mayiko otukuka (deta ya USA) amagwiritsidwa ntchito pa chakudya cha anthu, ndipo 70% amapita kukadyetsa "nyama". Zinthu zimenezi zikanatha kudyetsa anjala mosavuta ndi otsala pang’ono kufa ndi njala. Ndipotu, ngati anthu padziko lonse atasiya kudyetsa ziweto zawo ndi tirigu wodyedwa ndi anthu, tikhoza kudyetsa anthu ena 4 (pafupifupi kuwirikiza ka 5 chiwerengero cha anthu amene akuvutika ndi njala masiku ano)!
Madera a malo operekedwa kudyetsera ndi kudyetsera ziweto, omwe amapita kophera, akuwonjezeka chaka chilichonse. Pofuna kumasula madera atsopano, nkhalango zambiri zikuwotchedwa. Izi zimabweretsa chiwongola dzanja chochuluka pa chilengedwe, kuphatikizapo kukwera mtengo kwa mabiliyoni osawerengeka a zinyama, tizilombo, ndi zomera. Zamoyo zomwe zatsala pang'ono kutha zimavutikanso. Mwachitsanzo, ku United States, kudyetserako ziweto kumawopseza 14% ya mitundu yosowa komanso yotetezedwa ya nyama ndi 33% ya mitundu yosowa komanso yotetezedwa yamitengo ndi zomera.
Ulimi wa ng'ombe umagwiritsa ntchito madzi 70% padziko lapansi! Komanso, 13 okha mwa madziwa amapita kumalo kuthirira nyama "nyama" (zotsalazo ndi zofunika luso: kutsuka malo ndi ziweto, etc.).
Munthu yemwe amadya nyama amamwa ndi chakudya choterocho chiwerengero chachikulu cha "zala zala" zomwe zingakhale zovulaza kuchokera ku zomwe zimatchedwa "madzi enieni" - chidziwitso chochokera ku mamolekyu amadzi omwe amaledzera pa moyo wawo ndi nyama yomwe munthu wadya. Chiwerengero cha izi zomwe nthawi zambiri zimakhala zoyipa mwa odya nyama zimaposa kuchuluka kwa zipsera zathanzi zochokera m'madzi abwino omwe munthu amamwa.
Kupanga 1 kg ya ng'ombe kumafuna malita 1799 a madzi; 1 kg ya nkhumba - 576 malita a madzi; 1 kg ya nkhuku - 468 malita a madzi. Koma pali madera Padziko Lapansi pomwe anthu amafunikira madzi abwino, tilibe okwanira!
Osachepera "umbombo" kupanga nyama potengera kugwiritsiridwa ntchito kwa mafuta achilengedwe, komwe vuto lalikulu lakusowa likukula padziko lapansi m'zaka makumi angapo zikubwerazi (malasha, gasi, mafuta). Zimatengera nthawi 1 mafuta ochulukirapo kuti apange 9 "nyama" kalori ya chakudya (kalori imodzi ya mapuloteni a nyama) kusiyana ndi kupanga 1 calorie ya chakudya cha zomera (mapuloteni amasamba). Zida zopangira mafuta zimagwiritsidwa ntchito mowolowa manja popanga chakudya cha "nyama". Pakunyamula nyama pambuyo pake, mafuta amafunikiranso. Izi zimapangitsa kuti mafuta azigwiritsidwa ntchito kwambiri komanso mpweya woipa kwambiri mumlengalenga (kumawonjezera "carbon miles" wa chakudya).
Nyama zowetedwa kuti zidye zimatulutsa ndowe zowirikiza 130 kuposa anthu onse padziko lapansi!
Malinga ndi kuyerekezera kwa UN, ulimi wa ng'ombe umayambitsa 15.5% ya mpweya woipa - mpweya wowonjezera kutentha - mumlengalenga. Ndipo malinga ndi, chiwerengerochi ndi chapamwamba kwambiri - pamlingo wa 51%.
Kutengera ndi zida
