Kodi zomwe ndimadya zimakhudza kusintha kwa nyengo?
Inde. Dongosolo la chakudya padziko lonse ndi limene limayambitsa pafupifupi gawo limodzi mwa magawo anayi a mpweya wotenthetsera dziko lapansi umene anthu amapanga chaka chilichonse. Izi zikuphatikizapo kulima ndi kukolola zomera zonse, zinyama ndi zinyama - ng'ombe, nkhuku, nsomba, mkaka, mphodza, kabichi, chimanga ndi zina. Komanso kukonza, kulongedza ndi kutumiza chakudya kumisika padziko lonse lapansi. Ngati mudya chakudya, muli mbali ya dongosolo lino.
Kodi kwenikweni chakudya chikugwirizana bwanji ndi kutentha kwa dziko?
Pali zolumikizana zambiri. Nazi zinayi mwa izo:
1. Nkhalango zikadulidwa kuti minda ndi ziweto zikhalepo (izi zimachitika tsiku ndi tsiku m’madera ena a dziko lapansi), nkhokwe zazikulu za carbon zimatulutsidwa mumlengalenga. Zimatenthetsa dziko lapansi.
2. Ng’ombe, nkhosa ndi mbuzi zikagaya chakudya, zimatulutsa methane. Ndi mpweya wina wamphamvu wowonjezera kutentha womwe umathandizira kusintha kwanyengo.
3. M'minda ya manyowa ndi kusefukira kwa madzi komwe amagwiritsidwa ntchito polima mpunga ndi mbewu zina ndiwonso magwero amphamvu a methane.
4. Mafuta amafuta amagwiritsidwa ntchito kuyendetsa makina aulimi, kupanga feteleza ndikupereka chakudya padziko lonse lapansi, chomwe chimawotchedwa ndikutulutsa mpweya mumlengalenga.
Ndi zinthu ziti zomwe zimakhudza kwambiri?
Nyama ndi mkaka, makamaka kuchokera ku ng'ombe, zimakhudza kwambiri. Ziweto zimapanga pafupifupi 14,5% ya mpweya wowonjezera kutentha padziko lonse lapansi chaka chilichonse. Izi ndizofanana ndi magalimoto onse, magalimoto, ndege ndi zombo zonse pamodzi.
Ponseponse, ng'ombe ndi mwanawankhosa zimakhudza kwambiri nyengo pa gramu imodzi ya mapuloteni, pomwe zakudya zamasamba sizimakhudza kwambiri. Nkhumba ndi nkhuku zili pakati. Kafukufuku yemwe adasindikizidwa chaka chatha m'magazini ya Science adapeza kuti mpweya wowonjezera kutentha umatulutsa (mu ma kilogalamu a CO2) pa magalamu 50 a mapuloteni:
Ng'ombe ya Ng'ombe 17,7 Mwanawankhosa 9,9 imodzi
Izi ndi ziwerengero zapakati. Ng'ombe yoweta ku United States nthawi zambiri imatulutsa mpweya wocheperako kuposa ng'ombe ya ku Brazil kapena ku Argentina. Tchizi zina zimatha kukhala ndi mpweya wowonjezera kutentha kuposa kuwaza mwanawankhosa. Ndipo akatswiri ena amakhulupirira kuti ziwerengerozi zingachepetse kuyambukira kwa kulima- ndi kuwononga nkhalango kokhudzana ndi ubusa.
Koma kafukufuku wambiri amagwirizana pa chinthu chimodzi: zakudya zochokera ku zomera sizikhala ndi mphamvu zochepa kusiyana ndi nyama, ndipo ng'ombe ndi mwanawankhosa ndizowononga kwambiri mlengalenga.
Kodi pali njira yosavuta yosankhira chakudya chomwe chingachepetse kutentha kwanga?
Kudya nyama yofiira yochepa ndi mkaka kumakhala ndi zotsatira zambiri kwa anthu ambiri m'mayiko olemera. Mutha kudya zakudya zochepa zomwe zili ndi nyengo yayikulu kwambiri, monga ng'ombe, nkhosa ndi tchizi. Zakudya zochokera ku zomera monga nyemba, nyemba, mbewu, ndi soya nthawi zambiri zimakhala zokonda nyengo kuposa zonse.
Kodi kusintha zakudya zanga kungathandize bwanji dziko?
Kafukufuku wambiri wasonyeza kuti anthu omwe panopa amadya zakudya za nyama, kuphatikizapo anthu ambiri ku United States ndi ku Ulaya, akhoza kuchepetsa chakudya chawo ndi gawo limodzi mwa magawo atatu kapena kuposerapo mwa kusintha zakudya zamasamba. Kudula mkaka kumachepetsa utsiwu kwambiri. Ngati simungathe kusintha kwambiri zakudya zanu. Chitanipo kanthu pang’onopang’ono. Kungodya zochepa nyama ndi mkaka ndi zomera zambiri akhoza kale kuchepetsa mpweya.
Kumbukirani kuti kumwa chakudya nthawi zambiri ndi gawo laling'ono chabe la kuchuluka kwa mpweya wa munthu, komanso momwe mumayendetsa, kuwuluka ndi kugwiritsa ntchito mphamvu kunyumba ziyeneranso kuganiziridwa. Koma kusintha kwa zakudya nthawi zambiri ndi imodzi mwa njira zofulumira kwambiri zochepetsera kukhudzidwa kwanu padziko lapansi.
Koma ndili ndekha, ndingakhudze bwanji china chake?
Izi ndi Zow. Munthu mmodzi angachite zochepa pothandiza vuto la nyengo padziko lonse. Ili ndi vuto lalikulu lomwe likufunika kuchitapo kanthu komanso kusintha kwa mfundo kuti lithetsedwe. Ndipo chakudya sichimawonjezera kwenikweni kutentha kwa dziko - zambiri zimayamba chifukwa cha kuyaka kwamafuta opangira magetsi, zoyendera, ndi mafakitale. Kumbali ina, ngati anthu ambiri pamodzi asintha zakudya zawo za tsiku ndi tsiku, ndizo zabwino.
Asayansi akuchenjeza kuti m’zaka zikubwerazi tikuyenera kuchepetsa kukhudzidwa kwa ulimi pa nyengo ngati tikufuna kuthana ndi kutentha kwa dziko, makamaka pamene chiwerengero cha anthu padziko lonse chikukwera. Kuti zimenezi zitheke, alimi adzafunika kupeza njira zochepetsera utsi wawo ndi kukhala achangu kwambiri, kulima chakudya chochuluka m’malo ochepa kuti achepetse kuwononga nkhalango. Koma akatswiri anenanso kuti zingathandize kwambiri ngati odya nyama ochulukirachulukira padziko lonse lapansi achepetsa zilakolako zawo ngakhale pang'ono, zomwe zimathandizira kumasula nthaka kuti idyetse wina aliyense.
