Pali chikhulupiliro chodziwika kuti pogula galimoto yosamalira zachilengedwe, tikupulumutsa dziko lapansi ku tsoka lachilengedwe. Pali choonadi mu izi. Koma gawo lokha. Zachilengedwe zakuthambo zikuwopsezedwa osati ndi magalimoto okha, komanso ... chakudya wamba. Ndi anthu ochepa omwe amadziwa kuti chaka chilichonse makampani azakudya aku US amatulutsa pafupifupi matani 2,8 a carbon dioxide panthawi yopanga, kupatsa mabanja ambiri aku America chakudya chachikhalidwe. Ndipo izi ngakhale kuti maulendo a galimoto ku banja lomwelo amatulutsa matani 2 a mpweya womwewo. Choncho, ngakhale pazochitika zenizeni, pali njira yofulumira komanso yotsika mtengo yothandizira kupulumutsa chilengedwe - kusinthana ndi zakudya zomwe zimakhala ndi carbon.
Zaulimi padziko lonse lapansi zimatulutsa pafupifupi 30% ya carbon dioxide yonse. Iwo amapanga greenhouse effect. Izi ndizambiri kuposa magalimoto onse. Chifukwa chake pankhani ya momwe mungachepetsere mpweya wanu masiku ano, ndibwino kunena kuti zomwe mumadya ndizofunikira monga momwe mumayendetsa. Palinso mfundo ina yofunika yomwe imakonda "zakudya" zokhala ndi mpweya wochepa: masamba ndi abwino kwa ife. Paokha, zakudya zomwe zimasiya "carbon footprint" yayikulu (nyama yofiira, nkhumba, mkaka, zokhwasula-khwasula zopangidwa ndi mankhwala) zimadzaza ndi mafuta ndi zopatsa mphamvu. Ngakhale zakudya "zobiriwira" ziyenera kukhala ndi masamba, zipatso, ndi mbewu zonse.
Kupanga chakudya kwa McDonald's kumatulutsa mpweya wambiri kuposa, monga tanenera, kuyendetsa galimoto kunja kwa tawuni. Komabe, kuti muzindikire kukula kwake, muyenera kumvetsetsa momwe msika wapadziko lonse wazakudya ulili waukulu komanso wopatsa mphamvu. Zoposa 37% za dziko lonse lapansi zimagwiritsidwa ntchito paulimi, ambiri mwa maderawa anali nkhalango. Kudula mitengo kumabweretsa kuwonjezeka kwa mpweya wa carbon. Feteleza ndi makina amasiyanso gawo lalikulu la mpweya, monganso magalimoto apanyanja omwe amapereka zakudya patebulo lanu. Pamafunika pafupifupi 7-10 mphamvu yamafuta ochulukirapo kuti apange ndikupereka chakudya kuposa momwe timapeza tikamadya chakudyacho.
Njira yothandiza kwambiri yochepetsera kuchuluka kwa kaboni pa menyu ndikudya nyama yocheperako, makamaka ng'ombe. Kuweta ziweto kumafuna mphamvu zambiri kuposa kulima mbewu monga chimanga, zipatso kapena ndiwo zamasamba. Pa calorie iliyonse yamphamvu yomwe ili muzakudya zotere, ma calories 2 amafuta amafuta amafunikira. Pankhani ya ng'ombe, chiŵerengerocho chikhoza kufika 80 mpaka 1. Komanso, ziweto zambiri ku United States zimadyetsedwa ndi tirigu wambiri - matani 670 miliyoni mu 2002. Ndipo feteleza ankalima ng'ombe, chifukwa Mwachitsanzo, pangani zovuta zina za chilengedwe, kuphatikizapo kusefukira kwa madzi komwe kumatsogolera ku malo akufa m'madzi a m'mphepete mwa nyanja, monga ku Gulf of Mexico. Ziweto zoweta pambewu zimatulutsa methane, mpweya wowonjezera kutentha umene uli wamphamvu kuŵirikiza ka 20 kuposa mpweya woipa.
Mu 2005, kafukufuku wina wa pa yunivesite ya Chicago anapeza kuti munthu mmodzi akasiya kudya nyama n’kuyamba kudya zamasamba, akhoza kusunga mpweya wofanana ndi umenewo ngati asinthana ndi Toyota Camry n’kugula Toyota Prius. Zikuwonekeratu kuti kuchepetsa kuchuluka kwa nyama yofiira yomwe imadyedwa (ndipo Achimereka amadya zoposa 27 kg ya ng'ombe pachaka) amakhalanso ndi zotsatira zabwino pa thanzi. Akatswiri amayerekezera kuti m'malo mwa magalamu 100 a ng'ombe, dzira limodzi, magalamu 30 a tchizi tsiku lililonse ndi zipatso, ndiwo zamasamba ndi mbewu zomwe zingachepetse kuyamwa kwamafuta ndikuwonjezera kudya kwa fiber. Pa nthawi yomweyi, mahekitala 0,7 a malo olima adzapulumutsidwa, ndipo kuchuluka kwa zinyalala za nyama kudzachepetsedwa kukhala matani asanu.
Ndikofunika kumvetsetsa: zomwe mumadya sizikutanthauza zochepa kuposa kumene chakudyachi chimachokera. Chakudya chathu chimayenda pafupifupi 2500 mpaka 3000 km kuchokera pamtunda kupita ku supermarket, koma ulendowu umatenga 4% yokha ya carbon footprint. Keith Gigan, katswiri wa kadyedwe komanso mlembi wa bukhu limene posachedwapa lifalitsidwe lakuti Eat Healthy and Lose Weight, Keith Gigan, anati: “Idyani zakudya zosavuta zimene mumagwiritsa ntchito popanga zinthu zochepa, muzidya ndiwo zamasamba ndi zipatso zambiri, komanso muzidya zakudya zokhala ndi nyama komanso mkaka. "Ndizosavuta."
Kuyika ma solar panels kapena kugula haibridi kungakhale komwe sitingathe kufikako, koma titha kusintha zomwe zimalowa m'matupi athu lero - ndi zosankha ngati izi zimakhudza thanzi la dziko lathu lapansi komanso ifeyo.
