Kunenkolelo edumile yokuthi ngokuthenga imoto ehambisana nemvelo, sisindisa umhlaba enhlekeleleni yemvelo. Kukhona iqiniso kulokhu. Kodwa isabelo kuphela. I-ecology yamaplanethi asongelwa hhayi ngezimoto kuphela, kodwa futhi ... nokudla okuvamile. Bambalwa abantu abazi ukuthi minyaka yonke imboni yokudla yase-US ikhipha amathani angaba ngu-2,8 esikhutha ngesikhathi sokukhiqiza, ihlinzeka umndeni ojwayelekile waseMelika ngokudla kwendabuko. Futhi lokhu naphezu kweqiniso lokuthi uhambo ngemoto emndenini ofanayo lukhipha amathani angu-2 wegesi efanayo. Ngakho-ke, ngisho nangombono ongokoqobo, kukhona inketho esheshayo futhi eshibhile yokufaka isandla ekusindiseni imvelo - ukushintshela ekudleni okunokuqukethwe okuncane kwekhabhoni.
Inkimbinkimbi yezolimo yomhlaba ikhipha cishe ama-30% ayo yonke i-carbon dioxide. Bakha umphumela we-greenhouse. Lokhu kungaphezulu kakhulu kwalokho okuphuma kuzo zonke izimoto. Ngakho-ke uma kuziwa endleleni yokunciphisa i-carbon footprint yakho namuhla, kuphephile ukusho ukuthi okudlayo kubaluleke kakhulu njengoba ushayela. Kukhona elinye iqiniso elibalulekile elivuna "ukudla" kwekhabhoni ephansi: imifino ilungele thina. Ngokwazo, ukudla okushiya "i-carbon footprint" enkulu (inyama ebomvu, ingulube, imikhiqizo yobisi, ukudla okulula okwenziwe ngamakhemikhali) kugcwele amafutha nama-calories. Nakuba ukudla "okuluhlaza" kufanele kufake imifino, izithelo, nokusanhlamvu okuphelele.
Ukukhiqizwa kokudla kwe-McDonald's kukhipha i-carbon eningi, njengoba sesishilo, ukushayela imoto ngaphandle kwedolobha. Kodwa-ke, ukuze ubonge izinga, udinga ukuqonda ukuthi inkulu kangakanani futhi idinga amandla kangakanani imboni yokudla yomhlaba wonke. Ngaphezu kwama-37% omhlaba wonke weplanethi usetshenziselwa ukulima, iningi lale ndawo bekungamahlathi. Ukugawulwa kwamahlathi kuholela ekwandeni kokuqukethwe kwekhabhoni. Izivundisi nemishini nakho kushiya i-carbon footprint ebalulekile, njengezimoto ezihamba olwandle eziletha igrosa ngqo etafuleni lakho. Kudingeka ngokwesilinganiso izikhathi ezingu-7-10 amandla kaphethiloli amaningi ukukhiqiza nokuletha ukudla kunaleyo esiyithola ngokudla lokho kudla.
Indlela ephumelela kakhulu yokunciphisa i-carbon footprint yemenyu yakho ukudla inyama encane, ikakhulukazi inyama yenkomo. Ukukhulisa imfuyo kudinga amandla amaningi kunokulima okusanhlamvu, izithelo noma imifino. Kuwo wonke amakhalori wamandla aqukethwe ekudleni okunjalo, amakhalori angu-2 wamandla kaphethiloli ayadingeka. Endabeni yenkomo, isilinganiso singafinyelela ku-80 kuya ku-1. Ngaphezu kwalokho, imfuyo eningi e-United States ifuywa ngenani elikhulu lokusanhlamvu - amathani ayizigidi ezingu-670 ngo-2002. Futhi umanyolo wawusetshenziselwa ukutshala inyama yenkomo, isibonelo, ukudala izinkinga ezengeziwe zemvelo, kuhlanganise nokugeleza okuholela ezindaweni ezifile emanzini asogwini, njengaseGulf of Mexico. Imfuyo efuywa ngokusanhlamvu ikhipha i-methane, igesi ebamba ukushisa enamandla ngokuphindwe izikhathi ezingu-20 kune-carbon dioxide.
Ngo-2005, ucwaningo lwaseNyuvesi yaseChicago lwathola ukuthi uma umuntu oyedwa eyeka ukudla inyama bese eshintshela ekudleni kwemifino, angakwazi ukonga inani elifanayo le-carbon dioxide njengokungathi ushintsha iToyota Camry ngeToyota Prius. Kuyacaca ukuthi ukunciphisa inani lenyama ebomvu edliwayo (futhi amaMelika adla ngaphezu kwe-27 kg yenkomo ngonyaka) futhi kunomphumela omuhle empilweni. Ochwepheshe balinganisela ukuthi ukushintsha amagremu angu-100 enyama yenkomo, iqanda elilodwa, amagremu angu-30 kashizi nsuku zonke ngenani elifanayo lezithelo, imifino nokusanhlamvu kunganciphisa ukumuncwa kwamafutha futhi kwandise ukudla kwefayibha. Ngesikhathi esifanayo, amahektha angu-0,7 omhlaba olimekayo azosindiswa, futhi inani lemfucumfucu yezilwane lizoncishiswa libe ngamathani ama-5.
Kubalulekile ukuqonda: okudlayo akusho okuncane kunalokho okuvela lapho lokhu kudla. Ukudla kwethu kuhamba ibanga elingamakhilomitha angama-2500 kuya kwezi-3000 ukusuka ezweni kuya esitolo esikhulu, kodwa lolu hambo luthatha kuphela u-4% wokudla okunekhabhoni. “Yidla ukudla okulula okusebenzisa izinsiza ezimbalwa ukuze ukhiqize, udle imifino nezithelo ezengeziwe, futhi unciphise inyama nemikhiqizo yobisi,” kusho uKeith Gigan, isazi sokudla okunempilo nomlobi wencwadi ezonyatheliswa maduze ethi Eat Healthy and Lose Weight. “Kulula.”
Ukufaka amaphaneli elanga noma ukuthenga ingxubevange kungase kungabi khona kithi, kodwa singashintsha lokho okungena emizimbeni yethu namuhla - futhi izinqumo ezinjengalezi zibalulekile empilweni yeplanethi yethu neyethu.
