Yog tias koj tsis noj nqaij, koj cov zaub mov ntsig txog cov pa roj carbon hneev taw yuav raug txo qis. Qhov no yog qhov poob loj dua li qhov kev xav yav dhau los, thiab cov ntaub ntawv tshiab los ntawm cov ntaub ntawv noj haus los ntawm cov neeg tiag tiag.
Ib tag nrho peb lub hlis twg ntawm peb lub tsev xog paj emissions yog los ntawm kev tsim khoom noj. Txawm li cas los xij, nws tsis paub meej npaum li cas tib neeg yuav txuag tau yog tias lawv hloov los ntawm steaks rau tofu burgers. Los ntawm qee qhov kev kwv yees, mus vegan yuav txiav cov emissions los ntawm 25%, tab sis nws tag nrho yog nyob ntawm seb koj noj dab tsi es tsis txhob nqaij. Qee zaum, emissions tseem tuaj yeem nce ntxiv. Peter Scarborough thiab nws cov npoj yaig ntawm Oxford University tau coj cov ntaub ntawv kev noj haus hauv lub neej tiag tiag los ntawm ntau dua 50000 tus neeg hauv tebchaws United Kingdom thiab suav lawv cov pa roj carbon monoxide. Scarborough hais tias "Qhov no yog thawj txoj haujlwm uas lees paub thiab suav qhov sib txawv,"
Nres emissions
Cov kws tshawb fawb tau pom tias cov nyiaj them poob haujlwm tuaj yeem loj heev. Yog tias cov neeg uas noj 100 grams ntawm cov nqaij ib hnub - ib tug me me rump steak - ua vegan, lawv cov pa roj carbon hneev taw yuav raug txo los ntawm 60%, txo carbon dioxide emissions los ntawm 1,5 tons ib xyoo.
Ntawm no yog daim duab tiag tiag: yog tias cov neeg uas noj ntau dua 100 grams ntawm cov nqaij ib hnub twg yuav tsum txiav lawv cov khoom noj kom tsawg li 50 grams, lawv cov hneev taw yuav poob los ntawm ib feem peb. Qhov no txhais tau hais tias yuav luag ib tonne ntawm CO2 yuav tau txais kev cawmdim nyob rau ib xyoos, hais txog tib yam li ya davhlau kev lag luam los ntawm London mus rau New York. Pescatarians, uas noj ntses tab sis tsis noj nqaij, tsuas yog 2,5% ntxiv rau emissions dua li cov neeg tsis noj nqaij.

Scarborough hais tias "Zuag qhia tag nrho, muaj qhov pom tseeb thiab muaj zog poob qis hauv kev tso tawm los ntawm kev noj nqaij tsawg," Scarborough hais.
Yuav tsom mus rau dab tsi?
Muaj lwm txoj hauv kev los txo qis emissions, xws li tsav tsheb tsawg dua thiab ya, tab sis kev hloov pauv kev noj haus yuav yooj yim dua rau ntau tus, Scarborough hais. "Kuv xav tias nws yooj yim dua los hloov koj cov zaub mov dua li hloov koj txoj kev mus ncig, txawm tias qee tus yuav tsis pom zoo."
Christopher Jones ntawm University of California ntawm Berkeley hais tias "Txoj kev tshawb fawb no qhia txog cov txiaj ntsig ib puag ncig ntawm kev noj zaub mov tsis zoo," Christopher Jones ntawm University of California ntawm Berkeley hais.
Xyoo 2011, Jones tau muab piv rau txhua txoj hauv kev uas tsev neeg Asmeskas nruab nrab tuaj yeem txo lawv cov emissions. Txawm hais tias cov zaub mov tsis yog qhov loj tshaj plaws ntawm emissions, nws nyob hauv cheeb tsam no uas tib neeg tuaj yeem txuag tau ntau tshaj plaws los ntawm kev nkim zaub mov tsawg thiab noj nqaij tsawg. Jones suav tias txo qis CO2 emissions los ntawm ib tuj txuag ntawm $ 600 thiab $ 700.
Jones hais tias "Cov neeg Asmeskas pov tseg yuav luag ib feem peb ntawm cov khoom noj uas lawv yuav thiab noj 30% calorie ntau tshaj qhov pom zoo," Jones hais. "Raws li cov neeg Amelikas, kev yuav thiab noj zaub mov tsawg tuaj yeem txo cov pa tawm ntau dua li tsuas yog txiav cov nqaij."
