Kukhala zamasamba: zobiriwira kuposa kukhala ndi galimoto yosakanizidwa
Marichi 7, 2006 - Kodi mukufuna kuchita gawo lanu kuti muchepetse kutentha kwa dziko pogula galimoto yosakanizidwa? Ndi chiyambi chabwino, koma chopereka chanu chingakhale chofunikira kwambiri ngati mutakhala wosadya zamasamba!
Zowonadi, odya zamasamba amawononga ngakhale pang'ono poyerekezera ndi omwe amayendetsa galimoto yosakanizidwa: kusiyana kwa theka la tani ya mpweya woipitsa. Osachepera ndi zomwe akatswiri a geophysicist aku University of Chicago amati.1, ku USA.
Ofufuzawa anayerekezera kuchuluka kwa mafuta pachaka komwe kumafunikira, kumbali imodzi, kudyetsa zamasamba, ndipo kwinakwake, munthu amene amatsatira zakudya zamtundu wa America, zomwe ndi 28% ya zinyama.
Kuti achite izi, adaganizira kuchuluka kwamafuta oyambira omwe amadyedwa ndi chakudya chonse (ulimi, mafakitale opangira zinthu, zoyendera) komanso utsi wa methane ndi nitrous oxide wobwera chifukwa cha umuna wa zomera. dothi ndi zoweta zomwe.
Kupanga mphamvu kwambiri Ku United States, kupanga chakudya (ulimi, kukonza ndi kugawa) kukuchulukirachulukira mphamvu. Idalamulira 17% ya mphamvu zonse zakale zomwe zidagwiritsidwa ntchito mu 2002, motsutsana ndi 10,5% mu 1999. |
Choncho, munthu wosadya zamasamba chaka chilichonse amatulutsa mpweya woipa wokwana tani imodzi ndi theka (1 kg) wocheperako poyerekeza ndi munthu amene amatsatira zakudya za ku America. Poyerekeza, galimoto ya haibridi, yomwe imayenda pa batire yowonjezedwanso ndi petulo, imatulutsa tani imodzi ya carbon dioxide (CO485) yocheperako pachaka kusiyana ndi galimoto yomwe imayenda pa petulo yokha.
Ngati simudya zamasamba, kuchepetsa kuchuluka kwa nyama zaku America kuchokera ku 28% mpaka 20% kumakhala kofanana, kwa chilengedwe, m'malo mwa galimoto yanu wamba ndi galimoto yosakanizidwa - malipiro ochepa pamwezi!
Kudya nyama yocheperako sikungapindule kokha ndi chilengedwe, komanso thanzi la anthu pawokha. Ofufuzawo akuwonetsa kuti maphunziro ambiri amaphatikiza kudya nyama yofiira ndi matenda amtima, komanso ndi khansa zina.
