Pane chitendero chakakurumbira chekuti nekutenga mota ine hushamwari hwezvakatipoteredza, tiri kuponesa nyika kubva kune njodzi yezvakatipoteredza. Pane chokwadi mune izvi. Asi mugove chete. Planetary ecology inotyisidzirwa kwete nemotokari chete, asiwo ... chikafu chakajairika. Vashoma vanhu vanoziva kuti gore rega rega indasitiri yechikafu yeUS inoburitsa anenge 2,8 matani ecarbon dioxide panguva yekugadzira, ichipa avhareji mhuri yeAmerica chikafu chechinyakare. Uye izvi zvisinei nekuti nzendo nemotokari kumhuri imwechete inoburitsa matani maviri egasi rimwe chete. Saka, kunyangwe kubva pakuona kunoshanda, kune inokurumidza uye yakachipa sarudzo yekubatsira kuchengetedza zvakatipoteredza - kushandura kune chikafu chine hushoma hwemukati kabhoni.
Iyo yekurima yakaoma yenyika inoburitsa inenge 30% yeese kabhoni dhaikisaidhi. Ivo vanogadzira greenhouse effect. Izvi zvakanyanya kudarika mota dzese dzinoburitsa. Saka kana zvasvika pakudzikisa kabhoni tsoka yako nhasi, zvakachengeteka kutaura kuti izvo zvaunodya zvine basa seizvo zvaunotyaira. Pane imwe chokwadi chakakosha mukuda kwepasi-kabhoni "kudya": magidhi akatinakira. Navo pachavo, zvikafu zvinosiya yakakura "carbon footprint" (nyama tsvuku, nyama yenguruve, zvigadzirwa zvemukaka, makemikari akagadzirwa snacks) anoremerwa nemafuta nemakori. Kunyange zvazvo kudya kwe "green" kunofanira kusanganisira miriwo, michero, uye zviyo.
Kugadzirwa kwechikafu kweMcDonald's kunoburitsa kabhoni yakawanda kupfuura, sezvatataura, kutyaira mota kunze kweguta. Nekudaro, kuti utende chiyero, iwe unofanirwa kunzwisisa kuti yakakura sei uye ine simba-yakawanda sei indasitiri yechikafu yepasi rose. Inopfuura 37% yenyika yose yepasi inoshandiswa pakurima, yakawanda yenzvimbo iyi yaimbova masango. Kutemwa kwemasango kunokonzera kuwedzera kwekabhoni. Fetereza nemichina zvakare inosiya yakakosha kabhoni tsoka, sezvinoita mota dzemugungwa dzinoendesa magirosari patafura yako. Zvinotora paavhareji 7-10 nguva yakawanda yefossil simba rekugadzira uye kuendesa chikafu pane yatinowana kubva mukudya chikafu ichocho.
Nzira inonyanya kushanda yekudzikisa kabhoni mumenyu yako ndeyekudya nyama shoma, kunyanya yemombe. Kuchengeta zvipfuyo kunoda simba rakawanda kudarika kurima zviyo, michero kana miriwo. Kune yega yega calorie yesimba iri muchikafu chakadaro, 2 macalories efossil fuel simba anodiwa. Panyaya yemombe, chiyero chinogona kusvika pa80 kusvika pa1. Pamusoro pazvo, zvipfuyo zvizhinji muUnited States zvinopfuyiwa pazviyo zvakawanda – matani mamiriyoni mazana matanhatu nemakumi manomwe muna 670. Uye fetereza yaishandiswa pakurima nyama yemombe, semuenzaniso, gadzira mamwe matambudziko ezvakatipoteredza, kusanganisira kumhanya kunoenda kunzvimbo dzakafa mumvura yemahombekombe, senge muGulf yeMexico. Zvipfuyo zvinopfuudzwa pazviyo zvinobudisa methane, gasi regreenhouse rine simba rakapetwa ka2002 kupfuura carbon dioxide.
Muna 2005, chidzidzo cheYunivhesiti yeChicago chakawana kuti kana munhu mumwe chete akarega kudya nyama uye akachinja kune kudya kwezvinomera, vanogona kuchengetedza huwandu hwakafanana hwecarbon dioxide sekunge vakashandura Toyota Camry neToyota Prius. Zviri pachena kuti kuderedza chiyero chenyama tsvuku inodyiwa (uye vaAmerica vanodya zvinopfuura 27 kg yemombe pagore) inewo hutano hwakanaka. Nyanzvi dzinofungidzira kuti kutsiva 100 magiramu emombe, zai rimwe, magiramu makumi matatu echizi zuva nezuva nehuwandu hwemichero, miriwo uye zviyo zvinoderedza kubatwa kwemafuta uye kuwedzera kudya kwefiber. Panguva imwecheteyo, mahekita 30 evhu rinorimika aizochengetwa, uye huwandu hwemarara emhuka hwaizoderedzwa kusvika kumatani mashanu.
Zvakakosha kunzwisisa: zvaunodya hazvirevi zvishoma pane kuti chikafu ichi chinobva kupi. Chikafu chedu chinofamba avhareji yemakiromita 2500 kusvika 3000 kubva panyika kuenda kuchitoro chikuru, asi rwendo urwu runongotora 4% chete yecarbon footprint yechikafu. “Idya zvokudya zvakapfava zvinoshandisa zvinhu zvishoma kugadzira, idya miriwo yakawanda nemichero, uye nyama shoma nezvinogadzirwa nomukaka,” anodaro Keith Gigan, nyanzvi yezvokudya uye munyori webhuku rava kuzodhindwa rinonzi Eat Healthy and Lose Weight. "Zviri nyore."
Kuisa solar panel kana kutenga mahybrid kungave kwatisingasvikire, asi isu tinogona kushandura izvo zvinopinda mumiviri yedu nhasi - uye sarudzo dzakaita seizvi zvine basa kuhutano hwepasi redu uye isu pachedu.
