Posachedwapa, mabungwe ofufuza ndi makampani oteteza chilengedwe ochokera m'maiko ambiri padziko lonse lapansi atulutsa chitukuko chofunikira kwambiri, zomwe zakwaniritsa chitukuko chofunikira kwambiri pamavuto akuluakulu aukadaulo okhudzana ndi tirigu.mbale zophikidwa zomwe zimawonongekaKupambana kumeneku kumathetsa mavuto a kusagwira bwino ntchito komanso kusasinthasintha bwino kwa zinthu zachikhalidwe, zomwe zimapangitsa kuti zinthu zobiriwira, zotsika mtengo, komanso zokulirapo zitheke.njira yatsopanokuti athetse kuipitsa kwa pulasitiki padziko lonse lapansi, zomwe zakopa chidwi cha anthu ambiri m'munda woteteza chilengedwe padziko lonse lapansi.

Zanenedwa kuti izichitukuko chaukadauloidatsogozedwa ndi Germany, China, ndi Canada, ndi magulu ofufuza ochokera kumayiko akuluakulu opanga tirigu monga Brazil ndi Australia. Poyang'ana kwambiri pazovuta zamakampani apadziko lonse lapansi opanga mbale zophikidwa, gululi linaphatikiza zabwino zaukadaulo zamayiko osiyanasiyana kuti achite kafukufuku ndi chitukuko chogwirizana. Makamaka, gulu la Germany linatsogolera kukweza njira yolimbana ndi kutentha, gulu la ku China linapanga njira zotsogola pakuchotsa ndi kuumba bwino tirigu.udzu wa tirigu, ndipo gulu la ku Canada linakonza bwino kuwonongeka kwa malonda ndi kuwongolera ndalama, ndikupanga njira yogwirira ntchito limodzi yaukadaulo m'madera osiyanasiyana komanso m'magawo osiyanasiyana.

Poyerekeza ndi zachikhalidwembale za patebulo za tirigu,ukadaulo watsopanoChogulitsachi chimapeza phindu lalikulu pa ntchito yake, chimatha kupirira kutentha kwa 125℃, kuthetsa mavuto amakampani okhudzana ndi kusintha kwa kutentha ndi kutuluka kwa madzi. Chadutsanso ziphaso zodziwika bwino padziko lonse lapansi, zomwe zimapangitsa kuti chikhale choyenera kudyetsedwa m'madera osiyanasiyana monga EU, North America, ndi Southeast Asia. Chogulitsachi chimagwiritsa ntchito zinyalala zaulimi monga udzu wa tirigu ndi chimanga cha tirigu ngati zopangira, sichifuna zowonjezera mankhwala. Chimatha kupangidwa ndi manyowa kwathunthu ndipo chimawonongeka mkati mwa masiku 90 kuchokera pamene chagwiritsidwa ntchito, zomwe zimapangitsa kuti "chichokere ku chilengedwe ndikubwerera ku chilengedwe."

Pakadali pano, ukadaulo uwu wapatsidwa chilolezo ku makampani 12 padziko lonse lapansi kuti apange tirigu wambiri, womwe umakhudza mayiko akuluakulu opanga tirigu ndi madera omwe ali ndi zosowa zachilengedwe zambiri. Malo opangira tirigu ku China ndi Brazil makamaka amapereka misika ya ku Asia ndi South America, pomwe malo opangira tirigu ku Germany ndi Canada amatumikira ku Europe ndi North America. Mphamvu yopangira tirigu pachaka imaposa zidutswa 500 miliyoni, zomwe zimathandiza kuti alimi azigwiritsa ntchito bwino zinyalala zaulimi m'maiko osiyanasiyana, kuthandiza alimi kuwonjezera ndalama zawo ndikukweza ndalama zawo.kuteteza zachilengedwemafakitale.

Woimira bungwe la United Nations Environment Programme anati kupita patsogolo kwa ukadaulo wapadziko lonse lapansi pa mbale za tirigu kukugwirizana ndi zomwe zikuchitika padziko lonse lapansi za "kuletsa ndi kuchepetsa pulasitiki." Izi zimagwiritsa ntchito ubwino wa mayiko akuluakulu opanga tirigu komanso kuphatikiza mphamvu zaukadaulo za mayiko osiyanasiyana, ndikukhazikitsa muyezo wa chitukuko chogwirizana cha dziko lonse lapansi.makampani ovundandi kufulumizitsa kufalikira kwa chilengedwe padziko lonse lapansimbale zabwino.
