Horumarinta guud ee suuqa bamka kulaylka caalamiga ah waa mid wanaagsan.Tusaale ahaan, mugga iibka ee matoorada kulaylka ee Yurub ayaa kordhay 12% sannad kasta shantii sano ee la soo dhaafay, iyo bambooyinka kulaylka ee dhismayaasha cusub ee Maraykanka, Jarmalka ama Faransiiska ayaa ah tignoolajiyada ugu weyn ee kuleylka.Dhinaca dhismayaasha cusub ee Shiinaha, iyada oo la wanaajinayo shaqooyinka sannadihii la soo dhaafay, mugga iibka ee kuleyliyaha biyaha kululeeyaha ayaa saddex jibaarmay tan iyo 2010, taas oo inta badan ay sabab u tahay tallaabooyinka dhiirigelinta ee Shiinaha.
Isla mar ahaantaana, horumarinta bamka kulaylka dhulka ee Shiinaha ayaa si gaar ah isha ugu haya.10kii sano ee la soo dhaafay, codsiga bamka kulaylka isha dhulka ayaa dhaaftay 500 milyan oo mitir oo laba jibbaaran, iyo beeraha kale codsiga yihiin marxaladda hore ee horumarinta, Tusaale ahaan, dhexdhexaad ah warshadaha iyo heerkulka hoose ee bambooyin kulaylka iyo kulaylka qaybiyey ayaa weli ku tiirsan isticmaalka tooska ah. ee shidaalka fosil.
Bamka kuleylku wuxuu bixin karaa in ka badan 90% baahida kuleylinta meel bannaan ee dhismaha ee caalamiga ah, wuxuuna sii daayaa kaarboon laba ogsaydh yar marka loo eego beddelka shidaalka fosil ee ugu waxtarka badan.Wadamada cagaarka ah ee khariidadda saaran waxay leeyihiin qiiqa kaarboonka ee ka imaanaya matoorada kulaylka ee socda marka loo eego kuleyliyeyaasha gaaska ku shida ee wadamada kale.
Sababo la xiriira kororka dakhliga qofkasta, wadamada kulul iyo qoyan, tirada qaboojiyaha guryaha ayaa laga yaabaa inay saddex jibaarmaan dhowrka sano ee soo socda, gaar ahaan 2050. Kobaca qaboojiyaha ayaa soo saari doona dhaqaale miisaan leh, taas oo keeneysa fursado loogu talagalay matoorada kulaylka. .
Marka la gaadho 2050, bamka kulaylku wuxuu noqon doonaa qalabka ugu muhiimsan ee kulaylinta nidaamka eber saafiga ah, oo xisaabinaya 55% baahida kuleylka, oo ay ku xigto tamarta qorraxda.Iswiidhan waa dalka ugu horumarsan dhankan, 7% baahida kulaylka ee nidaamka kuleylinta degmada waxaa bixiya bamka kulaylka.
Waqtigan xaadirka ah, qiyaastii 180 milyan oo matoorada kulaylka ayaa shaqeynaya.Si loo gaadho dhexdhexaadinta kaarboonka, tiradani waxay u baahan tahay inay gaadho 600 milyan marka la gaadho 2030. Sannadka 2050, 55% dhismayaasha dunidu waxay u baahan yihiin 1.8 bilyan oo matoorada kulaylka ah.Waxaa jira marxalado kale oo muhiim ah oo la xiriira kuleyliyaha iyo dhismaha, taas oo ah, mamnuucida isticmaalka kuleyliyaha shidaalka fosil sanadka 2025 si boos loogu helo tignoolajiyada kale ee tamarta nadiifka ah sida matoorada kulaylka.
