Imisundululu inokonyusa imveliso yokutya yehlabathi ngeetoni ezizigidi ezili-140 ngonyaka

Izazinzulu zase-US zifumanise ukuba imisundululu inokuba negalelo kwi-140 yezigidi zeetoni zokutya kwihlabathi jikelele ngonyaka, kubandakanywa i-6.5% yeenkozo kunye ne-2.3% yeembotyi.Abaphandi bakholelwa ukuba utyalo-mali kwimigaqo-nkqubo yezolimo kunye nezenzo ezixhasa ubukho bemisundululu kunye nokwahluka komhlaba ngokubanzi kubalulekile ekufezekiseni iinjongo zezolimo ezizinzileyo.

Imisundululu ngabakhi ababalulekileyo bomhlaba osempilweni kwaye ixhasa ukukhula kwezityalo kwimiba emininzi, njengokuchaphazela ubume bomhlaba, ukufunyanwa kwamanzi, ukukhwela ibhayisekile kwezinto eziphilayo, kunye nokufumaneka kwezondlo.Imisundululu inokuphinda iqhube izityalo ukuvelisa iihomoni ezikhuthaza ukukhula, zibancede ukuba baxhathise iintsholongwane ezixhaphakileyo emhlabeni.Kodwa igalelo labo kwimveliso yezolimo yehlabathi ayikachazwa.

Ukuvavanya ifuthe lemisundululu kwimveliso yesityalo esibalulekileyo kwihlabathi, uSteven Fonte kunye noogxa baseColorado State University bahlalutya iimephu zobuninzi bemisundululu, iimpawu zomhlaba, kunye nemveliso yezityalo kwidatha yangaphambili.Baye bafumanisa ukuba imisundululu inegalelo elimalunga ne-6.5% yemveliso yokutya okuziinkozo kwihlabathi (kuquka umbona, irayisi, ingqolowa, nerhasi), kunye ne-2.3% yemveliso yeembotyi (kuquka iimbotyi zesoya, iiertyisi, ii-ertyisi, iilentile, kunye nealfalfa), ezilingana ne-140 lezigidi zeetoni. yeenkozo ngonyaka.Igalelo lentshulube liphezulu kakhulu kumazantsi ehlabathi, linegalelo le-10% kwimveliso yokutya okuziinkozo kwi-Afrika ekwi-sub Sahara kunye ne-8% kwi-Latin America nakwi-Caribbean.

Ezi ziphumo ziphakathi kweenzame zokuqala zokulinganisa igalelo lezinto eziphilayo zomhlaba ezinenzuzo kwimveliso yezolimo yehlabathi.Nangona ezi zinto zifunyanisiweyo zisekwe kuhlalutyo lweenkcukacha ezininzi ezisemantla ehlabathi, abaphandi bakholelwa ukuba imisundululu ngoonobangela ababalulekileyo kwimveliso yokutya yehlabathi.Abantu kufuneka baphande kwaye bakhuthaze iindlela zokulawula ezolimo zendalo, bomeleze umhlaba wonke webhayoloji, kubandakanywa nemisundululu, ukuxhasa iinkonzo ezahlukeneyo ze-ecosystem ezikhuthaza uzinzo lwexesha elide kunye nokomelela kwezolimo.
