I- izidalwa eziphilayo yilezo eziguqulwa okuthile ezimfanelweni zazo ngokungezwa kofuzo oluhambisana nezinye izinto eziphilayo. Ithuba lokuthi izinto eziphilayo zingaguquguquki akuyona imvelo, kepha kungenxa yesenzo somuntu.
Ubunjiniyela bezofuzo bungomunye weminikelo yabo eyinhloko lo mbuzo, othi unobizo luka ukwandisa umkhiqizo wezitshalo onikela kwezolimo okusimeme esebenzisa izinsiza ukwenza ngcono ukudla ngokuqeda izinto ezinobuthi, noma ukuguqula ubukhulu bezinto zayo ukuthola ukudla okunempilo.

Yaqala nini?
Umlando wokuguqulwa kofuzo kwezitshalo nezilwane unomsuka wawo kuphela ngasekupheleni kwekhulu lama-20, ngoba ngaphambi kwalokhu kungenzeka kwakucatshangelwa kuphela ngaphansi kokucabanga okungamanga kwezesayensi.
Inqubo yaqala ngamagciwane, bese inwetshelwa ku- igundane futhi yaba njengesinyathelo esiyisisekelo lapho ngo-1981 abanye ososayensi bekhombisa lokho ngokwesizukulwane, ukudluliswa kwezinto zofuzo ezihlanganisiwe kwenziwe.
Kakade eminyakeni eyishumi edlule yekhulu leminyaka, ubunjiniyela babukwazi shintsha imbewu ngendlela yokuthi ngesikhathi sokulima bangamelana nokubulala ukhula, okuguqula kakhulu indlela okwenziwa ngayo umjikelezo wokuvuna: esikhundleni sokususa lonke ukhula ngesandla, kungenziwa ngendlela yezimboni ngokusebenzisa lokho okwaziwa ngokuthi ukuhlwanyela '.

Ukugxekwa nezimpikiswano
Kungokwakamuva ukuthi enye yezinkinga ezibaluleke kakhulu ekusetshenzisweni kwama-transgenics iku- Ukusebenza komnotho, ngoba ukuxhaphaza izakhi zofuzo kuvame ukwenziwa ukuze izitshalo zikwazi ukumelana nezinambuzane nezenzo zamakhemikhali, noma ukuthi kunezelwa amavithamini ngokuqedayo aqeda izinkinga zezomnotho, noma zikhulise futhi zihlele umkhiqizo.
Azikho izazi ezimbalwa zezolimo nezolimo ezixwayisa ngalo mbuzo wokwelapha 'sengathi kunanoma yiluphi uhlobo lomkhiqizo' ekudleni okuzoba okwomuntu kamuva, beqinisekisa ukuthi le mikhuba kuphazamisa imvelo futhi kuyingozi kubantu nakwezinye izinhlobo zezinto eziphilayo.
Umthethonqubo: Ezimweni eziningi, amazwe hlola ngakunye kwalokhu kudla ngawodwanaKodwa-ke, kunezizwe ezithile (njengeRussia, iFrance noma i-Algeria) ezizenqabela ngendlela ejwayelekile. Kwezinye izimo, amazwe akhetha ukuphoqelela ukufakwa ilebula kokudla okuqukethe ingxenye ethile ethathwe ezitshalweni ezishintshayo, njenge-European Union, Japan, Malaysia ne-Australia.
Izibonelo zezinto eziphilayo (izitshalo nezilwane)
- Ibhanana: Ukwenza ikwazi ukumelana kakhudlwana, izinhlobo ezimbili ziwela ukunwetshwa kwaso.
- Soy: Ukuguqulwa embewini, ukumelana kakhulu nokubulala ukhula. Ingxenye enkulu kabhontshisi ihlwanyelwa ngokuhlwanyela ngqo.
- Ilayisi: Ukwethulwa kwezakhi zofuzo ezintathu ezintsha, ukuthola irayisi elinokuqukethwe okuphezulu kukavithamini A.
- Uhlobo lwenhlanzi: Isiphambano phakathi kwe-salmon sivumela umuntu ngosayizi ongu-200% ngaphezulu, okunikeza inzuzo ephezulu kwezomnotho.
- InkomoUkwakheka kofuzo kwalungiswa ukukhiqiza ubisi ngohlobo lwe-insulin esebenziseka kubantu abanesifo sikashukela.
- I-Glofish: Izinhlanzi ezilungiswe nge-jellyfish protein ezibenza zikhanye ngokukhanya okumhlophe noma kwe-ultraviolet.
- Ukolweni: Yaguqulwa ngezakhi zofuzo ukuze ikwazi ukumelana nezinambuzane, ezazidla lesi sitshalo.
- Izambane: Ama-enzyme wesitashi awavumelekile.
- Ubhekilanga: Izakhi zofuzo ziyashintshwa ukuze zikwazi ukumelana nesomiso.
- ipulamuAma-GMO ayengezwa ukukhulisa umkhiqizo wawo.
- Ushukela: It is modified ukuze ikwazi ukumelana nokubulala ukhula.
- Amaxoxo: Ngokunqamula izakhi zofuzo kusuka ezinhlotsheni ezimbili, amaxoxo aguqukayo adalwa, asivumela ukuthi sifunde umphumela wamakhemikhali ezithweni zawo.
- I-Primate: I-specimen yaguqulwa ngo-2001, okufakazela ukuthi isimo esiyinkimbinkimbi njengalesi singaguqulwa ngokwezakhi zofuzo.
- Izingulube: Kufakwe nezakhi zofuzo ezivumela isilwane ukuthi sikhiqize i-antigen ezokwenza kube lula ukuthi izitho zabantu zamukele.
- Utamatisi: Ama-enzyme avinjelwe ukunciphisa isikhathi sokubola.
- I-Alfalfa: Ama-GMO ayengezwa ukwenza kungazweli kumuthi wokubulala ukhula.
- Ikhofi: Ukuguqulwa kofuzo kuvumela ukukhulisa umkhiqizo.
- Amagilebhisi: Ngama-transgenics kungenzeka ukwandisa ukumelana nokuqeda imbewu ngaphakathi kwesithelo.
- Izimvu: Ngezakhi zofuzo zabantu, kungavumela esikhathini esizayo esiseduze kakhulu ukuthi basebenzise izitho zabo ukufakelwa kubantu.
- Amawolintshi: Lapho ivezwa ku-ethylene, isheshisa ukonakala kwe-chlorophyll.
