Izinto eziphilayo zeTransgenic

Umxholo

• Yaqala nini?
• Ukugxekwa kunye neengxabano
• Imizekelo yezinto eziphilayo (izityalo kunye nezilwanyana)

Inkqubo ye- Izinto eziphilayo zezo zenzelwa utshintsho oluthile kwiimpawu zazo ngokongezwa kwemfuza ehambelana nezinye izinto eziphilayo. Into yokuba izinto eziphilayo eziguqukayo ngokuqinisekileyo ayisiyo yendalo, kodwa kungenxa yesenzo somntu.

Ubunjineli bemfuza yenye yegalelo lalo mbuzo, othi unobizo ukwandisa imveliso yezolimo enegalelo kwezolimo oluzinzileyo Esebenzisa izixhobo ukuphucula ukutya ngokususa izinto eziyityhefu, okanye ukuguqula ubukhulu bamacandelo ayo ukufezekisa ukutya okusempilweni.

Yaqala nini?

Imbali yokuguqulwa kofuzo kwizityalo nakwizilwanyana inemvelaphi yayo kuphela ekupheleni kwenkulungwane yama-20, kuba ngaphambi kokuba eli thuba liqwalaselwe kuphela phantsi kwempembelelo yesayensi.

Inkqubo iqale ngeebhaktiriya, emva koko yandiswa yaya kwi impuku kwaye yayinenyathelo elibalulekileyo xa ngo-1981 oososayensi abathile babonisa oko ngokobudala, ukuhanjiswa kwezinto ezenziweyo zofuzo kwenzeka.

Sele kule minyaka ilishumi idlulileyo, ubunjineli babukwazi lungisa imbewu ngendlela yokuba ngexesha lokulima bakwazi ukumelana nemichiza yokutshabalalisa ukhula, ethi iguqule indlela umjikelo wokuvuna owenziwa ngayo: endaweni yokususa lonke ukhula ngesandla, inokwenziwa ngendlela yemizi-mveliso ngento eyaziwa ngokuba Imbewu '.

Ukugxekwa kunye neengxabano

Kungenxa yeyokugqibela ukuba enye yezona zinto zibalulekileyo ekusetyenzisweni kwe-transgenics ikwi Ukusebenza koqoqosho, kuba ukunyanzeliswa kwemfuza kuhlala kwenziwa ukuze izityalo zikwazi ukumelana nezinambuzane kunye neekhemikhali, okanye iivithamini zongezwa ngendlela engeyiyo yokuphelisa iingxaki zoqoqosho, okanye zinokwandisa zize zenze inkqubo yemveliso.

Azikho i-agronomists ezimbalwa ezilumkisa ngalo mbuzo wokunyanga 'ngokungathi lulo naluphi na uhlobo lwemveliso' ekutyeni okuza kuthi kamva kube kokwabantu, beqinisekisa ukuba ezi zinto ukuphazamisa indalo kunye nokuba semngciphekweni kubantu nakwezinye iintlobo.

Ummiselo: Kwiimeko ezininzi, amazwe Vavanya ukutya okukodwa ngokwahlukeneyoNangona kunjalo, kukho ezinye izizwe (ezinjengeRussia, iFrance okanye iAlgeria) ezibathintelayo ngendlela ebanzi. Ngamanye amaxesha, amazwe akhetha ukunyanzela iilebheli zokutya ezinento ethile ethathwe kwizityalo eziguqukayo, njenge-European Union, Japan, Malaysia ne Australia.

Imizekelo yezinto eziphilayo (izityalo kunye nezilwanyana)

1. Ibhanana: Ukuyenza inganyangeki, zimbini iintlobo ezinqamlezileyo ukuze zicaciswe.
2. Soy: Uguquko kwimbewu, ukuze ikwazi ukumelana nemichiza yokutshabalalisa ukhula. Inxalenye enkulu yeembotyi zesoya ihlwayelwa ngembewu ngqo.
3. Ilayisi: Ukungeniswa kweentlobo ezintathu zemfuza, ukufumana irayisi enomxholo ophezulu we-vitamin A.
4. Islamoni: Umnqamlezo phakathi kwesalmon uvumela enye kubukhulu obungama-200%, enika inzuzo ephezulu kwezoqoqosho.
5. InkomoUbume bemfuzo buhlengahlengisiwe ukuvelisa ubisi ngohlobo lwe-insulin eluncedo kubantu abaneswekile.
6. Ubuqaqawuli: Iintlanzi ziguqulwe ngeprotey ye-jellyfish ebenza bukhanye ngokukhanya okumhlophe okanye nge-ultraviolet.
7. Umbona: Yatshintshwa yemfuza ukuyenza inganyangeki kwizinambuzane, ezazidla ngesityalo.
8. Amazambane: Ii-enzymes zesitashi azisebenzi.
9. Ujongilanga: Imfuza iyatshintshwa ukuze ikwazi ukumelana nembalela.
10. iplamuIi-GMO ziyongezwa ukwandisa imveliso.
11. Iswekile: Itshintshiwe ukuyenza inganyangeki kwimichiza yokubulala ukhula.
12. Amasele: Ngokuwela iintlobo ezivela kwiindidi ezimbini, amasele agqithisileyo ayenziwe, asivumela ukuba sifunde isiphumo seekhemikhali kumalungu abo.
13. UkuzonwabisaIsampulu saguqulwa ngo-2001, sibonisa ukuba into enzima njengale ingatshintshwa ngokwemfuza.
14. Iihagu: Kwangeniswa nemfuza evumela isilwanyana ukuba sivelise i-antigen eya kwenza kube lula kumalungu omntu ukuba amkele.
15. Utamatisi: Ii-enzymes zithintelwe ukucotha ukubola kwexesha.
16. AlfalfaIi-GMO ziyongezwa ukuyenza inganyangeki kwiyeza lokubulala ukhula.
17. KofuUkulungiswa kwemfuzo kuvumela ukonyusa imveliso.
18. Iidiliya: Nge-transgenics kunokwenzeka ukonyusa ukuxhathisa kunye nokuphelisa imbewu ngaphakathi kwesiqhamo.
19. Iigusha: Ngemfuza yomntu, iya kuvumela kwikamva elingekude kakhulu ukuba lisebenzise amalungu abo ukuba afakelwe ebantwini.
20. Iiorenji: Xa ivezwe kwi-ethylene, ikhawulezisa ukonakaliswa kweklorophyll.
