Ukudla kweTransgenic, okwaziwa nangokuthi ukudla okushintshwe izakhi zofuzo, yilawo anezingcezu ze-DNA ezivela kwezinye izinto eziphilayo ezihlanganiswe ne-DNA yazo. Isibonelo, ezinye izitshalo zine-DNA evela kubhaktheriya noma isikhunta esikhiqiza ukubulala ukhula kwemvelo, kuzenze zivikeleke ngokuzenzakalela ezilwaneni ezihlasela izilimo.
Ukuguqulwa kofuzo lokudla okuthile kwenziwa ngenhloso yokwenza ngcono ukumelana kwawo, ikhwalithi nobungako bawo obukhiqizwayo, kepha-ke, kungaveza ubungozi bezempilo, njengokukhuphula ukungezwani komzimba nokutholakala kwemithi yokubulala izinambuzane ngokwesibonelo. Ngalesi sizathu, okulungile ukukhetha ngangokunokwenzeka ekudleni okuphilayo.
Kungani akhiqizwa
Ukudla okushintshwe izakhi zofuzo kuvame ukudlula kule nqubo, ngenhloso yoku:
- Thuthukisa ikhwalithi yomkhiqizo wokugcina, ukuze kuqukathe izakhi zomzimba eziningi, isibonelo;
- Khulisa ukumelana kwakho nezinambuzane;
- Thuthukisa ukumelana nezibulala-zinambuzane ezisetshenzisiwe;
- Khulisa isikhathi sokukhiqiza nesokugcina.
Ukukhiqiza lolu hlobo lokudla, abakhiqizi badinga ukuthenga imbewu ezinkampanini ezisebenza nobunjiniyela bezakhi zofuzo ukukhiqiza ama-transgenics, agcina enyusa intengo yomkhiqizo.
Kuyini ukudla kwe-GM?
Ukudla okuyisisekelo okuyisisekelo okuthengiswa eBrazil yisoya, ummbila nokotini, okuveza imikhiqizo efana namafutha okupheka, okukhishwa kwesoya, amaprotheni o-soy aqoshiwe, ubisi lwe-soy, isoseji, imajarini, ipasta, ama-crackers nezinhlamvu. Noma ikuphi ukudla okuqukethe izithako ezifana nesitashi sommbila, isiraphu yommbila kanye nesoya ekwakhiweni, kungenzeka kube nama-transgenics ekubunjweni kwawo.
Ngokomthetho waseBrazil, ilebula lokudla okungenani eline-1% yezingxenye ze-transgenic kufanele libe nophawu lokuhlonza i-transgenic, elimele unxantathu ophuzi nonobumba T omnyama phakathi.
Izibonelo zokudla kwe-transgenic ngezinhloso zokwelapha
Ilayisi liyisibonelo sokudla okushintshwe izakhi zofuzo ngezinhloso zokwelapha, njengokulwa negciwane lesandulela ngculaza noma ukufaka ivithamini A.
Endabeni yelayisi yokulwa ne-HIV, imbewu ikhiqiza amaprotheni ama-3, i-monoclonal antibody 2G12 kanye ne-lectins griffithsin ne-cyanovirin-N, abopha igciwane futhi anciphise amandla alo okuthelela amaseli omzimba. Lezi zinhlamvu zingatshalwa ngezindleko eziphansi kakhulu, okwenza ukwelapha lesi sifo kushibhe kakhulu. Ngaphezu kwalokho, lezi zinhlamvu zingagaywa zisetshenziswe kokhilimu nakwizinto zokugcoba ukuze zisetshenziswe esikhunjeni, zilwe negciwane elivame ukutholakala ekusithekeni kwezitho zobulili zezitho.
Olunye uhlobo lwelayisi elenza i-transgenic ngezinhloso zokwelapha yilokho okubizwa ngokuthi yiGolden Rice, eyashintshwa ukuze icebe nge-beta-carotene, uhlobo lukavithamini A. Leli rayisi lenziwa ikakhulukazi ukulwa nokuntuleka kwaleli vithamini ezindaweni zobumpofu obukhulu , njengasezindaweni zase-Asia.
Izingozi zezempilo
Ukusetshenziswa kokudla kwe-transgenic kungaletha izingozi zezempilo ezilandelayo:
- Ukungezwani komzimba okwandisiwe, ngenxa yamaprotheni amasha angenziwa ngama-transgenics;
- Ukwanda kokumelana nemithi elwa namagciwane, okufaka isandla ekunciphiseni ukusebenza kwale mithi ekwelapheni ukutheleleka kwamagciwane;
- Ukwanda kwezinto ezinobuthi, ezingagcina sezilimaza umuntu, izinambuzane nezitshalo;
- Inani eliphakeme kakhulu lezibulala-zinambuzane emikhiqizweni, njengoba ama-transgenics emelana kakhulu nezibulala-zinambuzane, okuvumela abakhiqizi ukuthi basebenzise inani elikhudlwana ukuvikela ukutshalwa kwizinambuzane nokhula.
Ukugwema lezi zingcuphe, indlela engcono yokuphuma ukudla ukudla okuphilayo, okubuye kukhuthaze ukwanda kokutholakala kwalo mzila womkhiqizo futhi kusekele abakhiqizi abancane abangasebenzisi ama-transgenics kanye ne-pesticides emasimini abo.
Izingozi Zendawo
Ukukhiqizwa kokudla kwe-transgenic kwandisa ukumelana kwabo, okuvumela ukusetshenziswa okukhulu kwezibulala-zinambuzane kanye ne-pesticides emasimini, okwandisa ubungozi bokungcola kwenhlabathi namanzi ngalezi zinto zamakhemikhali, ezizogcina zidliwe ngobukhulu obukhulu ngabantu izoshiya inhlabathi ihlwempu.
Ngaphezu kwalokho, ukusetshenziswa ngokweqile kwezibulala-zinambuzane kanye ne-pesticides kungashukumisa ukuvela kwamakhambi nezinambuzane eziphikisana kakhulu nalezi zinto, okwenza kube nzima ukulawula ikhwalithi yensimu.
Okokugcina, abalimi abancane nabo basenkingeni ngoba, uma bethenga imbewu ekudleni okuyi-GM, bazobe bekhokha imali ezinkampanini ezinkulu ezikhiqiza lezi zinhlamvu, futhi bayohlala bephoqelekile ukuthenga imbewu entsha minyaka yonke, ngokwezivumelwano ezisunguliwe .
