Digniin! Hiddaha cuntooyinka modified dili karaa!

Xad u dhow qarnigii 19aad keenay aadanaha, cuntooyinka la safeeyey, taas oo keentay in ay dhibaatooyinka caafimaadka kiimikaysan abuuray marka hore. Sidaas daraaddeed, safeeyey, bariis haday safeeyey keentay in tiro ka mid ah vitamin deficiency A ee Asia, sababtoo ah ee sonkor ah la safeeyey bilaabay si ay u horumariyaan diabetes iyo atherosclerosis, iyo turxaan oo saliidda cuntada si weyn hoos ugu qiimo nafaqo ee alaabta.

Maalmahan, khatarta ku salaysan waxay ka timaadaa horumarinta deg deg ah ee bayotechnoolajiyadda, Halaagtay saleysan hidaha ee caafimaadka, nin ma aha oo kaliya, laakiin sidoo kale dhammaan hababka dabiiciga ah ee dabiiciga ah.

Hiddaha cuntooyinka modified keeni dadka cudurada weyn xasaasiyad, kansarka, iyo cudur badan oo yar-yaqaan cusub.

Waxaa oo dhan ku bilaabantay xaqiiqda ah in dhexe ee qarnigii la soo dhaafay, saynisyahano British Francis Crick iyo Dzheyms Vatson sameeyey daahfurka kuweyn: dhammaan macluumaadka ku saabsan qaab dhismeedka mustaqbalka ee jirka waxa lagu kaydiyaa DNA - xarunta of bu'da unugga. Marka waxaa la soo jeediyay in beddelaan hiddo-shaqsi, waxaad bedeli kartaa qaababka caadiga ah ee noolaha.

In 1979, markii ugu horeysay ee saynisyahano ay awoodaan si ay u aqoonsadaan hiddo mas'uulka ka ah ereygu wuxuu ahaa ee insulin ah aadanaha, iyo "gundhig" in uu code genetic of E. coli, ka dib markii taas waxay bilowday inay synthesize insulin. Sidaasay u soo muuqatay noolaha ugu horeysay hiddo modified - GMOs.

On abuurka kasta dhirta cusub genetics doorsoon qaadataa sano oo shaqo ah oo malaayiin doolar. iyaga soo saaro by hab qoriga hiddo-oo "laayey" set gaar ah oo ka mid ah: hidda leh hiddo-ka sifo jeclaaday inuu ka bilowdo hiddo hore iyo calaamadeysanayaan hiddo-gaarka ah. Haddii set oo ah hiddo-sida soo waaqsado, unugyada ayaa la oggol yahay si ay u koraan galay warshad cusub.

flagship ee injineernimada hidde noqday Maraykanka. Sidaas daraaddeed, 1994, waxaa la koray yaanyo baadinimadooda barwaaqadoodu hiddo. Kuwani cuntooyinka hiddo modified lagu kaydin karaa waqti dheer, ku haray cagaaran iyo diiran degdeg noqdo cokan cas.

Waqtigan xaadirka ah, dhaqaalaha adduunka koray in ka badan boqol khadadka dhirta transgenic, oo ay ku jiraan suuf fasalka farsamo iyo tubaakada. Liiska iminka faaruq ah cuntada siibtey madax - ay share in wax soo saarka guud waa 98% transgenes ah. Waxay la raacay by hadhuudh, dabocase sonkorta, kufsi oilseed, baradho, yaanyo, sarreen ah.

Hiddaha modified alaabta ee beeraha adkaysi u cayayaanka iyo adkeysan taabato kiimikada dagaal ka dhan ah haramaha. Sidaas daraaddeed aad u hesho wax-soosaarkooda ay aad u sarayso ah dhirta, kuwaas oo.

Khatarta ugu for hannaanka waa in gundhig ee hiddo-ee dhirta laga yaabaa in ay dilaan cayayaanka ma aha oo kaliya, laakiin sidoo kale cayayaanka faa'iido. Waxaa intaa dheer, in nidaamka of galinta hiddo-qalaad bacteriophages lug fayrusyada macmal firfircoonida iyo plasmids kuwaas oo ay ku soo galaan gacanta iyo aad u hesho waxa galo wuu kari waayay. conveyors waxay u gudbi ah hiddo-modified iyo dhirta caadiga ah, ee keenaya kala iibsiga hiddo-siman caasiyoobay. Sidaas waxaa jira isbedel iyo burburinta lafaguro oo dhan.

waxyaabaha Hiddaha modified waxaa galay gaadiidlayda fayrusyada iyo jidhka bini'aadamka, saxafiyiinta galay hiddawadayaasha iyo keenaya guud xasilooni-dhismeedka hidaha. Tani waxay shidaa noocyo kala duwan oo hiddo-oo mas'uul ka ma aha oo kaliya ee kansarka, laakiin sidoo kale cudurka cusub oo aan la garaneyn yihiin. By cunista cuntooyinka la GMOs, qofka si dhab ah qaadsiiyo fayrusyada macmal ah mid aad dagaal badan.

Our jirka arkaa borotiinada hiddo modified cuntooyinka sida ajnabi ah, ie xasaasiyad. Tusaale ahaan, waxaa la abuuray hiddawadayaasha Landkruusaro lowska Brazil si loo hagaajiyo protein soy. Laakiin dadka ayaa xasaasiyad Brazil nuts, isku day in soy this, helay cadaanyo ba'an ama daran kiciyay waxaa, xataa dhimasho. Kaliya ka dib markii taxane ah oo ka mid ah xaaladaha khatarta ah, soya ka siibtey ayaa laga soo saarey sale.

Inta badan dalagga cusub oo la isticmaalayo hiddo in la yareeyo u nuglaanta si antibiotics. In aadanuhu waxa sababa koritaanka si degdeg ah bakteeriyada pathogenic in ay leeyihiin iska caabin aan caadi ahayn in antibiotic kasta.

Sanadihii la soo dhaafay, beesha caalamka waxay bilaabeen inay ogaadaan ilaa xadka dhabta ah ee khatarta cuntooyinka hiddo modified. Hadda waxay la mamnuucay for sale in Europe, iyo saarayaasha u isticmaalaan si gaar ah loogu hirgelinta dunida saddexaad. dood kaliya "for", oo ku sugnaa gudaha shirkadaha sida - a goosashada ballaaran iyo dhigyo ay "injineernimada hidda dunida gaajo badbaadin doonaa." Si kastaba ha ahaatee, hadalkan waa quraafaad ah, sababtoo ah dhibaatada gaajo aan go'aansaday by-soo-saarka ah oo dheeraad ah, iyo qaybinta habboon oo cunto ah.

Sidaas ahaan fikirin cuntada, ha jirkaaga uma ay baabbi'in heer hiddo, maxaa yeelay, dadka Gariigta ah qadiimiga ah aqoon, ". Waxaan - waxa aannu u cunno"
