Isilumkiso! Zemfuza ukutya modified akwazi ukumbulala!

Ngokwentelekiso kufutshane ngenkulungwane ye-19 bazisa kuluntu, ukutya okucoliweyo, nto leyo eyakhokelela ekubeni iingxaki zempilo yokuqala esidalwe ngumntu. Ngoko ke, ibengezela, irayisi lisondelelene evuthiswe kwakhokelela ubunzima vitamin A ukuhluleka kwelaseAsiya, ngenxa zeswekile shinyi baqala ukuphuhlisa seswekile kunye yegazi, nokusulungekiswa ze-oli yemifuno bazifinyeza kakhulu ixabiso lesondlo imveliso.

Kule mihla, ingozi esekelwe iphuma uphuhliso olukhawulezayo biotechnology, oko utshabalalisa isiseko yemfuza lezempilo, abantu nje kuphela, kodwa zonke iinkqubo zendalo eziphilayo.

Zemfuza ukutya modified kubangela abantu izifo ezinkulu komzimba, umhlaza, kunye nezifo ezininzi ezintsha kancinane-yaziwa.

Yonke le nto yaqala nesibakala sokuba phakathi kwenkulungwane lokugqibela, izazinzulu British Francis Crick kunye Dzheyms Vatson bebone esibalulekileyo: lonke ulwazi kubume elizayo umzimba igcinwa kwi DNA - embindini yeseli ngumongo. Xa kuye kwacetyiswa ukuba ukulungisa izakhi ngamnye, uyakwazi ukutshintsha iimpawu eziqhelekileyo eziphilayo.

Ngowe-1979, izazinzulu okokuqala bakwazi ukuchonga gene onoxanduva Yindibanisela a insulin zabantu, yaye "wafaka 'yakhe ikhowudi yezofuzo ye E. coli, emva koko waqalisa nokulungelelanisa insulin. Ngoko ke kwabonakala eziphilayo yokuqala yemfuzo - crops.

Ngomhla kwendalo kwezityalo nganye entsha yemfuza etshintshiweyo ithatha iminyaka zomsebenzi kunye nezigidi zeerandi. Bazivelise okanye bazenze ngokusebenzisa umpu sofuzo "luphinde ludubuleke" iseti ekhethekileyo: isakhi kunye kwento isakhi wayefuna ukuqala i gene yangaphambili isakhi-ngqo elimakishayo. Ukuba iseti yemfuza ezinjalo ayitshanga, iiseli yavunyelwa ukuba ikhule ibe isityalo esitsha.

Aziwa ngayo ubunjineli yemfuza yaba eUnited States. Ngoko ke, ngo-1994, kukho ziye zakhula yetumato gene chibi flounder. Ezi kutya izakhi kunokugcinwa ixesha elide, ukuhlala eluhlaza nefudumeleyo ngokukhawuleza uba Undanelise ebomvu.

Okwangoku, uqoqosho lwehlabathi ukhule ngaphezu kwekhulu imigca zezityalo transgenic, kuquka umqhaphu grade yobugcisa kunye necuba. Uluhlu lwe yeMfuzo zesoya ukutya elikhokelwa - isabelo yayo imveliso bungama-98% ye-transgenes. Ziye ke kulandele ingqolowa, sugar beet, oilseed udlwengulo, iitapile, iitumato, ingqolowa.

Yemfuzo iimveliso kwiinkalo ukumelana izinambuzane kwaye ukumelana yokuphatha neekhemikhali ndlongondlongo nxamnye ukhula. Ngoko ukufumana izivuno eziphezulu kakhulu ezi zityalo.

Ingozi kuba ecosystem kukuba elungisiweyo imizila yemfuza yezityalo simbulale kuphela izinambuzane kodwa izinambuzane eziluncedo. Ngaphezu koko, inkqubo kokufaka isakhi amazwe ababandakanyekayo bacteriophages iintsholongwane overactive iisoyi kunye plasmids ezinako ukungena iseli kwaye angene kubo. Ezi zokuthutha kudlule zofuzo elungisiweyo nezityalo eziqhelekileyo, ebangela olungalawulwayo tyaba transfer sofuzo. Ngoko ke kukho utshintsho nokutshatyalaliswa kwendalo yonke.

iimveliso izakhi nakungena abathuthi iintsholongwane kunye umzimba womntu, iyalungisa kungena zofuzo ibangela ukungazinzi isakhiwo yemfuza lulonke. Oku enza ezahlukeneyo zofuzo athi abenoxanduva hayi kuphela umhlaza kodwa izifo entsha ezingaziwayo. Ngokutya ukutya kunye nokuPhuculwe, umntu okunene yosulela iintsholongwane ndlongondlongo kakhulu livulwe.

umzimba wethu ucinga iiproteni yemfuzo iimveliso zokutya ngolwasemzini, okt allergenic. Umzekelo, ukuba wadalwa zesoya genome Brazil nut ukuphucula kwiproteni ye-soy. Kodwa abantu abaye bagulayo Brazil nuts, zama le soy, wafumana uxabane eziqatha, nokuba ebulalayo. Kuphela emva kokuba uthotho kwiimeko ezinobungozi, lo soya evela GMO sele ukhutshiwe kwintengiso.

rhoqo ukuze izityalo ezitsha kusetyenziswa zofuzo zokunciphisa uvakalelo antibiotics. Xa abantu yenza ukukhula ngokukhawuleza iintsholongwane yayintsholongwane eyosulela ukuba babe ukumelana nengaqhelekanga nayiphi olwa nawo.

Kwiminyaka yakutshanje, uluntu jikelele baqala ukuqonda ubungakanani yokwenene ngeengozi zokutya izakhi. Ngoku nathintelwayo ngokomthetho ukuba ithengiswe eYurophu, kunye abavelisi basebenzisa kubo kuphela ukuphunyezwa yeHlabathi yesiThathu. Le ngxoxo kuphela "kuba", nto leyo wahlala kwiinkampani ezinjalo - a yesivuno ezinkulu isilogeni "kwezakhi uya kusindisa ihlabathi yindlala." Noko ke, le ngxelo i intsomi, kuba ingxaki indlala na isigqibo yi kwimveliso ezongezelelweyo, kunye nokusasazwa eyiyo ukutya.

Ngoko ke, qikelela ukuba ukutya kwakho, musa ukubatshabalalisa umzimba wakho kwinqanaba gene, ngenxa yokuba amaGrike amandulo wayesazi: ". Thina - oko kutya"
