Isexwayiso! Okushintshwe ukudla Ushintshe bangambulala!

KolwesiNgisi ekhulwini le-19 alethwe esintwini, ukudla okugayiwe okwaholela izinkinga zezempilo eyayenziwe wadala lokuqala. Ngakho, yona-iphucuziwe, irayisi ngokweqile elicwengisiswe kwaholela mass uvithamini A ukuntula e-Asia, ngoba ushukela elicwengiweyo waqala ukuthuthukisa isifo sikashukela kanye isifo sokuqina kwemithambo yegazi, futhi yokucwenga samafutha zemifino kakhulu kwehlisa umsoco umkhiqizo.

Namuhla, ingozi based livela ukuthuthukiswa ngokushesha we-biotechnology, ubhubhisa ngesisekelo kwezakhi ezempilo, indoda hhayi kuphela, kodwa futhi zonke izimiso zemvelo nezemvelo.

Okushintshwe ukudla Ushintshe kubangele abantu izifo okukhulu nomzimba, umdlavuza nesifo eziningi ezintsha elaziwayo elincane.

Lolu shintsho lwaqala ngesikhathi yokuthi phakathi nekhulu leminyaka elidlule, ososayensi baseBrithani Francis Crick futhi Dzheyms Vatson zathola ezivusa amadlingozi: lonke ulwazi isakhiwo ikusasa umzimba lilondolozwe DNA - maphakathi kuyi-nucleus yengqamuzana. Uma Kuye kwasikiselwa ukuthi ukuma izakhi zofuzo zomuntu ngamunye, ungakwazi ukushintsha izici ezivamile eziphilayo.

Ngo-1979, ngesikhathi ososayensi lokuqala bakwazi ukukhomba isakhi sofuzo esiyimbangela yalesi synthesis a insulini womuntu, futhi "wafaka" e bakhe isimiso sezakhi zofuzo ka E. coli, ngemva kwalokho lona wesifazane waqala synthesize insulini. Ngakho-ke sengathi eziphilayo kuqala izakhi - GMO.

On ukudalwa ngamunye izitshalo ezintsha nge zofuzo ezishintshwe kuthatha iminyaka umsebenzi futhi ezigidi zamarandi namuhla. Khiqiza kubo esebenzisa isibhamu isakhi sofuzo esikhiqiza "Kuphendula" iqoqo esikhethekile: isakhi ne oyifunayo imfanelo isakhi sofuzo ukuthi ziqalise isakhi sofuzo odlule futhi umaka isakhi sofuzo eqondene. Uma iqoqo izakhi zofuzo ezifana uyasinda, amaseli bavunyelwa ukuba ikhule ibe umuntu kwesitshalo esisha.

I Flagship genetic engineering baba-United States. Ngakho, ngo-1994, lapho usukhulile utamatisi isakhi sofuzo deepwater ulwe. Lezi nokudla okushintshwe izakhi zingagcinwa isikhathi eside, asele oluhlaza futhi efudumele ngokushesha iba elihlale abomvu.

Njengamanje, umnotho womhlaba esekhulile engaphezu kwekhulu imigqa zezitshalo transgenic, kuhlanganise lobuchwepheshe grade ukotini kanye nogwayi. Uhlu GMO ukudla kabhontshisi ephethwe - share yayo ekukhiqizeni Imininingwane kuyinto 98% of the transgenes. Basuke kulandele amabele, ushukela isithombo sebhitrudi, oilseed ukudlwengula, amazambane, utamatisi, ukolo.

Izakhi imikhiqizo emasimini amelana izinambuzane eziwuhlupho futhi ukumelana yokusingatha amakhemikhali nolaka ngokumelene ukhula. Ngakho uthole ezithela lasetulu kakhulu lezi zitshalo.

Ingozi ngoba semvelo wukuthi linamathele izakhi zofuzo zezitshalo ingase ibulale nezilokazane nje kuphela kodwa futhi izinambuzane eziwusizo. Ngaphezu kwalokho, ngo-inqubo ufaka isakhi angaphandle bazibandakanye bacteriophages amagciwane yokufakelwa overactive futhi plasmids ekwazi ukungena esitokisini futhi angena kuwo. Lezi zokuthutha kudlule izakhi zofuzo Ushintshe nezitshalo ezijwayelekile, okubangela engalawuliwe ovundlile ukudluliswa zofuzo. Ngakho kukhona ushintsho futhi ukubhujiswa kwaso sonke isimiso semvelo.

imikhiqizo izakhi afakiwe abathutha amagciwane emzimbeni womuntu, ukushumeka ku ufuzo futhi okubangela ukuntengantenga uhlaka lwalo oluphelele zofuzo. Kuvuselela ezihlukahlukene zofuzo okuyizinto akabangeli nje kuphela umdlavuza kodwa futhi isifo esisha engaziwa. Ngokudla ukudla nge GMO, umuntu empeleni ithelela amagciwane nolaka kakhulu emishinini.

umzimba wethu uyabubona amaprotheni izakhi imikhiqizo ukudla njengoba angaphandle, okusho allergenic. Isibonelo, wadalwa Brazil okuletha kukhompiyutha ufuzo nut ukuthuthukisa soy amaprotheni. Kodwa abantu abake iguliswa Brazil nati, zama lokhu soy, wathola ukusabela okukhulu umzimba uxabane nawo, ngisho ukubulala. Kwaze kwaba yilapho sebeshiye ochungechungeni lwamacala eziyingozi, lokhu isoya kusukela GMO ukhishiwe ukudayiswa.

Isikhathi esining impela izitshalo ezintsha usebenzisa zofuzo ukunciphisa ukuzwela nemithi. Ngo abantu kudala ukwanda okusheshayo namagciwane abangela izifo ukuthi babe ukumelana obuphawulekayo yimaphi ama-antibiotic.

Eminyakeni yamuva, umphakathi wamazwe omhlaba ngaqala ukuqaphela ngokwezinga yangempela ngezingozi nokudla okushintshwe izakhi. Manje ziyavalwa ukudayiswa eYurophu, futhi abakhiqizi ukuzisebenzisa kuphela ukuqaliswa Okwesithathu World. I-agumenti kuphela "ngoba", awasalayo zinkampani - a kwesivuno ezinkulu kanye kwesiqubulo esithi "Ubuchwepheshe bokushintsha izakhi zofuzo ngeke ngisindise izwe ngenxa yendlala." Nokho, lesi sitatimende kuyinganekwane, ngoba lendlala akuyona ezinqunywa ukukhiqizwa ezengeziwe, nokusabalalisa efanele ukudla.

Ngakho-ke, qikelela ukudla yakho, ungabhubhisi umzimba wakho ezingeni isakhi sofuzo, ngoba amaGreki asendulo ayazi: ". Thina - esikudlayo"
