Temoso! Liphatsa tsa lefutso lijo tse fetotsoeng ka bolaea!

E batlang e le haufi le lekholong la bo19 la lilemo tlisoa ho moloko oa batho, lijo tse hloekisitsoeng, e ile ea etsa hore pele mathata artificially a bōpa bophelo. Ho joalo, e bentšitsoeng, ho feta tekano e hloekisitsoeng raese ile sa etsa hore le boima ba vithamine A khaello Asia, ka lebaka la tsoekere e hloekisitsoeng qala ho ntshetsa pele le lefu la tsoekere 'me atherosclerosis,' me ho hloekisoa ha oli ea limela haholo theolela boleng phepo e nepahetseng ya sehlahiswa.

Mehleng ena, kotsi e thehiloeng tlisoang ke ho ntshetsopele e potlakileng ea theknoloji ea baeloji, o timetsa motheong liphatsa tsa lefutso tsa bophelo bo botle, monna e seng feela, empa le bohle ba tlhaho tsamaiso ea tlholeho.

Liphatsa tsa lefutso lijo tse fetotsoeng etsa hore batho ba mafu a maholohali alejiki, kankere, 'me a mangata a macha hanyane tsebahalang lefu.

Kaofela qala le taba ea hore bohareng ba tse lekholo tse fetileng, bo-rasaense ba Brithani Francis Crick le Dzheyms Vatson entse sibolloa bohlokoa: tlhahisoleseding tsohle ka sebopeho nakong e tlang ea 'mele e bolokwa ka DNA - bohareng ba khubung seleng. Hang ha e se e etsa tlhahiso ea hore fetolang liphatsa tsa lefutso motho, o ka fetola likarolo tloaelehileng la lintho tse phelang.

Ka 1979, pele bo-rasaense ba nako ba ile ba khona ho khetholla liphatsa tsa lefutso le boikarabelo ba ho tswakana a ka insulin batho, 'me "aa ageletsweng" la hae le khoutu liphatsa tsa lefutso tsa E. coli, ka mor'a moo o ile a qala ho synthesize insulin. Kahoo a hlaha pele tse phelang liphatsa tsa lefutso fetotsoeng - GMOs.

Ka ho bōptjoa ha e mong le e dimela ncha e nang le liphatsa tsa lefutso fetoloang nka lilemo tsa mosebetsi 'me ba limilione tsa liranta. Hlahisa ka 'sethunya phatsa ea lefutso e "letlobo" sete khethehileng tsa e le: a phatsa ea lefutso ka lakatsa tšobotsi phatsa ea lefutso ho qala ho fihlela phatsa ea lefutso fetileng le lesupa phatsa ea lefutso-itseng. Ha sete ya liphatsa tsa lefutso joalo pholohang, lisele tsa tsona li ne li lumelloa ho hōla hore e be semela se secha.

The flagship tsa fetola liphatsa tsa lefutso e ile ea fetoha United States. Ho joalo, ka 1994, ho na le ba hōlileng ka tamati phatsa ea lefutso deepwater flounder. Tsena lijo tse liphatsa tsa lefutso fetotsoeng ka ho bolokoa bakeng sa nako e telele, setseng e tala 'me mofuthu ka potlako e ba phelelang ho e khubelu.

Hona joale, haholo moruong wa lefatshe hōlileng ka mela e fetang lekholo ea limela transgenic, ho akarelletsa le tsa k'hothono, botekgeniki sehlopheng le koae. Lenane la GMO lijo linaoa leba - bolelelane lona ka ho hlahisa palo yohle e 98% ya transgenes ena. Di lateloa ke poone, beet tsoekere, oilseed le peto, litapole, tamati, koro.

Liphatsa tsa lefutso fetotsoeng lihlahisoa masimong manganga ho tse senyang lijalo likokoanyana le mamella tšoarang lik'hemik'hale mabifi khahlanong le mofoka. Kahoo fumana chai ka ho fetisisa phahameng ea limela tsena.

Kotsi bakeng sa tikoloho, ke hore aa ageletsweng ka liphatsa tsa lefutso tsa limela e ka bolaea tse senyang lijalo, e seng feela empa hape likokoanyana tse molemo. Ho feta moo, ka ho tshebetso ya ho ho kenyeletsa tlhaloso ka phatsa ea lefutso baditjhaba akaretswago bacteriophages overactive livaerase maiketsetso le plasmids tse khonang ho kena seleng le fumana ka ho sona. conveyors tsena feta liphatsa tsa lefutso fetotsoeng le dimela ho tloaelehile, a etsa hore se laole tshekaletseng phetiso phatsa ea lefutso. Kahoo ho na le phetoho e le ka ho timetsoa ha lintho tse phelang tikolohong kaofela.

Liphatsa tsa lefutso fetotsoeng lihlahisoa tse kena li tsamaisang likokoana-hloko le 'mele oa motho, embedding ka liphatsa tsa lefutso e le ho etsa hore se tsitse ka kakaretso sebopeho liphatsa tsa lefutso. Sena activates mefuta e fapaneng ya liphatsa tsa lefutso tse nang le boikarabelo, e seng feela kankere empa le bakeng sa lefu le lecha e sa tsejoeng. Ke ho ja lijo tse nang le GMOs, motho eo ha e le hantle infects mabifi haholo livaerase maiketsetso.

mele ea rōna e lemoha liprotheine liphatsa tsa lefutso fetotsoeng lihlahisoa lijo e le tsoang linaheng tse ling, ke hore, allergenic. Ka mohlala, e ileng ba bōptjoa le soybean liphatsa tsa lefutso Brazil linate ho ntlafatsa soya protheine. Empa batho ba 'nileng ba alejiki ho linate Brazil, leka soya ena, o ile a fumana matla alejiki itšoara joang, esita le bolaeang. Ke feela ka mor'a letoto la linyeoe kotsi, tsa soya sena ho GMO ho e se e hulwa rekisoe.

hangata haholo bakeng sa lijalo tse ncha ho sebelisa liphatsa tsa lefutso tse fokotsa nahanela ho lithibela-mafu. Ho batho e etsa hore e kholo eo e potlakileng ea libaktheria pathogenic hore na ho hanyetsa ikhethang ho lithibela-mafu leha e le efe.

Lilemong tsa morao tjena, baahi ba matjhabeng ba qala ho hlokomela boholo ba sebele ba likotsi tsa dijo liphatsa tsa lefutso fetotsoeng. Joale ba thibetsoe sale Europe, 'me bahlahisi sebelisa bona feela bakeng sa ho kenya tshebetsong le World boraro. Khang feela "bakeng sa", e leng o ile a lula ka lik'hamphani joalo - ya kotulo e khōlō le tsekedi le "liphatsa tsa lefutso le boenjiniere tla boloka lefatše ke tlala." Leha ho le joalo, polelo ena ke tšōmo, hobane bothata ba tlala e sa ile a etsa qeto ka tlhahiso ea ho eketsehileng, le kabo e loketseng ea lijo.

Kahoo e-ba ela hloko lijo tsa hao, u se ke ua timetsa 'mele oa hao boemong phatsa ea lefutso, hobane Bagerike ba boholo-holo ba ne ba tseba: ". Re - seo re ja"
