Kugwiritsidwa ntchito kwa zamoyo zomwe zasinthidwa ndi zotsutsa zina
Zamoyo zosinthidwa, kapena GMO , zimakhala zomera kapena zinyama zomwe DNA yasinthidwa kudzera mwa majeremusi.
Kawirikawiri, GMO imakhala ndi kachilombo kamene kamasinthidwa mwa kugawa jini kuchokera ku chomera kapena chomera china - nyama izi kapena zomera zimatchulidwa kuti "zamoyo".
Monga chitsanzo chodziŵika bwino cha zamoyo zamtunduwu, choyamba ganizirani botolo la kangaude, lopangidwa ndi kangaude.
Ofufuza a GMO anatenga geni kuti apange silika ku kangaude ndipo amaipaka mu DNA ya mbuzi.
Mbuzi imapanga mapuloteni kuti apange kangaude mu mkaka wawo wa mbuzi. Akatswiri ofufuza zamankhwala amalandira mapuloteni a silika ndipo amapanga silika wosakanizika kwambiri, omwe ali ndi mankhwala ambiri komanso mafakitale.
Koma Ndani Amafunikira GMO?
Zina mwazi, zamoyo zomwe zimasinthidwa ndi majeremusi zikungopitiriza kugwira ntchito zomwe obzala ndi zinyama akhala akuzichita kwa zaka zambiri, mwachitsanzo, kukulitsa makhalidwe monga liwiro la mpikisano kapenanso mkaka wa ng'ombe, komanso kuchotsa makhalidwe oipa monga momwe angayambitsire matenda.
Kuswana kwachikhalidwe, komabe, ndi pang'onopang'ono ndondomeko yomwe ili ndi zolakwika. Kuwonjezera pa kukhala mofulumira komanso kosavuta kukula, palibe wobereketsa angapange mtundu wa GMO wambiri monga nsomba za nsomba zomwe tatchulazi.
Kugwiritsa ntchito GMOs kwakukulu kwambiri kwakhala kulima, kuti apange zakudya zamasinthidwe.
Zomera zimasinthidwa kuti zitha kukaniza matenda, kulekerera kwa chilala, kukana kutentha kapena kutentha, kutentha kwa zakudya, komanso kukana tizilombo toyambitsa matenda. Mwa majeremusi oyambitsa tizilombo toyambitsa matenda, asayansi akuyembekeza kuchepetsa kugwiritsa ntchito mankhwala ophera tizilombo.
Ma GMO amakhalanso ndi mankhwala ogwiritsira ntchito mankhwala, komanso "phytoremediation," kugwiritsa ntchito zomera kutsuka poizoni ndi zinthu zina zoopsa kuchokera ku nthaka ndi madzi.
Mitengo ina, mwachitsanzo, yasinthidwa kuti imange zitsulo zoopsa kuchokera ku nthaka yoipitsidwa.
Koma ma GMO ena sali ovomerezeka ndi zachilengedwe: Kukaniza kwa Herbicide kungapangitse kuti azitha kupanga mavitamini, ndipo mbewu zamasamba zomwe zimalekerera mankhwala ophera tizilombo tingathe kupulumuka ngakhale pamene zomera zoyandikana - makamaka namsongole - zimapulitsidwa ndi mankhwala ophera.
Monsanto Company, mwachitsanzo, yakhazikitsa chomera cha soya chosagonjetsedwa ndi heronside Roundup ya Monsanto. Chitsanzo ichi cha ulimi wa fakitale amalola alimi kutaya masamba awo a soya ndi Roundup, kupha namsongole ndi zomera zina, ndikusiya zomera za soya.
Kodi GMOs ndi yotetezeka bwanji?
Nkhani ya chitetezo yathamangira kuzungulira GMOs popeza akatswiri ofufuza oyamba atulukira nawo m'ma 1970. Ngakhale otsutsa atsimikizira kuti mphamvu zopanda malire za GMOs zitha kulimbana ndi matenda, zimapangitsa kuti mbewu zizikhala bwino komanso kuteteza zachilengedwe, otsutsa akudandaula za kukula kwa "Frankenfoods" zomwe zingathe kufalikira kumalo ena alimi, zomwe zingakhale zovuta kwambiri zochitika zachilengedwe.
Zina mwazolakwa zazikuluzikulu ndizopangidwe za GMOs kuti zitheke kuwonjezeka kwa ma antibiotic omwe sagonjetsedwa ndi "superwegs" omwe sagwiritsidwe ntchito ndi mankhwala oopsa kwambiri ndi mankhwala owopsa.
Palinso umboni wakuti GMO zimagwiritsidwa ntchito popititsa patsogolo ntchito zogulitsa zamalonda kuwononga alimi ang'onoang'ono omwe sagwiritsa ntchito mbewu za GMO.
Gwiritsani Ntchito ndi Ulamuliro wa GMO Padziko Lonse
Chifukwa cha nkhawa zomwe zimagwirizanitsidwa ndi GMOs, European Union yakhazikitsa njira zowonongeka zogwiritsira ntchito GMO ku Ulaya, ndipo mbewu zochepa chabe za GMO zimakulira kumeneko. Europe imakhalanso ndi zolemba zoyenera, ndipo zonse zomwe zimapezeka ku GMO ziyenera kupezedwa kuti zikhale ndi zolemba zomwe zimasinthidwa.
Maiko ena monga Canada, China ndi Australia ali ndi malamulo ena ponena za kugwiritsa ntchito ndi kutchula ma GMO. Mayiko ena akupanga malamulo monga GMOs amagwiritsidwa ntchito kwambiri.
Koma ku United States, kumene magulu ambiri a GMO amapangidwa ndi kukula, malamulo okhudzana ndi chitukuko, kugwiritsa ntchito ndi kulemba ma GMO ali abwino kwambiri.
Malingana ndi mauthenga angapo mu nyuzipepala ya The New York Times , onse a FDA ndi USDA - popanikizidwa kwambiri ndi bizinesi - "sadzafuna kuti zinthu izi, kapena zakudya zomwe zili nazo, zidzatchulidwe ngati zamoyo, chifukwa Sitifuna 'kutanthauza kapena kutanthauza' kuti zakudya izi ndizosiyana. '"
Kusiyana kwa ndale ndi sayansi pa zamoyo zomwe zasinthidwa sizingathetsedwe posachedwa, ndipo kulimbikitsa ufulu wa ogula komanso chilengedwe chakumoyo chidzapitiriza kulimbana ndi magulu akuluakulu a GMO monga Monsanto, Archer Daniels Midland, Coca-Cola, DuPont, General Mills ndi makampani ena omwe ali ndi zibwenzi zambiri zachuma ku bizinesi ndi kafukufuku wamagetsi.
