Zosintha zomwe zimasinthidwa zimapezeka pogwiritsira ntchito njira zamakono zowonetsera zamoyo kuti zikhale zogwirizana ndi zamoyo zoyambirira. Njira zamagetsi zimagwiritsidwa ntchito popanga zamoyo zabwino (zomera, zinyama, bowa ndi tizilombo toyambitsa matenda) ndi zinthu zinazake.
Mitundu yambiri ya kusintha kwa majini ndigwiritsiridwa ntchito kwa transgenes (ndiko kuti, kulengedwa kwa zamoyo zatsopano ndi majini oyenera kuchokera ku zamoyo zina, kuphatikizapo mitundu yosiyana).
Machitidwe a zamalonda a dziko amagwiritsa ntchito chizindikiritso chomwe chimalola wogula kusiyanitsa pakati pa zokolola zaulimi zomwe sizinasinthidwe kuchokera ku zakudya zomwe zasintha.
Sayansi yotsutsa "nkhani zoopsya"
Tidzakumbukira bwino: Mpaka lero palibe malingaliro ovomerezeka a sayansi, maphunziro ndi umboni wotsimikizira iwo, za vuto lililonse la zakudya zomwe zasinthidwa. Ntchito yokhayo pamutu uwu, zotsatira zake zomwe zinafalitsidwa m'nyuzipepala yayikulu, inavomerezedwa ndi bungwe lapadziko lonse la sayansi ngati kulakwa kosavuta komanso mwachindunji.
Malingaliro pa chitetezo cha zakudya zowonongeka mwa ma genetiki anagawa, makamaka chifukwa cha pseudoscientific speculation. Ngakhale kuti akatswiri a sayansi ya zamoyo akuganiza, gulu la asayansi (omwe sali akatswiri pa sayansi ya zamoyo) linanena kuti kugwiritsira ntchito zakudya zamasinthidwe sikuyenera kuloledwa. Anthu omwe sadziwa zambiri mu biology amasangalala "kufufuza" mutuwo, chifukwa cha tsankho lomwe limapangika pakati pa anthu, lomwe limagwirizana ndi nthano. Chifukwa cha malingaliro otchuka otere, omwe ndi osakayikitsa kwambiri kuchokera pakuwona kwa sayansi, zopangidwa ndi ma genetically modified zinaphatikizidwa mu "mndandanda wakuda".
Poziteteza GMOs
Bungwe la International Food and Agriculture Organization la United Nations (FAO) limapanga kuti kulengedwa kwa zamoyo zenizeni monga gawo limodzi la zamakono za sayansi zamakono. Kuwonjezera pamenepo, kusuntha mwachindunji kwa majeremusi okhumba, omwe amatsimikizira kukhalapo kwa makhalidwe abwino, ndikulingalira kukula kwa chilengedwe cha ntchito yothandiza. Zipangizo zamakono zamakono zogwiritsa ntchito mankhwala opangidwa ndi zina zotere zimapangitsa kuti aberekedwe akhale ndi mwayi wokhalitsa mitundu yatsopano ya zamoyo pakati pa mitundu yosagwirizana. Mwa njira, n'zotheka kupeputsa zamoyo zatsopano za jini zosayenera, zomwe ndi zofunika, mwachitsanzo, kwa zakudya za anthu odwala matenda a shuga.
Kugwiritsidwa ntchito kwa zomera zosatheka kumangowonjezera zokolola, komanso kumapangitsa kuti zamoyo zikhale ndi mphamvu zosiyanasiyana. Ndipo izi zikutanthauza kuti pakukula zamoyo zowonjezereka, agrochemistry (mankhwala ophera tizilombo ndi feteleza), komanso ma hormoni okula akhoza kugwiritsidwa ntchito osachepera kapena osakhala ndi zinthu zambiri zosasangalatsa.
Sitikukayikira kuti ndi kuwonjezeka kwa chiwerengero cha anthu padziko lapansi, kugwiritsa ntchito GMO ndi njira imodzi yothetsera njala.
Mkhalidwe wamakono wa zinthu ndi kugwiritsa ntchito GMOs
Mu European Union komanso m'madera ambiri a Soviet malo, mankhwala a GMO samagwiritsidwa ntchito kuti akhale chakudya (saloledwa kuti apange), monga momwe pulasitiki ikuyendera.
Momwemonso, munthu ali ndi ufulu wodziwa zomwe akugula ndikugwiritsa ntchito.
Komabe, otsutsa a GMO angadandaule : m'mayiko ambiri akulu omwe ali ndi ulimi wamakono, amakula ndikudya chakudya chamasinthidwe kwa nthawi yaitali popanda zotsatira zowonongeka komanso zovomerezeka.
Kuwonjezera apo (otsutsana ndi ma GMO, khalani osangalala), tonsefe tayamba nthawi yayitali, kuyambira m'ma 80 timalandira ma GMO kuchokera ku mankhwala.
