Mbewu zosinthidwa majini zomwe sizimadwala tizilombo zimapha tizilombo ngati zitadya. Kodi izi zingakhudze anthu?

N’chifukwa chiyani mbewu zosinthidwa majini zomwe sizimalimbana ndi tizilombo zimalimbana ndi tizilombo? Izi zimayamba ndi kupezeka kwa "jini la mapuloteni losagonjetsedwa ndi tizilombo". Zaka zoposa 100 zapitazo, m’mphero m’tawuni yaying’ono ya Thuringia, Germany, asayansi adapeza bakiteriya yomwe imagwira ntchito yopha tizilombo ndipo anaitcha Bacillus thuringiensis dzina la tawuniyi. Chifukwa chomwe Bacillus thuringiensis imatha kupha tizilombo ndichakuti ili ndi "puloteni yapadera ya Bt yolimbana ndi tizilombo". Puloteni iyi yotsutsana ndi tizilombo ya Bt ndi yapadera kwambiri ndipo imatha kumangirira ku "ma receptors enaake" m’matumbo a tizilombo tina (monga tizilombo ta "lepidopteran" monga njenjete ndi agulugufe), zomwe zimapangitsa kuti tizilombo tibowole ndi kufa. Maselo am’mimba a anthu, ziweto ndi tizilombo tina (tizilombo tosakhala "Lepidopteran") alibe "ma receptors enaake" omwe amamanga puloteni iyi. Pambuyo polowa m’mimba, puloteni yotsutsana ndi tizilombo imatha kungogayidwa ndikuwonongeka, ndipo sigwira ntchito.

Popeza mapuloteni oletsa tizilombo a Bt ndi osavulaza chilengedwe, anthu ndi nyama, mankhwala ophera tizilombo omwe ali nawo ngati gawo lalikulu akhala akugwiritsidwa ntchito mosamala pakupanga ulimi kwa zaka zoposa 80. Ndi chitukuko cha ukadaulo wosintha majini, obereketsa alimi asintha jini la "puloteni yolimbana ndi tizilombo ya Bt" kukhala mbewu, zomwe zimapangitsanso mbewu kukhala zosagonjetsedwa ndi tizilombo. Mapuloteni osagonjetsedwa ndi tizilombo omwe amagwira ntchito pa tizilombo sagwira ntchito pa anthu atalowa m'mimba mwa munthu. Kwa ife, mapuloteni osagonjetsedwa ndi tizilombo amagayidwa ndikuwonongeka ndi thupi la munthu monga momwe mapuloteni omwe ali mu mkaka, mapuloteni omwe ali mu nkhumba, ndi mapuloteni omwe ali mu zomera. Anthu ena amati monga chokoleti, chomwe chimaonedwa ngati chakudya chokoma ndi anthu, koma chimayikidwa poizoni ndi agalu, mbewu zosagonjetsedwa ndi tizilombo zosinthidwa majini zimapezerapo mwayi pa kusiyana kwa mitundu yotere, komwe ndi mfundo yaikulu ya sayansi.
