He aha ngā hua ātete pepeke kua whakarerekētia te ira ka ātete ki ngā pepeke? Ka tīmata tēnei me te kitenga o te "ira pūmua ātete pepeke". Neke atu i te 100 tau ki muri, i roto i tētahi mira i te tāone iti o Thuringia, Tiamana, i kitea e ngā kaipūtaiao tētahi huakita he mahi patu pepeke, ā, i tapaina ko Bacillus thuringiensis i muri i te tāone. Ko te take e taea ai e Bacillus thuringiensis te patu pepeke he mea kei roto he "pūmua ātete pepeke Bt" motuhake. He tino motuhake tēnei pūmua anti-pepeke Bt, ā, ka taea anake te here ki ngā "kaiwhakawhiwhi motuhake" i roto i te puku o ētahi pepeke (pērā i ngā pepeke "lepidopteran" pērā i ngā pūrerehua me ngā pūrerehua), ka puta ai ngā pepeke ki roto, ka mate. Kāore he "kaiwhakawhiwhi motuhake" o ngā pūtau puku o te tangata, o ngā kararehe me ētahi atu pepeke (ngā pepeke ehara i te "Lepidopteran") e here ana i tēnei pūmua. I muri i te urunga ki te ara nakunaku, ka taea anake te nakunaku me te whakaiti i te pūmua anti-pepeke, ā, kāore e mahi.
Nā te mea kāore he kino o te pūmua Bt anti-ngārara ki te taiao, ki te tangata me ngā kararehe, kua neke atu i te 80 tau te whakamahinga haumaru o ngā patu pepeke koiora me tōna wāhanga matua i roto i te mahi ahuwhenua. Nā te whanaketanga o te hangarau whakawhiti ira, kua whakawhitihia e ngā kaiwhakatupu ahuwhenua te ira "pūmua ātete pepeke Bt" ki ngā hua, ā, kua ātete hoki ngā hua ki ngā pepeke. Kāore e pāngia te tangata e ngā pūmua ātete pepeke e mahi ana ki ngā pepeke i muri i te urunga ki te ara nakunaku o te tangata. Mō mātou, ka nakunakuhia, ka whakaitihia hoki te pūmua ātete pepeke e te tinana tangata, pērā i te pūmua i roto i te miraka, te pūmua i roto i te poaka, me te pūmua i roto i ngā tipu. E kī ana ētahi tāngata, pērā i te tiakarete, e kiia ana he kai reka e te tangata, engari ka paitinihia e ngā kurī, ka whakamahia e ngā hua ātete pepeke kua whakarerekētia te ira ngā momo rerekētanga, koinei hoki te mauri o te pūtaiao.
