Ucwaningo olusha mayelana nokuxhumana phakathi kokufa kwezinyosi kanye nezibulala-zinambuzane lusekela ukubizwa kwezindlela zokulawula izinambuzane ezihlukile. Ngokusho kocwaningo olubukezwe ontanga olwenziwe abacwaningi be-USC Dornsife olushicilelwe kumagazini i-Nature Sustainability, ama-43%.
Nakuba ubufakazi buxubile ngesimo sezinyosi ezidumile kakhulu, ezalethwa eMelika ngabakoloni baseYurophu ngekhulu le-17, ukwehla kwezinambuzane zomdabu kusobala. Cishe ingxenye yesine yezinhlobo zezinyosi zasendle “zisengozini futhi zisengozini enkulu yokuqothulwa,” ngokusho kocwaningo lwango-2017 olwenziwe yi-nonprofit Center for Biological Diversity, oluxhumanise ukulahlekelwa yindawo yokuhlala kanye nokusetshenziswa kwezibulala-zinambuzane nokushintsha kwesimo sezulu. Ushintsho kanye nokuhlala emadolobheni kubhekwa njengezinsongo ezinkulu.
Ukuze baqonde kangcono ukusebenzisana phakathi kwezibulala-zinambuzane nezinyosi zasendaweni, abacwaningi be-USC bahlaziye okubonwe okungu-178,589 kwezinhlobo zezinyosi zasendle ezingu-1,081 ezithathwe kumarekhodi omnyuziyamu, izifundo zemvelo kanye nedatha yesayensi yezenhlalo, kanye nezindawo zomphakathi kanye nezifundo zezibulala-zinambuzane ezingeni lesifunda. Endabeni yezinyosi zasendle, abacwaningi bathole ukuthi "imiphumela emibi evela ezibulala-zinambuzane isakazeke kabanzi" nokuthi ukusetshenziswa okwengeziwe kwama-neonicotinoids nama-pyrethroids, izibulala-zinambuzane ezimbili ezivamile, "kuyimbangela ebalulekile yezinguquko emiphakathini yamakhulu ezinhlobo zezinyosi zasendle."
Ucwaningo lukhomba ezinye izindlela zokulawula izinambuzane njengendlela yokuvikela izinambuzane ezithutha impova kanye nendima ebalulekile eziyidlalayo ezindaweni zemvelo nasezinhlelweni zokudla. Lezi zindlela zifaka phakathi ukusebenzisa izitha zemvelo ukunciphisa inani lezinambuzane kanye nokusebenzisa izicupho nezithiyo ngaphambi kokusebenzisa izibulala-zinambuzane.
Ezinye izifundo zisikisela ukuthi ukuncintisana ngempova yezinyosi kuyingozi ezinyosini zomdabu, kodwa ucwaningo olusha lwe-USC alutholanga ukuxhumana okuphawulekayo, kusho umbhali oholayo wocwaningo kanye noprofesa we-USC wesayensi yezinto eziphilayo kanye ne-biology yokulinganisa kanye neyokubala uLaura Laura Melissa Guzman uyavuma ukuthi kudingeka ucwaningo olwengeziwe ukusekela lokhu.
“Nakuba izibalo zethu ziyinkimbinkimbi, idatha eningi yendawo neyesikhathi ilinganiselwa,” kuvuma uGuzman esitatimendeni sabezindaba saseyunivesithi. “Sihlela ukulungisa ukuhlaziya kwethu nokugcwalisa izikhala lapho kungenzeka khona,” kwengeza abacwaningi.
Ukusetshenziswa kabanzi kwezibulala-zinambuzane nakho kuyingozi kubantu. I-Environmental Protection Agency ithole ukuthi ezinye izibulala-zinambuzane, ikakhulukazi ama-organophosphate nama-carbamates, zingathinta isimiso sezinzwa somzimba, kanti ezinye zingathinta isimiso se-endocrine. Cishe amakhilogremu ayizigidi eziyi-1 ezibulala-zinambuzane asetshenziswa minyaka yonke e-United States, ngokusho kocwaningo lwango-2017 olwenziwe yi-Ohio-Kentucky-Indiana Aquatic Science Center. Ngo-Ephreli, i-Consumer Reports ithe ithole ukuthi ama-20% emikhiqizo yase-US aqukethe izibulala-zinambuzane eziyingozi.
