Impatho enonya
Kunobufakazi obuqinile bokuthi izinhlanzi zingakwazi ukuzwa ubuhlungu futhi zibonise ngisho nokwesaba. Cishe zonke izinhlanzi ezidotshwa ngenjongo yokuhwebelana ziyafa ngenxa yokungabi namoya. Izinhlanzi ezibanjwe emanzini ajulile zihlupheka nakakhulu: uma ziphezulu, ukucindezeleka kungaholela ekuqhekekeni kwezitho zabo zangaphakathi.
Omunye wemiqondo eyisisekelo emkhakheni wamalungelo ezilwane “uhlobo oluthile”. Lona umqondo wokuthi abantu bavame ukubona izilwane ezithile njengezingafanele ukuzwela. Kalula nje, abantu bangazwelana nesilwane esinoboya obuhle futhi esihle, kodwa hhayi ngesilwane esingenaluzwela esingabenzi bazizwe befudumele. Izisulu ezivame kakhulu ze-vidism yizinkukhu nezinhlanzi.
Kunezizathu eziningi zokuthi kungani abantu bevame ukuphatha izinhlanzi ngokunganaki okunjalo. Okuyinhloko, mhlawumbe, ukuthi ngenxa yokuthi izinhlanzi zihlala ngaphansi kwamanzi, endaweni ehlukile kweyethu, asivamile ukubona noma ukucabanga ngazo. Izilwane ezinama-scaly ezinegazi elibandayo ezinamehlo engilazi, ingqikithi yazo engacacile kithi, ayibangeli ububele kubantu.
Nokho, ucwaningo luye lwabonisa ukuthi izinhlanzi zihlakaniphile, ziyakwazi ukukhombisa uzwela nokuzwa ubuhlungu. Konke lokhu kwaziwa muva nje, futhi kuze kube ngu-2016, okunikezelwe kule ncwadi akuzange kushicilelwe. , eyanyatheliswa encwadini ethi Nature ngo-2017, ibonise ukuthi izinhlanzi zithembele ekusebenzelaneni komphakathi kanye nomphakathi ukuze zibhekane nezimo ezicindezelayo.
Ukulimaza imvelo
Ukudoba, ngaphezu kokuhlupheka okukubangelayo kwabahlala ngaphansi kwamanzi, kuwusongo lwembulunga yonke olwandle. NgokweNhlangano Yezokudla Nezolimo yeNhlangano Yezizwe Ezihlangene, “ngaphezu kwama-70% ezinhlobo zezinhlanzi emhlabeni zixhashazwa ngendlela ehlelekile”. Imikhumbi yokudoba emhlabeni wonke iphazamisa ibhalansi ethambile yomhlaba ongaphansi kwamanzi futhi ibhubhisa imvelo ebilokhu ikhona kusukela ezikhathini zangaphambili.
Ngaphezu kwalokho, ukukhwabanisa nokuqamba amanga kugcwele embonini yezilwane zasolwandle. Oyedwa ovela e-UCLA uthole ukuthi ama-47% e-sushi athengwe e-Los Angeles ayebhalwe ngokungeyikho. Imboni yezokudoba iye yehluleka njalo ukuhambisana nemikhawulo yokubamba kanye namazinga wamalungelo abantu.
Ukufuya izinhlanzi ekuthunjweni akusimeme njengokucupha okuthunjiwe. Izinhlanzi eziningi ezifuywayo zishintshwa izakhi zofuzo futhi zondliwa ukudla okunemithamo ephezulu yemithi elwa namagciwane. Futhi ngenxa yokuthi izinhlanzi zigcinwa ezitokisini eziminyene ngaphansi kwamanzi, amapulazi ezinhlanzi ngokuvamile agcwele amagciwane.
Phakathi kwezinye izinto, kufanelekile ukukhumbula into efana nokubanjwa okungalindelekile - leli gama lisho izilwane ezingaphansi kwamanzi eziwela emanethini okudoba ngephutha, bese ziphinde ziphonswe emanzini sezifile kakade. I-bycatch isabalele embonini yokudoba futhi idla izimfudu, izinyoni zasolwandle kanye nama-porpoise. Imboni yezimfanzi ibona kufika kumakhilogremu angu-20 we-catch by-catch ngayinye ikhilogremu yezimfanzi ezibanjiwe.
Kulimaza impilo
Ngaphezu kwalokho, kunobufakazi obucacile bokuthi ukudla izinhlanzi kuyingozi empilweni.
Izinhlanzi zingaqongelela amazinga aphezulu e-mercury nama-carcinogens njengama-PCB (i-polychlorinated biphenyls). Njengoba izilwandle zomhlaba ziya zingcoliswa, ukudla izinhlanzi kugcwele izinkinga zempilo ezengeziwe.
NgoJanuwari 2017, iphephandaba i-Telegraph: “Ososayensi baxwayisa ngokuthi abathandi bezilwane zasolwandle badla izingcezwana zepulasitiki ezingaba ngu-11 minyaka yonke.”
Uma kubhekwa iqiniso lokuthi ukungcoliswa kwepulasitiki kuyanda nsuku zonke, ubungozi bokungcoliswa kwezilwane zasolwandle kulindeleke ukuthi bukhule.
