Kuchitira nkhanza
Pali umboni wamphamvu wosonyeza kuti nsomba zimatha kumva ululu komanso kusonyeza mantha. Pafupifupi nsomba iliyonse imene imakodwa muusodzi wamalonda imafa chifukwa cha kubanika. Nsomba zogwidwa m'madzi akuya zimavutika kwambiri: zikakhala pamtunda, kupsinjika maganizo kungayambitse kuphulika kwa ziwalo zawo zamkati.
Limodzi mwa mfundo zofunika kwambiri pankhani ya ufulu wa zinyama ndi "speciesism". Ili ndilo lingaliro lakuti anthu nthawi zambiri amawona nyama zina kukhala zosayenerera chifundo. Mwachidule, anthu amatha kumvera chisoni nyama yokongola komanso yokongola yaubweya, koma osati ndi nyama yopanda chifundo yomwe sichiwapangitsa kumva kutentha. Anthu omwe amavutika kwambiri ndi vidism ndi nkhuku ndi nsomba.
Pali zifukwa zambiri zomwe anthu amakonda kuchitira nsomba mosasamala. Chachikulu, mwina, ndikuti chifukwa nsomba zimakhala pansi pamadzi, m'malo osiyana ndi athu, sitiwona kapena kuganiza za iwo. Zinyama zozizira zokhala ndi maso agalasi, zomwe sizikudziwika bwino kwa ife, sizimayambitsa chifundo mwa anthu.
Ndipo komabe, kafukufuku wasonyeza kuti nsomba ndi zanzeru, zimatha kusonyeza chifundo ndikumva ululu. Zonsezi zidadziwika posachedwa, ndipo mpaka 2016, zomwe zidaperekedwa ku bukuli sizinasindikizidwe. , yofalitsidwa m'magazini ya Nature mu 2017, inasonyeza kuti nsomba zimadalira kuyanjana ndi anthu komanso anthu ammudzi kuti zithetse mavuto.
Kuwononga chilengedwe
Kupha nsomba, kuwonjezera pa kuzunzika kumene kumabweretsa kwa anthu okhala pansi pa madzi, kuli chiwopsezo padziko lonse lapansi panyanja zamchere. Malinga ndi bungwe la Food and Agriculture Organization la United Nations, “mitundu yoposa 70 peresenti ya nsomba za padziko lapansi zimadyeredwa mwadongosolo”. Zombo za asodzi padziko lonse lapansi zikusokoneza kusalimba kwa dziko la pansi pa madzi ndikuwononga zachilengedwe zomwe zakhalapo kuyambira kalekale.
Komanso, chinyengo ndi kulemba molakwika zafala m'makampani azakudya zam'madzi. Mmodzi wochokera ku UCLA adapeza kuti 47% ya sushi yomwe idagulidwa ku Los Angeles idalembedwa molakwika. Akuluakulu a usodzi akhala akulephera kutsata malire a kupha nsomba ndi malamulo a ufulu wachibadwidwe.
Kuweta nsomba mu ukapolo sikungatheke kuposa kutchera misampha. Nsomba zambiri zoweta zimasinthidwa chibadwa ndipo zimadyetsedwa zakudya zokhala ndi mankhwala opha tizilombo. Ndipo chifukwa cha nsomba zimene zimasungidwa m’makola a pansi pa madzi modzaza anthu, malo osungiramo nsomba nthaŵi zambiri amakhala ndi tizilombo toyambitsa matenda.
Mwa zina, ndi bwino kukumbukira chodabwitsa monga kupha nsomba - mawuwa amatanthauza nyama zapansi pamadzi zomwe zimagwera mwangozi muukonde wa usodzi, ndiyeno zimaponyedwa m'madzi kale zitafa. Bycatch yafala kwambiri pantchito ya usodzi ndipo imadya akamba, mbalame za m'nyanja ndi ma popoise. Makampani opanga shrimp amapeza ma kilogalamu 20 a kugwidwa mwangozi pa kilogalamu iliyonse ya shrimp yomwe yagwidwa.
Kuvulaza thanzi
Pamwamba pa izo, pali umboni woonekeratu kuti kudya nsomba ndi zoipa kwa thanzi.
Nsomba zimatha kudziunjikira kuchuluka kwa mercury ndi carcinogens monga PCBs (polychlorinated biphenyls). Pamene nyanja za padziko lapansi zikuipitsidwa kwambiri, kudya nsomba kumadzadza ndi matenda.
Mu January 2017, nyuzipepala ya The Telegraph inati: “Asayansi anachenjeza kuti anthu okonda nsomba zam’madzi amadya timapulasitiki ting’onoting’ono 11 chaka chilichonse.”
Popeza kuti kuwonongeka kwa pulasitiki kukungowonjezereka tsiku ndi tsiku, chiwopsezo cha kuipitsidwa kwa nsomba zam'nyanja chikuyembekezekanso kuwonjezeka.
