Ulwandle luhlanganisa ngaphezulu kwama-70% omhlaba futhi luyikhaya lokuhlekisa ngempilo yasemanzini. Eminyakeni yamuva nje, isidingo sokudla kwasolwandle siholele ekukhuphukeni kwamapulazi olwandle namapulazi ezinhlanzi njengendlela yokudoba okuqhubekayo. Lawa mapulazi, abizwa nangokuthi ama-aquaculture, ajwayele ukubonwa njengesixazululo sokudoba ngokweqile nendlela yokuhlangabezana nesidingo esikhulayo sokudla kwasolwandle. Kodwa-ke, ngaphansi kobuso kukhona iqiniso elimnyama lomthelela lawa mapulazi anawo endalini yemvelo yasemanzini. Ngenkathi zingabonakala njengesixazululo ebusweni, iqiniso ukuthi amapulazi olwandle nama-fish angaba nemiphumela emibi emvelweni nasezilwaneni ezibiza ulwandle ekhaya. Kulesi sihloko, sizokwehla ngokujulile emhlabeni wolwandle kanye nokulima izinhlanzi futhi siveze imiphumela efihliwe esisongela imvelo yethu engaphansi kwamanzi. Ukusuka ekusetshenzisweni kwama-antibiotic nama-pesticides ku ...
Ukulahleka Kwezinto Ezihlukahlukene
Ukulima efektri, indlela ethuthukile nenqwaba yokukhulisa izilwane ukukhiqizwa kokudla, sekuyinto ebalulekile yemvelo. Inqubo yezilwane ezikhiqiza ngobuningi zokudla ayikhuphuki kuphela imibuzo yokuziphatha ngenhlalonhle yezilwane kodwa futhi inomthelela omubi emhlabeni. Nawa amaqiniso ayi-11 abalulekile mayelana namapulazi efektri kanye nemiphumela yawo yezemvelo: Amapulazi awo angu-1- abamba amanzi aphuma efektri angomunye wabahlinzeki abaholayo ekuphumeni kwamagesi abamba ukushisa abamba ukushisa, ekhulula amanani amakhulu we-methane ne-nitrous oxide emkhathini. Lawa magesi anamandla amakhulu kune-carbon dioxide endimeni yawo ekushiseni komhlaba, nge-methane eneminyaka engaba ngu-28 ephumelela kakhudlwana ekushiseni ukushisa kweminyaka engu-100, futhi i-nitrous oxide cishe ama-298 amahlandla angama-298. Umthombo oyinhloko wokukhishwa kwe-methane epulazini efektri uvela ezilwaneni ezihlubukayo, njengezinkomo, izimvu nezimbuzi, ezikhiqiza inqwaba ye-methane ngesikhathi sokugaya ...
Yize ukuzingela kwakuyingxenye ebalulekile yokusinda komuntu, ikakhulukazi eminyakeni eyi-100,000 edlule lapho abantu bokuqala bethembele ekuzingeleni ukudla, indima yayo namuhla ihluke kakhulu. Emphakathini wanamuhla, ukuzingela kuye kwaba umsebenzi wokuzilibazisa onobudlova kunokuba kube nesidingo sokuthola ukondla. Ukuze iningi labazingeli, akuseyona indlela yokusinda kepha uhlobo lokuzijabulisa oluvame ukubandakanya ukulimala okungadingekile ezilwaneni. Izisusa ezingemva kwesimanje ukuzingela ngokuvamile ziqhutshwa injabulo yomuntu siqu, ukuphishekela izindondo, noma isifiso sokubamba iqhaza esikweni elidala iminyaka yobudala, esikhundleni sokudla. Eqinisweni, ukuzingela kuye kwaba nemiphumela emibi kubantu bezilwane emhlabeni wonke. Kube nomthelela omkhulu ekuqothulweni kwezinhlobo ezahlukahlukene, ngezibonelo eziphawuleka kakhulu kufaka phakathi ihlosi laseTasmanian kanye ne-AUK enkulu, abantu bakaBantu ababenqunyelwe yimikhuba yokuzingela. Lokhu kuqothuka okubuhlungu kuzikhumbuzo ezimnandi ze ...
Ukulima efektri, noma ezolimo zezimboni, kumi e-Crossroads yokukhiqizwa kokudla komhlaba kanye nokuwohloka kwemvelo. Ngenkathi ihlangabezana nesidingo esikhulayo semikhiqizo yezilwane enokusebenza okuphezulu, ukukhokha kwayo kwemvelo kuyamangaza. Ukusuka ekuqothulweni kwamahlathi okugcwele kanye nokungcoliswa kwamanzi ekuphumeni kwamagesi abamba ukushisa kanye nokulahleka kwe-bioriversity, ukulima efektri kungumshayeli oholayo wokulimala kwemvelo. Le ndatshana idlulela emaqinisweni abucayi kanye nezibalo ngemuva komthelela wayo, igqamisa isidingo esiphuthumayo sezenzo zokulima ezizinzile futhi yaziswa izinketho zabathengi ukuvikela ikusasa lomhlaba wethu
Ezolimo Zezilwane zimi njengomshayeli oholayo wokucekelwa phansi kwezemvelo, ekhuthaza ukugawulwa kwamahlathi nokusheshisa ukulahleka kwezinhlobonhlobo zezinto eziphilayo ngezinga elingakaze libonwe. Isifiso senyama yenyama, ubisi, kanye neminye imikhiqizo ethathwe yezilwane ifuna amapheshana aphezulu omhlaba wokudla kwemfuyo kanye nokondla ukukhiqizwa, kaningi ngezindleko zamahlathi angafinyeleleki kanye nemvelo. Lokhu kunwetshwa okungapheli akukupheli izinhlobo zezinto ezingenakubalwa kepha futhi kukhipha amanani amakhulu amagesi abamba ukushisa, ukuqinisa ukuguquguquka kwesimo sezulu. Ukusuka ekubhujisweni kwendawo yokuhlala ekungcoleni kwamanzi kanye nokunyuka kwezilimo ze-monoculture zokudla kwezilwane, imiphumela ye-ripple ifinyelela kude. Kulesi sihloko, siyaphila ngendlela ezolimo zezilwane ziphinda zisebenzisa kabusha izimo zomhlaba weplanethi yethu futhi zisongele ukulinganisela kwalo kwemvelo ngenkathi zihlola izixazululo ezizinzile ezingasiza ukunciphisa le miphumela
Njengoba ushintsho olubhekise ekudleni okususelwa kwizitshalo luzuza umfutho, kuphakama imibuzo ngekusasa lezilwane ezilimazwe emhlabeni ngaphandle kokudla kwenyama. Kungenzeka yini ukuthi lezi zinhlobo ezikhethiwe, zenzelwe umkhiqizo wezolimo, ukuqothulwa kobuso? Le nkinga evuselelwa umcabango idelela ubunzima obuzungezile izinhlobo zokuhweba ezizungeze ukuthengisa kanye nokusinda kwazo ngaphandle kwezinhlelo zokulima izimboni. Ngaphandle kokukhathazeka kokuqothulwa, kugcizelela izinzuzo zemvelo zokuguqula imvelo kanye nezinzuzo zokuziphatha zokunciphisa ukuphuma kwezolimo - ukusika amagesi abamba ukushisa, ukubuyisela i-ecosystems, kanye nokubeka phambili inhlalonhle yezilwane. Ukudlulela ku-veganism akunikezeli nje ushintsho lokudla kepha ithuba lokuphinda uxhumeke ubuntu nemvelo futhi ubeke amandla ikusasa elizinzile kubo bonke abantu abaphilayo
Izilwandlekazi, zigcwele impilo futhi zibalulekile ekulinganiseni kweplanethi yethu, zivinjezelwa ekushisweni ngokweqile nangamandla abhubhisayo - amabutho amabili abhubhisayo ashayela izinhlobo zasolwandle ekuweni. Ukudoba ngokweqile kuchithe izinhlanzi zabantu ngamanani angenakuvikeleke, ngenkathi u-bycatch ngokungabonakali izicupho ezibuthakathaka njengefudu lwasolwandle, amahlengethwa kanye nezinyoni zasolwandle. Le mikhuba ayiphazamisi kuphela i-Marine Ecosystems yaseManzini kodwa futhi isongela imiphakathi yasogwini okuncike ekujuleni kwezimpilo zokuziphilisa. Lo mbhalo uhlola umthelela omkhulu wale misebenzi ezinhlanganweni zezinto eziphilayo kanye nemiphakathi yabantu ngokufanayo, ebiza isinyathelo esiphuthumayo ngokusebenzisa izindlela zokuphatha zomhlaba kanye nokubambisana komhlaba wonke ukuvikela impilo yolwandle lwethu
Inyama kade yaba yinto ende yokudla emhlabeni wonke, kepha umthelela wayo wezemvelo ukukhulisa ukukhathazeka okukhulu. Ukusuka ekuqothulweni kwamahlathi kanye nokushoda kwamanzi ekuphumeni kwamagesi abamba ukushisa kanye nokulahleka kwezinhlobonhlobo zezinto eziphilayo, imboni yenyama icindezela izinsiza zeplanethi ngezinga elethusayo. Njengoba ukufunwa kuqhubeka ukukhula, le mikhuba ishayela ukuguquguquka kwesimo sezulu kanye nomonakalo wemvelo ngezinga lomhlaba wonke. Lo mbhalo uhlola ukulandelelwa kwemvelo kokukhiqizwa kwemvelo okuqokomisa ukukhiqizwa kwemvelo njengokubhujiswa kwendawo, ukungcoliswa kwezinyawo, kanye nokubheka ezinye izindlela ezimeme ezihambisana nazo zombili izinhloso zezempilo kanye nokulondolozwa kwemvelo
Ezolimo Zezilwane, ezihlangene ezimpilweni zabantu, manje sekungumshayeli oholayo wokuwohloka kwemvelo nezinhlobo zezilwane. Njengokudla kwenyama yenyama, ubisi, kanye neminye imikhiqizo yezilwane kukhula, umthelela wemboni embonini yezinto eziphilayo ufinyelele amazinga abucayi. Ukusuka ekuqothulweni kwamahlathi kodlama amadlelo futhi okuphakelayo izitshalo ekungcoleni kusuka emikhubeni ebanzi yokulima, ezolimo zezilwane ziguqula kabusha imvelo kanye nokucindezela kwezinhlobo eziningi ekuqothulweni. Lo mbhalo uhlola imiphumela efinyelela kude yokukhiqizwa kwemfuyo ezindaweni zokuhlala, impilo yasolwandle, i-pollinators, kanye nemithombo yezemvelo ngenkathi kugqamisa izixazululo ezizinzile ezingasiza ukuncipha kwezinhlobonhlobo zezinto eziphilayo
Isifiso sokukhuphuka somhlaba wonke semikhiqizo yezilwane siye saqhutshwa ukwamukelwa okusabalele kwezolimo efektri, uhlelo luncike kakhulu ekukhiqizeni okuphakelayo kwezimboni. Ngaphansi kwe-veneer yayo yokusebenza kahle kulele ukukhishwa kwemali okuthe xaxa, ukulahlekelwa yi-biodiversity, kanye nokungcola kwamanzi, kanye nokungcola kwamanzi kungenye nje yemithelela ebhubhisayo eboshelwe ukulima izilimo ze-monoculture njenge-soy kanye nommbila wokudla kwezilwane. Le mikhuba iqeda izinsiza zemvelo, i-erode yezempilo yenhlabathi, iphazamise imvelo, kanye nemithwalo yendawo ngenkathi kuqinisa ukuguquguquka kwesimo sezulu. Lo mbhalo uhlola izindleko zemvelo zokukhiqizwa okuphakelayo kwezilwane zasemafulemini zasefekthri futhi zigqamisa ukucindezela kudingeka ukwamukela izixazululo ezizinzile ezivikela iplanethi yethu futhi kuthuthukise izindlela zozolimo zokulima
