Uhlangothi Olumnyama Lokukhiqizwa Kwenyama: Indlela Okubhubhisa Ngayo Indawo Yethu Ezungezile
Sanibonani, bafundi!
Sekuyisikhathi sokuthi sivule ikhethini futhi sikhanyise ngesihloko esiphikisanayo esivame ukunganakwa - uhlangothi olumnyama lokukhiqizwa kwenyama kanye nomthelela walo omubi endaweni yethu. Kusukela ekugawulweni kwamahlathi kanye nokungcoliswa kwamanzi kuya ekukhishweni kwamagesi okushisa kanye nokumelana nama-antibiotic, imiphumela yesifiso sethu esingapheli senyama isakazeke kakhulu futhi iyesabisa. Namuhla, njengengxenye yochungechunge lwethu "olukhethiwe", sihlola izindleko ezifihliwe zokukhiqizwa kwenyama futhi sihlole ukuthi ivula kanjani kancane kancane indwangu ebucayi yeplanethi yethu.
Izindleko Zemvelo Zokulima Imfuyo
Phakathi kwamasimu amakhulu kanye nezindawo ezinhle, kulele iqiniso elibi kakhulu. Ukukhiqizwa kwenyama ngobuningi kuhilela ukubhujiswa kwezindawo ezinkulu zamahlathi ukuze kuvulwe indawo yokukhiqizwa kokudla kwezilwane kanye nokudla amadlelo. Izinhlobo eziningi ziye zasuswa, izindawo zokuhlala zaphazamiseka, kanye nezindawo zemvelo zashintsha unomphela. Ukugawulwa kwamahlathi okubangelwa ukukhiqizwa kwenyama akugcini nje ngokusongela ukuhlukahluka kwezinto eziphilayo kodwa futhi kwandisa ushintsho lwesimo sezulu, njengoba izihlahla zidlala indima ebalulekile ekubambeni i-carbon dioxide (CO2).
Ngaphezu kwalokho, inani elikhulu lomhlabathi namanzi adingekayo ukusekela ukulima kwezilwane liyamangaza. Umhlaba olimekayo udliwa ukuze kutshalwe izitshalo zokudla kwezilwane, okushiya isikhala esincane sezolimo eziqhubekayo noma ezinye izinjongo ezibalulekile. Ngaphezu kwalokho, ukusetshenziswa kwamanzi ngokweqile ekukhiqizeni inyama kwandisa ukushoda kwamanzi, okuyinkinga ephuthumayo ezingxenyeni eziningi zomhlaba. Kudingeka sikhumbule ukuthi ukukhiqiza ikhilogremu elilodwa lenyama kudinga amanzi amaningi kakhulu uma kuqhathaniswa nenani elifanayo lamaprotheni asekelwe ezitshalweni.
Ngeshwa, ukubhujiswa akupheli lapha. Ubuningi obukhulu bemfucuza yezilwane ekhiqizwa imisebenzi yokulima eqinile bubangela izingozi ezinkulu zemvelo. Amadamu okungcola kanye namachibi omquba, agcwele imfucuza yezilwane engalashwanga, akhipha izinto eziyingozi kanye namagciwane enhlabathini nasemanzini azungezile. Umphumela? Imifula engcolisiwe, amanzi angaphansi komhlaba angcolisiwe, kanye nemiphumela emibi kakhulu empilweni yasemanzini.
Ukushintsha Kwesimo Sezulu kanye Nokukhishwa Kwegesi Eshisayo
Ukukhiqizwa kwenyama, okubizwa ngokuthi kungenye yezinto ezibangela ukuguquka kwesimo sezulu, akunakunganakwa lapho kuxoxwa ngezinkinga zemvelo. Imfuyo, ikakhulukazi izinkomo, inesibopho sokukhishwa okukhulu kwegesi ye-methane. Njengenye yamagesi okushisa anamandla kakhulu, i-methane ibamba ukushisa emkhathini ngendlela ephumelela kakhulu kune-carbon dioxide (CO2). Ukuzalanisa okuqinile kanye nokondla ngokweqile kwemfuyo kunegalelo emazingeni akhuphukayo e-methane, okusheshisa kakhulu ukufudumala komhlaba.
Ngaphezu kwalokho, ukuhlola umthelela wekhabhoni embonini yonke yokukhiqiza inyama kuveza isithombe esibi. Kusukela ekuhlanzweni komhlaba kuya ekuvuleni indawo yezilwane ezifuywayo, kuya ekuthuthweni nasekucutshungulweni okusebenzisa amandla amaningi, isinyathelo ngasinye ochungechungeni lokuhlinzekwa kwenyama sikhipha inani elikhulu le-CO2. Ngisho noma kucatshangelwa izici ezifana nokuqandisa, ukupakisha, kanye nokungcola kokudla, umthelela oqongelelekayo wokukhiqizwa kwenyama uyamangaza.
Ukumelana nama-antibiotic kanye nempilo yabantu
Nakuba ukubhujiswa kwendawo esihlala kuyo kuyimbangela yokukhathazeka eyanele, imiphumela yokukhiqizwa kwenyama idlulela ngale kwemvelo. Ukusetshenziswa ngokweqile kwama-antibiotic embonini kubeka engcupheni enkulu empilweni yabantu. Emzamweni wokuvimbela izifo nokukhuthaza ukukhula, ukufuya imfuyo kuncike kakhulu ekusetshenzisweni kwama-antibiotic okuvimbela. Lokhu kusetshenziswa kwama-antibiotic okwandayo ezilwaneni kuholela ekuveleni kwamagciwane amelana nama-antibiotic, okwenza kube nzima ukwelapha izifo ezilwaneni nakubantu ngempumelelo.
Ngaphezu kwalokho, imikhuba yokulima yasefektri eqinile evame embonini yenyama idala izindawo ezifanele zokuzalela izifo zezilwane ezizalwayo - izifo ezingadluliselwa kusuka ezilwaneni ziye kubantu. Izindawo eziseduze, izimo zokungahlanzeki, kanye nokucindezeleka okubhekana nezilwane zasemapulazini kwandisa ingozi yokuqubuka kwezifo. Izehlakalo ezifana nomkhuhlane wezingulube kanye nomkhuhlane wezinyoni ziyizikhumbuzo ezesabekayo zokuxhumana phakathi kwempilo yezilwane, imvelo, kanye nabantu.
Isicelo Sokwenza Ushintsho
Isikhathi soshintsho sesifikile. Kubalulekile ukuthi siqaphele izindleko ezifihliwe zokukhiqizwa kwenyama futhi siqaphele indima yethu ekuqhubekeni kwayo. Kunezinyathelo esingazithatha ukuze sibe nomthelela omuhle:
- Nciphisa ukusetshenziswa kwenyama: Ngokufaka ukudla okuningi okusekelwe ezitshalweni ekudleni kwethu, singanciphisa kakhulu isidingo senyama futhi ngaleyo ndlela sinciphise ukukhiqizwa kwayo.
- Sekela imikhuba yokulima esimeme: Ukukhetha inyama emithonjeni ebeka phambili ukusimama kwemvelo kanye nenhlalakahle yezilwane kungakhuthaza izindlela zokukhiqiza ezinomthwalo wemfanelo.
- Hlola ezinye izindlela ezisekelwe ezitshalweni: Ukukhula kwemboni yokudla kwe-vegan kanye ne-vegetarian kunikeza izinketho eziningi kulabo abafuna ukuyeka inyama.
Khumbula, isenzo esihlangene siyisihluthulelo. Ukwabelana ngolwazi, ukuzibandakanya ezingxoxweni, kanye nokulwela ushintsho kungaba nomphumela ongemuhle, okubangela ukushintshela ekukhetheni ukudla okusimeme futhi okunozwelo.
Masime sivikele imvelo yethu, ngenxa yezizukulwane ezizayo. Ngokudalula uhlangothi olumnyama lokukhiqizwa kwenyama, singavula indlela yekusasa eliqhakazile, eliluhlaza, nelinobunye.
