Funda ukuthi kungani amahlengethwa asengozini yokushabalala. Ungayeki ukuyifunda!
Amahlengethwa
Amahlengethwa ayizilwane ezincelisayo zasemanzini, athathwa njengezinhlobo ezihlakaniphe kakhulu njengoba anesimiso sezinzwa esithuthuke kakhulu esiwavumela ukuba asheshise futhi abe nenkumbulo enhle.

Kungani amahlengethwa esengozini yokushabalala?
Njengamanje, amahlengethwa aye ahlupheka kakhulu eminyakeni yamuva, aze ashiya nezinhlobo zezilwane zishabalala ngokusemthethweni kanti amanye asengozini yokushabalala noma esengozini. Namuhla kunezinhlobo ezingu-41 ezihlukene zamahlengethwa, ngayinye inesimo esihlukile sesibalo sabantu, kodwa iqiniso liwukuthi izinhlobo ezihlukahlukene zashabalala, okushiya ezinye zilandela uma lokhu kunganqamuki.
Izimbangela
Izimbangela zihlukene, kodwa singafingqa ukuthi iningi lazo lidalwa wukuziphatha komuntu, okubuhlungu ukuthi izimbangela zokushabalala kwazo kungenxa yezenzo ezenziwa abantu okungaba ezentengiselwano, izimboni noma kwesinye isikhathi ungasho ukuthi sekuyingxenye yokuphila kwethu ukwenza izenzo ezilimaza ukuphila kwezinye izinhlobo zezilwane ngaphandle kokwazi, ngakho sizochaza ngokuningiliziwe izimbangela zokuqothulwa okungenzeka kwamahlengethwa amaningana.
Ukungcola
Amahlengethwa ahlushwa izinhlobo ezahlukene zokungcola njengamakhemikhali noma i-acoustic. Ukungcoliswa kwamakhemikhali ikakhulukazi kusekelwe kuzo zonke lezo zingxenye ezivela ekukhiqizeni imikhiqizo yizimboni, eziningi zalezi zimboni ziseduze nolwandle futhi zithatha leli thuba lokususa imfucuza ngokuyiphonsa olwandle ibangele amahlengethwa kanye nezinye izilwane zasemanzini. babe nezinkinga zempilo ezingathi sína.
Uwoyela nawo uyingxenye yokungcola ngenxa yezimboni kanye nokusetshenziswa kwabantu, ngakho-ke amahlengethwa angangcoliswa ngenxa yobuthi bokudla kwawo njengoba esesikhundleni sokudla njengezilwane ezidla ezinye ezinkulu, ngakho-ke ngokungcolisa amanzi Singcolisa nokudla kwawo, okuholela ekubeni amahlengethwa adakwe futhi, ezimweni eziningi, aqede ukuphila kwawo.
Ukungcola kungahluka futhi kungase futhi kube i-acoustic, into mhlawumbe abantu abaningi abangayazi, kodwa iqiniso liwukuthi umsindo udlala indima enkulu uma kuziwa ekuqothulweni kwamahlengethwa.

Ukungcoliswa kungabuye kusetshenziswe izakhi ezishiywe emanzini ezingaba kokubili ngengozi futhi ngesikhathi esifanayo kungenzeki, okungadala ukulimala okubi kakhulu kulezi zilwane ezincelisayo zasemanzini, isibonelo salokhu kungaba ukuthi zibhajwa amanetha okudoba ezitholakala ziphonswe olwandle, zingashaywa ngisho nezinhlobo ezahlukene zezinto ezisindayo ezingase zibangele nokufa kwazo okungenzeka.
Ukuzingela kwamahlengethwa kanye nokuthwebula
Amahlengethwa kwabaningi athathwa njengezilwane ezingcwele, kodwa kwabanye sekuyiyona ndlela engcono kakhulu yokuthola imali futhi amathuba amabili akhona okwenza lokho wukuzingela ukuze ahwebe noma ukuwathumba ukuze anikele ekuzijabuliseni kwabantu njengokuba se-aquarium.
Nakuba kuye kwasungulwa imithetho enakekela inhlalakahle yamahlengethwa, okwamanje maningi amazwe asaqhubeka nemikhuba elimaza inani labantu bawo, ibhizinisi elisasebenza kakhulu kwamanye amazwe ase-Asia elokuhweba ngenyama. nakuba kungekho emthethweni, abantu abaningi basaqhubeka nokukubona njengebhizinisi elingase libe khona, yingakho ukuzingela ngale njongo kuyize futhi akupheli.
Ukuhwebelana kwenyama yayo ukuze kulungiswe izitsha zokudla okumnandi kuvele kuphambana ngoba sekubonisiwe ukuthi inyama yehlengethwa ayifanele ukudliwa abantu, nokho amazwe amaningi asaqhubeka nokuba ngabathengi abakhulu benyama yamahlengethwa. ukushabalala kwalo mkhuba akubikezelwa, njengoba iJapane ingomunye wabagqugquzeli abakhulu bokuthengwa kwamahlengethwa.
Amanye amahlengethwa abanjwa ukuze akwazi ukukhonza ekuzijabuliseni kwabantu njengengxenye yemisebenzi yomkhaya, kodwa iqiniso liwukuthi ekubanjweni kwamaningi awo izinto ngokuvamile azihambi kahle, lapho ebanjwa ngenethi yokudoba amaningi awo agcina efile. ebhajwe ebangela ukulimala okukhulu ngokomzimba kubo, ngokudabukisayo kokuningi kwalokhu kubanjwa amahlengethwa agcine efile ngakho ayalahlwa futhi amanye afunwa ukuthwebula amanye angase agijime nesiphetho esifanayo.
Amanye amahlengethwa athunjwa ephila, kepha impilo yawo izoba kusukela ngaleso sikhathi ekuthunjweni njengoba amahlengethwa ayizilwane ezidumile phakathi kwabantu ngenxa ye-charisma yawo enkulu nobuntu, kodwa konke lokhu kungenxa yokuthi sekujwayelekile ukuthi amahlengethwa atholakale emanzini ahlala ekuthunjweni okuphelele. , ukufinyelela ukucindezeleka kwawo njengoba kuye kwabangelwa ushintsho oluphelele ekuphileni kwawo okuvamile, amahlengethwa ayizilwane ezijabulela inkululeko esimweni sawo sasendle, ngakho lezi zinhlobo zezinguquko zingabashaqisa kakhulu.
Izinguquko Zemvelo
Indawo yokuhlala amahlengethwa isishintshe kakhulu njengezinhlobo eziningi zezilwane, amahlengethwa abhekane nezinguquko eziningi zesimo sezulu kanye nokushoda kokudla ngenxa yokunyamalala nokungcoliswa kwezisulu zawo, ukudla okuncane okutholakalayo kunzima ukukuthola ngenxa yokuncintisana nezinye izilwane ezidla ezinye njengemikhomo. noma oshaka abaningi babulawa indlala, uma bethola ukudla bathola lokho okudingekayo ukuze baphile.
Leli phuzu ligxile kakhulu kwelokuqala ngoba ukufudumala kwembulunga yonke, ukushintsha kwesimo sezulu kanye nokushoda kokudla kungenxa yethonya labantu ngokulungisa nokusebenzisa imithombo yomhlaba ngendlela enkulu, okuholela ekungalinganini kwe-ecosystem, okuthintekayo kakhulu ezinye izidalwa eziphilayo ezihlala ezweni nolwandle, kulokhu omunye amahlengethwa, njengoba siye modified endaweni yayo, okwenza kube indawo enzima, okunzima kakhulu ukuhlala kuyo, okubangela njengomphumela umnikelo ekuqothulweni kwalesi silwane. .
Isizathu ngasinye esiye sashiwo sishiye uphawu olukhulu ekuqothulweni kwamahlengethwa, abe yizingqinamba ezinzima kakhulu kubantu bamahlengethwa aqhubeka nokwehla ngenani labantu, ngakho-ke sizokhuluma ngezinhlobo ezithile zezilwane ezibizwa ngokudabukisayo. ingozi yokushabalala.
Amahlengethwa Asengozini
Amaningi ala mahlengethwa aye abhekana nokuncipha okukhulu kwenani labantu, izimbangela zihlukene phakathi kwazo zonke, iningi linemithetho enomthelela ekuvikeleni izinhlobo zawo, kodwa izinguquko ezenziwe ngeshwa kwabaningi azizange ziphumelele ngendlela ebezifisa ngayo. ngakho sizokhuluma kancane mayelana ngamunye wabo.
