Izilwane eziningi eziphilayo zidla ezinye izinto eziphilayo futhi ziyadliwa ngokwazo. Lokhu kubizwa ngokuthi iketango lokudla. Ngokwesibonelo, kunezinkalankala ezincane ezidla ulwelwe. Izinhlanzi zidla izinkalankala ezincane, izindwandwe zidla izinhlanzi kanti izimpisi zidla izindwandwe. Konke kulenga ndawonye njengamaparele eketango. Yingakho libuye libizwe ngokuthi wuchungechunge lokudla.
Uchungechunge lokudla yigama elivela kubhayoloji. Lena isayensi yokuphila. Zonke izidalwa eziphilayo zidinga amandla nezinsimbi zokwakha ukuze ziphile. Izitshalo zithola la mandla ekukhanyeni kwelanga. Zithola izakhi zokukhula emhlabathini ngokusebenzisa izimpande zazo.
Izilwane azikwazi ukwenza lokho. Ngakho-ke, amandla azo athola kwezinye izidalwa eziphilayo, eziwadlayo futhi azigaye. Lokhu kungaba izitshalo noma ezinye izilwane. Ngakho iketango lokudla lisho ukuthi: amandla kanye nezakhi zokwakha zisuka kolunye uhlobo ziye kolunye.
Lolu ketango aluqhubeki njalo. Kwesinye isikhathi uhlobo oluthile lungaphansi kweketango lokudla. Ngokwesibonelo, umuntu udla zonke izinhlobo zezilwane nezitshalo. Kodwa asikho isilwane esidla abantu. Ngaphezu kwalokho, abantu manje sebengakwazi ukusebenzisa izikhali ukuze bazivikele ekuhlaselweni kwezilwane.
Kwenzekani ekupheleni kochungechunge lokudla?
Kodwa-ke, iqiniso lokuthi abantu basekupheleni kochungechunge lokudla liphinde libangele izinkinga kubo: isitshalo singamunca ushevu, isibonelo, insimbi enzima njenge-mercury. Inhlanzi encane idla lesi sitshalo. Inhlanzi enkulu idla inhlanzi encane. I-heavy metal ihlezi ihamba nawe. Ekugcineni, indoda ethile ibamba izinhlanzi ezinkulu bese idla zonke izinsimbi ezisindayo ezinqwabelene enhlanzini. Ngakho-ke angakwazi ukuzifaka ushevu ngokuhamba kwesikhathi.
Ngokuyisisekelo, uchungechunge lokudla alupheli nhlobo, ngoba abantu bayafa. Ngemva kokufa kwabo, bavame ukugqitshwa emhlabathini. Lapho zidliwa izilwane ezincane njengezikelemu. Amaketanga okudla empeleni enza imibuthano.
Kungani umbono weketango ungafaneleki ngokuphelele?
Izitshalo noma izilwane eziningi azigcini nje ngokudla olunye uhlobo. Abanye baze babizwe ngokuthi ama-omnivores: badla izilwane ezihlukene, kodwa futhi nezitshalo. Isibonelo amagundane. Ngokuphambene, utshani, isibonelo, abudliwa uhlobo olulodwa lwesilwane. Umuntu kufanele akhulume okungenani ngamaketanga amaningana.
Ngakho-ke, ngezinye izikhathi umuntu ucabanga ngazo zonke izilwane nezitshalo ezihlala ehlathini elithile, olwandle, noma emhlabeni wonke. Lokhu kubizwa nangokuthi i-ecosystem. Umuntu uvame ukukhuluma ngewebhu yokudla. Izitshalo nezilwane zingamafindo kuwebhu. Zixhunywe zodwa ngokudla nokudliwa.
Esinye isithombe umbhoshongo wokudla: Umuntu, kuthiwa, ungaphezulu kombhoshongo wokudla. Phansi, kunezitshalo eziningi nezilwane ezincane, kanti phakathi nezilwane ezinkulu. Iphiramidi ibanzi ngezansi futhi incipha phezulu. Ngakho ngezansi kunezidalwa eziningi eziphilayo. Uma ufika phezulu, kuba mbalwa.
