Yonke indawo yomoya phezu kweplanethi, kusukela ezifundeni ezisenyakatho kuya ezindaweni ezishisayo, kusukela ogwini lolwandle kuya ezintabeni ezinamadwala, kuhlala izinyoni. Lolu hlobo lomhlaba wezilwane lunezinhlobo ezingaphezu kwezingu-9000, ezinendawo yazo yokuhlala, lapho izimo zilungele kakhulu uhlobo olulodwa noma olunye lwezinyoni.
Ngakho-ke, emahlathini aminyene asezindaweni ezishisayo zeplanethi kunenani elikhulu kakhulu lezinhlobo ezidinga isimo sezulu esifudumele nezinsizakusebenza zokudla eziqhubekayo. Azikho izinkathi ezibandayo lapha, izinga lokushisa eliphakeme eliqhubekayo linomthelela ekuziphatheni okuhle kwezinyoni nokuzalanisa kahle inzalo.
Izindawo zokuhlala eziyinhloko zezinyoni
Emakhulwini amaningi eminyaka edlule, izwekazi laseYurophu lalimbozwe ngamahlathi amakhulu. Lokhu kube nomthelela ekusakazekeni kwezinhlobo zezinyoni zasehlathini ezibusa iYurophu namuhla. Eziningi zazo ziyizifuduko, zifuduka ngenkathi ebandayo yasebusika ziye ezindaweni ezishisayo nasendaweni eshisayo. Ngokuphawulekayo, izinyoni ezifudukayo zihlala zibuyela ezweni lakubo, zihlela izidleke futhi zizalele izingane ekhaya kuphela. Ubude bomzila wokufuduka buya ngezidingo zemvelo zohlobo oluthile. Isibonelo, amahansi ezinyoni zasemanzini, ama-swans, amadada awasoze amisa indlela yawo aze afinyelele emikhawulweni yokubanda kwemizimba yamanzi.
Izingongolo zomhlaba kanye nezingwadule kuthathwa njengezindawo ezingezinhle kakhulu zezinyoni: izinyoni kuphela ezingasinda lapha, indlela yazo yokuphila nokudla okunomsoco onganikeza ukuzala kwezingane eziguqulelwe ezimweni zezulu ezinzima.
Ithonya lomsebenzi womnotho womuntu ezindaweni zezinyoni
Ngokwezibalo zodokotela bezinyoni, kule minyaka engamakhulu amabili edlule, cishe izinhlobo ezingama-90 zezinyoni zanyamalala eMhlabeni, inani lezinye zehlile laya eshumini futhi zisengcupheni yokuqothulwa. Lokhu kwenziwa lula:
- ukuzingela okungalawulwa nokubanjwa kwezinyoni ezithengiswayo;
- ukulima umhlaba wezintombi;
- ukugawulwa kwamahlathi;
- amanzi amaxhaphozi;
- ukungcoliswa kwemizimba yamanzi evulekile ngemikhiqizo kawoyela kanye nodoti wezimboni;
- ukukhula kwama-megalopolises;
- ukwanda kokuhamba emoyeni.
Ngokwephula ubuqotho bemvelo yendawo ngokuhlasela kwayo, impucuko, ngqo noma ngokungaqondile, iholela ekunyamalaleni okuyingxenye noma okuphelele kwale ngxenye yomhlaba wezilwane. Lokhu-ke kuholela emiphumeleni engalungiseki - ukuqubuka kwesikhonyane, ukwanda kwenani lomiyane be-malaria, njalonjalo ku-ad infinitum.
