Abantu abasendaweni ethile bahlala befika njalo ngokuhamba kwesikhathi, njengoba kunezici ezithile ezinomkhawulo ezilawula ukukhula kwazo. Zihlukaniswe ngokujwayelekile ngamaqembu amakhulu amabili - kuncike kokuminyana kwabantu kanye nokuzimela kwabantu.
Izici zincike ekumeni kwabantu
Leli qembu lifaka imingcele ekhawulela ukukhula kwabantu ngokuya ngenani lamalungu alo. Isibonelo, ukutholakala kokudla kungaba yinto elawula ukukhula kwabantu. Uma ubukhulu be-biocenosis buphansi, imithombo yokudla elinganiselwe ingaba yanele ukusekela impilo yabantu bonke endaweni enikezwe indawo ethile. Kodwa-ke, njengoba inani lezakhamizi landa, ukutholakala kokudla kuzoba phansi futhi ibanga maduzane lizofinyelela amandla alo okuphatha. Ngakho-ke, inani lokudla liba yinto encike kokuminyana elawula ubukhulu besibalo sabantu. Inqubo yokubuyisa izakhamizi enombolweni yazo yasekuqaleni imvamisa ibizwa ngokuthi umthetho.
Ukulawulwa kwabantu endle
Izici zokuncika kokuncika kokuxinana ngokuvamile zihlotshaniswa nezinto eziphilayo eziphila nge-biotic kunokuba kube nezici ezibonakalayo zemvelo. Lokhu kufaka phakathi:
- Umncintiswano phakathi kwabakhileyo. Lapho inani labantu lifinyelela kokuxinana okuphezulu, abanye abantu bazama ukusebenzisa inani elifanayo lezinsizakusebenza, okuholela emzabalazweni wokudla, amanzi nezinye izindlela ezidingekayo ukuze usinde futhi uzalane.
- Ukudla. Amaqembu anabantu abaningi angaheha izilwane ezidla ezinye. Lapho izilwane ezidla ezinye zidla abantu abaningi, zona, ngokunciphisa lokhu, zandisa ezazo. Lokhu kudala amaphethini wokujikeleza ajwayelekile.
- Izifo nezinambuzane. Izifo ezibulalayo zivame ukukhula ngamaqembu amakhulu. Lokhu kusebenza nasekusabalaleni kwama-parasites.
Ukulawulwa kosayizi wesibalo sabantu nakho kungathatha uhlobo lwezinguquko zokuziphatha noma zomzimba kuzinto eziphilayo zabantu. Isibonelo, ulwelwesi lusabela ekuxinaneni kwabantu abaningi ngokufuduka ngamaqembu beyofuna izindawo ezintsha, ezivulekile ngokwengeziwe.
Izici ezingancikile ekumeni kwabantu
Ukuguqulwa kuyisethi yezinto ezilawula inani labantu elinganciki ebunzimeni balo. Isibonelo, umlilo wasendle ungabulala inani elikhulu lama-kangaroo, kungakhathalekile ukuthi abantu baningi kangakanani endaweni. Amathuba okufa kwezilwane awancikile kwinani lazo.
Ezinye izinto, ezizimele ngobuningi, ezilawula usayizi wabantu abahlala endaweni yabo:
- izinhlekelele zemvelo ezifana nezikhukhula, imililo, izivunguvungu;
- ukungcoliswa komoya, amanzi kanye nemvelo jikelele.
Ubuningi bezinto ezizimele abucindezeli usayizi wesibalo lapho zidlula amandla okuphatha imvelo. Zibangela ushintsho olukhulu kubantu futhi kwesinye isikhathi zingadala ukunyamalala ngokuphelele kwe-biocenosis.
Ngokungafani nezici zokulawula, izinto ezishintshayo azikwazi ukugcina usayizi wesibalo sabantu ezingeni eliqhubekayo. Imvamisa ziholela ekuguqukeni okungazelelwe nokungazinzi enanini lezakhamizi, kufaka phakathi ukubhujiswa okuphelele kwamaqembu amancane.
