Iningi labantu emhlabeni lihlala emadolobheni, ngenxa yokuthi izindawo ezisemadolobheni zigcwele ngokweqile. Okwamanje, kubalulekile ukuphawula ukuthambekela okulandelayo kwabahlali basemadolobheni:
- ukuwohloka kwezimo zokuphila;
- ukukhula kwezifo;
- wehla ekukhiqizweni kwemisebenzi yabantu;
- ukunciphisa isikhathi sokuphila;
- ukungcoliswa kwemvelo;
- ukuguquka kwesimo sezulu.
Uma uhlanganisa zonke izinkinga zamadolobha esimanje, uhlu luyohlala njalo. Ake sichaze izinkinga ezibucayi kakhulu zemvelo yamadolobha.
Ukushintsha komhlaba
Njengomphumela wokufuduka emadolobheni, kunengcindezi enkulu kwi-lithosphere. Lokhu kuholela ekuguqulweni kokukhululeka, ukwakheka kwama-karst voids, nokuphazamiseka kwamachibi emifula. Ngaphezu kwalokho, kwenzeka izindawo eziwugwadule, ezingakulungeli impilo yezitshalo, izilwane nabantu.
Ukucekelwa phansi kwendalo
Ukubhujiswa okukhulu kwezimila nezilwane kwenzeka, ukwehluka kwazo kuyancipha, kuvela uhlobo lwemvelo "yasedolobheni". Inani lezindawo zemvelo nezokungcebeleka, izikhala eziluhlaza liyancipha. Umthelela omubi uqhamuka ezimotweni ezikhungathekisa imigwaqo emikhulu yasemadolobheni nasedolobheni.
Izinkinga zokuphakelwa kwamanzi
Imifula namachibi kungcoliswa ngamanzi angcolile asezimbonini nasekhaya. Konke lokhu kuholela ekwehliseni izindawo ezinamanzi, ukuphela kwezitshalo zemifula nezilwane. Yonke imithombo yamanzi eplanethi ingcolile: amanzi angaphansi komhlaba, izinhlelo zamanzi eziphakathi nezwe, uLwandle Lomhlaba jikelele. Omunye wemiphumela ukushoda kwamanzi okuphuza, okuholela ekufeni kwezinkulungwane zabantu emhlabeni.
Ukungcoliswa komoya
Lesi ngesinye sezinkinga zokuqala kwezemvelo ukutholwa isintu. Umkhathi ungcoliswe amagesi e-exhaust avela ezimotweni, ukukhishwa kwamabhizinisi ezimboni. Konke lokhu kuholela endaweni enothuli, imvula ene-asidi. Esikhathini esizayo, umoya ongcolile uba imbangela yezifo zabantu nezilwane. Njengoba kunqunywa amahlathi kakhulu, inani lezitshalo ezisebenza nge-carbon dioxide liyancipha emhlabeni.
Inkinga yemfucuza yasekhaya
Udoti ungomunye umthombo wokungcola kwenhlabathi, kwamanzi nomoya. Izinto ezahlukahlukene ziphinda zenziwe kabusha isikhathi eside. Ukubola kwezinto ezithile kuthatha iminyaka engama-200-500. Okwamanje, inqubo yokucubungula iyaqhubeka, kukhishwa izinto ezinobungozi ezibangela izifo.
Kukhona nezinye izinkinga zemvelo yamadolobha. No olufanele kancane umsindo, ukungcoliswa kwemisebe, ukugcwala ngokweqile koMhlaba, izinkinga zokusebenza kwamanethiwekhi asemadolobheni. Ukuqedwa kwalezi zinkinga kufanele kubhekwane nakho ezingeni eliphakeme, kepha abantu uqobo bangathatha izinyathelo ezincane. Isibonelo, ukulahla udoti emgqonyeni kadoti, ukonga amanzi, ukusebenzisa izitsha ezingaphinde zisebenze, ukutshala izitshalo.
