Izinsiza zomhlaba ziyingcebo ebaluleke kunazo zonke emhlabeni wethu. Ngeshwa, akubona bonke abantu abakubonayo lokhu, ngakho-ke namuhla kunezinkinga eziningi ezihambisana nokungcola kwenhlabathi:
- ukungcola komhlaba onama-pesticides kanye namakhemikhali anobuthi;
- Ukungcoliswa kwenuzi;
- ukungcoliswa kwamakhemikhali;
- ukulahleka kwenzalo;
- ukuguguleka kwenhlabathi kwamanzi nomoya;
- ukugwaduleka;
- ukuqedwa nokucekelwa phansi kwezinsizakusebenza zomhlaba.
Ukuxazulula lezi zinkinga nokuvimbela ezintsha, kuyadingeka ukwenza izinyathelo zemvelo ukuvikela inhlabathi, ngoba izinsiza zomhlaba zeplanethi yethu ziyinzuzo engapheli, inani lazo elilinganiselwe.
Izizathu zokongiwa kwenhlabathi
Ukongiwa kwenhlabathi kuyinkinga yomhlaba wonke njengoba kungabangelwa yizinhlekelele zemvelo kuphela, kepha ezimweni eziningi kwenziwa yimisebenzi ye-anthropogenic. Enye yezimbangela zokucekelwa phansi kwenhlabathi ukusetshenziswa kwezindawo ezinkulu kwezolimo. Abantu basebenzisa izinsiza zomhlaba ngokungenangqondo. Ukulima kudala umonakalo omkhulu. Amasimu amakhulu alinyiwe, kusetshenziswa izinto eziyingozi, kulinywa okunamandla, izinto eziwusizo ziyagezwa zingene emhlabathini, okuholela ekusetshenzisweni kokwenza usawoti emhlabeni. Umbuso wamanzi womhlaba nokondliwa kwawo ngamanzi angaphansi komhlaba kuphazanyiswa yizinhlelo ezahlukahlukene zokunisela (imisele nezindawo zokugcina amanzi). Uma ungayiniki insimu "ukuphumula", khona-ke iphela kakhulu kangangokuba ilahlekelwa ngokuphelele ukuzala kwayo, azikho izilimo ezingakhula kuyo, futhi kungenzeka ukuthi esikhundleni sensimu, kuzovela ugwadule maduzane.
Izenzo zokongiwa kwemithombo yomhlaba
Abantu abaningi abanobuhlakani sebenesiqiniseko sokuthi umhlaba kufanele uhlonishwe futhi usetshenziswe ngendlela efanele. Ngalokhu, i-complex yokuvikelwa kwemithombo yomhlaba isakhiwe, kufaka phakathi izinyathelo zomthetho, ezomnotho, ezomnotho, ezobuchwepheshe nezinye. Zihlose ukulawula ukusetshenziswa kwenhlabathi:
- ukusetshenziswa okunengqondo;
- ukuncishiswa komhlaba wezolimo;
- ukusetshenziswa kwezindlela zokulima eziphumelelayo;
- ukwenza ngcono isimo somhlabathi;
- ukuqedwa kwemiphumela yokungcola.
Uma abantu behlanganyela ekubuyiseleni izinsiza zomhlaba, kuzosindisa iningi lezinto eziphilayo zeplanethi yethu. Ukwandisa indawo eluhlaza kubalulekile kulokhu, njengoba izihlahla zingukhiye ekuqiniseni inhlabathi. Ngakho-ke, ukulondolozwa kanye nekhwalithi yezinsiza zomhlaba zeplanethi yethu kuncike kubantu uqobo, ngakho-ke ukuvikelwa komhlaba kudlala indima ebalulekile kule nqubo.
