IBrazil itholakala eNingizimu Melika futhi ithatha ingxenye enkulu yezwekazi. Kunemithombo ebalulekile yemvelo hhayi kuphela ezingeni likazwelonke, kodwa futhi nakwisilinganiso somhlaba jikelele. Lona uMfula i-Amazon, namahlathi enkabazwe anomswakama, umhlaba ocebile wezitshalo nezilwane. Ngenxa yokuthuthuka okusebenzayo komnotho, i-biosphere yaseBrazil isongelwa yizinkinga ezahlukahlukene zemvelo.
Ukuqedwa kwamahlathi
Iningi lezwe lihlala emahlathini ahlala eluhlaza. Izinhlobo ezingaphezu kweziyizinkulungwane ezine zezihlahla zikhula lapha, futhi zingamaphaphu eplanethi. Ngeshwa, kugawulwa izingodo ngenkuthalo ezweni, okuholela ekubhujisweni kwemvelo yehlathi kanye nenhlekelele yemvelo. Inani labantu bezinye izinhlobo zaqala ukwehla kakhulu. Izihlahla zigawulwa hhayi kuphela ngabalimi abancane, kepha futhi yizinkampani ezinkulu ezihambisa izinkuni emazweni ahlukahlukene omhlaba.
Imiphumela yokuqedwa kwamahlathi eBrazil imi kanje:
- ukwehla kwezinhlobonhlobo zezinto eziphilayo;
- ukufuduka kwezilwane nezinyoni;
- ukuvela kwababaleki kwezemvelo;
- ukuguguleka komoya kwenhlabathi nokuwohloka kwawo;
- ukuguquka kwesimo sezulu;
- ukungcoliswa komoya (ngenxa yokushoda kwezitshalo ezenza i-photosynthesis).
Inkinga yokwenziwa ugwadule komhlaba
Inkinga yesibili ebaluleke kakhulu yemvelo eBrazil ukugwaduleka. Ezindaweni ezomile, uhlaza luyancipha futhi nezimo zenhlabathi ziya ngokuya ziba zimbi. Kulesi simo, kwenzeka inqubo yokwenziwa ihlane, ngenxa yalokho okungavela i-semi-desert noma i-desert. Le nkinga ijwayelekile ezifundeni ezisenyakatho-mpumalanga yezwe, lapho inani lezimila lehla kakhulu, futhi izindawo cishe azigezwa yimizimba yamanzi.
Ezindaweni lapho ezolimo zithuthuka khona ngamandla, ukuguguleka kwenhlabathi nokuguguleka kwenhlabathi, ukungcoliswa kwezibulala-zinambuzane kanye nodaka kwenzeka. Ngaphezu kwalokho, ukwanda kwenani lemfuyo ensimini yamapulazi kuholela ekwehleni kwenani lezilwane zasendle.
Ukungcoliswa kwemvelo
Inkinga yokungcola kwe-biosphere iyaphuthuma eBrazil, nakwamanye amazwe eplanethi. Ukungcoliswa okukhulu kwenzeka:
- ama-hydrospheres;
- umkhathi;
- lithosphere.
Akuzona zonke izinkinga zemvelo zaseBrazil ezibalwe, kepha okuyinhloko kukhonjisiwe. Ukugcina imvelo, kuyadingeka ukunciphisa umthelela wemisebenzi yabantu emvelweni, ukunciphisa inani lezinto ezingcolisayo nokwenza izenzo zemvelo.
