Umphakathi wanamuhla uxhunyaniswe ngokungenakuhlukaniswa nemvelo yomhlaba wonke, maqondana nokuthi umuntu angasho kanjani ukuba khona kwezinkinga zemvelo yezenhlalo. Phakathi kwabo, okuhambisana kakhulu yilokhu okulandelayo:
- ukuqhuma kwabantu;
- ushintsho echibini lezakhi zofuzo;
- ukugcwala kweplanethi;
- ukushoda kwamanzi okuphuza nokudla;
- ukonakala kwendlela yokuphila yabantu;
- ukufuduka emadolobheni;
- ukwanda kwemikhuba emibi kanye nezifo zabantu.
Izinkinga eziningi zemvelo zidalwa ngabantu. Ake sikhulume ngezinkinga ezithile zenhlalo nezemvelo ngokuningiliziwe.
Ukukhula ebuntwini
Njalo ngonyaka, iplanethi iyanda kubantu, okuholela "ekuqhumeni kwabantu". Ngokusho kochwepheshe, ukwanda okukhulu kakhulu kwabantu kwenzeka emazweni asathuthuka. Isibalo sabantu abakubo singu-3/4 senani lesintu sisonke, futhi bathola kuphela i-1/3 yenani lomhlaba wonke ngokudla. Konke lokhu kuholela ekwandeni kwezinkinga zemvelo nezenhlalo. Njengoba kungekho ukudla okwanele kwamanye amazwe, cishe abantu abayizinkulungwane eziyi-12 babulawa yindlala minyaka yonke minyaka yonke. Ezinye izinkinga ezivele ngenxa yokwanda kwabantu wukuhlala emadolobheni nokwanda kokusetshenziswa kwabantu.
Inkinga yezinsizakusebenza
Emkhakheni wezinkinga zenhlalo yezemvelo, kunenkinga yokudla. Ochwepheshe babecabanga ukuthi okujwayelekile ngomuntu ngamunye kungu-1 ton okusanhlamvu ngonyaka, futhi inani elinjalo lizosiza ukuxazulula inkinga yendlala. Kodwa-ke, okwamanje kuvunwa amathani ezitshalo okusanhlamvu angaphezulu kancane kwezigidi eziyizinkulungwane eziyi-1.5. Inkinga yokushoda kokudla yabonakala kuphela lapho kwaba nokwanda okukhulu kwabantu.
Ukuntuleka kokudla akuyona inkinga yodwa enkingeni yemithombo. Ukushoda kwamanzi okuphuza kuyinkinga enkulu. Inani elikhulu labantu libulawa ukungabi namanzi minyaka yonke. Ngaphezu kwalokho, kunokushoda kwezinsizakusebenza zamandla ezidingekayo embonini, ukunakekelwa kwezakhiwo zokuhlala, kanye nezikhungo zomphakathi.
Ushintsho lwechibi le-Gene
Imithelela emibi emvelweni ithinta izinguquko echibini lofuzo emhlabeni wonke. Ngaphansi kwethonya lezici zomzimba nezamakhemikhali, ukuguquka kwesimo kuyenzeka. Esikhathini esizayo lokhu kufaka isandla ekuthuthukiseni izifo nezifo ezitholwa njengefa.
Muva nje, isixhumanisi sisunguliwe phakathi kwezinkinga zemvelo nezenhlalo, kepha umthelela usobala. Izinkinga eziningi ezidalwe ngumphakathi ziphenduka zibe eziningana zezemvelo. Ngakho-ke, umsebenzi osebenzayo we-anthropogenic awonakalisi nje kuphela umhlaba wemvelo, kepha futhi uholela ekuwohlokeni kwempilo yawo wonke umuntu.
