Inkinga enkulu ukuncipha kwemithombo yemvelo. Abasunguli sebesungule amasu amaningi azosiza ukusebenzisa le mithombo ekusetshenzisweni komuntu siqu nakwezimboni.
Ukubhujiswa komhlaba nezihlahla
Umhlabathi nehlathi kuyimithombo yemvelo evuselela kancane. Izilwane ngeke zibe nemithombo yokudla eyanele, futhi ukuze zithole izinsiza ezintsha, kuzofanele zihambe, kepha eziningi zisengcupheni yokuqothulwa.
Ngokuqondene nehlathi, ukugawulwa okunamandla kwezihlahla okusetshenziswa izingodo, ukukhishwa kwezindawo ezintsha zezimboni nezolimo, kuholela ekuqothulweni kwezitshalo nezilwane. Futhi lokhu kuthuthukisa umphumela wokubamba ukushisa futhi kubhubhise ungqimba lwe-ozone.
Ukubhujiswa kwezimbali nezilwane
Izinkinga ezingenhla zithinta iqiniso lokuthi izilwane nezitshalo ziyabhujiswa. Ngisho emadamini, kunezinhlanzi ezingaphansi nezincane, ibanjwa ngobuningi obukhulu.
Ngakho-ke, imithombo yemvelo enjengamaminerali, amanzi, ihlathi, umhlaba, izilwane nezitshalo kuyabhujiswa ngesikhathi semisebenzi yabantu. Uma abantu beqhubeka nokuphila kanjena, kungekudala iplanethi yethu izoncipha kangangokuthi ngeke sisaba nezinsizakusebenza zokuphila.
