Iplanethi yethu inenqwaba yemithombo yemvelo. Lokhu kufaka amadamu kanye nenhlabathi, umoya namaminerali, izilwane nezitshalo. Abantu basebenzise zonke lezi zinzuzo kusukela ezikhathini zasendulo. Kodwa-ke, namhlanje kuvele umbuzo obukhali ngokusetshenziswa okunengqondo kwalezi zipho zemvelo, ngoba abantu bazisebenzisa ngokweqile. Ezinye izinsiza zisengcupheni yokuphela futhi zidinga ukubuyiselwa ngokushesha okukhulu. Ngaphezu kwalokho, zonke izinsizakusebenza azabiwe ngokulinganayo ngaphezulu komhlaba, futhi ngokwezinga lokuvuselelwa, kukhona lezo ezilulama ngokushesha, futhi kukhona lezo ezithatha amashumi noma ngisho namakhulu eminyaka lokhu.
Izimiso zemvelo zokusetshenziswa kwemithombo
Ngenkathi yokuthuthuka kwezesayensi nezobuchwepheshe hhayi kuphela, kepha esikhathini sangemva kwezimboni, ukuvikelwa kwemvelo kubaluleke kakhulu, ngoba phakathi nentuthuko, abantu banomthelela omkhulu emvelweni. Lokhu kuholela ekusetshenzisweni ngokweqile kwemithombo yemvelo, ukungcoliswa kwendawo kanye nokuguquka kwesimo sezulu.
Ukuze kugcinwe ubuqotho be-biosphere, kunezimo eziningana ezidingekayo:
- kucatshangelwa imithetho yemvelo;
- ukuvikelwa nokuvikelwa kwemvelo;
- ukusetshenziswa okunengqondo kwezinsizakusebenza.
Isisekelo semvelo semvelo okufanele silandelwe yibo bonke abantu ukuthi simane siyingxenye yemvelo, kepha hhayi ababusi bayo. Lokhu kusho ukuthi kudingekile hhayi kuphela ukuthatha kwimvelo, kepha futhi nokunikela, ukubuyisa izinsiza zayo. Isibonelo, ngenxa yokugawulwa okukhulu kwezihlahla, izigidi zamakhilomitha emahlathini zonakalisiwe, ngakho-ke kunesidingo esiphuthumayo sokunxephezela ukulahleka nokutshala izihlahla endaweni yamahlathi agawuliwe. Kuzoba wusizo ukuthuthukisa imvelo yamadolobha anezikhala ezintsha eziluhlaza.
Izenzo eziyisisekelo zokusetshenziswa okunengqondo kwemvelo
Kulabo abangajwayelene nezinkinga zemvelo, umqondo wokusetshenziswa okunengqondo kwezinsizakusebenza ubukeka ungumbuzo ongacacile. Eqinisweni, konke kulula kakhulu:
- udinga ukunciphisa ukuphazamiseka kwakho nemvelo;
- sebenzisa imithombo yemvelo okuncane ngangokunokwenzeka ngokungadingekile;
- vikela imvelo ekungcolisweni (ungatheleli ukungcola emanzini nasemhlabathini, ungangcolisi);
- shiya izimoto uthanda ukuthuthwa kwemvelo (amabhayisikili);
- konga amanzi, ugesi, igesi;
- yenqaba izinto ezilahlwayo nezimpahla;
- ukuzuzisa umphakathi nemvelo (khulisa izitshalo, wenze izinto ezinengqondo, sebenzisa ubuchwepheshe bezemvelo).
Uhlu lwezincomo “Uyisebenzisa kanjani imithombo yemvelo ngokufanele” alupheli lapho. Umuntu ngamunye unelungelo lokuzinqumela ukuthi uzozikhipha kanjani izinzuzo zemvelo, kepha umphakathi wanamuhla udinga ezomnotho nokuqonda, ukuze sikwazi ukushiyela inzalo yethu imithombo yemvelo abazoyidinga impilo yonke.
