Ezweni lanamuhla, isidingo sokuthi abantu basebenzise izinsiza zamandla siyakhula. Okwamanje, lezi zinhlobo zemithombo elandelayo yomkhakha wamandla ziyaxhashazwa:
- uphethiloli wamalahle - amalahle, igesi;
- amanzi;
- i-nucleus ye-athomu.
Amandla we-athomu namandla wamanzi aguqulwa abe ugesi, ahlinzekwa kubantu ukuze bathole usizo lokuphila ezindaweni zokuhlala. Kulokhu, imikhiqizo yomlilo ikhishelwa emkhathini, okwenza isimo semvelo yendawo sibe sibi kakhulu.
Amandla ayithinta kanjani imvelo?
Ngokuvamile, imboni yamandla inomthelela omuhle emnothweni. Ngokuqondene nemvelo, amandla anomthelela omubi kuwo:
- ifaka isandla ekuguqukeni kwesimo sezulu;
- kukhona ushintsho kuhulumeni wamanzi emifula;
- ukungcoliswa kwamanzi oLwandlekazi Lomhlaba ngamakhemikhali;
- kuthinta ukubonakala kwemvula ene-asidi;
- umkhathi ungcoliswe amagesi, uthuli, ukukhishwa okuyingozi;
- kwakhiwa umphumela wokushisa;
- kukhona ukungcoliswa kwemisebe namakhemikhali kwe-lithosphere;
- imithombo yemvelo engavuseleleki iyaphela.
Phakathi kwezinye zezinkinga emkhakheni wezamandla, imishini engaphephile yezinhlobo ezahlukahlukene zezitshalo zamandla, kungaba ezishisayo noma ezenuzi, ibalulekile. Kukhona nenkinga yokulahlwa kwemfucumfucu enemisebe, ngoba kufanele ibekwe yodwa futhi igcinwe ngokuphepha, okudinga udoti omkhulu wezezimali.
Umphumela
Mhlawumbe kuzolunga ukusho ukuthi hhayi kuphela izimpilo zabantu ezihlala eduze kwesikhungo samandla, kepha futhi nabo bonke abantu emhlabeni, isimo semvelo jikelele sincike ekunakekelweni, emandleni nasekhonweni labasebenzi bezikhungo eziphehla ugesi ezishisayo, izikhungo zamandla enuzi, izikhungo zamandla kagesi ophehlwa ngamanzi. Mayelana nalokhu, isixazululo sezinkinga zamandla sizothinta isisombululo sezinkinga ezinkulu zemvelo zeplanethi.
