La ubuchwepheshe obuluhlaza kancane kancane iqala ukuduma, okwamanje imikhakha eminingi isebenzisa ukusetshenziswa kwayo, ifunde okwengeziwe ngale nqubo esiza iplanethi.
Amaphaneli elanga, ubuchwepheshe obuluhlaza
Bumayelana nani ubuchwepheshe obuluhlaza?
La ubuchwepheshe obuluhlaza, ngokushesha ehlotshaniswa njengento ezimele ezuzisa iplanethi, igama eliluhlaza lithole indawo embonini yezobuchwepheshe.
Futhi kwezinye izinhlangano zikahulumeni futhi kamuva nje emakhaya; Kodwa buyini lobu buchwepheshe noma la madivayisi amayelana ngqo? Siyini isicelo sakho, yini ukusebenza kwaso?
Hhayi-ke, lobu buchwepheshe busekelwe ekusetshenzisweni kwezixazululo namadivayisi asekelwe ekusebenzeni kahle kwemvelo; okungeyona into engaphezu kwesiqinisekiso nokuphepha enziwa ngakho, kanye nempumelelo ekusebenzeni kwazo.
Ukunciphisa kakhulu umthelela wabo kwezemvelo, usebenzisa izinsiza ezimbalwa ngaphandle kokunciphisa umthamo noma ukusebenza, ngokuphambene nalokho, bandisa ukusebenza kahle kwabo.
Kodwa-ke, okuluhlaza kubuye kusetshenziswe njengehange lokukhangisa ukuze kuqashelwe abathengi abafuna ukuqaphela ukuphathwa kwemvelo. Manje ungayibona kanjani imikhiqizo yezobuchwepheshe eluhlaza?
Ukuhlonzwa komkhiqizo oluhlaza
Ukuze ungenzi iphutha futhi wazi uma uphambi komkhiqizo oluhlaza noma ohlangabezana nezidingo zobuchwepheshe obuzinzile ngokwezemvelo, kufanele unake lokhu okulandelayo:
Banokusetshenziswa okuphansi kwamandla kagesi, amadivaysi amasha anesidingo esiphansi sikagesi. Lokhu kubaluleke kakhulu emazweni lapho le nsiza ikhiqizwa ezimbonini zikagesi ezisebenzisa amalahle njengempahla eluhlaza.
Ngokuvamile, ilebula enolwazi ingaboniswa noma kwezinye izimo emikhankasweni yokukhangisa igcizelela lezi zakhiwo.
Zinokuncipha okukhulu kokusetshenziswa kwezakhi ezinobuthi, okubalulekile lapho uhlukanisa umkhiqizo njengoluhlaza.
Ungaba sebukhoneni bomshini osebenzisa amandla kagesi aphansi; kodwa lokhu akusho ukuthi akwenziwanga ngezinto eziyingozi kubantu nasemvelweni.
Uma kunjalo, lapho umkhiqizo ufinyelela ukuphila kwawo okuwusizo futhi ulahlwa, ubuthi noma izinto ezinobuthi ziyowohloka endaweni ebangela umonakalo noma ukungcola.
Ngenxa yalesi sizathu, kubalulekile ukuqaphela ukuthi imikhiqizo ethengiwe ayinayo i-lead, i-mercury, i-cadmium ne-barium. Uma ungakunaki lokhu, kungagcwaliswa ngemikhiqizo ebizwa nge-electronic waste.
Imigomo Yobuchwepheshe Obuhlaza
Enye yezinjongo eziyinhloko ukwanelisa izidingo ezidingwa umphakathi, ngaphandle kokubeka izinsiza zezizukulwane ezizayo.
Futhi nokuthi izixazululo ezithuthukisiwe ziyaqhubeka nokusetshenziswa ngokuhamba kwesikhathi unomphela ukuze kuqinisekiswe ukuthi zingenzeka.
Indlela yobuchwepheshe obuluhlaza kufanele icabangele ubude besikhathi esigcwele sokusebenziseka komkhiqizo wokugcina. Kusukela ekuzalweni kwayo kuye ekubhidlikeni kwayo, ngendlela engatholakala, iphinde isetshenziswe noma igaywe kabusha.
Le mikhiqizo kufanele ikhuthaze ushintsho kumkhuba wokusetshenziswa. Ngenhloso yokuthi kusiza ukunciphisa udoti wezobuchwepheshe, ukusetshenziswa kukagesi kanye nokungcola.
Ukwengeza, lokhu kwehliswa kumele kube yingxenye yezimiso zokudala, ukukhiqiza, ezokuthutha kanye nendawo yokugcina.
Izinto, izinto zokwakha noma izinqubo kumele zenziwe eziyi-avant-garde nenoveli noma kutholwe ukusetshenziswa okusha kwalezi ezikhona. Ukuba nesisekelo inzuzo yabantu, ngaphandle kokubandlulula imvelo.
Imikhiqizo kufanele ikwazi ukufakwa emikhakheni yezomnotho, ukuthi ukusetshenziswa kwayo kuthuthukiswe ngezindlela ezanele nokuthi inzuzo efunwayo akuyona nje imali, kodwa ayinayo imiphumela eyingozi yesibili.
izibonelo zobuchwepheshe obuluhlaza
Inkinga eqhubekayo yileyo yamandla. Kusetshenziswa ubuchwepheshe obuluhlaza ukuze kutholwe amafutha kanye nezindlela zokukhiqiza ugesi ngenye indlela kuneyakudala, ngenhloso yokwenza lula ukutholakala nokuvikela iplanethi.
Lezi zakhiwo okuthiwa eziluhlaza zingenye yezifiso ezinkulu zabakhi nabadwebi banamuhla. Ngokukhula, emhlabeni wonke lezi zakhiwo ziyabonwa.
I-Nanotechnology iyindawo esacwaningwayo, enamandla amakhulu okuthi esikhathini esizayo iguquke futhi iguqule ngokuphawulekayo imibono yethu yempilo yamanje, iyenze ishintshe ngendlela esiyazi ngayo.
Kumakhemikhali, i-physics kanye ne-biology, ngokubambisana nezinye isayensi efanayo, bagxile ekunikezeni ithuba elibalulekile emikhiqizweni ezosetshenziswa njalo, kusukela ekudleni, okokuhlanza, okokufaka, izingubo, ifenisha, njll.
Lokhu ukuze kuncishiswe noma kuqedwe ngokuphelele ukusetshenziswa kwezinto ezinobuthi noma eziyingozi kubantu noma endaweni.
Amandla elanga afinyelela emhlabeni ngendlela yama-photon angashintshwa abe ugesi noma ukushisa. Ukuze kuzuzwe lokhu, izibuko nezitsha ze-parabolic zisetshenziselwa ukugxilisa lawo mandla futhi zigcinwe ukuze zisetshenziswe kabusha futhi ngesikhathi esifanayo zingakhiqizi ukungcoliswa kwemvelo.
Kafushane, kulinganiselwa ukuthi ngonyaka wezi-2030 inani labantu lizokwanda kakhulu. Idinga amandla angama-60% ngaphezulu kwalawo asetshenziswa njengamanje.
Uma unentshisekelo ekusetshenzisweni kabusha kwezisetshenziswa vakashela isixhumanisi esilandelayo ku isitsha esigoqekayo futhi uthole okwengeziwe.
