Izinkinga zemvelo Global nezisombululo zabo

Engxenyeni zenzeka ekhulwini lamashumi amabili wesibili, emnothweni isintu ngohlobo ezizungezile ifinyelele ngezabelo enjalo elimazayo ukuthi Wacishe ikhono lokuzelapha.

izinkinga embulungeni yonke imvelo nokuthuthukiswa okugcinekayo - inkinga ukumisa nomthelela wezenzo zabantu eziyingozi emvelweni.

Phakathi nekhulu leminyaka eledlule, ngemvelo kwaba lithandana sangaphakathi ezweni elithile, njengoba imiphumela yokungcoliswa ngenxa yomsebenzi zezimboni kubonakala kuphela ezindaweni lokuhlala lasetulu kakhulu izimboni enobungozi. Eighties, izinkinga zemvelo ngiye ngazuza ezingeni lesifunda, kusukela kwekhabhoni steel ukufinyelela emazweni angomakhelwane, eza kanye kwezulu, umoya.

Ngo nineties, enkundleni waya izinkinga zamazwe omhlaba onke kwemvelo isintu. Bona azibonakalisa ezifana imikhuba emibi njengoba ukubhujiswa emhlabeni-ecosystem, izinsiza, ukulahlekelwa ikhono lokuzelapha, ukunwetshwa esishintshashintshayo lwenhlekelele semvelo. Kodwa kuyingozi enkulu kakhulu esikhathini sethu siba kwesimo sezulu. Ukwandisa izinga lokushisa laminyaka yonke kuwubufakazi esihambelana imvamisa kakhudlwana futhi ukushuba extreme sezulu imicimbi: izikhukhula, isomiso, iziphepho, yesithwathwa okuzumayo thaws. Ngaphezu kwalokho, ukufudumala kungaholela yokwenyuka kwamazinga olwandle, ugcwalise ezindaweni ezinkulu, babhebhethekisa ukusweleka nomthombo wamanzi aqabulayo. Konke lokhu kubangela isimo lwesintu umonakalo omkhulu.

Ukushintsha kwesimo sezulu ezihlobene nokwanda lokuhlushwa amagesi abamba ukushisa emkhathini, isb anda "Amagesi Abamba Ukushisa Emkhathini". amagesi elimazayo emkhathini kusukela amandla omlilo uphethiloli, ukuqothulwa kwamahlathi kanye nokunye. Nokho, kukhona esinye umbono ukuthi imbangela wonke akuzona izinkinga phansi kwemvelo embulungeni yonke, futhi isigqi wakudala solar umsebenzi kanye sezulu imijikelezo.

imiphumela yokungcoliswa

Imiphumela esemqoka yokungcola itholakala lokuthi ukuthi umonakalo ongalungiseki isilwane nasezimpilweni zabantu, izindawo kakhulu okunobuthi babe engafanele abantu bahlale kuwo futhi imisebenzi evamile. The main izinkinga zemvelo besikhathi sethu, uma kungekhona ziqondiswe, kungenzeka ziholele iqiniso lokuthi uHlu Jikelele Lwamakheli; ulahlekelwe ngokuphelele ikhono ahlanze ngokwayo bese uyivala.

inchubomgomo yembuso

Okubi kakhulu zezinkinga phansi kwemvelo embulungeni yonke kuye kwaholela ushintsho inqubomgomo kahulumeni emazweni amaningi mayelana nokuvikelwa kwemvelo. Iziphathimandla wasungula izimiso zemvelo, ukuchitha okwengeziwe izinyathelo kwemvelo.

Eighties komphakathi weentjhabatjhaba uye waqaphela ukuthi izinkinga phansi kwemvelo embulungeni yonke ayikwazi ixazululwe ngaphakathi uthi ngabanye. It uye wazakhela nomqondo intuthuko eqhubekayo, owawuthi amazwe kudingeka ukuqinisekisa ukuthuthukiswa izidingo isizukulwane samanje kodwa futhi esizayo hhayi kuphela. Ngenxa yalokho, kukhona ukuphikisana: kanjani ukuqinisekisa intuthuko eqhubekayo futhi ngesikhathi esifanayo ukunciphisa umthelela emvelweni. Ngo-1997, i-Kyoto Protocol kwenza kwaba nomfutho omkhulu ecacisa imiqulu esiphezulu kwekhabhoni eziyingozi amagesi abamba ukushisa. Injongo eyinhloko yawo Protocol - yokunciphisa intuthu engcolisa umoya ka 5.2% uma kuqhathaniswa amazinga 1990.

Namuhla, emazweni amaningi athuthukile baye bakwazi kakhulu ukunciphisa izinga ukungcola, noma okungenani ukuyihlalisa. Kufanele kuqashelwe ukuthi ukuncipha kokungcoliswa komoya kungadla kungcono eqolo, futhi izinzuzo kuyobonakala kuphela esikhathini eside. Nokho, izinkinga phansi kwemvelo embulungeni yonke kudingeka zixazululwe, kodwa izindleko kuzomelwe babhekane manje, ukuze kamuva kwase kwephuzile.
