I-Light Initiative

Ngonamakhulu eminyaka, wonke umuntu obheka phezulu ngemini ecacile wabona into efanayo: amawaka ezinkanyezi kanye nomfula omnyama wendlela ye-milk. Ihlela amakhalenda, ukushayela, izimfundiso nezifundo. Empilweni eyodwa siyifihla eduze kwe-dome ekhanyayo yelanga elilahlekile. I-Light Initiative ikhona ukuyibuyisela emuva, futhi le yinkinga eyodwa yemvelo engayixazululwa ngobusuku obuthile uma ukhetha ukuyilungisa.

Isibhakabhaka sebusuku ngamanombolo

Ngokusho kwe-atlas yezwe yokukhanya kwesibhakabhaka esikhiqizwe, iphesenti le-80 labantu emhlabeni wonke, kanye ne-iphesenti le-99 abantu eMelika naseYuropu, baphila ngaphansi kwezinga lokukhanya okubi. Omunye kuthathu abantu emhlabeni ngeke bakwazi ukubona iMilky Way lapho behlala khona. futhi kuqhubeka kungenakulungile: amawaka ambalwa ochwepheshe abaphilayo bebala izinkanyezi bathola ukuthi izulu lemini likhanya ngo- 9.6% ngonyaka phakathi kuka-2011 no-2022, okusho ukuthi ukukhanya kuncane kunaleso seminyaka emihlanu.

Izindaba ezinhle

Ngaphandle kwegesi ye-greenhouse, ukukhishwa kokukhanya akuqoqwa. Vala, vikela noma ugweme ilanga futhi ukumnyama kubuyela ngokushesha. Izixazululo zibiza kakhulu, zitholakala kuwo wonke ama-hardware shop, futhi zivame ukulondoloza imali kugesi. Izifunda, iziqhingi kanye nezikhumbuzo ezigcwele emhlabeni wonke ziye zathola ubufakazi bokuthi ziyizindawo zezulu elimnyama ngokushintsha amalambu abo.

Uthuli olukhanyayo luyingozi encane kuphela elahlekile uma uvala.

Imisebenzi ye-Light Initiative

• Ichaza ukukhishwa kwelanga nokungcola kwayo ngesilimi esilula: bona iyini i-light pollution.
• Ibonisa ukuthi ungayilungisa kanjani, ngemiyalelo esebenzayo yezindlu, izimakethe namadolobhana: bona ukukhanya kwelanga ngaphandle ngokuzimela.
• Ixhuma isibhakabhaka nokufundeka. I-indawo yokufundeka yendawo yethu emahhala iqala ngesibhakabhaka ngakwesokudla kwakho.
• Ixhasa imisebenzi yasekhaya, njengezimini ezimnyama zezulu, ukubala izinkanyezi nokuxoxwa namaqembu, okuhlelwe ngabahlanganyeli ngebhodi le-contribution board.

Ingabe isibhakabhaka sakho simnyama?

I-Light Pollution Map ngu-Yurij Stare ibonisa ukukhanya kwesibhakabhaka okungenziwa nguNkulunkulu nakweyiphi na indawo emhlabeni, ngokuya ngedatha yesathelayithi. Iphrojekthi yesayensi yama-citizen IGlobe ngeNdlela ivumela wonke umuntu ukuthi alinganise isibhakabhaka sakhe ngaphandle kokubheka, futhi ifaka ukubala kwakho kwirekhodi lezwe lonke.

Ungasiza kanjani

• Bala izinkanyezi zakho. Qaphela i-Globe at Night izikhathi ezimbalwa ngonyaka; ukubheka kwakho kwenziwa kube yidatha.
• Isiqiniseko sezibani zakho kuqala: zivikela, zikhombise phansi, zifudumele, zimnyama futhi uzibeke ezimininingwaneni noma ezinqola u movement.
• Xhumana nabangani bakho. Amanye amalambu akhanyayo ashiya phezulu ngenxa yesimo, hhayi isidingo. Ukuxhumana okumnandi kanye nencwadi equkethe lekhasi kuvame ukusebenza.
• Write to your council. Ask for a lighting policy with full shielding, warm colour temperatures of 3000 K or lower, dimming after midnight, and dark-sky protection for parks.
• Buza izinhlangano zomphakathi ukuthi zivale izinkomba kanye namalambu emoto ngemuva kokuvala.
• Hlanganisa iqembu le-star. I-telescope ngemini emnyama ishintsha izingqondo ngokushesha kunanoma iyiphi isibalo. Qala enye nge ibhodi lokungenisa.
