Ukususela kwixesha elidlulileyo, umbono wesiphelo sehlabathi uye wabamba ingcamango yomntu. Enoba kusentsomini, kunqulo, okanye kwisithethe esithandwayo, ingcamango yentlekele ephelisa ubukho bethu iye yathethwa kakhulu yaye yoyikwa. Kuye kwafikelela kwinqanaba lokuba kukho iimuvi ezininzi kunye neethiyori malunga Isiphelo Sehlabathi. Ngaba izazinzulu ziya kuchaneka malunga nokuqikelelwa kwesiphelo sehlabathi okanye ziya kuba ziphosakele?
Kweli nqaku siza kukuxelela ngeethiyori eziphambili kunye nolwazi olukhoyo malunga nokuphela kwehlabathi.
Isiphelo sehlabathi ngokwembono yesayensi
Xa sithetha ngesiphelo sehlabathi ngokwembono yenzululwazi, singena kwiindawo apho iingozi ziyinyani kodwa nezisombululo ezinokubakho. Enye yeemeko ezikhankanywe kakhulu kukutshintsha kwemozulu.. Ukufudumala kwehlabathi okubangelwa yimisebenzi yabantu kuye kwabangela inkxalabo yehlabathi jikelele ngenxa yempembelelo yayo kwimozulu, i-ecosystem kunye nobomi emhlabeni. Ukuba akuthathwa amanyathelo okunciphisa ukukhutshwa kwegesi ye-greenhouse, sinokujamelana nemiphumo emibi, kuquka ukunyuka kwamaqondo olwandle, imbalela egqithisileyo, kunye neziganeko zemozulu eziyingozi.
Enye imeko exhalabisayo yezenzululwazi kumngcipheko wobhubhane wehlabathi. Ingxaki yamva nje ye-COVID-19 iveze ukuba sesichengeni kwethu ekusasazeni izifo ezosulelayo kakhulu. Nangona siye sakwazi ukuphuhlisa izitofu zokugonya ezisebenzayo kunye nokuphucula amandla ethu okuphendula, kuhlala kukho into yokuba i-pathogen entsha inokuvela, yongamele ukhuseleko lwethu kwaye ibangele unxunguphalo lwempilo yehlabathi.
Kwakhona, kukho inkxalabo malunga neziganeko ze-cosmic ezifana neempembelelo ze-asteroid. Nangona amathuba empembelelo yentlekele esezantsi, umngcipheko uhleli kwaye izazinzulu zisebenza ekubhaqweni nasekujikeni ii-asteroids ezinokuba yingozi.
Olunye uhlobo lwesiphelo sehlabathi imfazwe yenyukliya. Ukubakho kongquzulwano olupheleleyo lwenyukliya kusesisisongelo sokwenene. Ukufikelela kwizixhobo zenyukliya kunye noxinzelelo phakathi kwamazwe kuye kwaqhubeka ukuba yinkxalabo ukususela ekuqaleni kwemfazwe phakathi kweRashiya ne-Ukraine. Ungquzulwano olupheleleyo lwenyukliya lunokuba neziphumo ezibi kwimpucuko yabantu nakwimekobume, nto leyo ebangela ukutshatyalaliswa okubanzi kunye nexesha elide.
Isiphelo sehlabathi ngokwembono yefilosofi
Ngaphandle kweemeko zenzululwazi, isiphelo sehlabathi sikwangumxholo wokubonakaliswa kwefilosofi kuyo yonke imbali. Ezinye izikolo zeengcinga ziphikisa ukuba isiphelo sehlabathi Ayibhekiseli ekutshatyalalisweni ngokwasemzimbeni kwesi sijikelezi-langa, kodwa kutshintsho olusisiseko kwimeko yomntu.
Ngokwale mbono, isiphelo sehlabathi sinokubonwa njengokulahlekelwa kwezinto ezibalulekileyo zobuntu, ukuthotywa kwemekobume, ukutshatyalaliswa kweyantlukwano yenkcubeko, okanye ukulahleka kovelwano kunye nomanyano. Le mibono yefilosofi iphakamisa ukuba kunokwenzeka ukuba isiphelo sehlabathi yinkqubo ehamba ngokuthe ngcembe, ilahleko eqhubekayo yezinto ezisenza sibe ngabantu, kunokuba isiganeko esingalindelekanga kunye nentlekele. Kunokuthiwa yilahleko enkulu eluntwini kunokuphela kwehlabathi njengoko kunjalo, kuba iplanethi enguMhlaba inokuqhubeka nokusebenza ngaphandle kwabantu ekubeni sisinye indalo.
Iifomu ezinokwenzeka ngokweHarvard
Ngokophononongo lwakutsha nje oluvela kwiYunivesithi yaseHarvard, isiphelo sehlabathi siqikelelwa ukuba senzeke ngendlela efanayo ekuqaleni kwayo: ngogqabhuko-dubulo olukhulu. Uqikelelo lwangaphambili lucebise ukuba intshabalalo yoMhlaba ingenzeka ngeziganeko ezifana nemfazwe yenyukliya, ukungqubana kwemeteorite enkulu, okanye ukuncipha kancinci kancinci ebumnyameni.
Nangona kunjalo, izazinzulu ngoku zikholelwa ukuba ukutshatyalaliswa kweqhekeza elibizwa ngokuba yi-Higgs boson, uxanduva lobunzima bayo yonke into, kuphela okufunekayo kwesi siganeko sibi. Ngelixa esi siganeko soqhushumbo kuqikelelwa ukuba siza kwenzeka malunga ne-11 yeebhiliyoni zeebhiliyoni ukususela ngoku, akunakwenzeka ukuba kubekho nabani na kuthi oza kuzibonela. Ngaphandle kokuba inkqubela yenzululwazi isivumela ukuba sibe ngumkhenkce kwaye sivuswe kwiinkulungwane kamva, kwimeko apho kufuneka silumke. Xa amaza okuphelisa uzinzo eqala ukusebenza, oko kuya kubangela iqamza elikhulu lamandla eliya kuba ngumphunga litshatyalalise yonke into esendleleni yalo, kuquka nabo basenokuba baye benza iMars.
Kukho iinkxalabo phakathi kweefiziksi ukuba inkqubo sele iqalile. Into exhalabisayo kukuba asinakuze sazi ngokuthe ngqo ukuba isiphelo sikufuphi nini ngaphandle kokuba thina sisenokukwazi ukulifumana “iNqakule likaThixo” kwindawo yethu enkulu yendalo iphela. Ngaphaya koko, kukho ithuba elinamandla lokuba iziganeko eziyingozi ezinjengokutshiswa nokudubula kweLanga ziya kwenzeka ngaphambi kwalo mhla wentshabalalo.
xa litshona ilanga
Ukuba kunokwenzeka ukuba i-apocalypse yenzeke ngokukhawuleza kunokuba ivele kuthi. Kumalunga nomzuzu apho inkwenkwezi ekhanyisa umhlaba wethu itshabalala. Nangona elona xesha esenzeka ngalo esi siganeko lingaziwa, ngo-2015 iteleskopu yakwaKepler yakwazi ukuthabatha okokuqala intsalela yesijikelezi-langa, nto leyo esinika umbono wento enokusifumbathele ikamva lethu kwiminyaka ezayo.
Abaphandi abakhokelayo kwimishini baye bafumanisa iintsalela zesijikelezi-langa esinamatye kwindawo yokubola, ejikeleza i-dwarf emhlophe. Ngundoqo ovuthayo oshiyekileyo wenkwenkwezi emva kokuba amandla ayo enyukliya kunye namafutha aphelile.. Ngokophononongo olupapashwe kwijenali ethi 'Nature', ukuhla okuthe gqolo kokuqaqamba kwentonga emhlophe, eyehla ngama-40% rhoqo kwiiyure ezine ezinesiqingatha, luphawu olucacileyo lwamaqhekeza amatye amaninzi eplanethi ewohlokayo ejikeleza kwindawo enye. intshukumo ejikelezayo.
Nje ukuba i-fuel ye-hydrogen yeLanga iphelelwe, izinto ezixineneyo ezifana ne-helium, ikhabhoni, okanye ioksijini ziya kuvutha kwaye zande ngokukhawuleza, ziphelele ekuchithekeni koqweqwe lwazo lwangaphandle kunye nokudala inkwenkwezi. undoqo. Nje ngeziphumo, iya kutshabalalisa ihlabathi lethu, kunye neVenus kunye neMercury.
Ndiyathemba ukuba ngolu lwazi unokufunda ngakumbi malunga neemeko ezahlukeneyo malunga nesiphelo sehlabathi esisilindeleyo.
