Izinkinga zemvelo

Izinkinga ezithinta imvelo - ezicini eziningana lapho kusho nokucekelwa phansi kwemvelo. Ngokuvamile basuke abangelwa izenzo zabantu: ukuthuthukiswa umkhakha nobuchwepheshe baqala ukuzwa izinkinga ezihlobene ukwephulwa kwemibandela onokulinganisela imvelo imvelo, okuyinto okunzima kakhulu leso sikhala.

Enye yezinto nokucekela phansi kunazo zonke izenzo zabantu - ukungcola. It kubonakala anda amazinga ngentuthu, nesenzakalo amachibi efile, amanzi zezimboni ayegcwele izinto ezilimazayo futhi ongakulungele ukudliwa ngabantu, kanye ngenxa ukuqothulwa kwezinye zezinhlobo.

Ngakho, umuntu, ngakolunye uhlangothi, kudala izimo ukuze sithole induduzo, futhi nomunye - ebhubhisa nemvelo futhi efanele ibe kuhlu lokuhlukumezeka, ekugcineni, yena. Ngakho-ke, ukunakwa yamuva e imvelo zezemfundo kunikezwa izinkinga main kwemvelo futhi siqondiswe Ukufuna izindlela.

nezindaba ezisemqoka kwemvelo

Ekuqaleni izinkinga zemvelo olwabiwa izimo isikali: kungenzeka ukuthi yesifunda, zendawo global.

Isibonelo inkinga yendawo kwemvelo kuyinto isitshalo abumenzi Amanzi anokungcola kwasezimbonini ngaphambi kokuba akhishwe emfuleni. Lokhu kuholela izinhlanzi ukubulawa futhi efanele ibe kuhlu lokuhlukumezeka abantu.

Njengoba isibonelo izinkinga lesifunda kungathatha EChernobyl - noma kunalokho, inhlabathi, okuyizinto eseduze nale ndlela: zingabantu enemisebe futhi usongo kunoma eziphilayo zokwakheka kukhona endaweni.

Siyobe banake izindaba phansi kwemvelo embulungeni yonke.

izinkinga Global kwemvelo lesintu: isici

Lolu chungechunge izinkinga zemvelo has ububanzi amakhulu oluthinta ngqo zonke izimiso zokusebenza kwemvelo, ngokungafani kuya endawo nawesifunda.

Nezokongiwa Kwemvelo: ukufudumala kwembulunga yonke futhi imbobo-ozone

Kwembulunga zezakhamuzi eMhlabeni uyazwelana Ubusika nobumnene, ubukade ezingavamile. Njengoba kokubili izintambo wokuqala international ngonyaka Geophysics, ezimfushane lokushisa air ungqimba luyanda 0.7 ° C. Ngezinye isigxobo enyakatho izingqimba engezansi ice zaqala ukugcwala amanzi ngenxa yokuthi amanzi kusifudumeza-1 ° C.

Abanye abacwaningi banomuzwa wokuthi isizathu lesi simanga - okuthiwa "Amagesi Abamba Ukushisa Emkhathini", nesuka lemali elikhulu amandla omlilo of amafutha kanye ukunqwabelana kwe-carbon dioxide ezingqimbeni ozungeze umhlaba wethu. Ngoba sinqamukile nokushisa futhi umoya selehlile kancane.

Abanye bakholelwa ukuthi ukufudumala kwembulunga kungenxa yomsebenzi elanga futhi isici womuntu akusho badlala indima ebalulekile.

Ozone imbobo - enye inkinga yesintu, ezihlobene intuthuko kwezobuchwepheshe. Kuyaziwa ukuthi ukuphila emhlabeni kwakuvela kuphela ngemva umsuka zokuzivikela ungqimba lwe-ozone esivikela eziphilayo emisebeni enamandla UV.

Kodwa ngasekupheleni kwekhulu lama-20, ososayensi bathola ukuthi phezu Antarctic kuyinto-ozone kancane kakhulu. Lesi simo iqhubeka kuze kube manje, endaweni ezilimele ngesikhathi esifanayo uyalingana ingakanani eNyakatho Melika. anomalies batholakala ezinye izindawo, ikakhulukazi, imbobo i-ozone laphaya Voronezh.

Isizathu salokhu - esebenzayo ukuqaliswa lwamarokhethi kanye iziphuphutheki, kanye izindiza.

Izinkinga ezithinta imvelo: ugwadule kanye Ukucekelwa phansi kwamahlathi

nemvula ene-asidi, imbangela okuyinto - umsebenzi amandla, kunomthelela ekusakazekeni lomunye global inkinga - kuqothulwa kwehlathi. Ngokwesibonelo, eCzechoslovakia ezingaphezu kuka-70% amahlathi libhujiswa lezi izimvula, futhi zase-UK Greece - angaphezu kuka-60%. Ngenxa yalokhu, lonke isimiso semvelo ziphuliwe Nokho, isintu besilokhu uzama ukulwa le izihlahla eyayenziwe watshala.

Ugwadule futhi manje yinkinga yembulunga yonke. It itholakala phansi kwenhlabathi: ezindaweni ezinkulu engafanele ukusetshenziswa emkhakheni wezolimo.

Man kunomthelela ezindaweni ezinjalo, ethwele hhayi kuphela emhlabathini, kodwa futhi idwala umzali.

Izinkinga ezithinta imvelo obangelwa amanzi

amanzi ahlanzekile, ehlanzekile engasetshenziswa, kakhulu, kuthiwa kakhulu ziyancipha eminyakeni yamuva. Lokhu kungenxa yokuthi abantu nilingcolise ngayo ezimbonini kanye nezinye.

Namuhla, i-yizigidi eziyizinkulungwane nengxenye abantu intula amanzi okuphuza ahlanzekile futhi bukhoma eziyizinkulungwane ezimbili ngaphandle izihlungi ukuhlanzwa amanzi angcolile.

Ngakho, singasho ukuthi zamanje nezesikhathi esizayo izinkinga eziningi zemvelo isintu unecala uqobo futhi ubhekane nabanye babo kule minyaka 200-300 esilandelayo.
