Umkhathi uyimvilophu eyisiplanethi yethu. Kungenxa yalesi sikrini esivikelayo ukuthi impilo eMhlabeni kungenzeka kakhulu. Kepha, cishe nsuku zonke sizwa imininingwane yokuthi isimo somkhathi siyawohloka - ukukhishwa kwezinto eziyingozi, inani elikhulu lamabhizinisi asezimbonini angcolisa imvelo, izinhlekelele ezahlukahlukene ezenziwe ngabantu - konke lokhu kuholela emiphumeleni emibi kakhulu, okungukucekelwa phansi kwesibhakabhaka.
Okudingeka kuqala ukuze kwenziwe izinguquko
Okuyinhloko, futhi, mhlawumbe, isici esinqumayo sezinguquko ezingezinhle ezenzeka kungqimba lomkhathi ngumsebenzi wabantu. Ukuqala kwale nqubo engemihle kungabhekwa njengeScientific and Technological Revolution - ngokunembile isikhathi lapho inani lezimboni nezitshalo landa kakhulu.
Akunakuphikwa ukuthi kancane kancane isimo saya ngokuya siba sibi kakhulu, ngoba inani lamabhizinisi ezimboni lakhula, futhi kanye nalokhu, imboni yezimoto, ukwakhiwa kwemikhumbi nokunye kwaqala ukukhula.
Ngasikhathi sinye, imvelo uqobo iba nomthelela omubi esimweni somkhathi - isenzo sezintaba-mlilo, inqwaba yothuli ezingwadule, eziphakanyiswa ngumoya, nazo zinomthelela omubi ngokwedlulele kungqimba lomkhathi.
Izizathu zokushintsha ukwakheka komkhathi
Cabanga ngezinto ezimbili eziyinhloko ezithinta ukubhujiswa kongqimba lomkhathi:
- i-anthropogenic;
- yemvelo.
Isici esicasula i-anthropogenic sisho umthelela womuntu emvelweni. Njengoba lokhu kuyisici esibaluleke kakhulu, sizobheka kabanzi.
Umsebenzi wabantu, ngandlela thile, uthinta isimo semvelo - ukwakhiwa kwamabhizinisi ezimboni, ukugawulwa kwamahlathi, ukungcoliswa kwemizimba yamanzi, ukulinywa kwenhlabathi. Ngaphezu kwalokho, imiphumela yomsebenzi wayo obalulekile kufanele ibhekwe - ukucubungula imfucuza, amagesi aqeda imoto, ukwakhiwa nokusetshenziswa kwemishini equkethe i-freon, nakho kuyimbangela yokucekelwa phansi koqweqwe lwe-ozone, futhi ngesikhathi esifanayo ukwakheka komkhathi.
Okuyingozi kakhulu ukukhishwa kwe-CO2 emoyeni - yile nto enomphumela omubi ngokweqile hhayi kuphela esimweni semvelo, kepha nasesimweni sempilo yabantu. Ngaphezu kwalokho, kwamanye amadolobha, izakhamuzi ziphoqeleka ukuba zihambe ngezimaski ezikhethekile zokuzivikela ngehora lokugijima - umoya ungcoliswe kakhulu.
Akunakuphikwa ukuthi umkhathi uqukethe okungaphezu nje kwesikhutha. Ngenxa yemisebenzi yezimboni yamabhizinisi, umoya uqukethe ukugcwala komthofu okwandayo, i-nitrogen oxide, i-fluorine namanye amakhemikhali.
Ukugawulwa kwamahlathi emadlelweni nakho kunomthelela omubi ngokwedlulele emkhathini. Ngakho-ke, ukukhuphuka komphumela wokushisa kubangelwa, ngoba ngeke kube khona izitshalo ezithatha i-carbon dioxide, kodwa ezikhiqiza umoya-mpilo.
Umthelela wemvelo
Lesi sici asonakalisi kangako, kepha sisenzeka. Isizathu sokwakhiwa kwenani elikhulu lothuli nezinye izinto ukuwa kwama-meteorites, izintaba-mlilo ezisebenzayo, imimoya ezingwadule. Futhi, ososayensi bathole ukuthi izimbobo zivela esikrinini se-ozone ngezikhathi ezithile - ngokombono wabo, lokhu kungumphumela wokungabi nomthelela omubi womuntu emvelweni kuphela, kepha nasekuthuthukisweni kwemvelo kwegobolondo leplanethi. Ngobulungiswa, kufanele kuphawulwe ukuthi izimbobo ezinjalo ziyanyamalala ngezikhathi ezithile bese ziphinde zakhiwe futhi, ngakho-ke lokhu akufanele kubangelwe yizici ezibucayi.
Ngeshwa, ngumuntu onomthelela omubi emoyeni, angaqapheli ukuthi ngokwenza lokho wenza kube kubi kuye kuphela. Uma ukuthambekela okunjalo kuqhubeka ngokuzayo, imiphumela ingahle ingaqaguleki, kepha hhayi ngomqondo omuhle wegama.
