Bangaki abantu emhlabeni futhi lokho kuncike

Umbuzo of interest inani elikhulu labantu, kusukela ezinganeni kuya abantu ubudala: "abantu Bangaki emhlabeni?" Yiqiniso, ukuphendula ngobuciko ngokuphelele akunakwenzeka, njengoba njalo ngomzuzu umuntu ezalwa emhlabeni, futhi umuntu efa. Kulinganiselwa ukuthi ngo-2012, wazalelwa abantu semimilliardny Emhlabeni esaphila namuhla, Ngakho-ke, impendulo yombuzo othi abantu abaningi kanjani emhlabeni manje - angaphezu kwezigidi eziyizinkulungwane eziyisikhombisa.

Umlando omncane

Iminyaka eyizinkulungwane ezingamashumi amane ngaphambi kwesikhathi sethu esivamile, wazalwa cishe amane billion no iminyaka 1990, mayelana nanhlanu bhiliyoni. Ngo-1900, izwe elingabafanele bona abantu abangaphezu kwezigidi eziyizinkulungwane ezimbili, futhi ngo-1950 engaphezu kwemibili nengxenye, ngo-2005 - engaphezu kwemihlanu. Njengoba singabona, labantu laqala ukukhula ngokushesha engu-120 kuphela edlule.

Yini enquma abantu abaningi kanjani emhlabeni

Phakathi kubhubhane izifo futhi wafa isibalo esikhulu sabantu. Ngokwesibonelo, isifo 1352 kuya 1346 GG nesifo sezimbilapho, isifo omkhulu, omnyama ukufa - kangaka okuthiwa yilesi sifo esesabekayo. It phephetha ingxenye yesine ka inani labantu emhlabeni. Black ingxibongo - ezivela kuye esefa engamakhulu aphume abantu abangaba yizinkulungwane eziyikhulu. Lesi sifo engawayekanga ubani. Ukugqashuka kwaphela ngemva ngokugoma. Acute ukutheleleka emathunjini - ikholera - Kushone abantu abangaphezu kwezigidi ezingu-amane nantathu. Fever, ephelezelwa sokuphazamiseka kwengqondo ubuso imfiva, eyayibangela ukuphila abangaphezu kwezigidi ezintathu. Umalaleveva, udenga ne- imfiva ngonyaka afe kuze kube abantu abayizigidi ezintathu. AIDS wadlulisela ukuphila angaphezu kwamashumi amane million, "inhlupho we kwekhulu lamashumi amabili nanye" - igama lesibili igciwane. Sibona abantu abaningi emhlabeni baye bafa futhi uqhubeke babulawa yizifo ezihlukahlukene.

izinqubo yokuhlanzeka ukuba zenzeka ekhulwini lamashumi amabili, iningi labantu azinakwa. Ngenxa yalokho, ukuthuthukisa izifo, esibuthaka sokuzivikela ezifweni, futhi linciphisa ukuphila okulindelekile. izicebi kuphela angasebenzisa insipho. Labo abasaya walandela nokuhlanzeka (babembalwa), kodwa asikwazanga ukuthenga insipho, basebenzisa izindlela ezihlukahlukene liqueurs nomlotha yokuhlanza.

Ukuswelakala kokusebenza ngokuhlanganyela izidakamizwa futhi kwathinta bangaki abantu ku iplanethi enguMhlaba siphile. Ama-antibiotic, le elwa namagciwane eziqine, wavula ngo-1928 u-Alexander Fleming. Ngenxa yalesi ukutholakala yena yanikezelwa uMklomelo KaNobel. Kamuva beza ejenti antifungal, futhi elwa namagciwane. Manje singaya ikhemisi futhi uthenge eziningi izidakamizwa, kodwa ngemva kwamakhulu kuphela edlule, okhokho bethu kwakungatholakala kuphela ziphathwe amakhambi, futhi ngisho nangalesosikhathi ngaso sonke isikhathi.

Medicine uye wagxumela phambili: ukuhlinzwa, isitho ukufakelwa, ukuvela izidakamizwa ehlukahlukene ukusekela izitho - konke lokhu sekunyuse isilinganiso sobude bokuphila sabantu.

Phakathi kumiswa isimo bekulokhu eziningi izimpi insimu. Phakathi neMpi Yezwe II zabulala abantu abangaphezu kuka amahlanu million kuqala - angaphezu kwezigidi ezingu amabili nanhlanu. Kuwo wonke umlando planethi Usanda kuphumelela izimpi mayelana 15,000 futhi zabulala abantu abangaphezu kuka ezintathu nengxenye bhiliyoni.

kungakanani bezalwa kanjani abantu emhlabeni eziningi, futhi kuncike ngokuqondile. Omunye namashumi amahlanu edlule, ngaba abayisikhombisa abafa ngayinye izinsana eziyishumi. Njengoba sekunama-izibhedlela womama, onekhono ukunakekelwa odokotela ukufa kwezinsana siye sehla ngeminyaka izinkulungwane zezikhathi.

Zonke lezi zici yathonya futhi siqhubeke nomthelela isibalo sabantu emhlabeni. Ngokwe abacwaningi sona sabikezela ukuthi ngo 2050 iplanethi kuyoba abantu abangaphezu kwezigidi eziyizinkulungwane nanye.
