Apho kukho ukwangowona mmandla unomthamo omkhulu ebomini komhlaba? Ukususela oko mninzi ubomi buxhomekeke?

Apho kukho ukwangowona mmandla unomthamo omkhulu ebomini komhlaba? Izazinzulu, zokuma ziye isonjululwe elide le ngxaki umdla. Sicela ukuba ufumane impendulo yalo mbuzo umdla kweli nqaku ngokufundisayo.

Ingxinano uhlala phezu komhlaba

Mhlawumbi akukho mfihlelo labemi kumphezulu iplanethi yethu akuxhomekekanga lonke ezisasaziweyo. Ukuze ube ngqo, oko yokungalingani. Kunzima ukukholelwa, kodwa ezintlanu kuphela epesenti Umhlaba likhaya malunga-70% yabo bonke abemi kulo mhlaba.

Ukuze nombono apho kwelo lizwe kukho ukwangowona mmandla unomthamo omkhulu ebomini, khangela nje ikhadi ehambelanayo. Basenze zejografi, inguqu isixa esikhulu ulwazi oluyinyaniso ngendlela iingenelo ngokwaneleyo capacious kwaye lula baqonda.

Imephu eendawo, nto leyo ebonisa ngokucacileyo lexinene ubomi emhlabeni. Yenziwe ngu ebizwa ngokuba indawo yolwamkelo, xa ukusasazwa lwesithuba ebonakalayo necacileyo, inkqubo kuboniswa amachaphaza. Kulo mzekelo, ngamachaphaza ziyatyeba eshicilelweyo - i indawo enabantu abaninzi.

Population mninzi - ntoni na?

Ukuxinana (okanye ingxinano) labantu - sisalathisi inqanaba yabemi ummandla othile. Eli linani kubemi abahlala kummandla unit. Oku kungabalelwa lonke womhlaba, kwakunye kumazwe ngamnye okanye kwiindawo ezincinane. Zokuma ukulinganisa lexinene ubomi umhlaba kwi indlela yokubala elula:

Population mninzi = inani labantu / indawo kwintsimi ethile.

Oku ulinganiswa abemi ^{km2 nganye.}

Ukuza kuthi ga ngoku, lexinene yabemi-langa - abantu malunga-40 / km ^2. Ngelo xesha linye i-Ubuninzi babantu ngaphakathi zokuhlala ezidolophini e amashumi amaxesha ngaphezulu kwiindawo ezisemaphandleni.

Ukuxinana labemi kwenzekayo kwixesha elidluleyo

Njengoko ababhali-mbali yabantu bathi, namawaka-10 kwiminyaka eyadlulayo waphila emhlabeni yethu abantu abazizigidi ezintlanu kuphela. Nangona bonke belimiwe amazwekazi, kodwa loxinano iyonke labantu liphantsi kakhulu. Kamva, kunye nophuhliso yoluntu, isixeko yaqala ukuvela, ebe eziba ukuzikisa ingqondo yoluntu. Around kubo Bakha ibhanti yezolimo kunye nabalimi predobladaniem ukuvelisa ukutya abantu ezidolophini.

Kunikezo yoluntu kule planethi iphenjelelwa ngamandla kakhulu ekuthiwa- Industrial Revolution, eyaqala eBritani ngenkulungwane XVIII emva kwexesha. Abahlali baqala ukugxila kwiindawo mveliso. Ngelo xesha kukho amazwe esebenzayo of America ngu baseYurophu (i-World Entsha).

Eyona ezisemqoka zokusabalalisa labantu

Kufuneka kuqatshelwe ukuba lexinene zidalwa zikrelekrele kuxhomekeke eziliqela izinto zendalo kunye noqoqosho. Zezi:

• iimeko zemozulu (eyona ndawo inabantu izowuni sezulu sifudumele sabutropikhi);
• ukukhululeka (inkoliso yabantu ehlabathini buzinze amathafa, nezihlambo);
• ukufikelela kwi olwandle (kwimimandla yonxweme, njengoko umthetho, esinabantu kakhulu abantu);
• ubukho umlambo okanye umzimba yamanzi imithombo yamanzi amatsha;
• inqanaba lophuhliso ishishini wezibonelelo zothutho lizwe, (eli njengenqobo iye ebonakalayo ukususela ekuqaleni kwenkulungwane XIX).

Apho kukho ukwangowona mmandla unomthamo omkhulu ebomini komhlaba?

Enyanisweni, onke amazwekazi planethi (ngaphandle, mhlawumbi, Antarctica) kufuneka iimeko zabemi yokuhlala isigxina. Noko ke, "intlanzi ukhangela apho gangqa, kwaye umntu -. Kokona kulungileyo" Ngoko ke, 50% yomhlaba koMhlaba likhaya akukho ngaphezulu kwe-5% abemi balo.

Ummandla kakhulu enabantu abaninzi ehlabathini uthathwa mpuma Asia. Kukho kuqwalasele malunga-30% yabo bonke abemi kulo mhlaba. Ummandla wesibini kwenani labantu square kilometre ingabizwa Western Europe.

Ubuninzi babantu nkqu nangaphakathi lizwe linye ziyahluka kakhulu. Thelekisa umzekelo UK: kwimimandla weentaba Scotland, eli nani bantu hayi ngaphezulu kwe-10 / km ^2, lo gama kumbindi London - malunga nama-20 000 km ^2!

Xa sihlalutya lexinene yabemi ithi ngamnye, amazwe ezikhokelela kwesi salathisi zezi:

• i seLizwe Monaco (abantu 16620 / km ^2);
• Singapore (abantu 6389 / km ^2);
• Vatican (abantu 2093 / km ^2);
• Malta (abantu 1261 / km ^2);
• Maldives (1163chel / km ^2);
• Bangladesh (abantu 1005 / km ^2).

City-ziintshatsheli kwi ukwanda kwabantu

Eli nani likhulu imizi bebekelwa eYurophu, eMntla Melika, kwaye kananjalo naseziqithini Japanese. Nathi sinishumayeza top izixeko ezilishumi kwehlabathi kunye noxinano lwabantu oluphezulu:

1. Shanghai (China)
2. Karachi (Pakistan)
3. Istanbul (Turkey)
4. Tokyo (Japan)
5. Mumbai (India)
6. Buenos Aires (Argentina)
7. Nhlokomhaka (Bangladesh)
8. Manila (Philippines)
9. Delhi (India)
10. EMoscow (Russia)

isiphelo

Ngoko uyazi impendulo yalo mbuzo apho nomhlaba apho mmandla unomthamo omkhulu owohlukeneyo ebomini. Ngenxa yoko, inani labantu kumphezulu womhlaba sinikwa bengaphuhlanga ngokulinganayo kakhulu, nobuninzi yayo ixhomekeke ezahlukeneyo izinto zendalo, ezoqoqosho kunye nembali.
