Immisa qof ayaa dunida oo dhan ayaa iyo rabitaankii

oo daqiiqad kastana dhulka qof dhinto ama u dhashay. Sababtoo ah in la sheego inta qof ee dunida haatan ku nool xaq, xilligan, waa wax aan macquul aheyn. Inkastoo lacagta qiyaas aasaasay. Xitaa abuuray script ah - robot gaar ah si ay u xisaabiso tirada dadka on Earth la joogo. Markii la weydiiyay dadka sida badan on Earth nool January 2014, wuxuu mas'uul ka yahay - 7189000000 Tani waxaa xaqiijiyay by the xisaabaha statistics casriga ..

Marka qof ayaa bartay in ay ka fekeraan, xisaabin iyo qori, uu doonayo in uu tirin dadka iyo loo ogaado dadka sida badan on Earth. Xataa xilligii ilbaxnimada aan fuliyay xisaabin ugu horeysay. Waxaanu u sameeyey awoodaha si loo xakameeyo lacagta canshuurta. Waxaa loo tixgeliyaa dadka magaalada, gobolka, dalka. Tirakoobka horumariyo adag oo gaabis ah. Demographers odhan waa in dunidu ku noolaa a bilyan ka badan qarnigii 19aad. Number mar kale qiyaas. All tirooyinka ku saabsan dadka ku salaysan xisaabta iyo fikradahaaga. In ka badan laba qarniyo soo dhaafay, koror ah 600%, taas macnaheedu waa in ka badan 6 bilyan. Si kastaba ha ahaatee, tirooyinkan la xidhiidhaan dalalka ilbaxnimada, halkaas oo bacriminta waa la tixgeliyaa. Imisa qof oo ku nool dunida oo run ahaantii waa adag tahay in la yidhaahdo.

Xogta ugu horeysay ka badan ama ka yar saxda ah ayaa la helay sannadkii 1960, ka dib markii tirakoobka dadka, inta badan dalalka. Maanta tiradaasi ayaa dhaafto 7 billion. Iyo sida loo heli? By ku daray ilaa tirada dadka ka yimid dalalka kala duwan. Si kastaba ha ahaatee, haddii ay gobol kasta khuseysaa la mas'uuliyada buuxda ee tirakoobka? Tusaale ahaan, dal sida Ukraine, sida Yurub iyo ilbaxnimada, saddex jeer hore u xanbaarsan yahay tirakoobka ay sabab u tahay dhaqaale la'aan. Statisticians ay sheegayaan in kaliya tiro yar oo dadka lagu tiriyaa sheegin. Wixii la'aanta wax ka wanaagsan aynu u leeyihiin in ay ku heshiiyaan.

Su'aashu waxay tahay, sida dad badan oo dunida ku dhashay taariikhda aadanaha, 2008 ayaa loo magacaabay ugu xiiso leh oo dhan, soo jeediyay by majaladda caan ah "Quest". saynisyahano badan oo ay ka shaqeeyeen waxa on, oo helay noocyo kala duwan oo tirooyinka.

Haddii aad qaadato xogta this, hadda deggan meeraha waa% ka mid ah kuwii hore ku noolaa oo keliya 6. Xisaabinta waxaa la sameeyaa iyadoo 50 000 BC. e., dhalashada of sapiens homo. Muddo sannad n 1aad. e. dunida oo dhan ayaa ku nool 300 oo milyan oo qof. In 1650 th dadka gaaray nus bilyan ah, iyo in qarnigii 19 - billion a.

Sida ay dadka badan ee adduunka maanta, aynu hore u garan. Sidaa darteed, ee taariikhda tirada guud ee dadweynaha ee meeraha Earth waa 108 bilyan oo qof. Waxaa soo baxday in dictum hadda iminka of Romans qadiimiga ah tegey dunida kale: ". Waxa uu u baxay si ay inta badan"

Seynisyahanno soo jeedinaynaa in 2025 dunida yeelan doonaa in ka badan 8 bilyan oo qof, iyo in 2050 -. 9.7 billion inkasta oo oo dhan saadaasha ba'an ku saabsan mustaqbalka, waxaan doonayaa in aan aaminsanahay in aadanaha, muujiyaan horumarka dhan ah margin weyn ammaanka aan maaanka khayraadka.
