Nthawi zambiri, mudzi wonse anasiya malo bwino ndipo anapita kudziko lachilendo kwa pofufuza mavuto. Katswiri m'mayiko ena saloledwa kukhala nyama husbandry ndi ulimi. mofulumira kwambiri chinawonjezeka ndi chiwerengero cha anthu onse padziko lapansi. Ngati zaka 15,000 zapitazo Earth panali pafupifupi 3 miliyoni anthu, tsopano chithunzi uli woposa biliyoni 6. Anthu ambiri amene akukhala mu madera a m'zigwa alili. Iwo yabwino unagawanika munda, kumanga mafakitale ndi zomera, kukhala m'midzi.

Pa dziko lapansi mbali zinayi tingaone kumene resettlement wa anthu yowirira kwambiri. Ndi kumadzulo kwa Ulaya, South ndi Asia East, kum'mawa North America. Kuchita izi, zifukwa zawo: yabwino zinthu zachilengedwe, nthawi ya Pamudzi ndi chitukuko cha chuma. Mwachitsanzo, anthu Asian akadali mwachangu seeded ndi yothiriridwa dothi. Yabwino nyengo amalola kuti kusonkhanitsa zokolola zochepa chaka kudyetsa banja lalikulu.

Mu Ulaya ndi North America chimakhala chogwidwa ndi kuthetsa m'tawuni. Ndi bwino kwambiri anayamba zomangamanga, anamanga kwambiri za mafakitale ano, makampani umalamulira ulimi.

ntchito zachuma

ntchito zachuma zimakhudza chilengedwe ndi kumasintha. Ndi kumabungwe osiyanasiyana anakhudzidwa ndi chikhalidwe m'njira zosiyanasiyana.

Choncho, ulimi anali wochititsa kuchepetsa m'madera dziko kumene zinthu zachilengedwe ikutsatiridwa. Kwa minda ndi msipu zofunika kwambiri danga, kudula nkhalango, nyama anataya malo awo. Chifukwa cha zonse katundu dothi pang'ono wotaya chonde zidazo. Amapanga ulimi wothirira amalola kuti kukolola, koma njira imeneyi ali ndi zovuta zake. Choncho, mu zigawo louma a dziko lapansi madzi kwambiri kungachititse kuti amenewa ake ndi kuchepetsedwa mbewu. Ziweto kupondaponda zomera ndi nthaka ting'onoting'ono basi. Nthawi zambiri louma msipu nyengo kuwasandutsa chipululu.

Makamaka zovulaza chilengedwe kukula mofulumira mafakitale. Olimba ndi madzi zinthu umalowa mu nthaka ndi madzi, ndi mpweya anamasulidwa mu mlengalenga. Kwafalikira a mizinda m'pofunika chitukuko cha madera atsopano kumene zomera waonongeka. kuwonongeka kwa malo zedi limakhudza anthu thanzi la anthu.

kufufuza lapansi anthu: dziko

Anthu amene amakhala mu gawo lawo, ndi chinenero ndi chikhalidwe chimodzi, mtundu mawonekedwe. Chingakhale mtundu, fuko, anthu. M'mbuyomu, anthu kwambiri mtundu kulenga chitukuko lonse.

Panopa dziko pali mayiko oposa 200. Iwo onse zosiyana kwa wina. Pali mayiko amene zatenga ndi kontinenti lonse (Australia), ndipo alipo ndithu ting'onoting'ono wopangidwa mwa mzinda wina (Vatican). m'mayiko osiyanasiyana komanso anthu. Pali biliyoni limati (India, China), ndipo pali anthu amene mumakhala zoposa zikwi zingapo (San Marino).

Choncho, kuganizira funso mmene anali chitukuko cha munthu lapansi, Ndizachidziwikire kuti ndondomeko imeneyi siinamalizidwe, ndipo tidzaphunzira zambiri zosangalatsa zambiri za dziko lapansi.
