Kudziya kwepasi pose kuri kukonzera kuti chando cheplar chinyunguduke uye Izvi zvinokonzeresa kukwira kwemwero wegungwa. Kune akawanda maguta emahombekombe ayo, kana mwero wegungwa ukaramba uchikwira, vanozosara vasina chero mahombekombe. Vanhu vanofanirwa kufamba kana kutamira kune dzimwe nzvimbo nekuda kwekukwira kwenzvimbo yegungwa kana zvimwe zvikonzero zvine chekuita nekuwedzera kwehuwandu uye kusimba kwezviitiko zvemamiriro ekunze zvakanyanya (senge madutu, mafashama, kusanaya kwemvura ...) vanonzi vapoteri vemamiriro ekunze.
Inofungidzirwa kuti panosvika gore ra 2100, vamwe vanhu mabhiriyoni maviri (ichi chichava chikamu chimwe muzvishanu chevagari vepasi panguva iyoyo) vanogona kuve vapoteri vemamiriro ekunze, kunyanya nekuda kwekukwira kwenzvimbo yemakungwa.
Shanduko yemamiriro ekunze uye vapoteri
Mamirioni nemamirioni avanhu vanogara mumaguta emahombekombe ayo ari kuwedzera kutyisidzirwa nezviitiko zvakanyanyisa zvemamiriro ekunze senge madutu, mafashama, uye kukwira kwenzvimbo dzegungwa dzinokonzerwa nekuchinja kwemamiriro ekunze. Vanhu ava vane hupenyu hwavo, mhuri, shamwari, basa uye zvichingodaro, vanomanikidzwa kuenda kune dzimwe nzvimbo dzakachengeteka uye dzinogaramo zvemukati kwenguva yakareba.
Chidzidzo chakaitwa paCornell University iyo inoti isu tichava nevanhu vazhinji munyika ine nzvimbo shoma uye kuti izvi zvichaitika nekukurumidza kupfuura zvatinofunga.
Nekukwira kwemwero wegungwa, vanhu vese vanogara munzvimbo dzemahombekombe vanofanirwa kutamira kunzvimbo dzakachengeteka mukati menyika. Kune rimwe divi, huwandu hwepasi rose huri kungokura gore rega rega. Saka zvese izvi zvinotungamira mukugara nevanhu vazhinji munzvimbo isingagarike.

Uye zvese izvi zvinotungamira kuti vanhu vatarise nzvimbo nyowani dzekugara.
Zvinenge, 2.000 bhiriyoni vanhu vanogona kuve vapoteri vemamiriro ekunze ne2100. Iwo anodhumhana masimba ekubereka kwevanhu, kunyudza nzvimbo dzemahombekombe, kudzoka kwekugara uye zvipingaidzo zvekugarisa mukati megungwa idambudziko rakakura.
