Hariho umugani uzwi mubushinwa. Kera, hariho igihangange cyitwa kuafu cyashakaga gusiga izuba inyuma kikazana umucyo mwisi iteka ryose.Kuko yari yegereye izuba cyane, yari afite inyota.Niba ashaka kunywa amazi, yagiye ku ruzi rw'umuhondo n'umugezi wa weishui kunywa amazi. Umugezi w'umuhondo, amazi ya weishui ntabwo uhagije, kuafu yagiye mu majyaruguru kunywa amazi y'ikiyaga kinini.Ariko mbere yuko agera ku kiyaga , yapfuye azize inyota. Asize inkoni ye gusa, ahinduka igiti cyamashaza.Gufasha abamuri inyuma bamukunda birukana urumuri.

Binyuze muri iyi nkuru dushobora kumenya akamaro k'izuba kuri twe, nubwo iyi nkuru idasobanutse, ariko imico irasobanutse kandi yimbitse.Nubwo iterambere rikomeje guteza imbere siyanse n'ikoranabuhanga ku isi, abantu basaba ko ubuzima butandukanye bugenda bwiyongera, kandi iterambere ryumutungo kamere naryo rirakomeje.Tugomba kumera nka kuafu, urukundo nyarwo rwizuba, gukoresha cyane izuba bituruka kumirasire yizuba yingufu, kugirango twirukane ibidukikije byumucyo neza.

Hamwe n'ubuke bw'umutungo w'isi ugenda wiyongera, ikiguzi cy'ishoramari cy'ingufu z'ibanze kiriyongera, kandi ingaruka zitandukanye z'umutekano ndetse n’umwanda zirahari hose.

Itara ryizuba rihinduka amashanyarazi akoresheje imirasire yizuba. Mugihe cyumunsi, ndetse no muminsi yibicu, iyi generator yizuba (izuba ryizuba) ikusanya kandi ikabika ingufu zikenewe.Niyo mpamvu, izuba ritanga ingufu, zikoreshwa mugutanga amashanyarazi.

Imirasire y'izuba ningufu zibanze kandi zishobora kuvugururwa.Bikungahaye mubutunzi, kubuntu bwo gukoresha, nta traffic, ibidukikije bidafite umwanda.Kugira ngo habeho ubuzima bushya kubantu, kugirango societe nabantu mubihe byingufu kubungabunga, kugabanya umwanda.

Fata urugero rw'amatara yo gushushanya izuba, kubera kurengera ibidukikije bibisi, gukora neza no kuzigama ingufu, umucyo mwinshi, ubuziranenge, ubuzima burebure, umutekano mwinshi, ubworoherane, ubwenge buhanitse, nibindi. Abantu benshi bakunda amatara yizuba yo hanze

Kurengera ibidukikije ntabwo ari iby'umuntu cyangwa igihugu, ahubwo bireba isi yose.Ubwiza bwabantu kwisi yose buratera imbere, bityo imyumvire yiterambere ryingufu zizuba zashinze imizi mumitima yabantu.Twese turi abarinda ibidukikije bibisi, ntabwo abiteza imbere bahumanya ibidukikije.
