Ingqikithi Yokuphila: Amanzi

Amanzi ayinsika yokuphila, isincibilikisi esitholakala emhlabeni wonke esibalulekile kuzo zonke izinhlobo zezinto eziphilayo ezaziwayo. Ukubaluleka kwawo kudlulela ngalé kokufakwa emanzini nje emanzini; iyisisekelo sezinqubo zebhayoloji, ukusimama kwemvelo, ngisho nendawo yonke ebanzi.

Iqhaza Lamanzi Empilweni

Emkhakheni wezinto eziphilayo, amanzi abalulekile. Yakha ingxenye enkulu yomzimba womuntu—cishe ama-60%—futhi idlala indima ebalulekile emisebenzini ehlukahlukene yomzimba. Kusukela ekulawuleni izinga lokushisa lomzimba ngokujuluka kuya ekusizeni ukusabela kwamakhemikhali e-biochemical njengendlela yokwenza ama-enzyme, amanzi abalulekile ekugcineni i-homeostasis. Izinqubo zamaselula, okuhlanganisa ukuthuthwa kwezakhi, ukukhishwa kwemfucuza, kanye nokuhlanganiswa kwamaprotheni ne-DNA, kuncike kakhulu emanzini.

Ukubaluleka Kwezemvelo

Ngalé kwezinto eziphilayo ngazinye, amanzi abumba imvelo nesimo sezulu. Izimiso zamanzi ahlanzekile njengemifula, amachibi namaxhaphozi zisekela izindawo zokuhlala ezihlukahlukene futhi zibalulekile ukuze kuphile inqwaba yezinhlobo zezinto eziphilayo. Amanzi aphinde abe nomthelela esimweni sezulu kanye nokulawulwa kwesimo sezulu. Umjikelezo wamanzi, ohlanganisa ukuhwamuka, ukufiphala, ukuna, nokungena emanzini, usabalalisa kabusha amanzi emhlabeni wonke, uqinisekisa ukuthi imvelo ithola umswakama odingekayo.

Ukushoda Kwamanzi Nezinselele

Naphezu kobuningi bawo, amanzi ahlanzekile awumthombo olinganiselwe. Ukuntuleka kwamanzi kuthinta izigidigidi zabantu emhlabeni wonke, okusongela impilo, ezolimo, nokuzinza kwezomnotho. Izinto ezinjengokushintsha kwesimo sezulu, ukungcola, nokukhipha amanzi ngokweqile kuqeda amanzi futhi kuphazamise imvelo. Ukubhekana nalezi zinselele kudinga izindlela zokuphatha ezisimeme, imizamo yokonga, kanye nokuqanjwa kabusha kwezobuchwepheshe ukuze kuqinisekiswe ukutholakala kwamanzi ahlanzekile ngokulinganayo.

Amanzi kanye neCosmos

Ukubaluleka kwamanzi kudlulela nangale koMhlaba. Ukufuna ukuphila kwamanye amazwe kuvame ukugxila ezintweni zasemkhathini ezinamanzi, njengoba ukuba khona kwawo kungase kubonise ukuthi kungenzeka kuhlale kuphi. Kusukela ku-Mars kuya ezinyangeni ezineqhwa zeJupiter neSaturn, ososayensi baphenya lezi zindawo ukuze bathole izimpawu zamanzi awuketshezi, ezingase zisekele ukuphila ngale kweplanethi yethu.

Isiphetho

Amanzi angaphezulu nje kwento engokoqobo; iwumgogodla wokuphila uqobo. Ukuba khona kwayo kuwubufakazi bokuxhumana kwezinhlelo zebhayoloji, izimiso zemvelo, ngisho nezigigaba zendawo yonke. Njengoba sizulazula ezinkingeni zokulawulwa nokongiwa kwamanzi, kubalulekile ukuqaphela nokuhlonipha indima ebalulekile edlalwa amanzi ekusimamiseni ukuphila nasekulolongeni umhlaba wethu.
