Abantu abaningi cishe abazi okuningi ngomhlaba ongavamile, futhi abazi ukuthi umhlaba ongavamile usuphenduke kanjani insiza enamasu eqhathaniswa nowoyela.
Ukukubeka kalula, umhlaba ongavamile uyiqembu lezakhi zensimbi ezijwayelekile, eziyigugu kakhulu, hhayi nje ngoba izinqolobane zazo ziyindlala, azivuseleleki, kunzima ukuzihlukanisa, ukuzihlanza nokucubungula, kodwa futhi ngoba zisetshenziswa kabanzi kwezolimo, izimboni, ezempi kanye nezinye izimboni, okuwusekelo olubalulekile lokwenziwa kwezinto ezintsha kanye nensiza ebalulekile ehlobene nokuthuthukiswa kobuchwepheshe bezokuvikela bukazwelonke obusezingeni eliphezulu.

Embonini, umhlaba ongavamile "uvithamini".Idlala indima engenakuthathelwa indawo emkhakheni wezinto ezifana ne-fluorescence, uzibuthe, i-laser, ukuxhumana kwe-fiber optical, amandla okugcina i-hydrogen, i-superconductivity, njll. Ngokuyisisekelo akunakwenzeka ukuvala umhlaba ongavamile ngaphandle uma kunobuchwepheshe obuphezulu kakhulu.
-Ngokwezempi, umhlaba ongavamile "ungumgogodla".Njengamanje, umhlaba ongavamile ukhona cishe kuzo zonke izikhali zobuchwepheshe obuphezulu, futhi izinto zomhlaba ezingavamile ngokuvamile zitholakala emnyombweni wezikhali zobuchwepheshe obuphezulu.Isibonelo, umcibisholo we-Patriot e-United States wasebenzisa cishe amakhilogremu angu-3 wezibuthe ze-samarium cobalt kanye nozibuthe bensimbi be-neodymium boron ohlelweni lwawo lokuqondisa lwe-electron beam egxile ekubambeni ngokunembile imicibisholo engenayo.I-laser rangefinder yethangi le-M1, injini ye-F-22 i-fighter kanye ne-fuselage ekhanyayo neqinile konke kuncike emhlabeni ongavamile.Owayeyisikhulu sezempi sase-United States waze wathi: “Izimangaliso zempi ezimangalisayo eMpini YaseGulf nekhono lokulawula i-United States ngokulinganayo ezimpini zendawo ngemva kweMpi Yomshoshaphansi, ngomqondo othile, umhlaba ongavamile owenze konke lokhu kwenzeke.

—— Umhlaba ongavamile ukhona “yonke indawo” ekuphileni.Isikrini somakhalekhukhwini wethu, i-LED, ikhompuyutha, ikhamera yedijithali … Iyiphi engasebenzisi izinto zomhlaba ezingavamile?
Kuthiwa njalo ngobuchwepheshe obusha obune obuvela emhlabeni wanamuhla, obunye babo kumelwe buhlobane nomhlaba ongavamile!
Ngabe umhlaba ungaba njani ngaphandle komhlaba ongavamile?
I-Wall Street Journal yase-United States ngo-September 28, 2009 yaphendula lo mbuzo-ngaphandle komhlaba ongavamile, ngeke sisaba nazo izikrini ze-TV, ama-hard disk ekhompyutha, izintambo ze-fiber optic, amakhamera edijithali kanye nemishini eminingi yokuthwebula yezokwelapha.Umhlaba ongavamile uyisici esakha omazibuthe abanamandla.Bambalwa abantu abazi ukuthi omagnethi abanamandla bayisici esibaluleke kakhulu kuzo zonke izinhlelo zokujikisa imicibisholo ezitokisini zokuzivikela zase-US.Ngaphandle komhlaba ongavamile, kufanele uvalelise ekuqalisweni komkhathi nesathelayithi, futhi uhlelo lokucwenga uwoyela emhlabeni wonke luzoyeka ukusebenza.Umhlaba ongavamile uwumthombo wamasu abantu abazowunaka kakhulu esikhathini esizayo.
Inkulumo ethi “kukhona uwoyela eMpumalanga Ephakathi kanye nomhlaba ongavamile eShayina” ibonisa isimo semithombo yomhlaba engavamile yaseChina.
Uma ubheka isithombe, izinqolobane zezimayini zomhlaba eziyivelakancane eChina zimane nje “zigibele uthuli” emhlabeni.Ngo-2015, iziqiwi zaseShayina eziyivelakancane bezingamathani ayizigidi ezingama-55, okubalelwa ku-42.3% wesamba seziqiwu emhlabeni, okungesokuqala emhlabeni.I-China futhi ukuphela kwezwe elingahlinzeka ngazo zonke izinhlobo ezingu-17 zezinsimbi zomhlaba eziyivelakancane, ikakhulukazi umhlabathi osindayo ongavamile osetshenziswa kakhulu empini, futhi iShayina inesabelo esikhulu. ngaphezu kwama-90% ezinqolobane zomhlaba eziyivelakancane e-China.Uma kuqhathaniswa nezwe laseShayina elinamandla okuzenzela kulo mkhakha, nginovalo lokuthi ngisho i-Organisation of Petroleum Exporting Countries (OPEC), ephethe u-69% wohwebo lukawoyela emhlabeni, izokhala.

Izizinda kanye nokukhiqizwa kwezimayini zomhlaba ezingavamile eShayina akufani kakhulu.Kusukela kulesi sibalo esingenhla, nakuba i-China inezindawo zokugcina umhlaba ezingavamile, isekude ekubeni "ikhethekile".Kodwa-ke, ngonyaka wezi-2015, ukukhiqizwa kwezimbiwa zomhlaba ezingavamile emhlabeni wonke kwaba amathani ayi-120,000, lapho i-China yanikela ngamathani ayi-105,000, okubalelwa ku-87.5% womkhiqizo ophelele womhlaba.
Ngaphansi kwesimo sokungahlolisisi okwanele, umhlaba ongavamile okhona emhlabeni ungambiwa cishe iminyaka eyinkulungwane, okusho ukuthi umhlaba ongavamile awutholakali kangako emhlabeni.Umthelela waseShayina emhlabeni jikelele ongavamile ugxile kakhulu ekukhiqizweni kunezindawo ezizibekelelayo.
