Imikhiqizo eminingi yengilazi enhle iye yavubukulwa Ezifundeni ZaseNtshonalanga zeShayina yasendulo, ehlehlela emuva eminyakeni engaba ngu-2,000, futhi imikhiqizo yengilazi emidala kunazo zonke emhlabeni ineminyaka engu-4,000 ubudala. Ngokusho kwabavubukuli, ibhodlela lengilazi liyi-artefact egcinwe kakhulu emhlabeni, futhi ayigqwali kalula. Osokhemisi bathi ingilazi iyiwele lesanti, futhi inqobo nje uma isihlabathi sisemhlabeni, ingilazi isemhlabeni.
Kungakhathaliseki ukuthi kungagqwala ibhodlela lengilazi, akusho ukuthi ibhodlela lengilazi alinakunqotshwa ngokwemvelo. Nakuba ingenakucekelwa phansi ngamakhemikhali, “ingacekelwa phansi” ngokomzimba. Umoya namanzi emvelo yizitha zawo ezinkulu.
EFort Bragg, eCalifornia, e-United States, kunolwandle olumibalabala. Uma ungena, ungabona ukuthi yakhiwe amabhola anemibala eminingi. Lawa ma-pellets awawona amatshe ngokwemvelo, kodwa amabhodlela engilazi abantu abawalahlayo. Ngawo-1950, yayisetshenziswa njengendawo yokulahla udoti yamabhodlela ezingilazi alahliwe, kwase kuvalwa indawo yokulahla, kwashiya amashumi ezinkulungwane zamabhodlela ezingilazi asele, ngemva nje kweminyaka engu-60, epholishwa ngamanzi olwandle oLwandlekazi iPacific. bushelelezi futhi iyindilinga.
Eminye iminyaka eyi-100 noma ngaphezulu, ibhishi lesihlabathi sengilazi elimibalabala lizoshabalala, kusho ososayensi. Ngenxa yokuthi amanzi olwandle nomoya wasolwandle kugudla ingilazi, ngokuhamba kwesikhathi, ingilazi iyakhunyulwa ibe yizinhlayiya, bese ilethwa olwandle ngamanzi olwandle, futhi ekugcineni izike phansi olwandle.
Ulwandle olukhazimulayo alusilethi nje kuphela ukuzijabulisa okubonakalayo, kodwa futhi luholela ekucabangeni ngendlela yokuvuselela imikhiqizo yengilazi.
Ukuze uvimbele udoti wezingilazi ekungcoliseni imvelo, ngokuvamile sithatha izindlela zokugaywa kabusha. Njengensimbi egaywe kabusha, ingilazi egaywe kabusha ibuyiselwa esithandweni ukuze incibilike futhi. Njengoba ingilazi iyingxube futhi ingenayo indawo yokuncibilika engaguquki, isithando somlilo sisethelwe kuma-gradients okushisa ahlukene, futhi isigaba ngasinye sizoncibilikisa ingilazi yezingoma ezihlukene futhi sizihlukanise. Endleleni, ukungcola okungafuneki kungabuye kususwe ngokungeza amanye amakhemikhali.
Ukugaywa kabusha kwemikhiqizo yezingilazi ezweni lami kuqale sekwephuzile, futhi izinga lokusetshenziswa licishe libe ngu-13%, lisalele ngemuva kwamazwe athuthukile eYurophu nase-United States. Izimboni ezifanele kula mazwe ashiwo ngenhla sezikhulile, futhi ubuchwepheshe bokugaywa kabusha kanye namazinga afanele ukubhekwa nokufunda ezweni lami.
