00:00.765 --> 00:06.750
Ezinkundleni zezindaba, ukulawulwa kwesimo sezulu
kuvame ukuboniswa njengombono wobuqili ohlekisayo.

00:06.750 --> 00:12.660
Kodwa-ke, kungani izikhungo zamalungelo obunikazi
zikwazile ukunikeza amalungelo obunikazi amaningi kangaka

00:12.660 --> 00:16.702
okuguqulwa kwesimo sezulu eminyakeni eyikhulu edlule?

00:16.702 --> 00:20.100
Ukuze kucace amaqiniso kusukela ekuqaleni:

00:20.100 --> 00:29.007
Iphatenti ilungelo lezimpahla zemboni lokusungula
lobuchwepheshe, elinika umnikazi ilungelo eliyingqayizivele

00:29.007 --> 00:34.140
lokukhiqiza umkhiqizo noma ukwenza inqubo iminyaka engu-20.

00:34.140 --> 00:39.618
Ukuze ilungelo lepropathi
linikezwe, kuqala kuhlolwa ukusebenza kwalo.

00:39.618 --> 00:45.156
Nakuba umthetho wamapatenti waseMelika uhluke
kumthetho waseYurophu ngezici ezimbalwa

00:45.156 --> 00:49.419
ezibalulekile, womabili ugcizelela kakhulu ukusebenza.

00:49.419 --> 00:55.586
Lokho kubandakanya amaqiniso ayisisekelo mayelana namalungelo
obunikazi, ngaleyo ndlela namalungelo obunikazi bemozulu.

00:55.586 --> 01:02.625
Kulo hlelo, sikwethula elinye lamapatenti esimo
sezulu amadala kakhulu asenokubaluleka namuhla: .

01:02.625 --> 01:09.942
Eminyakeni emibili ngemuva kweMpi Yezwe Yokuqala,
eminyakeni engaphezu kuka-100 edlule, iphatenti US1338343A

01:09.942 --> 01:14.447
yabhaliswa kuJules Verdier, unjiniyela owayehlala eFrance.

01:14.447 --> 01:20.056
Inqubo ayithuthukisile yenza kwaba nokwenzeka ukudala amafu
enziwe ngabantu, intuthu noma umusi ngokuwahlukanisa

01:20.056 --> 01:25.962
abe yizicucu ezincane kakhulu ama-anhydrous chlorides
afana ne-titanium chloride noma i-stannous chloride.

01:25.962 --> 01:37.702
Ngo-1924, 1936, 1937 no-1941, kwabhaliswa eminye
amapatenti okukhiqiza nokusabalalisa intuthu nemimoya emanzi.

01:37.702 --> 01:41.579
Lapho iphatenti yokuqala yokukhiqiza
intuthu ifakwe ngaleso sikhathi, abantu

01:41.579 --> 01:44.594
mhlawumbe babe nezinye izintshisekelo engqondweni.

01:44.594 --> 01:49.808
Namuhla, ngezizathu ezithi zokuvikela imvelo, kunentshisekelo
yokwenza ilanga libe mnyama ukuze kuncishiswe

01:49.808 --> 01:56.760
ukufudumala komhlaba, kodwa futhi nokudala amafu enziwe
ngabantu noma ngisho nengqimba yamanzi emoyeni kanye nomusi.

01:56.760 --> 02:01.641
Ngisho naseziminyaka yama-1930, iminyaka
yenhlekelele yezomnotho yomhlaba wonke, umuntu ojwayelekile

02:01.641 --> 02:05.328
mhlawumbe wayengeke acabange ukuzama ukulawula intuthu.

02:05.328 --> 02:14.785
Kodwa abaholi bezempi bezwe noma imboni yezikhali,
abafuna ukuqala enye impi, bazobona lokhu kanjani?

02:14.785 --> 02:20.213
Noma ubani ongakwazi ukudala intuthu eyenziwe
ngabantu futhi ayenze inyamalale futhi unethuluzi

02:20.213 --> 02:26.072
elinamandla, inzuzo engadlala indima ebalulekile empini.

02:26.072 --> 02:32.290
I-UN yathatha lolu hlobo lwesikhali ngokungathi sína
kakhulu futhi yaphendula ngesivumelwano sokuguqulwa kwemvelo.

02:32.290 --> 02:38.743
Lokhu kuvimbela impi ngokuguqulwa kwemvelo
futhi kube semthethweni kusukela ngo-1978.

02:38.743 --> 02:44.445
Impela, lokhu akusho ukuthi lezi zindlela
zokudlala ngezinhlelo azisasetshenziswa.

02:44.445 --> 02:51.610
Kuphambene nalokho: ngokulandela lesi sivumelwano se-UN,
amapatenti okuguqulwa kwesimo sezulu aqhubeka nokunikezwa.

02:51.610 --> 02:58.359
Ohlelweni olubizwa ngokuthi "Isimo sezulu esinzima eSpain: Izwi
eliphikisana nezikhali zezulu ne-Agenda 2030" , i-Kla.TV yachaza

02:58.359 --> 03:04.949
ukuthi nakuba abezepolitiki kanye neziteshi zezindaba ezinkulu
basola ngokushesha ukuguquka kwesimo sezulu okubangelwa abantu

03:04.949 --> 03:09.483
ngalolu bhubhane, abavikeli bemvelo kanye
nengxenye yomphakathi ekhulayo babona ukuthi

03:09.483 --> 03:14.043
ukusetshenziswa kwezikhali zezulu sekufakazelwe.

03:14.043 --> 03:19.403
Kuzo zonke izimo zezinhlekelele zezulu
ezinzima, kufanele-ke kugcinwe engqondweni uxhumano

03:19.403 --> 03:22.011
nezikhali zezulu futhi kuphenywe ngokucophelela.
