The first pairs of jeans were designed for durability.

Prve farmerke su napravljene sa ciljem da bi trajale.
00:10
Named for the French city of Nîmes,
1
10204
2292
Nazvan po francuskom gradu Nim,
00:12
denim was constructed as a sturdy cotton weave worn by sailors.
2
12913
3958
teksas (denim) je izrađen kao jaka pamučna tkanina za mornare.
00:17
This rugged material got even stronger in the 19th century,
3
17288
3541
Ovaj grubi materijal je ojačan u devetnaestom veku
00:20
when Levi Strauss and Jacob Davis added metal rivets to reinforce stress points.
4
20829
5000
kada su Livaj Štraus i Džejkob Dejvis dodali metalne nitne na kritične tačke.
00:26
Their design introduced a new brand of durable trousers
5
26496
2708
Njihov dizajn je uveo novi brend izdržljivih farmerki
00:29
for California miners that could withstand years of wear and tear.
6
29204
3708
za kalifornijske rudare koji je mogao da potraje godinama.
00:33
Over the course of the 20th century,
7
33496
1958
Tokom dvadesetog veka,
00:35
these working-class pants have transformed into fashion icons.
8
35454
3750
ove radničke pantalone postale su modne ikone.
00:39
But as the demand for jeans has gone up, their durability has gone down.
9
39787
4459
Kako je potražnja za farmerkama porasla, njihova izdržljivost je opala.
00:44
Today, most pairs last no longer than a year.
10
44746
2708
Danas, par farmerki ne traje duže od godinu dana.
00:47
And each new pair you buy has a much higher cost than you might think.
11
47746
3916
Svaki novi par koji kupite je skuplji nego što mislite.
00:51
Every pair of jeans begins its life in a cotton field.
12
51996
3041
Svaki par farmerki započinje svoj život na polju pamuka.
00:55
It takes about 0.7 kilograms of cotton to produce a single pair of pants.
13
55412
4875
Potrebno je 0,7 kilograma pamuka da bi se proizveo jedan par farmerki.
01:00
Growing this much cotton requires roughly 10,000 liters of water,
14
60829
4084
Za uzgoj ovoliko pamuka potroši se otprilike 10 000 litara vode,
01:05
not to mention various herbicides and pesticides,
15
65204
3084
a da ne pominjemo razne herbicide i pesticide,
01:08
which can contaminate groundwater.
16
68454
1792
koji zagađuju podzemne vode.
01:10
The cotton is harvested by hand or industrial machines
17
70788
3291
Pamuk se bere ručno ili uz pomoć industrijskih mašina
01:14
and transported to textile factories where it’s spun into yarn.
18
74079
3250
i transportuje se u tekstilne fabrike gde se prede u predivo.
01:17
At this point, it’s typically combined with plastic fibers like spandex
19
77954
4792
U ovoj fazi obično se kombinuje sa plastičnim vlaknima kao što je spandeks
01:22
to increase the yarn’s elasticity.
20
82746
2000
da bi se povećala elastičnost prediva.
01:24
These plastic threads make modern jeans more comfortable and flexible,
21
84996
3833
Ove plastične niti čine moderne farmerke udobnijim i elastičnijim,
01:28
but also much less durable.
22
88829
1959
ali u isto vreme i manje izdržljivim.
01:31
Next, the yarn is dyed jeans’ trademark blue.
23
91204
3167
Nakon toga, predivo se boji u teksas plavu boju.
01:34
Historically, this color came from natural plant-derived indigo.
24
94704
3625
U prošlosti se ova boja dobijala od prirodnog biljnog indiga.
01:38
But most modern manufacturers use a synthetic dye
25
98579
3125
Međutim, većina današnjih proizvođača koristi sintetičke boje
01:41
made from petroleum byproducts and toxic chemicals.
26
101704
3167
dobijene od naftnih derivata i toksičnih hemikalija.
01:45
Once dyed, the cotton-plastic blend is woven into denim sheets,
27
105329
4042
Kada se oboji, mešavina pamuka i plastike se tka u teksasne čaršave,
01:49
which are then cut and sewn into jeans.
28
109371
2333
koji se potom seku i od njih se šiju farmerke.
01:52
After assembly, some jeans undergo additional procedures
29
112246
3625
Nakon šivenja, na nekim farmerkama se vrše dodatne procedure
01:55
to get a distressed look.
30
115871
1458
da bi se dobio istrošen izgled.
01:57
This often includes chemical sprays and multiple cycles of acid-washing,
31
117413
4416
Ovo često uključuje hemijske sprejeve i višestruko pranje kiselinom.
02:02
the toxic runoff can turn rivers indigo-blue.
32
122079
2875
Toksični otpad može da oboji reke u indigo plavu boju.
02:05
Finally, there are the zippers, buttons, and rivets
33
125496
3083
Na kraju, tu su rajsferšlusi, dugmad i nitne
02:08
made of copper and other metals,
34
128579
1792
koji se prave od bakra i drugih metala,
02:10
whose mining is yet another source of environmental degradation.
35
130371
3375
čije iskopavanje je dodatni vid degradacije životne sredine.
02:14
All in all, the manufacturing process for a single pair of jeans
36
134413
3916
Sve u svemu, proizvodni proces jednog para farmerki
02:18
emits over 33 kilograms of carbon—
37
138329
2792
oslobađa preko 33 kilograma ugljenika,
02:21
the equivalent of driving over 110 kilometers.
38
141413
3166
što bi bilo jednako vožnji od 110 kilometara.
02:24
But this process doesn't just damage the environment.
39
144913
2833
Međutim, ovaj proces ne šteti samo životnoj sredini.
02:28
Much of the world’s cotton is grown in developing countries,
40
148163
3000
Većina svetskog pamuka se uzgaja u zemljama u razvoju
02:31
with poor labor practices and few protections for workers.
41
151163
3250
koje imaju loše uslove za rad i slabu zaštitu radnika.
02:35
Cotton here is often picked by children or forced labor,
42
155121
3333
Pamuk često beru deca ili prisilni radnici,
02:38
and most jean manufacturing plants frequently expose workers
43
158454
3792
i većina fabrika za proizvodnju džinsa često izlaže radnike
02:42
to toxic chemicals throughout production.
44
162246
2167
otrovnim hemikalijama u toku proizvodnje.
02:44
One particularly dangerous technique called sandblasting
45
164996
3458
Jedna posebno opasna tehnika zvana peskarenje
02:48
involves spraying jeans with fine sand at high pressures
46
168704
3709
podrazumeva prskanje farmerki sitnim peskom pod velikim pritiskom
02:52
and has been linked with numerous cases of incurable and often fatal lung disease.
47
172413
4750
i dovodi se u vezu sa mnogim slučajevima
neizlečivog raka pluća i drugih kobnih bolesti.
02:57
Like many globally produced products,
48
177413
2166
Kao i mnogi proizvodi koji se prave širom sveta,
02:59
jeans are made in poor countries and bought in rich ones.
49
179579
2917
farmerke se prave u siromašnim državama, a kupuju u bogatim.
03:02
All these pants will likely be washed dozens or even hundreds of times per year.
50
182996
4583
Sve ove farmerke se peru desetinama ili stotinama puta godišnje.
03:07
This energy intensive process breaks down the plastics woven into each pair,
51
187829
4209
Ovaj energetski iscrpljujući proces kida plastične niti utkane u svaki par
03:12
releasing microplastics into the water
52
192038
2416
oslobađajući mikroplastiku u vodu
03:14
and, perhaps most ironic of all, shortening the jean’s lifespan.
53
194454
3792
i, ono što je ironično u svemu, skraćujući trajanje farmerki.
03:18
Like most waste, discarded jeans end up in landfills,
54
198579
3500
Kao i većina otpada, bačene farmerke završe na deponijama
03:22
where their decomposition releases methane gas,
55
202079
2750
gde se prilikom raspadanja oslobađa metan,
03:24
while their dyes and plastics leach into the soil and groundwater.
56
204829
3459
dok boje i plastika cure u zemljište i u podzemne vode.
03:28
Some companies are working on solutions here,
57
208913
2500
Neke kompanije rade na traženju rešenja,
03:31
from using organic cotton to recycling and reusing denim.
58
211413
3375
kao što su korišćenje organskog pamuka, recikliranje i ponovna upotreba teksasa.
03:35
You can also help reduce the environmental impact of your favorite pants
59
215204
3584
I vi možete pomoći da se smanji uticaj na životnu sredinu
03:38
by buying used jeans and buying fewer pairs altogether.
60
218788
3833
tako što ćete kupovati polovnu robu i u manjim količinama.
03:42
Denim manufacturers also recommend only washing your jeans once every 10 wears.
61
222913
4916
Proizvođači teksasa preporučuju da perete farmerke nakon deset nošenja.
03:47
And, when possible, air dry your pants to reduce energy consumption.
62
227829
3709
Kada je moguće, sušite svoje farmerke na vetru i smanjite potrošnju energije.
03:51
Life cycle and labor problems like these extend far beyond just jeans.
63
231829
4250
Životni ciklus i ovakvi radnički problemi ne obuhvataju samo farmerke.
03:56
Some governments are pursuing policies to make companies more responsible
64
236579
3709
Neke države sprovode planove po kojima bi kompanije bile odgovornije
04:00
for worker pay and welfare,
65
240288
1666
za plaćanje radnika i socijalnu pomoć,
04:02
but unsustainable practices still run rampant throughout the fashion industry.
66
242204
4125
ali neodrživa praksa je i dalje van kontrole u celoj modnoj industriji.
04:06
So when the price tags on your clothes seem like a steal,
67
246329
2917
I zato kada vidite da cena na vašoj odeći izgleda kao pljačka,
04:09
it’s important to consider who’s actually being robbed.
68
249246
3125
važno je da razmislite ko je zapravo opljačkan.
