Since the dawn of humanity,
0
6794
1661
Od samog početka čovečanstva,
00:08
an estimated 100.8 billion people have lived and died,
1
8455
5421
procenjuje se da je živelo i umrlo 100,8 milijardi ljudi,
00:13
a number that increases by about .8% of the world's population each year.
2
13876
5360
što je broj koji se svake godine povećava za 0,8% svetske populacije.
00:19
What happens to all of those people's bodies after they die
3
19236
3220
Šta se dešava sa telima svih tih ljudi nakon što umru
00:22
and will the planet eventually run out of burial space?
4
22456
4259
i da li će na kraju na planeti nestati mesta za sahranjivanje?
00:26
When a person's heart stops beating,
5
26715
1791
Kada srce osobe prestane da kuca,
00:28
the body passes through several stages before it begins decomposing.
6
28506
4150
telo prolazi kroz nekoliko faza pre nego što počne da se raspada.
00:32
Within minutes after death,
7
32656
1631
Nekoliko minuta nakon smrti,
00:34
the blood begins settling in the lower-most parts of the body.
8
34287
3679
krv počinje da se taloži u najnižim delovima tela.
00:37
Usually eight to twelve hours later,
9
37966
2039
Obično osam do dvanaest sati kasnije,
00:40
the skin in those areas is discolored by livor mortis, or post-mortem stain.
10
40005
6079
koža menja boju u tim oblastima zbog mrtvačkih ili postmortalnih mrlja.
Dok se u trenutku smrti mišići u telu potpuno opuštaju
00:46
And while at the moment of death the body's muscles relax completely
11
46084
3812
00:49
in a condition called primary flaccidity,
12
49896
2781
u stanju zvanom primarna mlitavost,
00:52
they stiffen about two to six hours later in what's known as rigor mortis.
13
52677
5570
ukrućuju se oko dva do šest sati kasnije
u onome što je poznato kao mrtvačka ukočenost.
00:58
This stiffening spreads through the muscles,
14
58247
2130
Ukočenost se širi kroz mišiće
01:00
and its speed can be affected by age, gender, and the surrounding environment.
15
60377
5210
i na njegovu brzinu može uticati starost, pol, kao i okruženje.
01:05
The body also changes temperature,
16
65587
2001
Takođe se menja temperatura tela
01:07
usually cooling off to match its environment.
17
67588
3309
tako što se obično hladi da bi se prilagodilo sredini.
01:10
Next comes decomposition,
18
70897
2158
Zatim nastupa raspadanje,
proces u kome bakterije i insekti razlažu telo.
01:13
the process by which bacteria and insects break apart the body.
19
73055
4183
01:17
Many factors affect the rate of decomposition.
20
77238
3039
Mnogi faktori utiču na brzinu raspadanja.
01:20
There is, however, a basic guide of the effect of the environment on decompositon
21
80277
4520
Međutim, postoji osnovni vodič o uticaju sredine na raspadanje
01:24
called Casper's Law.
22
84797
1961
zvani Kasperov zakon.
01:26
It says that if all other factors are equal,
23
86758
2209
On kaže da, ako su ostali faktori isti,
01:28
a body exposed to air decomposes twice as fast as one immersed in water
24
88967
6231
telo izloženo vazduhu se raspada dvaput brže od onog uronjenog u vodu
01:35
and eight times as fast as one buried in earth.
25
95198
4124
i osam puta brže od onog koje je zakopano u zemlji.
01:39
Soil acidity also greatly affects bone preservation.
26
99322
4232
Kiselost zemljišta takođe u velikoj meri utiče na očuvanost kostiju.
01:43
High-acidity soils with a pH of less than 5.3
27
103554
3427
Vrlo kisela zemljišta sa pH vrednošću ispod 5,3
01:46
will rapidly decompose bone,
28
106981
2677
brzo će razložiti kost,
01:49
whereas in a neutral or basic soil with a pH of 7 or more,
29
109658
5081
dok u zemljištu sa neutralnom ili bazičnom kiselošću sa pH od 7 i više
01:54
a skeleton can remain in relatively good condition for centuries.
30
114739
4946
skelet može vekovima ostati u relativno dobrom stanju.
01:59
Different cultures throughout history have developed unique approaches to burials.
31
119685
4403
Različite kulture su kroz istoriju razvile jedinstvene pristupe sahranama.
Još od prvih sahrana neandertalaca,
02:04
As far back as the first Neanderthal burials,
32
124088
2632
02:06
death was accompanied by rituals,
33
126720
2380
smrt je bila propraćena ritualima
kao što su nameštanje, bojenje i ukrašavanje leševa.
02:09
like the positioning, coloring, or decorating of corpses.
34
129100
4318
02:13
Traditional Christian burials decorate the body in dress,
35
133418
3584
Tradicionalne hrišćanske sahrane ukrašavaju telo odećom,
dok se u tradicionalnom islamu
02:17
while in traditional Islam,
36
137002
1458
02:18
a body is wrapped in a piece of ritual fabric
37
138460
2480
telo umotava u ritualnu tkaninu,
02:20
with the face oriented toward Mecca.
38
140940
3119
pri čemu je lice okrenuto ka Meki.
Tradicionalni hinduisti ceremonijalno spaljuju telo,
02:24
Traditional Hindus ceremonially burn the body,
39
144059
2964
a zaratustranci, sledbenici jedne od najstarijih monoteističkih religija,
02:27
and Zoroastrians, followers of one of the oldest monotheistic religions,
40
147023
4247
02:31
traditionally place bodies atop a tower to expose them to the Sun
41
151270
4373
prema tradiciji postavljaju tela na vrh kule i izlažu ih Suncu
02:35
and scavenging birds.`
42
155643
2361
i pticama lešinarima.
02:38
Before the Industrial Revolution, burials were simple and accessible.
43
158004
4243
Pre industrijske revolucije, sahranjivanje je bilo jednostavno i pristupačno.
02:42
These days, with suitable burial land running out in high-population areas,
44
162247
4944
U današnje vreme,
kada ponestaje pogodnih zemljišta u oblastima koje su gusto naseljene,
02:47
purchasing private gravesites can be costly,
45
167191
3099
kupovanje privatnih grobnih mesta može biti skupo
02:50
and many people can't afford simple burials.
46
170290
2757
i mnogi ljudi ne mogu da priušte jednostavne sahrane.
Čak i kremiranje, drugi po učestalosti pogrebni običaj u svetu,
02:53
Even cremation, the second most common burial practice in the world,
47
173047
3815
02:56
comes with a high cost.
48
176862
2347
ima visoku cenu.
Što se tiče pitanja ponestajanja mesta,
02:59
As for the question of running out of space,
49
179209
2183
03:01
the issue isn't so much about total land in the world
50
181392
2910
problem nije toliko u ukupnoj zemlji na svetu
03:04
as it is that large populations cluster together within cities.
51
184302
4486
koliko u tome što se velike grupe stanovništva grupišu u gradovima.
03:08
Most of the big cities in the world
52
188788
2189
Većini velikih gradova na svetu
03:10
may run out of suitable burial grounds within a century.
53
190977
3593
moglo bi ponestati pogodnih grobnih mesta u roku od jednog veka.
03:14
For London, it's even sooner.
54
194570
1820
U slučaju Londona, još ranije.
03:16
That may happen by 2035.
55
196390
2493
To se može dogoditi do 2035. godine.
03:18
So are there alternatives to traditional burials
56
198883
2959
Postoje li alternative za tradicionalno sahranjivanje
03:21
that might help with the space issue?
57
201842
2550
koje bi mogle da pomognu u vezi sa ovim problemom prostora?
03:24
In some countries, skyscraper cemeteries enable vertical burials.
58
204392
4949
U nekim zemljama groblja u vidu nebodera omogućavaju vertikalno sahranjivanje.
03:29
Some options focus on the body's relationship with the environment.
59
209341
3512
Neke opcije su usmerene na odnos tela sa životnom sredinom.
03:32
Promession, for example, freeze-dries and pulverizes the body,
60
212853
4940
Promesija, na primer, suši telo smrzavanjem i pulverizuje telo,
03:37
creating a powder that can turn into compost
61
217793
2549
stvarajući prah koji može da se pretvori u đubrivo
03:40
when mixed with oxygen and water.
62
220342
2969
kada se pomeša sa kiseonikom i vodom.
03:43
There are also green burials that use special materials,
63
223311
3147
Takođe postoji zeleno sahranjivanje koje koristi specijalne materijale
03:46
such as biodegradable caskets,
64
226458
2193
kao što su biorazgradivi sanduci,
03:48
urns that sprout trees,
65
228651
1891
urne iz kojih niče drveće
03:50
and burial suits that grow mushrooms.
66
230542
3260
i pogrebna odela iz kojih rastu pečurke.
03:53
Eternal reefs take that concept to the depths of the ocean
67
233802
3640
Večni grebeni donose taj koncept u okeanske dubine
03:57
using a mixture of ashes and cement to create marine habitats for sea life.
68
237442
5991
koristeći mešavinu pepela i cementa
da bi stvorili morska staništa za morska stvorenja.
04:03
Death is an inevitable part of the human condition,
69
243433
3119
Smrt je neizbežni deo ljudske situacije,
04:06
but how we treat bodies and burials continues to evolve.
70
246552
3931
ali način na koji se ophodimo prema telima i sahranjivanju nastavlja da se razvija.
04:10
We may each have different spiritual,
71
250483
1909
Svi mi možemo imati različite duhovne,
04:12
religious,
72
252392
981
verske ili praktične pristupe umiranju,
04:13
or practical approaches to dying,
73
253373
2570
04:15
but the ever-increasing demand for burial space
74
255943
2590
ali bi nas sve veća potražnja za grobnim mestima
04:18
might give us a push to be creative
75
258533
2159
mogla pokrenuti da budemo kreativni
04:20
about where our bodies go after the final stages of life.
76
260692
3971
u pogledu toga gde naša tela odlaze nakon poslednjih faza života.
