This is our life with bees,
0
12883
3980
Ovo je naš život sa pčelama,
00:16
and this is our life without bees.
1
16863
3723
a ovo bez pčela.
00:20
Bees are the most important pollinators
2
20586
2468
Pčele su najvažniji oprašivači
00:23
of our fruits and vegetables and flowers
3
23054
2809
našeg voća, povrća i cveća,
00:25
and crops like alfalfa hay that feed our farm animals.
4
25863
3659
i biljaka poput deteline koje hrane naše domaće životinje.
00:29
More than one third of the world's crop production
5
29522
2688
Više od jedne trećine svetske proizvodnje useva
00:32
is dependent on bee pollination.
6
32210
2782
zavisi od pčelinjeg oprašivanja.
00:34
But the ironic thing is that bees are not out there
7
34992
2837
Ali ironično je to što pčele
00:37
pollinating our food intentionally.
8
37829
2917
ne oprašuju našu hranu namerno.
00:40
They're out there because they need to eat.
9
40746
2871
One to rade jer moraju da jedu.
00:43
Bees get all of the protein they need in their diet
10
43617
2719
Pčele dobijaju sve proteine koji su im potrebni u ishrani
00:46
from pollen
11
46336
1329
iz polena
00:47
and all of the carbohydrates they need from nectar.
12
47665
2936
i sve ugljene hidrate koji su im potrebni iz nektara.
00:50
They're flower-feeders,
13
50601
1765
One se hrane cvećem,
00:52
and as they move from flower to flower,
14
52366
1934
i dok se kreću od cveta do cveta,
00:54
basically on a shopping trip at the local floral mart,
15
54300
3471
kao da kupuju u lokalnoj cvećari,
00:57
they end up providing this valuable pollination service.
16
57771
4455
one pružaju vrednu uslugu oprašivanja.
01:02
In parts of the world where there are no bees,
17
62226
2520
U delovima sveta gde nema pčela,
01:04
or where they plant varieties that are not attractive to bees,
18
64746
2906
ili gde rastu biljke koje nisu privlačne pčelama,
01:07
people are paid to do the business of pollination by hand.
19
67652
4206
ljudi su plaćeni da ručno vrše oprašivanje.
01:11
These people are moving pollen from flower to flower
20
71858
3684
Ovi ljudi prenose polen sa jednog cveta na drugi
01:15
with a paintbrush.
21
75542
1899
pomoću četke.
01:17
Now this business of hand pollination
22
77441
2446
Danas ovaj posao ručnog oprašivanja
01:19
is actually not that uncommon.
23
79887
2086
zapravo nije tako neobičan.
01:21
Tomato growers often pollinate their tomato flowers
24
81973
3352
Uzgajivači paradajza često oprašuju cvetove svojih biljaka
01:25
with a hand-held vibrator.
25
85325
2657
pomoću ručnog vibratora.
01:27
Now this one's the tomato tickler. (Laughter)
26
87982
3944
Dakle, ovako se golica paradajz. (Smeh)
01:31
Now this is because the pollen within a tomato flower
27
91926
5280
S obzirom da se polen u cvetu paradajza
01:37
is held very securely within
28
97206
1780
čuva na sigurnom, unutar cveta,
01:38
the male part of the flower, the anther,
29
98986
2500
u muškom delu cveta, prašniku,
01:41
and the only way to release this pollen is to vibrate it.
30
101486
3374
jedini način da se taj polen oslobodi je vibracija prašnika.
01:44
So bumblebees are one of the few kinds of bees in the world
31
104860
3686
Bumbari su jedna od nekoliko vrsta pčela na svetu
01:48
that are able to hold onto the flower and vibrate it,
32
108546
3123
koje su sposobne da se drže za cvet i da ga vibriraju,
01:51
and they do this by shaking their flight muscles
33
111669
2592
a to rade trešenjem svojih mišića za letenje
01:54
at a frequency similar to the musical note C.
34
114261
4552
na frekvenciji koja je slična muzičkoj noti C.
01:58
So they vibrate the flower, they sonicate it,
35
118813
2586
Dok vibriraju cvet, oni ga rastvore
02:01
and that releases the pollen in this efficient swoosh,
36
121399
3047
i to oslobađa polen,
02:04
and the pollen gathers all over the fuzzy bee's body,
37
124446
2739
i polen se skuplja po čupavom telu bumbara
02:07
and she takes it home as food.
38
127185
2497
i on ga odnosi kući kao hranu.
02:09
Tomato growers now put bumblebee colonies
39
129682
2841
Uzgajivači paradajza sada postavljaju kolonije bumbara
02:12
inside the greenhouse to pollinate the tomatoes
40
132523
2531
unutar plastenika da bi oprašili njihov paradajz,
02:15
because they get much more efficient pollination
41
135054
2363
jer dobiju mnogo efikasnije oprašivanje
02:17
when it's done naturally
42
137417
1495
kada se vrši prirodnim putem
02:18
and they get better quality tomatoes.
43
138912
3562
i dobiju kvalitetnije plodove.
02:22
So there's other, maybe more personal reasons,
44
142474
3587
Postoje i drugi, možda više lični razlozi,
02:26
to care about bees.
45
146061
1423
za brigu o pčelama.
02:27
There's over 20,000 species of bees in the world,
46
147484
4172
Postoji preko 20 000 vrsta pčela na svetu
02:31
and they're absolutely gorgeous.
47
151656
3006
i sve su apsolutno predivne.
02:34
These bees spend the majority of their life cycle
48
154662
2619
Pčele provedu većinu svog životnog ciklusa
02:37
hidden in the ground or within a hollow stem
49
157281
2820
skrivene u zemlji ili unutar šupljih stabala,
02:40
and very few of these beautiful species
50
160101
2700
i mali broj ovih prelepih vrsta
02:42
have evolved highly social behavior like honeybees.
51
162801
3433
je razvio visoko društveno ponašanje kao medonosne pčele.
02:46
Now honeybees tend to be the charismatic representative
52
166234
3620
Ove pčele su harizmatični predstavnici
02:49
for the other 19,900-plus species
53
169854
3169
ostalih, preko 19 900 vrsta,
02:53
because there's something about honeybees
54
173023
2641
jer postoji nešto kod medonosnih pčela
02:55
that draws people into their world.
55
175664
2849
što privlači ljude u njihov svet.
02:58
Humans have been drawn to honeybees
56
178513
2447
Ljude su pčele privlačile
03:00
since early recorded history,
57
180960
1716
još od početka zabeležene istorije,
03:02
mostly to harvest their honey,
58
182676
1476
uglavnom da bi ubirali njihov med,
03:04
which is an amazing natural sweetener.
59
184152
3459
koji je izvrstan prirodni zaslađivač.
03:07
I got drawn into the honeybee world
60
187611
1788
Mene je svet pčela privukao
03:09
completely by a fluke.
61
189399
2085
potpuno slučajno.
03:11
I was 18 years old and bored,
62
191484
2322
Imala sam 18 godina i dosađivala se,
03:13
and I picked up a book in the library on bees
63
193806
2862
i u biblioteci sam pokupila knjigu o pčelama
03:16
and I spent the night reading it.
64
196668
2242
i provela sam noć čitajući je.
03:18
I had never thought about insects
65
198910
1927
Nikad nisam razmišljala o insektima
03:20
living in complex societies.
66
200837
1723
koji žive u složenim društvima.
03:22
It was like the best of science fiction come true.
67
202560
3402
Bilo je to kao da se obistinila najbolja naučna fantastika.
03:25
And even stranger, there were these people,
68
205962
2894
I da bude još čudnije, postojali su ljudi,
03:28
these beekeepers, that loved their bees like they were family,
69
208856
3991
pčelari, koji su voleli pčele kao da su porodica, i kada sam
03:32
and when I put down the book, I knew I had to see this for myself.
70
212847
3303
odložila knjigu, znala sam da sama moram to da vidim.
03:36
So I went to work for a commercial beekeeper,
71
216150
2485
Tako sam počela da radim za jednog komercijalnog pčelara,
03:38
a family that owned 2,000 hives of bees in New Mexico.
72
218635
4197
porodicu koja je posedovala 2000 pčelinjih košnica u Nju Meksiku.
03:42
And I was permanently hooked.
73
222832
3407
I trajno sam se "navukla".
03:46
Honeybees can be considered a super-organism,
74
226239
3314
Medonosne pčele se mogu smatrati super-organizmom,
03:49
where the colony is the organism
75
229553
2156
gde je kolonija organizam
03:51
and it's comprised of 40,000 to 50,000
76
231709
2732
koji se sastoji od 40 000 do 50 000
03:54
individual bee organisms.
77
234441
2928
pojedinačnih pčelinjih organizama.
03:57
Now this society has no central authority.
78
237369
3332
Njihovo društvo nema centralni autoritet.
04:00
Nobody's in charge.
79
240701
1596
Niko nije glavni.
04:02
So how they come to collective decisions,
80
242297
2345
Kako one dolaze do zajedničkih odluka,
04:04
and how they allocate their tasks and divide their labor,
81
244642
2980
i kako dodeljuju zadatke i dele posao,
04:07
how they communicate where the flowers are,
82
247622
2482
kako komuniciraju o poziciji cvetova,
04:10
all of their collective social behaviors are mindblowing.
83
250104
4164
svo njihovo kolektivno društveno ponašanje je zapanjujuće.
04:14
My personal favorite, and one that I've studied for many years,
84
254268
3768
Meni omiljeni, i predmet mog dugogodišnjeg proučavanja,
04:18
is their system of healthcare.
85
258036
1945
je njihov sistem zdravstvene zaštite.
04:19
So bees have social healthcare.
86
259981
3485
Dakle, pčele imaju društvenu zdravstvenu zaštitu.
04:23
So in my lab, we study how bees keep themselves healthy.
87
263466
4270
U mojoj laboratoriji proučavamo kako pčele održavaju svoje zdravlje.
04:27
For example, we study hygiene,
88
267736
2339
Na primer, proučavamo higijenu,
04:30
where some bees are able to locate and weed out
89
270075
2886
gde su neke pčele sposobne da lociraju i izdvoje
04:32
sick individuals from the nest, from the colony,
90
272961
3167
bolesne jedinke iz kolonije
04:36
and it keeps the colony healthy.
91
276128
2464
i tako održavaju koloniju zdravom.
04:38
And more recently, we've been studying resins
92
278592
3427
Nedavno, proučavali smo smolu
04:42
that bees collect from plants.
93
282019
2109
koju pčele skupljaju sa biljaka.
04:44
So bees fly to some plants and they scrape
94
284128
3183
Pčele lete do određenih biljaka i stružu
04:47
these very, very sticky resins off the leaves,
95
287311
2656
veoma lepljivu smolu sa listova,
04:49
and they take them back to the nest
96
289967
1578
i odnose je natrag u košnicu,
04:51
where they cement them into the nest architecture
97
291545
2866
gde je ugrađuju u konstrukciju košnice,
04:54
where we call it propolis.
98
294411
2525
a mi je nazivamo propolisom.
04:56
We've found that propolis is a natural disinfectant.
99
296936
4622
Otkrili smo da je propolis prirodno sredstvo za dezinfekciju.
05:01
It's a natural antibiotic.
100
301558
1944
Prirodni je antibiotik.
05:03
It kills off bacteria and molds and other germs
101
303502
3179
Ubija bakterije i gljivice i druge klice
05:06
within the colony,
102
306681
1602
u koloniji,
05:08
and so it bolsters the colony health and their social immunity.
103
308283
3963
i tako podstiče zdravlje kolonije i zajednički imunitet pčela.
05:12
Humans have known about the power of propolis
104
312246
3291
Ljudi poznaju moć propolisa
05:15
since biblical times.
105
315537
1647
od biblijskih vremena.
05:17
We've been harvesting propolis out of bee colonies
106
317184
3350
Skupljali smo propolis iz pčelinjih kolonija
05:20
for human medicine,
107
320534
2052
za lečenje ljudi
05:22
but we didn't know how good it was for the bees.
108
322586
3664
ali nismo znali koliko je koristan za pčele.
05:26
So honeybees have these remarkable natural defenses
109
326250
4053
Pčele imaju izvanrednu prirodnu odbranu
05:30
that have kept them healthy and thriving
110
330303
2689
koja im čuva zdravlje i napredak
05:32
for over 50 million years.
111
332992
4257
preko 50 miliona godina.
05:37
So seven years ago, when honeybee colonies
112
337249
3349
Pre sedam godina, kada je zabeleženo
05:40
were reported to be dying en masse,
113
340598
1799
masovno izumiranje pčelinjih kolonija,
05:42
first in the United States,
114
342397
1972
prvo u Sjedinjenim Državama,
05:44
it was clear that there was something really, really wrong.
115
344369
3813
bilo je jasno da se dešava nešto veoma, veoma loše.
05:48
In our collective conscience, in a really primal way,
116
348182
3486
U našoj kolektivnoj savesti, na zaista primaran način,
05:51
we know we can't afford to lose bees.
117
351668
3186
ne smemo sebi priuštiti gubitak pčela.
05:54
So what's going on?
118
354854
3115
Šta se dešava?
05:57
Bees are dying from multiple and interacting causes,
119
357969
4089
Pčele umiru zbog mnogobrojnih međusobno povezanih uzroka,
06:02
and I'll go through each of these.
120
362058
2482
i proći ću kroz svaki od njih.
06:04
The bottom line is,
121
364540
1853
Suština je,
06:06
bees dying reflects a flowerless landscape
122
366393
4052
da izumiranje pčela odražava pejzaž bez cveća
06:10
and a dysfunctional food system.
123
370445
3489
i disfunkcionalan sistem ishrane.
06:13
Now we have the best data on honeybees,
124
373934
1992
Posedujemo najbolje podatke o pčelama,
06:15
so I'll use them as an example.
125
375926
1856
pa ću ih koristiti kao primer.
06:17
In the United States, bees in fact have been
126
377782
3493
U Sjedinjenim Državama, broj pčela
06:21
in decline since World War II.
127
381275
2864
opada od Drugog svetskog rata.
06:24
We have half the number of managed hives
128
384139
2274
Imamo upola manje košnica
06:26
in the United States now compared to 1945.
129
386413
3014
u Sjedinjenim Državama danas u odnosu na 1945. godinu.
06:29
We're down to about two million hives of bees, we think.
130
389427
3651
Pretpostavljamo da smo u minusu za oko 2 miliona pčelinjih košnica.
06:33
And the reason is, after World War II,
131
393078
2746
A razlog je taj što smo nakon Drugog svetskog rata,
06:35
we changed our farming practices.
132
395824
3328
promenili svoju poljoprivrednu praksu.
06:39
We stopped planting cover crops.
133
399152
2839
Prestali smo da sadimo biljke koje proizvode humus.
06:41
We stopped planting clover and alfalfa,
134
401991
2743
Prestali smo da sadimo detelinu,
06:44
which are natural fertilizers that fix nitrogen in the soil,
135
404734
3846
koja je prirodno đubrivo koje reguliše nivo azota u tlu,
06:48
and instead we started using synthetic fertilizers.
136
408580
3604
a umesto toga, počeli smo da koristimo veštačka đubriva.
06:52
Clover and alfalfa are highly nutritious food plants for bees.
137
412184
5544
Detelina i lucerka su za pčele veoma hranjive biljke.
06:57
And after World War II, we started using herbicides
138
417728
3454
Nakon Drugog svetskog rata, počeli smo da koristimo i herbicide
07:01
to kill off the weeds in our farms.
139
421182
2497
da iskorenimo korov na našim farmama.
07:03
Many of these weeds are flowering plants
140
423679
2781
Mnogi od tih korova su biljke koje cvetaju,
07:06
that bees require for their survival.
141
426460
2933
pčelama neophodne za preživljavanje.
07:09
And we started growing larger and larger crop monocultures.
142
429393
5571
I počeli smo da uzgajamo sve veće i veće monokulture useva.
07:14
Now we talk about food deserts,
143
434964
2565
Danas govorimo o pustinjama hrane,
07:17
places in our cities, neighborhoods that have no grocery stores.
144
437529
4250
mestima u našim gradovima, kvartovima koji nemaju prodavnice voća i povrća.
07:21
The very farms that used to sustain bees
145

Farme koje su nekad održavale pčele
07:25
are now agricultural food deserts,
146
445822
2756
sada su poljoprivredne pustinje hrane,
07:28
dominated by one or two plant species
147
448578
2423
kojima dominiraju jedna ili dve biljne vrste
07:31
like corn and soybeans.
148
451001
2589
poput kukuruza ili soje.
07:33
Since World War II, we have been systematically
149
453590
2905
Od Drugog svetskog rata, sistematski smo
07:36
eliminating many of the flowering plants
150
456495
2899
eliminisali mnoge cvetajuće biljke
07:39
that bees need for their survival.
151
459394
3552
koje su pčelama neophodne za preživljavanje.
07:42
And these monocultures extend even to crops
152
462946
2898
Ove monokulture se šire čak i do useva
07:45
that are good for bees, like almonds.
153
465844
2547
koji su dobri za pčele, kao što su bademi.
07:48
Fifty years ago, beekeepers would take a few colonies,
154
468391
3986
Pre pedeset godina, pčelari bi postavili nekoliko kolonija
07:52
hives of bees into the almond orchards, for pollination,
155
472377
3011
pčelinjih košnica u voćnjake badema, radi oprašivanja,
07:55
and also because the pollen in an almond blossom
156
475388
3932
a takođe i zato što je polen bademovog cveta
07:59
is really high in protein. It's really good for bees.
157
479320
4180
zaista bogat proteinima. Stvarno je dobar za pčele.
08:03
Now, the scale of almond monoculture
158
483500
3997
Danas, veličina monokulture badema
08:07
demands that most of our nation's bees,
159
487497
2552
zahteva da većina naših pčela,
08:10
over 1.5 million hives of bees,
160
490049
2736
preko 1,5 miliona pčela,
08:12
be transported across the nation
161
492785
2992
bude prevezena preko čitave zemlje
08:15
to pollinate this one crop.
162
495777
2351
da bi oprašila ovu jednu vrstu useva.
08:18
And they're trucked in in semi-loads,
163
498128
2645
Prevoze se kamionima,
08:20
and they must be trucked out,
164
500773
2330
zatim se istovaraju,
08:23
because after bloom, the almond orchards
165
503103
2739
jer nakon cvetanja voćnjaci badema
08:25
are a vast and flowerless landscape.
166
505842
5210
postaju ogromna područja bez cveća.
08:31
Bees have been dying over the last 50 years,
167
511052
2466
Pčele izumiru tokom poslednjih 50 godina,
08:33
and we're planting more crops that need them.
168
513518
3805
a mi sadimo više useva nego što nam je potrebno.
08:37
There has been a 300 percent increase in crop production
169
517323
4184
Proizvodnja useva koja zahteva oprašivanje uz pomoć pčela
08:41
that requires bee pollination.
170
521507
3804
povećala se za 300 posto.
08:45
And then there's pesticides.
171
525311
3026
A tu su i pesticidi.
08:48
After World War II, we started using pesticides
172
528337
3344
Nakon Drugog svetskog rata počeli smo da koristimo pesticide
08:51
on a large scale, and this became necessary
173
531681
2564
u velikoj meri i to je postalo neophodno
08:54
because of the monocultures that put out a feast
174
534245
3794
zbog monokultura koje predstavljaju gozbu
08:58
for crop pests.
175
538039
2293
za štetočine.
09:00
Recently, researchers from Penn State University
176
540332
2941
Nedavno, istraživači sa univerziteta Pen Stejt
09:03
have started looking at the pesticide residue
177
543273
3297
počeli su da traže ostatke pesticida
09:06
in the loads of pollen that bees carry home as food,
178
546570
3550
u tovarima polena koje pčele nose kući kao hranu,
09:10
and they've found that every batch of pollen
179
550120
3591
i otkrili su da svaka serija polena
09:13
that a honeybee collects
180
553711
2007
koju medonosna pčela sakupi
09:15
has at least six detectable pesticides in it,
181
555718
3787
sadrži barem šest pesticida koje je moguće otkriti,
09:19
and this includes every class of insecticides,
182
559505
4043
uključujući sve vrste insekticida,
09:23
herbicides, fungicides,
183
563548
2843
herbicida, fungicida,
09:26
and even inert and unlabeled ingredients
184
566391
3580
i čak inertne i neoznačene sastojke
09:29
that are part of the pesticide formulation
185
569971
2572
koji su deo formulacije pesticida,
09:32
that can be more toxic than the active ingredient.
186
572543
4222
te mogu biti više toksični nego aktivni sastojci.
09:36
This small bee is holding up a large mirror.
187
576765
5642
Ova mala pčela drži veliko ogledalo.
09:42
How much is it going to take to contaminate humans?
188
582407
4448
Koliko će vremena proći dok ne zagadi ljude?
09:46
One of these class of insecticides,
189
586855
2980
Jedna vrsta ovih insekticida,
09:49
the neonicontinoids,
190
589835
1375
neonikotinidi,
09:51
is making headlines around the world right now.
191
591210
2260
nalazi se upravo sada u naslovima širom sveta.
09:53
You've probably heard about it.
192
593470
1446
Verovatno ste čuli za njih.
09:54
This is a new class of insecticides.
193
594916
2058
To je nova vrsta insekticida.
09:56
It moves through the plant so that a crop pest,
194
596974
3159
Kreće se kroz biljku, tako da štetočina,
10:00
a leaf-eating insect,
195
600133
1443
insekt koji jede listove,
10:01
would take a bite of the plant
196
601576
1234
kada zagrize biljku,
10:02
and get a lethal dose and die.
197
602810
3340
dobije smrtnu dozu i ugine.
10:06
If one of these neonics, we call them,
198
606150
2823
Ako je jedan od ovih neonika, kako ih zovemo,
10:08
is applied in a high concentration,
199
608973
2454
prisutan u velikoj koncentraciji,
10:11
such as in this ground application,
200
611427
2262
kao u ovoj primeni na tlu,
10:13
enough of the compound moves through the plant
201
613689
2468
dovoljno jedinjenja se kreće kroz biljku
10:16
and gets into the pollen and the nectar,
202
616157
2212
i dospeva u polen i nektar,
10:18
where a bee can consume, in this case,
203
618369
2104
gde pčela može konzumirati, u ovom slučaju,
10:20
a high dose of this neurotoxin
204
620473
3018
visoku dozu neurotoksina,
10:23
that makes the bee twitch and die.
205
623491
4149
od kojeg se pčela grči i ugine.
10:27
In most agricultural settings, on most of our farms,
206
627640
3173
Na većini poljoprivrednih dobara, na većini naših farmi,
10:30
it's only the seed that's coated with the insecticide,
207
630813
3943
samo je seme obloženo insekticidom,
10:34
and so a smaller concentration moves through the plant
208
634756
2991
tako da se manja koncentracija kreće kroz biljku
10:37
and gets into the pollen and nectar,
209
637747
1968
i dolazi u polen i nektar,
10:39
and if a bee consumes this lower dose,
210
639715
2543
i ako pčela konzumira ovu manju dozu,
10:42
either nothing happens
211
642258
1342
ili se ništa ne desi
10:43
or the bee becomes intoxicated and disoriented
212
643600
3588
ili se pčela otruje i postaje dezorijentisana
10:47
and she may not find her way home.
213
647188
3712
i možda nikad ne nađe put kući.
10:50
And on top of everything else, bees have
214
650900
2132
I povrh svega ostalog, pčele imaju
10:53
their own set of diseases and parasites.
215
653032
2268
svoj skup bolesti i parazita.
10:55
Public enemy number one for bees is this thing.
216
655300
2860
Ovo je javni neprijatelj broj jedan za pčele.
10:58
It's called varroa destructor.
217
658160
2305
Zove se varoa razarač.
11:00
It's aptly named.
218
660465
1104
Ime mu odgovara.
11:01
It's this big, blood-sucking parasite
219
661569
2612
To je veliki parazit koji siše krv
11:04
that compromises the bee's immune system
220
664181
2374
i kompromituje imuni sistem pčela
11:06
and circulates viruses.
221
666555
2771
i širi viruse.
11:09
Let me put this all together for you.
222
669326
2929
Dozvolite da vam pojasnim.
11:12
I don't know what it feels like to a bee
223
672255
2667
Ne znam kakav je osećaj biti pčela
11:14
to have a big, bloodsucking parasite running around on it,
224
674922
2701
i imati velikog parazita koji siše krv,
11:17
and I don't know what it feels like to a bee to have a virus,
225
677623
3139
i ne znam kako je biti pčela i imati virus,
11:20
but I do know what it feels like when I have a virus, the flu,
226
680762
5128
ali znam kakav je osećaj imati virus gripa,
11:25
and I know how difficult it is for me to get
227
685890
3232
i znam kako je teško doći do
11:29
to the grocery store to get good nutrition.
228
689122
2789
prodavnice i nabaviti dobru hranu.
11:31
But what if I lived in a food desert?
229
691911
3046
Ali šta da živim u pustinji hrane?
11:34
And what if I had to travel a long distance
230
694957
2495
I šta da moram da putujem daleko
11:37
to get to the grocery store,
231
697452
1873
da dođem do prodavnice,
11:39
and I finally got my weak body out there
232
699325
2874
i kad napokon dovučem svoje slabo telo do tamo,
11:42
and I consumed, in my food,
233
702199
2144
da konzumiram, u svojoj hrani,
11:44
enough of a pesticide, a neurotoxin,
234
704343
2801
dovoljno pesticida, neurotoksina,
11:47
that I couldn't find my way home?
235
707144
2756
da ne mogu pronaći put kući?
11:49
And this is what we mean by multiple
236
709900
3187
Na to mislimo kad govorimo o mnogobrojnim
11:53
and interacting causes of death.
237
713087
3703
meuđupovezanim uzrocima smrti.
11:56
And it's not just our honeybees.
238
716790
2189
A to nije slučaj samo sa medonosnim pčelama.
11:58
All of our beautiful wild species of bees
239
718979
2875
Sve naše predivne divlje vrste pčela
12:01
are at risk, including those tomato-pollinating bumblebees.
240
721854
4171
su u opasnosti, uključujući i bumbare, oprašivače paradajza.
12:06
These bees are providing backup for our honeybees.
241
726025
3551
Ove pčele obezbeđuju rezervu za naše medonosne pčele.
12:09
They're providing the pollination insurance
242
729576
2050
Obezbeđuju osiguranje oprašivanja
12:11
alongside our honeybees.
243
731626
1618
paralelno sa našim medonosnim pčelama.
12:13
We need all of our bees.
244
733244
2423
Potrebne su nam sve naše pčele.
12:15
So what are we going to do?
245
735667
2541
Pa šta ćemo uraditi?
12:18
What are we going to do about this big bee bummer
246
738208
2414
Šta ćemo uraditi u vezi sa ovom velikom pčelinjom neprijatnošću
12:20
that we've created?
247
740622
2263
koju smo mi stvorili?
12:22
It turns out, it's hopeful. It's hopeful.
248
742885
3817
Ispostavlja se da ima nade. Ima nade.
12:26
Every one of you out there can help bees
249
746702
3583
Svako od vas može pomoći pčelama
12:30
in two very direct and easy ways.
250
750285
4465
na dva veoma direktna i jednostavna načina.
12:34
Plant bee-friendly flowers,
251
754750
2955
Zasadite cveće koje je prijatelj pčelama,
12:37
and don't contaminate these flowers,
252
757705
2133
i nemojte pesticidima zagađivati to cveće,
12:39
this bee food, with pesticides.
253
759838
2662
tu hranu za pčele.
12:42
So go online and search for flowers
254
762500
3334
Pretražite na internetu koje je cveće
12:45
that are native to your area and plant them.
255
765834
3412
domaće u vašem području i zasadite ga.
12:49
Plant them in a pot on your doorstep.
256
769246
2123
Zasadite ga u saksiji na vašem kućnom pragu.
12:51
Plant them in your front yard, in your lawns,
257
771369
2574
Zasadite ga u vašem dvorištu, na vašim travnjacima,
12:53
in your boulevards.
258
773943
1530
u vašim ulicama.
12:55
Campaign to have them planted in public gardens,
259
775473
3613
Zauzmite se za sadnju cveća u javnim vrtovima,
12:59
community spaces, meadows.
260
779086
2581
otvorenim prostorima u vašoj zajednici, na livadama.
13:01
Set aside farmland.
261
781667
1749
Izdvojite poljoprivredno zemljište.
13:03
We need a beautiful diversity of flowers
262
783416
2700
Potrebna nam je predivna raznovrsnost cveća
13:06
that blooms over the entire growing season,
263
786116
2171
koje cveta tokom cele sezone,
13:08
from spring to fall.
264
788287
1894
od proleća do jeseni.
13:10
We need roadsides seeded in flowers for our bees,
265
790181
3698
Potrebni su nam prostori sa cvećem za naše pčele pored saobraćajnica,
13:13
but also for migrating butterflies and birds
266
793879
3454
ali takođe i za migracije leptira i ptica
13:17
and other wildlife.
267
797333
1976
i ostale prirodne vrste.
13:19
And we need to think carefully about putting back in
268
799309
3440
I trebalo bi pažljivo razmisliti o povratku biljaka
13:22
cover crops to nourish our soil
269
802749
3185
koje proizvode humus, da bi negovale naše tlo
13:25
and nourish our bees.
270
805934
3021
i negovale naše pčele.
13:28
And we need to diversify our farms.
271
808955
3263
I potrebna nam je raznolikost farmi.
13:32
We need to plant flowering crop borders and hedge rows
272
812218
3782
Potrebno nam je da zasadimo cvetajuće granice i ograde među usevima,
13:36
to disrupt the agricultural food desert
273
816000
3856
da bismo narušili pustinje hrane
13:39
and begin to correct the dysfunctional food system
274
819856
3290
i počeli da ispravljamo disfunkcionalni sistem ishrane
13:43
that we've created.
275
823146
2231
koji smo stvorili.
13:45
So maybe it seems like a really small countermeasure
276
825377
3384
Možda se čini kao zaista mala protivmera,
13:48
to a big, huge problem -- just go plant flowers --
277
828761
3018
naspram velikog, ogromnog problema - samo zasaditi cveće,
13:51
but when bees have access to good nutrition,
278
831779
3028
ali kad pčele imaju pristup dobroj ishrani,
13:54
we have access to good nutrition
279
834807
2186
mi imamo pristup dobroj ishrani
13:56
through their pollination services.
280
836993
2415
kroz njihovu uslugu oprašivanja.
13:59
And when bees have access to good nutrition,
281
839408
2536
I kada pčele imaju pristup dobroj ishrani,
14:01
they're better able to engage their own natural defenses,
282
841944
3599
sposobnije su da se angažuju u svojoj prirodnoj odbrani,
14:05
their healthcare,
283
845543
1418
svojoj zdravstvenoj zaštiti,
14:06
that they have relied on for millions of years.
284
846961
4098
na koju su se oslanjale milionima godina.
14:11
So the beauty of helping bees this way, for me,
285
851059
4849
Lepota u pomaganju pčelama na ovaj način, po meni,
14:15
is that every one of us needs to behave
286
855908
4450
je u tome što bi svako od nas trebalo da se ponaša
14:20
a little bit more like a bee society, an insect society,
287
860358
4780
malo više poput pčela u zajednici, u zajednici insekata,
14:25
where each of our individual actions
288
865138
3032
gde svaki od pojedinačnih postupaka
14:28
can contribute to a grand solution,
289
868170
3106
može da doprinese velikom rešenju,
14:31
an emergent property,
290
871276
1687
organizovanom sistemu,
14:32
that's much greater than the mere sum
291
872963
1981
koji je mnogo veći od prostog zbira
14:34
of our individual actions.
292
874944
2745
naših pojedinačnih postupaka.
14:37
So let the small act of planting flowers

Neka mali čin sadnje

and keeping them free of pesticides

i čuvanja cveća od pesticida
14:46
be the driver of large-scale change.

bude pokretač promene većih razmera.
14:50
On behalf of the bees, thank you.

U ime ovih pčela, hvala vam.

Chris Anderson: Thank you. Just a quick question.

Kris Anderson: Hvala. Samo jedno kratko pitanje.
15:01
The latest numbers on the die-off of bees,
299
901508
3156
Poslednje brojke o izumiranju pčela -
15:04
is there any sign of things bottoming out?
300
904664
2228
ima li ikakvih pokazatelja da se stvari privode kraju?
15:06
What's your hope/depression level on this?
301

Koje su Vaše nade i strahovi po ovom pitanju?
15:09
Maria Spivak: Yeah.

Maria Spivak: Da.
15:10
At least in the United States,
303
910285
1953
U Sjedinjenim Državama,
15:12
an average of 30 percent of all bee hives
304
912238
2352
prosečno 30 posto svih pčelinjih košnica
15:14
are lost every winter.
305
914590
2127
biva izgubljeno svake zime.
15:16
About 20 years ago,
306
916717
1805
Pre dvadesetak godina,
15:18
we were at a 15-percent loss.
307
918522
2336
imali smo gubitke od 15 procenata.
15:20
So it's getting precarious.
308
920858
2121
Tako da postaje nesigurno.
15:22
CA: That's not 30 percent a year, that's -- MS: Yes, thirty percent a year.
309
922979
2607
KA: To nije 30 procenata godišnje, to je - MS: Da, 30 posto godišnje.
15:25
CA: Thirty percent a year. MS: But then beekeepers are able to divide their colonies
310
925586
3554
KA: 30 posto godišnje. MS: Ali pčelari mogu da podele svoje kolonije,
15:29
and so they can maintain the same number,
311
929140
2650
i da tako zadrže isti broj,
15:31
they can recuperate some of their loss.
312
931790
2321
mogu povratiti neke svoje gubitke.
15:34
We're kind of at a tipping point.
313
934111
1618
Na neki način smo na prekretnici.
15:35
We can't really afford to lose that many more.
314
935729
2869
Zaista više ne možemo sebi priuštiti tako velike gubitke.
15:38
We need to be really appreciative
315
938598
1820
Moramo biti zaista zahvalni
15:40
of all the beekeepers out there. Plant flowers.
316
940418
3353
svim čuvarima pčela. Sadite cveće.
15:43
CA: Thank you.

KA: Hvala.
