This is our life with bees,
0
12883
3980
Ovo je naš život s pčelama,
00:16
and this is our life without bees.
1
16863
3723
a ovo je naš život bez njih.
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 cvijeća
00:25
and crops like alfalfa hay that feed our farm animals.
4
25863
3659
i usjeva poput alfalfa (lucerna) sijena koja hrane naše domaće životinje.
00:29
More than one third of the world's crop production
5
29522
2688
Više od trećine svjetske proizvodnje usjeva
00:32
is dependent on bee pollination.
6
32210
2782
ovisi o oprašivanju pomoću pčela.
00:34
But the ironic thing is that bees are not out there
7
34992
2837
No, ironično je to da pčele nisu ovdje
00:37
pollinating our food intentionally.
8
37829
2917
da bi namjerno oprašivale našu hranu.
00:40
They're out there because they need to eat.
9
40746
2871
One su ovdje jer moraju jesti.
00:43
Bees get all of the protein they need in their diet
10
43617
2719
Pčele dobivaju sve potrebne bjelančevine u njihovoj prehrani
00:46
from pollen
11
46336
1329
iz peludi
00:47
and all of the carbohydrates they need from nectar.
12
47665
2936
i sve potrebe ugljikohidrate iz nektara.
00:50
They're flower-feeders,
13
50601
1765
One se hrane cvijećem,
00:52
and as they move from flower to flower,
14
52366
1934
i kako lete s cvijeta na cvijet,
00:54
basically on a shopping trip at the local floral mart,
15
54300
3471
kao da odlaze u kupovinu u obližnju cvjećarnicu
00:57
they end up providing this valuable pollination service.
16
57771
4455
na kraju nam pružaju dragocjeno oprašivanje.
01:02
In parts of the world where there are no bees,
17
62226
2520
U dijelovima svijeta gdje nema pčela
01:04
or where they plant varieties that are not attractive to bees,
18
64746
2906
ili gdje se sade vrste bilja koje pčelama nisu privlačne,
01:07
people are paid to do the business of pollination by hand.
19
67652
4206
ljudima se plaća da obavljaju oprašivanje rukama.
01:11
These people are moving pollen from flower to flower
20
71858
3684
Ti ljudi raspršuju pelud s cvijeta na cvijet
01:15
with a paintbrush.
21
75542
1899
pomoću kista.
01:17
Now this business of hand pollination
22
77441
2446
Ovakav posao ručnog oprašivanja
01:19
is actually not that uncommon.
23
79887
2086
zapravo i nije tako neuobičajen.
01:21
Tomato growers often pollinate their tomato flowers
24
81973
3352
Uzgajivači rajčice često oprašuju svoje cvjetove rajčica
01:25
with a hand-held vibrator.
25
85325
2657
ručnim vibratorom.
01:27
Now this one's the tomato tickler. (Laughter)
26
87982
3944
Ovo je škakljač rajčica. (Smijeh)
01:31
Now this is because the pollen within a tomato flower
27
91926
5280
To je zbog razloga što je pelud u cvijetu rajčice
01:37
is held very securely within
28
97206
1780
jako dobro zaštićena
01:38
the male part of the flower, the anther,
29
98986
2500
u muškom dijelu cvijeta, prašniku,
01:41
and the only way to release this pollen is to vibrate it.
30
101486
3374
i jedini način da se pelud oslobodi je da ga se protrese.
01:44
So bumblebees are one of the few kinds of bees in the world
31
104860
3686
Bumbari su jedni od rijetkih vrsta pčela na svijetu
01:48
that are able to hold onto the flower and vibrate it,
32
108546
3123
koji se mogu primiti na cvijet i vibrirati ga,
01:51
and they do this by shaking their flight muscles
33
111669
2592
a to čine tako da tresu svoje mišiće za letenje
01:54
at a frequency similar to the musical note C.
34
114261
4552
frekvencijom koja je slična glazbenoj noti C.
01:58
So they vibrate the flower, they sonicate it,
35
118813
2586
Tako oni tresu cvijet, soniciraju ga,
02:01
and that releases the pollen in this efficient swoosh,
36
121399
3047
što oslobađa pelud u učinkovitom zamahu,
02:04
and the pollen gathers all over the fuzzy bee's body,
37
124446
2739
a pelud se skuplja po cijelom pahuljastom tijelu pčele,
02:07
and she takes it home as food.
38
127185
2497
koju pčela nosi doma kao hranu.
02:09
Tomato growers now put bumblebee colonies
39
129682
2841
Uzgajivači rajčica sada smještaju kolonije bumbara
02:12
inside the greenhouse to pollinate the tomatoes
40
132523
2531
unutar plastenika kako bi oprašivali rajčice,
02:15
because they get much more efficient pollination
41
135054
2363
jer dobivaju puno učinkovitije oprašivanje
02:17
when it's done naturally
42
137417
1495
kada se to obavlja prirodim putem,
02:18
and they get better quality tomatoes.
43
138912
3562
a dobivaju i kvalitetnije rajčice.
02:22
So there's other, maybe more personal reasons,
44
142474
3587
Postoje i drugi, možda osobniji razlozi
02:26
to care about bees.
45
146061
1423
zašto bismo trebali brinuti o pčelama.
02:27
There's over 20,000 species of bees in the world,
46
147484
4172
Na svijetu je preko 20.000 vrsta pčela
02:31
and they're absolutely gorgeous.
47
151656
3006
i jednostavno su prekrasne.
02:34
These bees spend the majority of their life cycle
48
154662
2619
Te pčele provedu većinu svog životnog ciklusa
02:37
hidden in the ground or within a hollow stem
49
157281
2820
skrivene u zemlji ili u šupljem deblu
02:40
and very few of these beautiful species
50
160101
2700
i jako malo pripadnika ovih prekrasnih vrsta
02:42
have evolved highly social behavior like honeybees.
51
162801
3433
su razvile visoko društveno ponašanje poput pčela medarica.
02:46
Now honeybees tend to be the charismatic representative
52
166234
3620
Pčele medarice nerijetko su karizmatične predstavnice
02:49
for the other 19,900-plus species
53
169854
3169
svih ostalih 19.900 i više vrsta pčela,
02:53
because there's something about honeybees
54
173023
2641
jer ima nešto kod tih pčela medarica
02:55
that draws people into their world.
55
175664
2849
što privlači ljude u njihov svijet.
02:58
Humans have been drawn to honeybees
56
178513
2447
Pčele medarice privlače ljude
03:00
since early recorded history,
57
180960
1716
od najranijih vremena,
03:02
mostly to harvest their honey,
58
182676
1476
uglavnom kako bi pobrali njihov med,
03:04
which is an amazing natural sweetener.
59
184152
3459
koji je nevjerojatni prirodni zaslađivač.
03:07
I got drawn into the honeybee world
60
187611
1788
Svijet pčela medarica privukao me
03:09
completely by a fluke.
61
189399
2085
sasvim slučajno.
03:11
I was 18 years old and bored,
62
191484
2322
Imala sam 18 godina i bilo mi je dosadno,
03:13
and I picked up a book in the library on bees
63
193806
2862
i u knjižnici sam posudila knjigu o pčelama,
03:16
and I spent the night reading it.
64
196668
2242
te provela noć čitajući je.
03:18
I had never thought about insects
65
198910
1927
Nikad do tad nisam razmišljala o tome kako insekti
03:20
living in complex societies.
66
200837
1723
žive u složenim društvima.
03:22
It was like the best of science fiction come true.
67
202560
3402
Bilo je kao da se ono najbolje od znanstvene fantastike ostvarilo.
03:25
And even stranger, there were these people,
68
205962
2894
Čak i neobičnije. Tu su bili neki ljudi,
03:28
these beekeepers, that loved their bees like they were family,
69
208856
3991
pčelari, koji vole svoje pčele kao da su dio obitelji,
03:32
and when I put down the book, I knew I had to see this for myself.
70
212847
3303
i kad sam odložila knjigu, znala sam da se moram sama u to uvjeriti.
03:36
So I went to work for a commercial beekeeper,
71
216150
2485
Tako da sam počela raditi za komercijalnog pčelara,
03:38
a family that owned 2,000 hives of bees in New Mexico.
72
218635
4197
jednu obitelj koja je posjedovala 2.000 košnica u Novom 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
Pčele medarice možemo smatrati super organizmom,
03:49
where the colony is the organism
75
229553
2156
gdje 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
Ovo društvo nema središnju upravu.
04:00
Nobody's in charge.
79
240701
1596
Nitko ne vodi.
04:02
So how they come to collective decisions,
80
242297
2345
Tako da način na koji dolaze do zajedničkih odluka,
04:04
and how they allocate their tasks and divide their labor,
81
244642
2980
i način na koji dodjeljuju zadatke i dijele svoj posao,
04:07
how they communicate where the flowers are,
82
247622
2482
i kako priopćuju gdje se nalazi cvijeće,
04:10
all of their collective social behaviors are mindblowing.
83
250104
4164
kompletno njihovo zajedničko društveno ponašanje je zapanjujuće.
04:14
My personal favorite, and one that I've studied for many years,
84
254268
3768
Meni osobno najdraži, koji sam mnogo godina proučavala,
04:18
is their system of healthcare.
85
258036
1945
je njihov sustav zdravstvene skrbi.
04:19
So bees have social healthcare.
86
259981
3485
I pčele imaju socijalnu zdravstvenu skrb.
04:23
So in my lab, we study how bees keep themselves healthy.
87
263466
4270
Tako u mom laboratoriju proučavamo kako pčele čuvaju svoje zdravlje.
04:27
For example, we study hygiene,
88
267736
2339
Na primjer, proučavamo higijenu,
04:30
where some bees are able to locate and weed out
89
270075
2886
kako neke pčele mogu pronaći i odstraniti
04:32
sick individuals from the nest, from the colony,
90
272961
3167
bolesne jedinke iz gnijezda, iz kolonije,
04:36
and it keeps the colony healthy.
91
276128
2464
i to održava koloniju zdravom.
04:38
And more recently, we've been studying resins
92
278592
3427
U novije vrijeme proučavamo smolu
04:42
that bees collect from plants.
93
282019
2109
koju pčele skupljaju iz biljaka.
04:44
So bees fly to some plants and they scrape
94
284128
3183
Tako pčele lete do nekih biljaka i strugaju
04:47
these very, very sticky resins off the leaves,
95
287311
2656
tu vrlo ljepljivu smolu s lišća,
04:49
and they take them back to the nest
96
289967
1578
i nose je nazad u gnijezdo
04:51
where they cement them into the nest architecture
97
291545
2866
gdje je učvršćuju u arhitekturu gnijezda,
04:54
where we call it propolis.
98
294411
2525
što mi nazivamo propolis.
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
To je prirodni antibiotik.
05:03
It kills off bacteria and molds and other germs
101
303502
3179
Ubija bakterije i plijesni i druge bacile
05:06
within the colony,
102
306681
1602
unutar kolonije,
05:08
and so it bolsters the colony health and their social immunity.
103
308283
3963
i tako održavaju zdravlje kolonije i njihov društveni imunitet.
05:12
Humans have known about the power of propolis
104
312246
3291
Ljudi su upoznati sa djelotvornostima propolisa
05:15
since biblical times.
105
315537
1647
još od biblijskih vremena.
05:17
We've been harvesting propolis out of bee colonies
106
317184
3350
Prikupljamo propolis iz pčelinjih kolonija
05:20
for human medicine,
107
320534
2052
za ljudsku medicinu,
05:22
but we didn't know how good it was for the bees.
108
322586
3664
ali nismo znali koliko je on dobar za pčele.
05:26
So honeybees have these remarkable natural defenses
109
326250
4053
Pčele medarice tako imaju čudesnu prirodnu obranu
05:30
that have kept them healthy and thriving
110
330303
2689
koja ih je održavala zdravima i uspješnima
05:32
for over 50 million years.
111
332992
4257
preko 50 milijuna godina.
05:37
So seven years ago, when honeybee colonies
112
337249
3349
I tako prije sedam godina, kada je bilo objavljeno
05:40
were reported to be dying en masse,
113
340598
1799
da kolonije pčela medarica masovno izumiru,
05:42
first in the United States,
114
342397
1972
prvo u SAD-u,
05:44
it was clear that there was something really, really wrong.
115
344369
3813
bilo je jasno da nešto nikako nije u redu.
05:48
In our collective conscience, in a really primal way,
116
348182
3486
U našoj kolektivnoj svijesti, na posve iskonski način,
05:51
we know we can't afford to lose bees.
117
351668
3186
znamo da si ne možemo priuštiti gubitak pčela.
05:54
So what's going on?
118
354854
3115
Pa što se onda događa?
05:57
Bees are dying from multiple and interacting causes,
119
357969
4089
Pčele umiru iz višestrukih i uzajamnih 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
Zaključak je taj da
06:06
bees dying reflects a flowerless landscape
122
366393
4052
umiranje pčela odražava krajolik bez cvijeća,
06:10
and a dysfunctional food system.
123
370445
3489
i disfunkcionalni sustav hrane.
06:13
Now we have the best data on honeybees,
124
373934
1992
Imamo najbolje podatke o pčelama medaricama,
06:15
so I'll use them as an example.
125
375926
1856
pa ću ih iskoristiti kao primjer.
06:17
In the United States, bees in fact have been
126
377782
3493
U SAD-u broj pčela je zapravo
06:21
in decline since World War II.
127
381275
2864
u opadanju od Drugog svjetskog rata.
06:24
We have half the number of managed hives
128
384139
2274
Danas u SAD-u imamo 50% manje košnica
06:26
in the United States now compared to 1945.
129
386413
3014
nego što smo imali 1945. godine.
06:29
We're down to about two million hives of bees, we think.
130
389427
3651
Pretpostavljamo da je broj košnica pao na oko 2 milijuna.
06:33
And the reason is, after World War II,
131
393078
2746
Razlog tome je taj što smo, poslije Drugog svjetskog rata,
06:35
we changed our farming practices.
132
395824
3328
promijenili poljoprivrednu praksu.
06:39
We stopped planting cover crops.
133
399152
2839
Prestali smo saditi pokrovne usjeve.
06:41
We stopped planting clover and alfalfa,
134
401991
2743
Prestali smo saditi djetelinu i lucernu,
06:44
which are natural fertilizers that fix nitrogen in the soil,
135
404734
3846
koji su prirodna gnojiva koja unose dušik u tlo,
06:48
and instead we started using synthetic fertilizers.
136
408580
3604
a umjesto toga smo počeli koristiti umjetna gnojiva.
06:52
Clover and alfalfa are highly nutritious food plants for bees.
137
412184
5544
Djetelina i lucerna su visoko hranjiva biljna hrana za pčele.
06:57
And after World War II, we started using herbicides
138
417728
3454
Poslije Drugog svjetskog rata, počeli smo koristiti herbicide
07:01
to kill off the weeds in our farms.
139
421182
2497
kako bismo iskorijenili korov s naših farmi.
07:03
Many of these weeds are flowering plants
140
423679
2781
Mnogi od tih korova su kritosjemenjače
07:06
that bees require for their survival.
141
426460
2933
koje su pčelama potrebne da bi preživjele.
07:09
And we started growing larger and larger crop monocultures.
142
429393
5571
I počeli smo uzgajati sve veće monokulturne usjeve.
07:14
Now we talk about food deserts,
143
434964

Danas govorimo o područjima pogođenima nestašicom hrane,
07:17
places in our cities, neighborhoods that have no grocery stores.
144
437529
4250
mjestima u našim gradovima, susjedstvima gdje nema dućana mješovite robe.
07:21
The very farms that used to sustain bees
145
441779
4043
Iste farme koje su nekoć uzdržavale pčele,
07:25
are now agricultural food deserts,
146
445822
2756
danas su poljoprivredne pustinje hrane
07:28
dominated by one or two plant species
147
448578
2423
u kojima prevladavaju jedna ili dvije biljne vrste
07:31
like corn and soybeans.
148
451001
2589
poput kukuruza ili sojinog graha.
07:33
Since World War II, we have been systematically
149
453590
2905
Od Drugog svjetskog rata, sustavno
07:36
eliminating many of the flowering plants
150
456495
2899
odstranjujemo mnoge kritosjemenjače
07:39
that bees need for their survival.
151
459394
3552
koje pčele trebaju kako bi preživjele.
07:42
And these monocultures extend even to crops
152
462946
2898
Te monokulture se šire čak i na usjeve
07:45
that are good for bees, like almonds.
153
465844
2547
koji su dobri za pčele, poput badema.
07:48
Fifty years ago, beekeepers would take a few colonies,
154
468391
3986
Prije pedeset godina, pčelari bi uzeli par 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
all i zato što je pelud iz bademova cvijeta
07:59
is really high in protein. It's really good for bees.
157
479320
4180
jako bogata bjelančevinama. Jako je dobra za pčele.
08:03
Now, the scale of almond monoculture
158
483500
3997
Sad, razmjer monokulture badema
08:07
demands that most of our nation's bees,
159
487497
2552
zahtijeva da većina pčela u našoj zemlji,
08:10
over 1.5 million hives of bees,
160
490049
2736
preko 1.5 milijuna pčelinjih košnica,
08:12
be transported across the nation
161
492785
2992
bude prenesena preko cijele zemlje
08:15
to pollinate this one crop.
162
495777
2351
kako bi se oprašio ovaj jedan usjev.
08:18
And they're trucked in in semi-loads,
163
498128
2645
Utovaruju se na šlepere,
08:20
and they must be trucked out,
164
500773
2330
i mora ih se i istovariti,
08:23
because after bloom, the almond orchards
165
503103
2739
budući da nakon cvjetanja, voćnjaci badema
08:25
are a vast and flowerless landscape.
166
505842
5210
postaju golema područja bez cvijeća.
08:31
Bees have been dying over the last 50 years,
167
511052
2466
Pčele izumiru u zadnjih 50 godina,
08:33
and we're planting more crops that need them.
168
513518
3805
a mi sadimo više usjeva za koje su pčele potrebne.
08:37
There has been a 300 percent increase in crop production
169
517323
4184
Proizvodnja usjeva koji zahtijevaju oprašivanje
08:41
that requires bee pollination.
170
521507
3804
pomoću pčela porasla je 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 svjetskog rata, počeli smo koristiti pesticide
08:51
on a large scale, and this became necessary
173
531681
2564
u velikim količinama, a to je postalo potrebno
08:54
because of the monocultures that put out a feast
174
534245
3794
zbog monokultura koje su privlačile
08:58
for crop pests.
175
538039
2293
nametnike usjeva.
09:00
Recently, researchers from Penn State University
176
540332
2941
U posljednje vrijeme, istraživači sa sveučilišta Penn State
09:03
have started looking at the pesticide residue
177
543273
3297
počeli su promatrati zaostatak pesticida
09:06
in the loads of pollen that bees carry home as food,
178
546570
3550
u hrpama peludi koje pčele donose kući kao hranu,
09:10
and they've found that every batch of pollen
179
550120
3591
i otkrili su da svaka mjerica peludi
09:13
that a honeybee collects
180
553711
2007
koju pčela medarica skupi
09:15
has at least six detectable pesticides in it,
181
555718
3787
sadrži bar šest prepoznatljivih pesticida,
09:19
and this includes every class of insecticides,
182
559505
4043
što uključuje svaku vrstu insekticida,
09:23
herbicides, fungicides,
183
563548
2843
herbicida, fungicida,
09:26
and even inert and unlabeled ingredients
184
566391
3580
pa čak i inertnih neimenovanih sastojaka,
09:29
that are part of the pesticide formulation
185
569971
2572
koji su dio formulacije pesticida,
09:32
that can be more toxic than the active ingredient.
186
572543
4222
koji mogu biti otrovniji od aktivnog sastojka.
09:36
This small bee is holding up a large mirror.
187
576765
5642
Ova malena pčela drži veliko zrcalo.
09:42
How much is it going to take to contaminate humans?
188
582407
4448
Koliko će biti potrebno da zarazi ljude?
09:46
One of these class of insecticides,
189
586855
2980
Jedna od ovih vrsta insekticida,
09:49
the neonicontinoids,
190
589835
1375
neonikotinoidi,
09:51
is making headlines around the world right now.
191
591210
2260
danas je česta tema novina diljem svijeta.
09:53
You've probably heard about it.
192
593470
1446
Vjerojatno ste čuli za to.
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
Prolazi kroz biljku tako da nametnik usjeva,
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
zagrize u biljku
10:02
and get a lethal dose and die.
197
602810
3340
dobije smrtonosnu dozu i umre.
10:06
If one of these neonics, we call them,
198
606150
2823
Ako se jedan od ovih neonikotinoida
10:08
is applied in a high concentration,
199
608973
2454
upotrijebi u visokoj koncentraciji,
10:11
such as in this ground application,
200
611427
2262
kao u ovoj animaciji,
10:13
enough of the compound moves through the plant
201
613689
2468
dovoljno spojeva prolazi kroz biljku
10:16
and gets into the pollen and the nectar,
202
616157
2212
u ulazi u pelud i nektar
10:18
where a bee can consume, in this case,
203
618369
2104
gdje pčela, u ovom slučaju, može pojesti
10:20
a high dose of this neurotoxin
204
620473
3018
visoku dozu ovog neurotoksina
10:23
that makes the bee twitch and die.
205
623491
4149
od čega se počne grčiti i ugine.
10:27
In most agricultural settings, on most of our farms,
206
627640
3173
Na većini poljoprivrednih zemljišta, na većini naših farmi,
10:30
it's only the seed that's coated with the insecticide,
207
630813
3943
jedino je sjeme obloženo insekticidom,
10:34
and so a smaller concentration moves through the plant
208
634756
2991
tako da manja koncentracija prolazi proz biljku
10:37
and gets into the pollen and nectar,
209
637747
1968
i ulazi u pelud i nektar,
10:39
and if a bee consumes this lower dose,
210
639715
2543
i ako pčela pojede ovu manju dozu,
10:42
either nothing happens
211
642258
1342
ili se ne dogodi ništa,
10:43
or the bee becomes intoxicated and disoriented
212
643600
3588
ili je pčela opijena i dezorijentirana
10:47
and she may not find her way home.
213
647188
3712
i možda se neće znati vratiti kući.
10:50
And on top of everything else, bees have
214
650900
2132
A povrh svega, pčele imaju
10:53
their own set of diseases and parasites.
215
653032
2268
i vlastite bolesti i nametnike.
10:55
Public enemy number one for bees is this thing.
216
655300
2860
Glavni neprijatelj pčela je ovo.
10:58
It's called varroa destructor.
217
658160
2305
Zove se varroa destructor.
11:00
It's aptly named.
218
660465
1104
Naziv joj je prikladan.
11:01
It's this big, blood-sucking parasite
219
661569
2612
To je veliki nametnik koji siše krv,
11:04
that compromises the bee's immune system
220
664181
2374
ugrožava pčelinji imuno sustav
11:06
and circulates viruses.
221
666555
2771
i širi viruse.
11:09
Let me put this all together for you.
222
669326
2929
Dopustite mi da vam to predočim.
11:12
I don't know what it feels like to a bee
223
672255
2667
Ne znam kako je to biti pčela,
11:14
to have a big, bloodsucking parasite running around on it,
224
674922
2701
imati na sebi velikog nametnika 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 pčeli kada ima virus,
11:20
but I do know what it feels like when I have a virus, the flu,
226
680762
5128
ali znam kako se ja osjećam kada imam virus, gripu,
11:25
and I know how difficult it is for me to get
227
685890
3232
i znam koliko mi je teško otići
11:29
to the grocery store to get good nutrition.
228
689122
2789
u dućan mješovite robe po dobru hranu.
11:31
But what if I lived in a food desert?
229
691911
3046
No, što bi bilo da živim u predjelu bez hrane?
11:34
And what if I had to travel a long distance
230
694957
2495
I što bi bilo da moram prijeći veliku udaljenost
11:37
to get to the grocery store,
231
697452
1873
kako bih došla do dućana,
11:39
and I finally got my weak body out there
232
699325
2874
i kad bih konačno dovukla svoje slabo tijelo do tamo,
11:42
and I consumed, in my food,
233
702199
2144
i kroz svoju hranu unijela
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 se ne bih znala vratiti kući?
11:49
And this is what we mean by multiple
236
709900
3187
Upravo na to mislimo kada govorimo o višestrukim
11:53
and interacting causes of death.
237
713087
3703
i uzajamnim uzrocima ugibanja.
11:56
And it's not just our honeybees.
238
716790
2189
I ne radi se samo o našim pčelama medaricama.
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 ugrožene, uključujući i one bumbare koji oprašuju rajčice.
12:06
These bees are providing backup for our honeybees.
241
726025
3551
Te pčele su rezerva našim pčelama medaricama.
12:09
They're providing the pollination insurance
242
729576
2050
One osiguravaju oprašivanje
12:11
alongside our honeybees.
243
731626
1618
pored naših pčela medarica.
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
I što ćemo onda učiniti?
12:18
What are we going to do about this big bee bummer
246
738208
2414
Što ćemo učiniti u vezi ove velike pčelinje frke
12:20
that we've created?
247
740622
2263
koju smo stvorili?
12:22
It turns out, it's hopeful. It's hopeful.
248
742885
3817
Ispada da ipak ima nade. Ima nade.
12:26
Every one of you out there can help bees
249
746702
3583
Svaki od vas ovdje može pomoći pčelama
12:30
in two very direct and easy ways.
250
750285
4465
na dva vrlo izravna i laka načina.
12:34
Plant bee-friendly flowers,
251
754750
2955
Sadite cvijeće koje vole pčele,
12:37
and don't contaminate these flowers,
252
757705
2133
i nemojte kontaminirati to cvijeće,
12:39
this bee food, with pesticides.
253
759838
2662
tu hranu za pčele, pesticidima.
12:42
So go online and search for flowers
254
762500
3334
Otiđite na Internet i potražite cvijeće
12:45
that are native to your area and plant them.
255
765834
3412
koje je iz vaše sredine i posadite ga.
12:49
Plant them in a pot on your doorstep.
256
769246
2123
Posadite ga u lončanici ispred vašeg ulaza u kuću.
12:51
Plant them in your front yard, in your lawns,
257
771369
2574
Posadite ga u vašem vrtu, na vašem travnjaku,
12:53
in your boulevards.
258
773943
1530
u vašim bulevarima.
12:55
Campaign to have them planted in public gardens,
259
775473
3613
Pokrenite kampanju da se ono posadi u javnim vrtovima,
12:59
community spaces, meadows.
260
779086
2581
komunalnim prostorima, livadama,
13:01
Set aside farmland.
261
781667
1749
izdvojenim poljoprivrednim površinama.
13:03
We need a beautiful diversity of flowers
262
783416
2700
Trebamo predivnu raznolikost cvijeća
13:06
that blooms over the entire growing season,
263
786116
2171
koje cvate tijekom cijelog vegetacijskog razdoblja,
13:08
from spring to fall.
264
788287
1894
od proljeća do jeseni.
13:10
We need roadsides seeded in flowers for our bees,
265
790181
3698
Trebamo cvijeće za naše pčele posađeno uz cestu,
13:13
but also for migrating butterflies and birds
266
793879
3454
ali i za migrirajuće leptire i ptice
13:17
and other wildlife.
267
797333
1976
i druge životinje.
13:19
And we need to think carefully about putting back in
268
799309
3440
Trebamo pažljivo razmisliti o tome da vratimo
13:22
cover crops to nourish our soil
269
802749
3185
pokrovne usjeve kako bismo nahranili našu zemlju
13:25
and nourish our bees.
270
805934
3021
i naše pčele.
13:28
And we need to diversify our farms.
271
808955
3263
I trebamo učiniti naše farme raznolikijima.
13:32
We need to plant flowering crop borders and hedge rows
272
812218
3782
Trebamo saditi granice od cvjetnih usjeva i živicu
13:36
to disrupt the agricultural food desert
273
816000
3856
kako bismo onemogućili razvijanje poljoprivredno siromašnih područja
13:39
and begin to correct the dysfunctional food system
274
819856
3290
i počeli ispravljati disfunkcionalni sustav hrane
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 to čini kao jako malena protumjera
13:48
to a big, huge problem -- just go plant flowers --
277
828761
3018
velikom, golemom problemu -- samo sadite cvijeće --
13:51
but when bees have access to good nutrition,
278
831779
3028
ali kada pčele imaju pristup dobroj hrani,
13:54
we have access to good nutrition
279
834807
2186
i mi imamo pristup dobroj hrani
13:56
through their pollination services.
280
836993
2415
kroz njihovo oprašivanje.
13:59
And when bees have access to good nutrition,
281
839408
2536
A kada pčele imaju pristup dobroj hrani,
14:01
they're better able to engage their own natural defenses,
282
841944
3599
mogu bolje upravljati svojom prirodnom zaštitom,
14:05
their healthcare,
283
845543
1418
svojom zdravstvenom skrbi,
14:06
that they have relied on for millions of years.
284
846961
4098
na koju su se oslanjali milijunima godina.
14:11
So the beauty of helping bees this way, for me,
285
851059
4849
Tako da je ljepota pomaganju pčela na ovaj način, za mene,
14:15
is that every one of us needs to behave
286
855908
4450
u tome da se svatko od nas treba malo više
14:20
a little bit more like a bee society, an insect society,
287
860358
4780
ponašati kao pčelinje društvo, društvo insekata,
14:25
where each of our individual actions
288
865138
3032
gdje svako naše pojedinačno djelo
14:28
can contribute to a grand solution,
289
868170
3106
može doprinijeti velikom rješenju,
14:31
an emergent property,
290

that's much greater than the mere sum

koje je mnogo veće od pukog zbroja
14:34
of our individual actions.

naših pojedinačnih djela.
14:37
So let the small act of planting flowers

Tako neka maleno djelo sadnje cvijeća
14:42
and keeping them free of pesticides

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

bude pokretač velike promjene.
14:50
On behalf of the bees, thank you.
296

U ime pčela, hvala vam.

Chris Anderson: Thank you. Just a quick question.

Chris Anderson: Hvala Vam. Samo brzo pitanje.
15:01
The latest numbers on the die-off of bees,

Što se tiče najnovijih podataka o izumiranju pčela,
15:04
is there any sign of things bottoming out?
300
904664
2228
ima li naznake da će broj pčela dosegnuti dno i početi opet rasti?
15:06
What's your hope/depression level on this?

Koja je mjera vaše nade i brige vezane uz ovo?
15:09
Maria Spivak: Yeah.

Maria Spivak: Da.
15:10
At least in the United States,
303
910285
1953
Barem u SAD-u,
15:12
an average of 30 percent of all bee hives
304
912238
2352
prosječno 30 posto svih pčelinjih košnica
15:14
are lost every winter.
305
914590
2127
je izgubljeno svake zime.
15:16
About 20 years ago,
306
916717
1805
Prije otprilike 20 godina,
15:18
we were at a 15-percent loss.
307
918522
2336
gubitak je iznosio 15 posto.
15:20
So it's getting precarious.
308
920858
2121
Tako da postaje neizvjesno.
15:22
CA: That's not 30 percent a year, that's -- MS: Yes, thirty percent a year.
309
922979
2607
CA: To nije 30 posto na godinu, to je -- MS: Da, 30 posto na godinu.
15:25
CA: Thirty percent a year. MS: But then beekeepers are able to divide their colonies
310
925586
3554
CA: 30 posto na godinu. MS: No, pčelari onda mogu podijeliti svoje kolonije
15:29
and so they can maintain the same number,
311
929140
2650
i tako održati isti broj,
15:31
they can recuperate some of their loss.
312
931790
2321
mogu nadoknaditi dio gubitka.
15:34
We're kind of at a tipping point.
313
934111
1618
Mi smo jedna vrsta prekretnice.
15:35
We can't really afford to lose that many more.
314
935729
2869
Ne možemo si priuštiti još veći gubitak pčela.
15:38
We need to be really appreciative
315
938598
1820
Trebamo biti zaista zahvalni
15:40
of all the beekeepers out there. Plant flowers.
316
940418
3353
svim pčelarima. Sadite cvijeće.
15:43
CA: Thank you.
317
943771

CA: Hvala Vam.
