Everything is covered in invisible ecosystems
0
1387
3719
一切事物均被肉眼不可見的生態系統覆蓋
00:17
made of tiny lifeforms: bacteria, viruses and fungi.
1
5106
4488
它由微小的生命組成：細菌、病毒和真菌
00:21
Our desks, our computers, our pencils, our buildings
2
9594
4104
我們的書桌、電腦、筆、建築
00:25
all harbor resident microbial landscapes.
3
13698
3456
全是微生物的棲息地
00:29
As we design these things, we could be thinking
4
17154
2760
當我們設計這些物品時，不妨思考一下
00:31
about designing these invisible worlds,
5
19914
2814
關於這些隱形世界的設計
00:34
and also thinking about how they interact
6
22728
2243
同時思考它們如何與
00:36
with our personal ecosystems.
7
24971
2756
我們個人的生態系統互動
00:39
Our bodies are home to trillions of microbes,
8
27727
3643
我們身體是億萬個微生物的住所
00:43
and these creatures define who we are.
9
31370
2360
這些生物定義了我們
00:45
The microbes in your gut can influence your weight and your moods.
10
33730
3878
腸道中的微生物可影響你的體重和心情
00:49
The microbes on your skin can help boost your immune system.
11
37608
3458
皮膚上的微生物有助於提升你的免疫系統
00:53
The microbes in your mouth can freshen your breath,
12
41066
3009
口中的微生物可使你口氣清新
00:56
or not,
13
44075
1472
或正好相反
00:57
and the key thing is that our personal ecosystems
14
45547
2979
最重要的是，我們個人的生態系統
01:00
interact with ecosystems on everything we touch.
15
48526
3068
與我們接觸的一切生態系統間的交互作用
01:03
So, for example, when you touch a pencil,
16
51594
1592
因此，例如，當你觸摸一支筆時
01:05
microbial exchange happens.
17
53186
2832
即發生微生物交換
01:08
If we can design the invisible ecosystems in our surroundings,
18
56018
4896
如果我們能設計周遭的隱形生態系統
01:12
this opens a path to influencing
19
60914
2623
將開啟一條途徑
01:15
our health in unprecedented ways.
20
63537
3391
以前所未有的方式影響我們的健康
01:18
I get asked all of the time from people,
21
66928
2464
經常有人問我
01:21
"Is it possible to really design microbial ecosystems?"
22
69392
4070
「設計微生物生態系統是否確實可行？」
01:25
And I believe the answer is yes.
23
73462
2548
我認為答案是肯定的
01:28
I think we're doing it right now,
24
76010
1925
我認為我們此刻正在進行這件事
01:29
but we're doing it unconsciously.
25
77935
3108
但是處於不自覺狀態
01:33
I'm going to share data with you
26
81043
1965
我想與大家分享一些資訊
01:35
from one aspect of my research focused on architecture
27
83008
3728
來自我對建築的研究之一
01:38
that demonstrates how, through both conscious
28
86736
3126
顯示我們如何藉由有意識
01:41
and unconscious design,
29
89862
2210
及無意識的設計
01:44
we're impacting these invisible worlds.
30
92072
3009
影響這些肉眼不可見的世界
01:47
This is the Lillis Business Complex at the University of Oregon,
31
95081
4229
這是奧勒岡大學 Lillis 商學綜合大樓
01:51
and I worked with a team of architects and biologists
32
99310
2684
我與一個由
建築師和生物學家組成的團隊合作
建築師和生物學家組成的團隊合作
01:53
to sample over 300 rooms in this building.
33
101994
4174
在這棟建築中的 300 多個房間取樣
01:58
We wanted to get something like a fossil record of the building,
34
106168
4010
我們希望得到
類似建築物的歷史紀錄
類似建築物的歷史紀錄
02:02
and to do this, we sampled dust.
35
110178
3310
為了達成這個目標，我們蒐集灰塵樣本
02:05
From the dust, we pulled out bacterial cells,
36
113488
3908
我們從灰塵中分離出細菌細胞
02:09
broke them open, and compared their gene sequences.
37
117396
3404
將它們打破，比較其中的基因序列
02:12
This means that people in my group
38
120800
1727
這意味著我的團隊成員
02:14
were doing a lot of vacuuming during this project.
39
122527
3313
在這個計畫中進行了大量吸塵工作
02:17
This is a picture of Tim, who,
40
125840
2520
照片中的人是 Tim
02:20
right when I snapped this picture, reminded me,
41
128360
2454
就在拍攝這張照片的當下，他提醒我說：
02:22
he said, "Jessica, the last lab group I worked in
42
130814
2570
「Jessica，在上個研究團隊中，
02:25
I was doing fieldwork in the Costa Rican rainforest,
43
133384
2971
我是在哥斯大黎加雨林進行田野調查，
02:28
and things have changed dramatically for me."
44
136355
3757
這和現在情況有著天壤之別。」
02:32
So I'm going to show you now first what we found in the offices,
45
140112
3752
因此我準備向大家展示
我們在辦公室中的第一項發現
我們在辦公室中的第一項發現
02:35
and we're going to look at the data through a visualization tool
46
143864
3076
我們將藉由某種視覺工具瀏覽這些資料
02:38
that I've been working on in partnership with Autodesk.
47
146940
3540
這是我和 Autodesk
（3D軟體設計公司）長期合作的成果
（3D軟體設計公司）長期合作的成果
02:42
The way that you look at this data is,
48
150480
2472
瀏覽資料的方法是
02:44
first, look around the outside of the circle.
49
152952
3578
先觀察圓圈外圍
02:48
You'll see broad bacterial groups,
50
156530
3022
你將看見許多不同的菌落
02:51
and if you look at the shape of this pink lobe,
51
159552
2840
如果觀察這個粉紅葉片狀圖形
02:54
it tells you something about the relative abundance of each group.
52
162392
3016
它將顯示每種菌落的相對數量
02:57
So at 12 o'clock, you'll see that offices have a lot of
53
165408
2496
因此在 12 點鐘方向，你看見辦公室存在許多
02:59
alphaproteobacteria, and at one o'clock
54
167904
2561
甲型變形菌，在 1 點鐘方向
03:02
you'll see that bacilli are relatively rare.
55
170465
4195
你看見桿菌數量十分稀少
03:06
Let's take a look at what's going on in different space types in this building.
56
174660
4363
我們看看建築中不同類型空間的情況
03:11
If you look inside the restrooms,
57
179023
2022
如果觀察休息室
03:13
they all have really similar ecosystems,
58
181045
3130
它們的生態系統均十分相似
03:16
and if you were to look inside the classrooms,
59
184175
2328
如果觀察教室
03:18
those also have similar ecosystems.
60
186503
2866
它們亦擁有相似的生態系統
03:21
But if you look across these space types,
61
189369
2414
但如果縱觀這些空間類型
03:23
you can see that they're fundamentally different
62
191783
2397
可看出它們彼此間
03:26
from one another.
63
194180
2155
截然不同
03:28
I like to think of bathrooms like a tropical rainforest.
64
196335
2993
我喜歡將浴室想成熱帶雨林
03:31
I told Tim, "If you could just see the microbes,
65
199328
2487
我對 Tim 說，「如果你能看見微生物
03:33
it's kind of like being in Costa Rica. Kind of."
66
201815
4039
大概就感覺像身處哥斯大黎加。」
03:37
And I also like to think of offices as being a temperate grassland.
67
205854
4523
我也喜歡將辦公室想成溫帶草原
03:42
This perspective is a really powerful one for designers,
68
210377
4212
這個觀點對設計師來說十分有用
03:46
because you can bring on principles of ecology,
69
214589
3427
因為你可以套用生態學原則
03:50
and a really important principle of ecology is dispersal,
70
218016
2912
生態學中一個
十分重要的原則就是傳播
十分重要的原則就是傳播
03:52
the way organisms move around.
71
220928
2727
即有機體的傳播方式
03:55
We know that microbes are dispersed around by people
72
223655
4184
我們知道微生物藉由人類
03:59
and by air.
73
227839
1071
和空氣傳播
04:00
So the very first thing we wanted to do in this building
74
228910
2837
因此我們希望在這棟建築中做的第一件事
04:03
was look at the air system.
75
231747
1853
就是觀察空氣系統
04:05
Mechanical engineers design air handling units
76
233600
3232
機械工程師設計空調系統
04:08
to make sure that people are comfortable,
77
236832
2192
確保人們感到舒適
04:11
that the air flow and temperature is just right.
78
239024
2553
空氣流通、氣溫恰到好處
04:13
They do this using principles of physics and chemistry,
79
241577
3544
他們利用物理和化學原理進行這項工作
04:17
but they could also be using biology.
80
245121
4374
但也可利用生物學
04:21
If you look at the microbes
81
249495
2112
如果觀察這棟建築中
04:23
in one of the air handling units in this building,
82
251607
3050
某個空調系統裡的微生物
04:26
you'll see that they're all very similar to one another.
83
254657
3991
將發現其中生態均十分相似
04:30
And if you compare this to the microbes
84
258648
3535
如果將它與
04:34
in a different air handling unit,
85
262183
2144
不同空調系統中的微生物比較
04:36
you'll see that they're fundamentally different.
86
264327
2712
將發現兩者截然不同
04:39
The rooms in this building are like islands in an archipelago,
87
267039
3551
這建築中的房間就像孤立群島中的島嶼
04:42
and what that means is that mechanical engineers
88
270590
2857
這意味著機械工程師
04:45
are like eco-engineers, and they have the ability
89
273447
2676
如同生態工程師有能力
04:48
to structure biomes in this building the way that they want to.
90
276123
5584
以他們想要的方式
建構這棟建築中的生物群落
建構這棟建築中的生物群落
04:53
Another facet of how microbes get around is by people,
91
281707
4108
另一個傳播微生物的方式是藉由人類
04:57
and designers often cluster rooms together
92
285815
3167
設計師通常將房間設計在一處
05:00
to facilitate interactions among people,
93
288982
2055
像是實驗室和辦公室
05:03
or the sharing of ideas, like in labs and in offices.
94
291037
3472
以促進人們的交流或分享看法
05:06
Given that microbes travel around with people,
95
294509
2674
考慮微生物隨著人們四處傳播
05:09
you might expect to see rooms that are close together
96
297183
2673
你或許預期相距不遠的房間
05:11
have really similar biomes.
97
299856
2255
存在十分相似的生物群落
05:14
And that is exactly what we found.
98
302111
2480
這正是我們發現的結果
05:16
If you look at classrooms right adjacent to one another,
99
304591
3167
如果觀察彼此相鄰的教室
05:19
they have very similar ecosystems,
100
307758
2199
它們擁有十分相似的生態系統
05:21
but if you go to an office
101
309957
3139
但如果觀察
05:25
that is a farther walking distance away,
102
313096
3048
與其相距甚遠的辦公室
05:28
the ecosystem is fundamentally different.
103
316144
2736
其中的生態系統則大不相同
05:30
And when I see the power that dispersal has
104
318880
4545
當我發現這些
05:35
on these biogeographic patterns,
105
323425
2280
生物地理學分佈模式的力量
05:37
it makes me think that it's possible
106
325705
2559
意識到或許可藉此
05:40
to tackle really challenging problems,
107
328264
3736
解決一些充滿挑戰的問題
05:44
like hospital-acquired infections.
108
332000
2461
例如：院內感染
05:46
I believe this has got to be, in part,
109
334461
2606
我認為其中部分原因必定在於
05:49
a building ecology problem.
110
337067
3643
建築物的生態問題
05:52
All right, I'm going to tell you one more story about this building.
111
340710
3792
好，我將告訴大家
更多關於這棟建築的故事
更多關於這棟建築的故事
05:56
I am collaborating with Charlie Brown.
112
344502
3465
我與 Charlie Brown 合作
05:59
He's an architect,
113
347967
1541
他是一名建築師
06:01
and Charlie is deeply concerned about global climate change.
114
349508
5333
Charlie 十分關切全球氣候變化
06:06
He's dedicated his life to sustainable design.
115
354841
2944
畢生致力於永續建築設計
06:09
When he met me and realized that it was possible for him
116
357785
3096
遇上我之後，他意識到自己有機會
06:12
to study in a quantitative way
117
360881
2176
以量化方式進行研究
06:15
how his design choices impacted
118
363057
2576
瞭解他的設計選擇如何影響
06:17
the ecology and biology of this building,
119
365633
2960
這棟建築的生態和生物系統
06:20
he got really excited, because it added a new dimension to what he did.
120
368593
4509
他十分興奮，
因為這為將他的工作提升到新層次
因為這為將他的工作提升到新層次
06:25
He went from thinking just about energy
121
373102
1868
他從僅思考能源問題
06:26
to also starting to think about human health.
122
374970
3488
轉為同時將人類健康納入考量
06:30
He helped design some of the air handling systems
123
378458
3861
他協助設計了一些
06:34
in this building and the way it was ventilated.
124
382319
2194
這棟建築的空調系統及通風方式
06:36
So what I'm first going to show you is
125
384513
2722
因此我首先要展示的是
06:39
air that we sampled outside of the building.
126
387235
3559
我們從戶外取樣的空氣
06:42
What you're looking at is a signature of bacterial communities
127
390794
4167
圖中顯示的是戶外空氣中的細菌群落
06:46
in the outdoor air, and how they vary over time.
128
394961
3976
以及它們如何隨時間改變
06:50
Next I'm going to show you what happened
129
398937
2988
接下來我將向大家展示
06:53
when we experimentally manipulated classrooms.
130
401925
3649
我們以教室進行實驗的情形
06:57
We blocked them off at night
131
405574
1615
我們於夜間將它關閉
06:59
so that they got no ventilation.
132
407189
2266
因此教室無法通風
07:01
A lot of buildings are operated this way,
133
409455
2177
許多建築採用這種方式
07:03
probably where you work,
134
411632
1751
或許你的工作地點正是如此
07:05
and companies do this to save money on their energy bill.
135
413383
2971
公司藉由這種方式節省電費
07:08
What we found is that these rooms remained relatively stagnant
136
416354
3927
我們發現這些房間的空氣幾乎靜止不動
07:12
until Saturday, when we opened the vents up again.
137
420281
3059
直到我們周六再次將它打開
07:15
When you walked into those rooms,
138
423340
1582
當你走進那些房間時
07:16
they smelled really bad,
139
424922
1975
氣味十分難聞
07:18
and our data suggests that it had something to do with
140
426897
3102
我們的資料顯示
07:21
leaving behind the airborne bacterial soup
141
429999
3067
這和留在空氣中的菌落有關
07:25
from people the day before.
142
433066
2679
來自前一天於此活動的人們
07:27
Contrast this to rooms
143
435745
2172
相較於
07:29
that were designed using a sustainable passive design strategy
144
437917
4281
採用被動式永續策略設計的房間
07:34
where air came in from the outside through louvers.
145
442198
3780
戶外空氣可由百葉窗進入
07:37
In these rooms, the air tracked the outdoor air relatively well,
146
445978
4797
這些房間的空氣成分與戶外空氣極為相似
07:42
and when Charlie saw this, he got really excited.
147
450775
2135
目賭這個結果時，Charlie非常興奮
07:44
He felt like he had made a good choice
148
452910
2111
他感到自己做了一個好選擇
07:47
with the design process
149
455021
1734
藉由設計過程
07:48
because it was both energy efficient
150
456755
2395
因為這不僅符合能源效率需求
07:51
and it washed away the building's resident microbial landscape.
151
459150
5289
也能帶走殘留在建築中的微生物
07:56
The examples that I just gave you are about architecture,
152
464439
3042
我剛剛展示的是關於建築的例子
07:59
but they're relevant to the design of anything.
153
467481

ABOUT THE SPEAKER
Jessica Green - Engineer and biodiversity scientistJessica Green wants people to understand the important role microbes play in every facet of our lives: climate change, building ecosystems, human health, even roller derby -- using nontraditional tools like art, animation and film to help people visualize the invisible world.
Why you should listen
Jessica Green, a TED2010 Fellow and TED2011 Senior Fellow, is an engineer and ecologist who specializes in biodiversity theory and microbial systems. As a professor at both the University of Oregon and the Santa Fe Institute, she is the founding director of the innovative Biology and the Built Environment (BioBE) Center that bridges biology and architecture.
Green envisions a future with genomic-driven approaches to architectural design that promote sustainability, human health and well-being. She is spearheading efforts to model buildings as complex ecosystems that house trillions of diverse microorganisms interacting with each other, with humans, and with their environment. This framework uses next-generation sequencing technology to characterize the “built environment microbiome” and will offer site-specific design solutions to minimize the spread of infectious disease and maximize building energy efficiency.
