在哈德遜發現紐約港400年後，Eric Sanderson 向我們講述了他是如何製作了一張極其精確的3D地圖：曼哈頓在成為城市之前的生態圖，裡面有山丘，有河流還有野生動植物，當時的時代廣場還是一片荒蕪濕地。

Cities, past and future.

3000
3000
城市的過去和未來。
00:21
In Oxford, perhaps we can use Lewis Carroll
2
6000
4000
在牛津，我們或許可以將路易斯．卡洛爾
00:25
and look in the looking glass that is New York City
3
10000
3000
做為借鏡，藉由紐約市反映出的現況，
00:28
to try and see our true selves,
4
13000
3000
並試著看清我們真實的自我，
00:31
or perhaps pass through to another world.
5
16000
3000
或許還能穿越到另一個世界。
00:34
Or, in the words of F. Scott Fitzgerald,
6
19000
3000
或者，就像史考特‧費茲傑羅所說的，
00:37
"As the moon rose higher,
7
22000
2000
“當明月冉冉升起時，
00:39
the inessential houses began to melt away
8
24000
3000
那些微不足道的房屋慢慢消逝，
00:42
until gradually I became aware of the old island
9
27000
2000
直到我逐漸意識到這座古老島嶼
00:44
here that once flowered for Dutch sailors' eyes,
10
29000
3000
當年曾讓荷蘭水手驚艷，
00:47
a fresh green breast of the new world."
11
32000
3000
是新世界中的一塊翠綠寶石。"
00:50
My colleagues and I have been working for 10 years
12
35000
2000
我和我的同事花了10年功夫
00:52
to rediscover this lost world
13
37000
3000
去重現這個消失的世界，
00:55
in a project we call The Mannahatta Project.
14
40000
3000
這則是“Mannahatta計畫”的主要任務。
00:58
We're trying to discover what Henry Hudson would have seen
15
43000
2000
我們試圖再現Henry Hudson
01:00
on the afternoon of September 12th, 1609,
16
45000
3000
在1609年9月12日下午，
01:03
when he sailed into New York harbor.
17
48000
3000
駕船駛入紐約港時看到的景象。
01:06
And I'd like to tell you the story in three acts,
18
51000
2000
我把故事分成三個部分，
01:08
and if I have time still, an epilogue.
19
53000
3000
如果講完還有時間，就再做個總結。
01:11
So, Act I: A Map Found.
20
56000
2000
第一部分：發現地圖。
01:13
So, I didn't grow up in New York.
21
58000
2000
我不是在紐約長大的。
01:15
I grew up out west in the Sierra Nevada Mountains, like you see here,
22
60000
3000
我的家鄉在内華達州山區西部，大家可以看到，
01:18
in the Red Rock Canyon.
23
63000
2000
就在紅岩峽谷。
01:20
And from these early experiences as a child
24
65000
2000
由於小時候的成長經歷
01:22
I learned to love landscapes.
25
67000
2000
讓我愛上了自然景觀。
01:24
And so when it became time for me to do my graduate studies,
26
69000
2000
因此，當我在念研究所時，
01:26
I studied this emerging field of landscape ecology.
27
71000
4000
我選擇了當時新興的景觀生態學作為我的研究方向。
01:30
Landscape ecology concerns itself
28
75000
2000
景觀生態學主要是在研究
01:32
with how the stream and the meadow and the forest and the cliffs
29
77000
4000
溪流、草地、森林和懸崖
01:36
make habitats for plants and animals.
30
81000
2000
如何構成適合動植物生存的環境。
01:38
This experience and this training
31
83000
2000
這段研究過程
01:40
lead me to get a wonderful job with the Wildlife Conservation Society,
32
85000
3000
讓我在國際野生生物保護協會找到了一份很棒的工作，
01:43
which works to save wildlife and wild places all over the world.
33
88000
3000
主要致力於保護世界各地的野生生物和自然環境。
01:46
And over the last decade,
34
91000
2000
在過去的十年内，
01:48
I traveled to over 40 countries
35
93000
2000
我到過40多個國家，
01:50
to see jaguars and bears and elephants
36
95000
2000
去觀察美洲豹、熊、大象、
01:52
and tigers and rhinos.
37
97000
2000
老虎和犀牛。
01:54
But every time I would return from my trips I'd return back to New York City.
38
99000
3000
每次旅行結束後，我就會回到紐約，
01:57
And on my weekends I would go up, just like all the other tourists,
39
102000
3000
在周末時，我就會跟大多數的遊客一樣，
02:00
to the top of the Empire State Building,
40
105000
2000
登上帝國大廈頂樓，
02:02
and I'd look down on this landscape, on these ecosystems,
41
107000
3000
俯看這片土地，和其生態系統，
02:05
and I'd wonder, "How does this landscape
42
110000
2000
然後我就會想：“這片土地
02:07
work to make habitat for plants and animals?
43
112000
2000
是如何為動植物提供合適的居住地？
02:09
How does it work to make habitat for animals like me?"
44
114000
4000
如何為人們提供合適的居住地？”
02:13
I'd go to Times Square and I'd look at the amazing ladies on the wall,
45
118000
4000
我也會去時代廣場，而當我看着廣告牆上的美女時，
02:17
and wonder why nobody is looking at the historical figures just behind them.
46
122000
5000
我會想，為何没有人看看她們身後的歷史人物呢。
02:22
I'd go to Central Park and see the rolling topography of Central Park
47
127000
3000
我還會去中央公園，
02:25
come up against the abrupt and sheer
48
130000
2000
看著那裡起伏的地形
02:27
topography of midtown Manhattan.
49
132000
4000
和曼哈頓中城高聳的地形形成了鮮明對比。
02:31
I started reading about the history and the geography in New York City.
50
136000
3000
於是我開始研讀紐約市的歷史和地理。
02:34
I read that New York City was the first mega-city,
51
139000
2000
我發現紐約市是世界上第一座超级大城，
02:36
a city of 10 million people or more, in 1950.
52
141000
4000
在1950年居住人口就破千萬。
02:40
I started seeing paintings like this.
53
145000
2000
我開始研究這樣的畫作。
02:42
For those of you who are from New York,
54
147000
2000
在坐來自紐約的聽眾，我要告訴你們，
02:44
this is 125th street under the West Side Highway.
55
149000
3000
這裡是西城高速公路下的125街。
02:47
(Laughter)
56
152000
2000
(笑聲)
02:49
It was once a beach. And this painting
57
154000
2000
這裡曾是一片海灘。
02:51
has John James Audubon, the painter, sitting on the rock.
58
156000
3000
而圖中有一位名叫John James Audubon的畫家，坐在礁石上。
02:54
And it's looking up on the wooded heights of Washington Heights
59
159000
2000
圖中上方長滿樹木的高地是華盛頓高地。
02:56
to Jeffrey's Hook, where the George Washington Bridge goes across today.
60
161000
4000
Jeffrey’s Hook燈塔的方向，即是今天喬治華盛頓大橋横跨之處。
03:00
Or this painting, from the 1740s, from Greenwich Village.
61
165000
3000
或是這幅1740年描繪格林威治村的畫作。
03:03
Those are two students at King's College -- later Columbia University --
62
168000
3000
圖中有兩位國王學院（即現今的哥倫比亞大學）的學生
03:06
sitting on a hill, overlooking a valley.
63
171000
3000
坐在山丘上俯瞰山谷。
03:09
And so I'd go down to Greenwich Village and I'd look for this hill,
64
174000
3000
但是當我到格林威治村去找這座山丘時。
03:12
and I couldn't find it. And I couldn't find that palm tree.
65
177000
3000
卻早就找不到了。就連那棵棕櫚樹也找不到。
03:15
What's that palm tree doing there?
66
180000
2000
不過那裡怎麼會有一棵棕櫚樹？
03:17
(Laughter)
67
182000
1000
(笑聲)
03:18
So, it was in the course of these investigations that I ran into a map.
68
183000
3000
但就在尋訪過程中，我發現到一張地圖，
03:21
And it's this map you see here.
69
186000
2000
就是螢幕上大家看到的這張圖。
03:23
It's held in a geographic information system
70
188000
2000
它存在於地理資訊系统中，
03:25
which allows me to zoom in.
71
190000
2000
因此我就可以進行缩放。
03:27
This map isn't from Hudson's time, but from the American Revolution,
72
192000
3000
這張地圖並非繪製於哈德遜時期，而是在170年後美國獨立革命時，
03:30
170 years later, made by British military cartographers
73
195000
4000
由英國軍事製圖師所繪製，
03:34
during the occupation of New York City.
74
199000
2000
當時英軍占領了紐約市。
03:36
And it's a remarkable map. It's in the National Archives here in Kew.
75
201000
4000
這是一張令人讚嘆的地圖，現存於英國Kew的國家檔案館中。
03:40
And it's 10 feet long and three and a half feet wide.
76
205000
2000
整張地圖長10英尺，寬3.5英尺。
03:42
And if I zoom in to lower Manhattan
77
207000
3000
如果我把曼哈頓下城放大，
03:45
you can see the extent of New York City as it was,
78
210000
2000
大家就可以看到美國獨立革命末期
03:47
right at the end of the American Revolution.
79
212000
2000
紐約市的範圍。
03:49
Here's Bowling Green. And here's Broadway.
80
214000
3000
這裡是Bowling Green，而這裡是百老匯。
03:52
And this is City Hall Park.
81
217000
2000
這邊則是市府公園。
03:54
So the city basically extended to City Hall Park.
82
219000
3000
所以，當時的城市就只有到市府公園。
03:57
And just beyond it you can see features
83
222000
2000
再往上看，
03:59
that have vanished, things that have disappeared.
84
224000
2000
景觀就消失了。
04:01
This is the Collect Pond, which was the fresh water source for New York City
85
226000
3000
這裡是Collect 水塘，它是紐約市
04:04
for its first 200 years,
86
229000
2000
最初200年的飲用水源，
04:06
and for the Native Americans for thousands of years before that.
87
231000
3000
在此之前它滋養了美國原住民數千年。
04:09
You can see the Lispenard Meadows
88
234000
2000
你們可以看到Lispenard草地，
04:11
draining down through here, through what is TriBeCa now,
89
236000
2000
它流過此處，即Tribeca的現址，
04:13
and the beaches that come up from the Battery,
90
238000
2000
而當時的海灘則從Battery
04:15
all the way to 42nd St.
91
240000
2000
一路延伸到42街。
04:17
This map was made for military reasons.
92
242000
3000
這張地圖是為了軍事用途而繪製的。
04:20
They're mapping the roads, the buildings, these fortifications
93
245000
2000
所以他們繪製了道路、建築物以及
04:22
that they built.
94
247000
2000
他們建造的防禦工事。
04:24
But they're also mapping things of ecological interest,
95
249000
2000
除此之外，他們還繪製了具有生態價值的事物，
04:26
also military interest: the hills,
96
251000
2000
當然也具有軍事價值，像是山丘、
04:28
the marshes, the streams.
97
253000
3000
沼澤和溪流。
04:31
This is Richmond Hill, and Minetta Water,
98
256000
2000
這裡則是Richmond山丘和Minetta Water
04:33
which used to run its way through Greenwich Village.
99
258000
3000
它曾經穿過格林威治村。
04:36
Or the swamp at Gramercy Park, right here.
100
261000
5000
Gramercy公園的沼澤在這。
04:41
Or Murray Hill. And this is the Murrays' house
101
266000
2000
這是Murray高地。這則是200年前位於Murray高地上的
04:43
on Murray Hill, 200 years ago.
102
268000
3000
Murray’s House。
04:46
Here is Times Square,
103
271000
3000
這邊是時代廣場，
04:49
the two streams that came together to make a wetland
104
274000
2000
兩條河川交會在此形成一片濕地
04:51
in Times Square, as it was at the end of the American Revolution.
105
276000
5000
也就是在時代廣場的位置，當時是美國獨立戰爭末期。
04:56
So I saw this remarkable map in a book.
106
281000
2000
我是在一本書上看到這張了不起的地圖。
04:58
And I thought to myself, "You know, if I could georeference this map,
107
283000
4000
當時我想：“如果我可以對這張地圖作地理坐標參照，
05:02
if I could place this map in the grid of the city today,
108
287000
3000
如果我可以把這張地圖放在今日紐約市地圖的格線上，
05:05
I could find these lost features
109
290000
2000
那我就能找到
05:07
of the city,
110
292000
2000
這座城市曾有的景觀，
05:09
in the block-by-block geography that people know,
111
294000
3000
一塊塊拼湊出大家熟悉的地貌，
05:12
the geography of where people go to work, and where they go to live,
112
297000
3000
像是我們上班的地點、居住的地方，
05:15
and where they like to eat."
113
300000
2000
以及常去的餐廳。”
05:17
So, after some work we were able to georeference it,
114
302000
2000
在經過一番努力之後，我們完成了地理座標參照，
05:19
which allows us to put the modern streets on the city,
115
304000
3000
我們就可以把現今城市的街道、
05:22
and the buildings, and the open spaces,
116
307000
5000
建築物和開放空間放上去，
05:27
so that we can zoom in to where the Collect Pond is.
117
312000
5000
然後我們就能放大Collect 池塘的所在地，
05:32
We can digitize the Collect Pond and the streams,
118
317000
4000
我們可以將Collect 池塘和溪流數位化，
05:36
and see where they actually are in the geography of the city today.
119
321000
5000
以看出這些地點在現今城市中的實際位置。
05:41
So this is fun for finding where things are
120
326000
3000
有趣的地方在於
05:44
relative to the old topography.
121
329000
5000
找出和原先地形相對應的位置。
05:49
But I had another idea about this map.
122
334000
2000
關於這張地圖我有另一個想法。
05:51
If we take away the streets, and if we take away the buildings,
123
336000
3000
假如我們移除街道、建築，
05:54
and if we take away the open spaces,
124
339000
2000
和開放空間，
05:56
then we could take this map.
125
341000
2000
我們就可以重複使用這張地圖。
05:58
If we pull off the 18th century features
126
343000
2000
如果我們移除18世紀的景觀，
06:00
we could drive it back in time.
127
345000
2000
我們便能穿越時空，
06:02
We could drive it back to its ecological fundamentals:
128
347000
4000
讓它回到最初的基本生態，
06:06
to the hills, to the streams,
129
351000
2000
例如山丘、溪流、
06:08
to the basic hydrology and shoreline, to the beaches,
130
353000
4000
基礎水文、海岸線、海灘等，
06:12
the basic aspects that make the ecological landscape.
131
357000
4000
也就是構成生態地景的基本要素。
06:16
Then, if we added maps like the geology, the bedrock geology,
132
361000
3000
然後，假若我們再加上像地質地圖、床岩地質地圖、
06:19
and the surface geology, what the glaciers leave,
133
364000
3000
地表地質、冰川遺跡，
06:22
if we make the soil map,
134
367000
2000
或是土壤地圖，
06:24
with the 17 soil classes,
135
369000
3000
含有17種
06:27
that are defined by the National Conservation Service,
136
372000
3000
經由國家土壤保育署所界定的土壤類型，
06:30
if we make a digital elevation model
137
375000
2000
如果我們用數值高程模型，
06:32
of the topography that tells us how high the hills were,
138
377000
3000
描繪出代表山丘高度的地形，
06:35
then we can calculate the slopes.
139
380000
3000
我們便能計算出坡度，
06:38
We can calculate the aspect.
140
383000
3000
並算出方位，
06:41
We can calculate the winter wind exposure --
141
386000
2000
還能算出冬季風向，
06:43
so, which way the winter winds blow across the landscape.
142
388000
2000
算出吹過地景的冬季季風走向。
06:45
The white areas on this map are the places protected from the winter winds.
143
390000
5000
地圖上白色的部份是冬季季風吹不到的地方。
06:50
We compiled all the information about where the Native Americans were, the Lenape.
144
395000
3000
我們編輯所有關於當時美國原住民，Lenape部落居住地的資訊
06:53
And we built a probability map about where they might have been.
145
398000
4000
並且繪製他們可能駐足處的機率地圖
06:57
So, the red areas on this map indicate the places
146
402000
2000
紅色區塊是全曼哈頓裡
06:59
that are best for human sustainability on Manhattan,
147
404000
2000
最適合人類居住的地區，
07:01
places that are close to water,
148
406000
2000
因為最靠近河流，
07:03
places that are near the harbor to fish,
149
408000
2000
和可捕魚的港口，
07:05
places protected from the winter winds.
150
410000
5000
也可抵擋冬季刺骨寒風的侵襲。
07:10
We know that there was a Lenape settlement
151
415000
2000
我們都知道Lenape聚落曾居住之處，
07:12
down here by the Collect Pond.
152
417000
3000
就在Collect 池塘旁。
07:15
And we knew that they planted a kind of horticulture,
153
420000
2000
我們也得知他們在那種植花草樹木，
07:17
that they grew these beautiful gardens of corn, beans, and squash,
154
422000
3000
他們一手打造了美麗且生氣蓬勃的穀物、豆類、及南瓜花園，
07:20
the "Three Sisters" garden.
155
425000
2000
也就是“三姐妹”花園。
07:22
So, we built a model that explains where those fields might have been.
156
427000
4000
所以，我們製作了這個模型，來解釋這些花園的可能位置。
07:26
And the old fields, the successional fields that go.
157
431000
2000
以及舊時園地，和後來新園地的位置
07:28
And we might think of these as abandoned.
158
433000
2000
我們也許會以為它們早已荒蕪
07:30
But, in fact, they're grassland habitats
159
435000
2000
但事實上，
07:32
for grassland birds and plants.
160
437000
2000
它們已變成草原鳥類和植物的棲息地。
07:34
And they have become successional shrub lands,
161
439000
3000
並進而演變為灌木林地，
07:37
and these then mix in to a map of all the ecological communities.
162
442000
4000
所有的一切都集合於生態社區地圖中。
07:41
And it turns out that Manhattan had 55 different ecosystem types.
163
446000
4000
所以有55種不同生態系統共同存在於曼哈頓。
07:45
You can think of these as neighborhoods,
164
450000
2000
你可以把他們看成是各有特色的鄰近社區，
07:47
as distinctive as TriBeCa and the Upper East Side and Inwood --
165
452000
5000
就像是Tribeca, Upper East Side和Inwood一樣 --
07:52
that these are the forest and the wetlands
166
457000
2000
只是它們是森林、溼地、
07:54
and the marine communities, the beaches.
167
459000
3000
海洋生態社區，以及沙灘。
07:57
And 55 is a lot. On a per-area basis,
168
462000
3000
55種生態系統算是非常的多。以單位面積來看，
08:00
Manhattan had more ecological communities
169
465000
2000
曼哈頓每英畝擁有比
08:02
per acre than Yosemite does,
170
467000
2000
優勝美地國家公園、
08:04
than Yellowstone, than Amboseli.
171
469000
3000
黃石國家公園，安波沙里國家公園更多的生態社區。
08:07
It was really an extraordinary landscape
172
472000
2000
這真的是非常不可思議的環境
08:09
that was capable of supporting an extraordinary biodiversity.
173
474000
4000
可以讓如此多種的生態社區同時共存。
08:13
So, Act II: A Home Reconstructed.
174
478000
4000
第二部份：重現家園。
08:17
So, we studied the fish and the frogs and the birds and the bees,
175
482000
4000
所以我們開始研究所有曾出現在曼哈頓的生物，像是魚、蛙、鳥、蜜蜂
08:21
the 85 different kinds of fish that were on Manhattan,
176
486000
3000
光是在曼哈頓就曾有85種不同種類的魚，
08:24
the Heath hens, the species that aren't there anymore,
177
489000
4000
新英格蘭黑琴雞(the Heath hens), 現在早已絕種，
08:28
the beavers on all the streams, the black bears,
178
493000
3000
還有曾經在溪流四處可見的河狸和黑熊，
08:31
and the Native Americans, to study how they used
179
496000
3000
和美國原住民，
08:34
and thought about their landscape.
180
499000
2000
要研究他們如何善用和看待這片土地。
08:36
We wanted to try and map these. And to do that what we did
181
501000
3000
我們所需作的就是
08:39
was we mapped their habitat needs.
182
504000
2000
繪製他們的棲息地點分布圖。
08:41
Where do they get their food?
183
506000
2000
例如，他們去哪覓食?
08:43
Where do they get their water? Where do they get their shelter?
184
508000
2000
他們去哪擷取水源? 他們都居住在哪?
08:45
Where do they get their reproductive resources?
185
510000
3000
以及他們去哪取得繁殖資源?
08:48
To an ecologist, the intersection of these is habitat,
186
513000
3000
對生態學家來說，這一切的交集就是所謂的棲息處。
08:51
but to most people, the intersection of these is their home.
187
516000
5000
但對大多數人來說，這則是他們稱為家的地方。
08:56
So, we would read in field guides, the standard field guides
188
521000
2000
所以我們閱讀田野指南，
08:58
that maybe you have on your shelves,
189
523000
2000
我想你們書架上應該都會有這一類的書，
09:00
you know, what beavers need is "A slowly meandering stream
190
525000
2000
例如河狸的棲息處是"蜿蜒而平靜的小溪，
09:02
with aspen trees and alders and willows,
191
527000
3000
兩側有白楊木，赤楊和柳樹，
09:05
near the water." That's the best thing for a beaver.
192
530000
2000
靠近水源處。"這就是海狸的理想家園。
09:07
So we just started making a list.
193
532000
2000
所以我們製作了一張對照表
09:09
Here is the beaver. And here is the stream,
194
534000
2000
左邊是海狸，上面則是牠們的棲息地點：溪流，
09:11
and the aspen and the alder and the willow.
195
536000
2000
白楊木，赤楊和柳樹。
09:13
As if these were the maps that we would need
196
538000
2000
彷彿這些是可以用來預測
09:15
to predict where you would find the beaver.
197
540000
2000
能在哪遇見海狸的地圖。
09:17
Or the bog turtle, needing wet meadows and insects and sunny places.
198
542000
4000
同理，牟式龜需要的是潮濕的草地，昆蟲和陽光充足的地方。
09:21
Or the bobcat, needing rabbits and beavers and den sites.
199
546000
4000
山貓需要兔子，海狸還有洞穴。
09:25
And rapidly we started to realize that beavers can be
200
550000
3000
由此可知，海狸是
09:28
something that a bobcat needs.
201
553000
3000
山貓的獵物。
09:31
But a beaver also needs things. And that having it
202
556000
2000
但海狸也有所需的食物。
09:33
on either side means that we can link it together,
203
558000
2000
把兩邊連結起來之後，
09:35
that we can create the network
204
560000
2000
我們就可以創造出一個
09:37
of the habitat relationships for these species.
205
562000
3000
這些物種的棲息地關係網。
09:40
Moreover, we realized that you can start out
206
565000
2000
再來，我們了解你可以成為
09:42
as being a beaver specialist,
207
567000
2000
一名海狸專家，
09:44
but you can look up what an aspen needs.
208
569000
2000
不過你還可以研究白楊需要什麼。
09:46
An aspen needs fire and dry soils.
209
571000
3000
白楊需要火和乾燥土壤。
09:49
And you can look at what a wet meadow needs.
210
574000
3000
同樣的，你也可以查查潮濕草地需要些什麼。
09:52
And it need beavers to create the wetlands,
211
577000
2000
它需要海狸來製造溼地，
09:54
and maybe some other things.
212
579000
2000
也許你還能探討其他東西。
09:56
But you can also talk about sunny places.
213
581000
2000
但當提到陽光充足的地點時，
09:58
So, what does a sunny place need? Not habitat per se.
214
583000
3000
你會問說，"那它需要什麼呢?" 不是棲息地本身。
10:01
But what are the conditions that make it possible?
215
586000
2000
而是什麼樣的條件讓它充滿陽光
10:03
Or fire. Or dry soils.
216
588000
3000
是火嗎? 還是乾燥土壤?
10:06
And that you can put these on a grid that's 1,000 columns long
217
591000
3000
然後你將所有的資料逐一放在
10:09
across the top and 1,000 rows down the other way.
218
594000
3000
欄列各1000行的表格上後。
10:12
And then we can visualize this data like a network,
219
597000
3000
我們就能把這個生態網路具體化，
10:15
like a social network.
220
600000
2000
就像社群網路一樣。
10:17
And this is the network of all the habitat relationships
221
602000
2000
而這就是所有在曼哈頓的動植物
10:19
of all the plants and animals on Manhattan,
222
604000
2000
及其所需一切的
10:21
and everything they needed,
223
606000
2000
棲地網路圖，
10:23
going back to the geology,
224
608000
2000
我們就能回溯到當時地質的情況，
10:25
going back to time and space at the very core of the web.
225
610000
3000
和網路核心當時的時空。
10:28
We call this the Muir Web. And if you zoom in on it it looks like this.
226
613000
3000
我們稱它為Muir Web。如果你放大來看的話就會像這樣。
10:31
Each point is a different species
227
616000
2000
每一點都代表不同的物種，
10:33
or a different stream or a different soil type.
228
618000
3000
支流，或是土壤種類。
10:36
And those little gray lines are the connections that connect them together.
229
621000
3000
圖中的灰色細線則將它們全部串連起來。
10:39
They are the connections that actually make nature resilient.
230
624000
3000
因為這些連結而讓大自然變得更有適應力。
10:42
And the structure of this is what makes nature work,
231
627000
4000
而其結構正是使自然運作的力量，
10:46
seen with all its parts.
232
631000
2000
由此便可一目了然。
10:48
We call these Muir Webs after the Scottish-American naturalist
233
633000
3000
命名Muir Webs是為紀念蘇格蘭裔美國自然學家John Muir
10:51
John Muir, who said, "When we try to pick out anything by itself,
234
636000
3000
他曾說過，"當我們試著辨識某些事物時，
10:54
we find that it's bound fast by a thousand invisible cords
235
639000
3000
便會發現在其背後，有數以千計無形
10:57
that cannot be broken, to everything in the universe."
236
642000
4000
且密不可分的線索牽動著它，且和宇宙的一切連結。"
11:01
So then we took the Muir webs and we took them back to the maps.
237
646000
3000
所以我們將Muir webs運用到地圖上。
11:04
So if we wanted to go between 85th and 86th,
238
649000
2000
假設我們到了第85和86街，
11:06
and Lex and Third,
239
651000
2000
以及Lexinton大道和第三大道之間，
11:08
maybe there was a stream in that block.
240
653000
2000
或許在這裡曾經有條溪流穿過。
11:10
And these would be the kind of trees that might have been there,
241
655000
2000
也許這種樹曾經在此成長茁壯。
11:12
and the flowers and the lichens and the mosses,
242
657000
4000
還有這些花，地衣，苔蘚，
11:16
the butterflies, the fish in the stream,
243
661000
3000
蝴蝶，溪流裡悠游的魚兒，
11:19
the birds in the trees.
244
664000
2000
以及樹上的鳥兒。
11:21
Maybe a timber rattlesnake lived there.
245
666000
2000
這種山林響尾蛇也可能曾經在此棲息。
11:23
And perhaps a black bear walked by. And maybe Native Americans were there.
246
668000
3000
美洲黑熊也許經過此處。美國原住民也可能落腳於此。
11:26
And then we took this data.
247
671000
2000
而我們將這些資料運用於此。
11:28
You can see this for yourself on our website.
248
673000
2000
你可以在我們的網站上看到這些資料。
11:30
You can zoom into any block on Manhattan,
249
675000
2000
你可以點選曼哈頓任一角落，
11:32
and see what might have been there 400 years ago.
250
677000
3000
就可以看到400年前該地區的生態分布。
11:35
And we used it to try and reveal a landscape
251
680000
3000
我們藉此嘗試將當時的地景呈現出來
11:38
here in Act III.
252
683000
2000
這是第三部分。
11:40
We used the tools they use in Hollywood
253
685000
2000
我們利用好萊塢的特效
11:42
to make these fantastic landscapes that we all see in the movies.
254
687000
3000
製作出如同電影中令人讚嘆的美景。
11:45
And we tried to use it to visualize Third Avenue.
255
690000
3000
我們試著運用3D技術將第三大道具體化。
11:48
So we would take the landscape and we would build up the topography.
256
693000
4000
我們先取得地景，然後建立地形。
11:52
We'd lay on top of that the soils and the waters, and illuminate the landscape.
257
697000
4000
再把土壤和水域分布圖放上去，並調亮地景。
11:56
We would lay on top of that the map of the ecological communities.
258
701000
3000
下一步就是放上生態社區分布圖。
11:59
And feed into that the map of the species.
259
704000
3000
並將生物種類一一加入。
12:02
So that we would actually take a photograph,
260
707000
2000
因此我們到實地拍攝影像，
12:04
flying above Times Square, looking toward the Hudson River,
261
709000
2000
飛越時代廣場上空，遠眺哈德遜河，
12:06
waiting for Hudson to come.
262
711000
2000
等待哈德遜的到來。
12:08
Using this technology, we can make these
263
713000
2000
藉由這項科技，我們可以製作出
12:10
fantastic georeferenced views.
264
715000
2000
絕佳的地理座標參照景觀。
12:12
We can basically take a picture out of any window
265
717000
2000
基本上，我們可以將曼哈頓任一窗外的景色
12:14
on Manhattan and see what that landscape looked like 400 years ago.
266
719000
3000
轉換成400年前的樣貌。
12:17
This is the view from the East River, looking up Murray Hill
267
722000
3000
從東河往Murray高地望去，
12:20
at where the United Nations is today.
268
725000
3000
可以看到聯合國的現址。
12:23
This is the view looking down the Hudson River,
269
728000
2000
這是從哈德遜河上游俯瞰的景色，
12:25
with Manhattan on the left, and New Jersey out on the right,
270
730000
3000
我們可以看到左邊是曼哈頓，紐澤西在右邊，
12:28
looking out toward the Atlantic Ocean.
271
733000
3000
遠方則是大西洋。
12:31
This is the view over Times Square,
272
736000
2000
而這是從時代廣場上空鳥瞰的景觀，
12:33
with the beaver pond there, looking out toward the east.
273
738000
4000
往東邊看過去，河狸水塘就在那邊。
12:37
So we can see the Collect Pond, and Lispenard Marshes back behind.
274
742000
4000
我們也能看到Collect 池塘，Lispenard 沼澤就在後方。
12:41
We can see the fields that the Native Americans made.
275
746000
3000
和美國原住民開拓的園地。
12:44
And we can see this in the geography of the city today.
276
749000
4000
我們能由今日紐約市的地理位置圖看見這個城市的前身。
12:48
So when you're watching "Law and Order," and the lawyers walk up the steps
277
753000
3000
當你在看"法律與秩序(影集)"中的律師們走上階梯時，
12:51
they could have walked back down those steps
278
756000
2000
其實他們正從紐約法院往下走
12:53
of the New York Court House, right into the Collect Pond,
279
758000
2000
一路走往Collect 池塘，
12:55
400 years ago.
280
760000
4000
我是說假如是在400年前。
12:59
So these images are the work of my friend and colleague,
281
764000
3000
這些影像是我的好友兼同事，
13:02
Mark Boyer, who is here in the audience today.
282
767000
2000
Mark Boyer的傑作，他今天也在現場。
13:04
And I'd just like, if you would give him a hand,
283
769000
2000
我想請大家給他鼓掌，
13:06
to call out for his fine work.
284
771000
3000
向他的傑出表現致意。
13:09
(Applause)
285
774000
9000
(掌聲)
13:18
There is such power in bringing science and visualization together,
286
783000
3000
因為科學和視覺化效果的結合，
13:21
that we can create images like this,
287
786000
2000
我們才能創造出像這樣的圖像。
13:23
perhaps looking on either side of a looking glass.
288
788000
3000
就像照鏡子時所看到相反的影像。
13:26
And even though I've only had a brief time to speak,
289
791000
2000
雖然演講時間有限，
13:28
I hope you appreciate that Mannahatta was a very special place.
290
793000
3000
但我還是希望大家都能了解Mannahatta是個非常奇妙的地方。
13:31
The place that you see here on the left side
291
796000
3000
你們所看到圖中的左邊
13:34
was interconnected. It was based on this diversity.
292
799000
2000
因為它的生態多元性，所以和右邊息息相關。
13:36
It had this resilience that is what we need in our modern world.
293
801000
5000
而其中所蘊含的活力正是現今世界所需。
13:41
But I wouldn't have you think that I don't like the place
294
806000
3000
但我不希望你們以為我討厭大城市，
13:44
on the right, which I quite do. I've come to love the city
295
809000
3000
事實上剛好相反。我愛紐約市的多元化
13:47
and its kind of diversity, and its resilience,
296
812000
2000
及活力，
13:49
and its dependence on density and how we're connected together.
297
814000
5000
還有高密度的人口和人與人之間緊密的連結。
13:54
In fact, that I see them as reflections of each other,
298
819000
4000
我把它們看成是一體兩面。
13:58
much as Lewis Carroll did in "Through the Looking Glass."
299
823000
3000
很像是路易斯‧卡洛爾在"愛麗絲鏡中奇緣"中所描述的
14:01
We can compare these two and hold them in our minds at the same time,
300
826000
4000
我們可以同時將兩者放在心中作比較，
14:05
that they really are the same place,
301
830000
2000
它們其實是同一個地方，
14:07
that there is no way that cities can escape from nature.
302
832000
3000
而城市是無法脫離大自然的。
14:10
And I think this is what we're learning about building cities in the future.
303
835000
4000
這也是未來在建造大都市時必須要知道的。
14:14
So if you'll allow me a brief epilogue, not about the past,
304
839000
3000
所以現在我要簡單做個總結，不是關於過去，
14:17
but about 400 years from now,
305
842000
2000
而是關於往後的400年，
14:19
what we're realizing is that
306
844000
2000
我們都了解
14:21
cities are habitats for people,
307
846000
2000
城市是人們的居住地，
14:23
and need to supply what people need:
308
848000
2000
並供給人們生活所需：
14:25
a sense of home, food, water, shelter,
309
850000
3000
像是家的感覺，食物，水和住所，
14:28
reproductive resources, and a sense of meaning.
310
853000
4000
還有繁殖的資源，以及一種感覺
14:32
This is the particular additional habitat requirement of humanity.
311
857000
3000
這是只有人類居住地才特別增加的需求。
14:35
And so many of the talks here at TED are about meaning,
312
860000
3000
TED絕大多數的演講都是關於"意義"，
14:38
about bringing meaning to our lives
313
863000
2000
關於如何為生命帶來意義，
14:40
in all kinds of different ways, through technology,
314
865000
2000
在各種不同方面，透過科技，
14:42
through art, through science,
315
867000
2000
藝術，科學，
14:44
so much so that I think we focus so much on
316
869000
3000
我想我們多半都把焦點放在
14:47
that side of our lives, that we haven't given enough
317
872000
2000
生命的意義，而忽略了
14:49
attention to the food and the water and the shelter,
318
874000
3000
生活的現實面，像是食物，水還有居住處，
14:52
and what we need to raise the kids.
319
877000
3000
以及扶養小孩所需。
14:55
So, how can we envision the city of the future?
320
880000
3000
所以，我們該如何展望未來的紐約市？
14:58
Well, what if we go to Madison Square Park,
321
883000
2000
假想有天我們到麥迪遜廣場公園，
15:00
and we imagine it without all the cars,
322
885000
3000
而公園裡面完全沒有車子，
15:03
and bicycles instead
323
888000
2000
只有自行車，
15:05
and large forests, and streams instead of sewers and storm drains?
324
890000
5000
廣大的森林和潺潺流水，而非下水道和排水溝？
15:10
What if we imagined the Upper East Side
325
895000
2000
試想如果上東城充滿著
15:12
with green roofs, and streams winding through the city,
326
897000
4000
綠色植物，穿越市中心的溪流
15:16
and windmills supplying the power we need?
327
901000
3000
和供應用電的風車？
15:19
Or if we imagine the New York City metropolitan area,
328
904000
3000
或想像紐約市大都會區
15:22
currently home to 12 million people,
329
907000
2000
這樣擁有1200萬人口的都市，
15:24
but 12 million people in the future, perhaps living at the density of Manhattan,
330
909000
4000
但未來光是曼哈頓區，可能就有1200萬人口
15:28
in only 36 percent of the area,
331
913000
2000
居住在僅占紐約市36%的精華地區，
15:30
with the areas in between covered by farmland,
332
915000
3000
其間遍佈田地，
15:33
covered by wetlands,
333
918000
2000
溼地，
15:35
covered by the marshes we need.
334
920000
2000
還有我們所需的沼澤地。
15:37
This is the kind of future I think we need,
335
922000
3000
這是我們所期望的未來，
15:40
is a future that has the same diversity
336
925000
3000
這樣的未來擁有相同的生物多樣性
15:43
and abundance and dynamism of Manhattan,
337
928000
3000
豐富性及曼哈頓特有的活力，
15:46
but that learns from the sustainability of the past,
338
931000
3000
但同時又能從過去學習永續發展之道，
15:49
of the ecology, the original ecology, of nature with all its parts.
339
934000
5000
無論是在生態，原生態，或是關於自然的一切。
15:54
Thank you very much.
340
939000
2000
非常感謝大家
15:56
(Applause)

941000

ABOUT THE SPEAKER
Eric Sanderson - Landscape ecologistArmed with an 18th-century map, a GPS and reams of data, Eric Sanderson has re-plotted the Manhattan of 1609, just in time for New York's quadricentennial.
Why you should listen
Before becoming the center of the Western cultural universe, Manhattan was Mannahatta, "Island of many hills," in the language of 17th-century Native Americans. Using computer modeling, painstaking research and a lot of legwork, Wildlife Conservation Society ecologist Eric Sanderson has re-envisioned, block by block, the ecology of Manhattan as it was when Henry Hudson first sailed into the forested harbor in 1609.
The Mannahatta Project presents the eye-popping fruits of Sanderson's research, from the now-flattened hills of the financial district to the river otters of Harlem. The project's astonishing visualizations are realized by computer-graphics wizard Markley Boyer, and encompasses a book, a website and a 3-D map -- a sort of Google Earth of ancient New York. Plaques around town will commemorate a lost creek or habitat. Far more than a mournful look back at what has been irrevocably paved over, the Mannahatta Project is designed to inspire ecological sustainability for New York and for other cities.
