Jane Goodall hasn't found the missing link, but she's come closer than nearly anyone else. The primatologist says the only real difference between humans and chimps is our sophisticated language. She urges us to start using it to change the world.
Jane Goodall - Primatologist; environmentalist
Jane Goodall, dubbed by her biographer "the woman who redefined man," has changed our perceptions of primates, people, and the connection between the two. Over the past 45 years, Goodall herself has also evolved -- from steadfast scientist to passionate conservationist and humanitarian. Full bio

Good morning everyone. First of all, it's been fantastic
0
1000
4000
00:30
being here over these past few days.
1
5000
3000
00:33
And secondly, I feel it's a great honor to kind of wind up
2
8000
4000
00:37
this extraordinary gathering of people,
3
12000
2000
00:39
these amazing talks that we've had.
4
14000
3000
00:42
I feel that I've fitted in, in many ways,
5
17000
3000
00:45
to some of the things that I've heard.
6
20000
3000
00:48
I came directly here
7
23000
4000
00:52
from the deep, deep tropical rainforest in Ecuador,
8
27000
4000
00:57
where I was out -- you could only get there by a plane --
9
32000
3000
01:00
with indigenous people with paint on their faces
10
35000
3000
01:04
and parrot feathers on their headdresses,
11
39000
2000
01:06
where these people are fighting to try and keep the oil companies,
12
41000
5000
01:11
and keep the roads, out of their forests.
13
46000
4000
01:15
They're fighting to develop their own way of living within the forest
14
50000
4000
01:19
in a world that's clean, a world that isn't contaminated,
15
54000
3000
01:22
a world that isn't polluted.
16
57000
3000
01:25
And what was so amazing to me, and what fits right in
17
60000
3000
01:28
with what we're all talking about here at TED,
18
63000
3000
01:31
is that there, right in the middle of this rainforest,
19
66000
3000
01:34
was some solar panels -- the first in that part of Ecuador --
20
69000
4000
01:39
and that was mainly to bring water up by pump
21
74000
3000
01:42
so that the women wouldn't have to go down.
22
77000
2000
01:44
The water was cleaned, but because they got a lot of batteries,
23
79000
3000
01:47
they were able to store a lot of electricity.
24
82000
3000
01:50
So every house -- and there were, I think, eight houses
25
85000
2000
01:52
in this little community -- could have light
26
87000
3000
01:55
for, I think it was about half an hour each evening.
27
90000
2000
01:58
And there is the Chief, in all his regal finery, with a laptop computer.
28
93000
6000
02:04
(Laughter)
29
99000
2000
02:06
And this man, he has been outside, but he's gone back,
30
101000
5000
02:11
and he was saying, "You know, we have suddenly jumped into
31
106000
6000
02:17
a whole new era, and we didn't even know about the white man
32
112000
4000
02:21
50 years ago, and now here we are with laptop computers,
33
116000
3000
02:24
and there are some things we want to learn from the modern world.
34
119000
3000
02:27
We want to know about health care.
35
122000
3000
02:30
We want to know about what other people do -- we're interested in it.
36
125000
4000
02:34
And we want to learn other languages.
37
129000
2000
02:36
We want to know English and French and perhaps Chinese,
38
131000
4000
02:40
and we're good at languages."
39
135000
2000
02:42
So there he is with his little laptop computer,
40
137000
4000
02:46
but fighting against the might of the pressures --
41
141000
4000
02:50
because of the debt, the foreign debt of Ecuador --
42
145000
3000
02:53
fighting the pressure of World Bank, IMF, and of course
43
148000
4000
02:57
the people who want to exploit the forests and take out the oil.
44
152000
4000
03:02
And so, coming directly from there to here.
45
157000
4000
03:06
But, of course, my real field of expertise
46
161000
3000
03:09
lies in an even different kind of civilization --
47
164000
4000
03:13
I can't really call it a civilization.
48
168000
3000
03:16
A different way of life, a different being.
49
171000
3000
03:20
We've talked earlier -- this wonderful talk by Wade Davis
50
175000
5000
03:25
about the different cultures of the humans around the world --
51
180000
3000
03:28
but the world is not composed only of human beings;
52
183000
5000
03:33
there are also other animal beings.
53
188000
2000
03:35
And I propose to bring into this TED conference,
54
190000
3000
03:38
as I always do around the world, the voice of the animal kingdom.
55
193000
4000
03:42
Too often we just see a few slides, or a bit of film,
56
197000
3000
03:45
but these beings have voices that mean something.
57
200000
3000
03:48
And so, I want to give you a greeting,
58
203000
2000
03:50
as from a chimpanzee in the forests of Tanzania --
59
205000
3000
03:54
Ooh, ooh, ooh, ooh, ooh, ooh, ooh, ooh, ooh, ooh, ooh, ooh, ooh, ooh, ooh!
60
209000
6000
04:01
(Applause)
61
216000
8000
04:10
I've been studying chimpanzees in Tanzania since 1960.
62
225000
5000
04:15
During that time, there have been modern technologies
63
230000
4000
04:19
that have really transformed the way
64
234000
2000
04:21
that field biologists do their work.
65
236000
3000
04:24
For example, for the first time, a few years ago,
66
239000
3000
04:27
by simply collecting little fecal samples
67
242000
3000
04:30
we were able to have them analyzed -- to have DNA profiling done --
68
245000
5000
04:35
so for the first time, we actually know which male chimps
69
250000
4000
04:39
are the fathers of each individual infant.
70
254000
3000
04:42
Because the chimps have a very promiscuous mating society.
71
257000
4000
04:46
So this opens up a whole new avenue of research.
72
261000
3000
04:49
And we use GSI -- geographic whatever it is, GSI --
73
264000
7000
04:56
to determine the range of the chimps.
74
271000
4000
05:00
And we're using -- you can see that I'm not really into this kind of stuff --
75
275000
6000
05:06
but we're using satellite imagery
76
281000
3000
05:09
to look at the deforestation in the area.
77
284000
3000
05:12
And of course, there's developments in infrared,
78
287000
3000
05:15
so you can watch animals at night,
79
290000
2000
05:17
and equipment for recording by video,
80
292000
3000
05:20
and tape recording is getting lighter and better.
81
295000
3000
05:23
So in many, many ways, we can do things today
82
298000
3000
05:26
that we couldn't do when I began in 1960.
83
301000
4000
05:31
Especially when chimpanzees, and other animals
84
306000
3000
05:34
with large brains, are studied in captivity,
85
309000
2000
05:36
modern technology is helping us to search
86
311000
5000
05:41
for the upper levels of cognition in some of these non-human animals.
87
316000
4000
05:45
So that we know today, they're capable of performances
88
320000
4000
05:49
that would have been thought absolutely impossible
89
324000
2000
05:51
by science when I began.
90
326000
2000
05:54
I think the chimpanzee in captivity who is the most skilled
91
329000
4000
05:58
in intellectual performance is one called Ai in Japan --
92
333000
4000
06:02
her name means love --
93
337000
2000
06:04
and she has a wonderfully sensitive partner working with her.
94
339000
4000
06:08
She loves her computer --
95
343000
2000
06:10
she'll leave her big group, and her running water,
96
345000
3000
06:13
and her trees and everything.
97
348000
2000
06:15
And she'll come in to sit at this computer --
98
350000
2000
06:17
it's like a video game for a kid; she's hooked.
99
352000
2000
06:19
She's 28, by the way, and she does things with her computer screen
100
354000
4000
06:23
and a touch pad that she can do faster than most humans.
101
358000
6000
06:29
She does very complex tasks, and I haven't got time to go into them,
102
364000
5000
06:34
but the amazing thing about this female is
103
369000
2000
06:36
she doesn't like making mistakes.
104
371000
4000
06:40
If she has a bad run, and her score isn't good,
105
375000
3000
06:43
she'll come and reach up and tap on the glass --
106
378000
2000
06:45
because she can't see the experimenter --
107
380000
2000
06:47
which is asking to have another go.
108
382000
3000
06:50
And her concentration -- she's already concentrated hard
109
385000
3000
06:53
for 20 minutes or so, and now she wants to do it all over again,
110
388000
4000
06:57
just for the satisfaction of having done it better.
111
392000
3000
07:00
And the food is not important -- she does get a tiny reward,
112
395000
3000
07:03
like one raisin for a correct response --
113
398000
3000
07:06
but she will do it for nothing, if you tell her beforehand.
114
401000
4000
07:10
So here we are, a chimpanzee using a computer.
115
405000
5000
07:15
Chimpanzees, gorillas, orangutans also learn human sign language.
116
410000
4000
07:19
But the point is that when I was first in Gombe in 1960 --
117
414000
5000
07:24
I remember so well, so vividly, as though it was yesterday --
118
419000
4000
07:28
the first time, when I was going through the vegetation,
119
423000
3000
07:31
the chimpanzees were still running away from me, for the most part,
120
426000
3000
07:34
although some were a little bit acclimatized --
121
429000
4000
07:38
and I saw this dark shape, hunched over a termite mound,
122
433000
4000
07:42
and I peered with my binoculars.
123
437000
2000
07:44
It was, fortunately, one adult male whom I'd named David Greybeard --
124
439000
5000
07:49
and by the way, science at that time was telling me that I shouldn't name the chimps;
125
444000
3000
07:52
they should all have numbers; that was more scientific.
126
447000
2000
07:54
Anyway, David Greybeard -- and I saw that
127
449000
3000
07:57
he was picking little pieces of grass and using them
128
452000
4000
08:01
to fish termites from their underground nest.
129
456000
3000
08:04
And not only that -- he would sometimes pick a leafy twig
130
459000
3000
08:07
and strip the leaves --
131
462000
2000
08:09
modifying an object to make it suitable for a specific purpose --
132
464000
3000
08:12
the beginning of tool-making.
133
467000
2000
08:15
The reason this was so exciting and such a breakthrough
134
470000
2000
08:17
is at that time, it was thought that humans,
135
472000
3000
08:20
and only humans, used and made tools.
136
475000
3000
08:23
When I was at school, we were defined as man, the toolmaker.
137
478000
4000
08:27
So that when Louis Leakey, my mentor, heard this news,
138
482000
4000
08:31
he said, "Ah, we must now redefine 'man,' redefine 'tool,'
139
486000
3000
08:34
or accept chimpanzees as humans."
140
489000
3000
08:37
(Laughter)
141
492000
2000
08:39
We now know that at Gombe alone, there are nine different ways
142
494000
4000
08:43
in which chimpanzees use different objects for different purposes.
143
498000
3000
08:47
Moreover, we know that in different parts of Africa,
144
502000
2000
08:49
wherever chimps have been studied,
145
504000
2000
08:51
there are completely different tool-using behaviors.
146
506000
5000
08:56
And because it seems that these patterns are passed
147
511000
3000
08:59
from one generation to the next, through observation,
148
514000
3000
09:02
imitation and practice -- that is a definition of human culture.
149
517000
5000
09:07
What we find is that over these 40-odd years
150
522000
4000
09:11
that I and others have been studying chimpanzees
151
526000
3000
09:14
and the other great apes, and, as I say, other mammals
152
529000
3000
09:17
with complex brains and social systems,
153
532000
3000
09:20
we have found that after all, there isn't a sharp line
154
535000
4000
09:24
dividing humans from the rest of the animal kingdom.
155
539000
3000
09:27
It's a very wuzzy line.
156
542000
2000
09:29
It's getting wuzzier all the time as we find animals doing things
157
544000
3000
09:32
that we, in our arrogance, used to think was just human.
158
547000
5000
09:37
The chimps -- there's no time to discuss their fascinating lives --
159
552000
4000
09:41
but they have this long childhood, five years
160
556000
3000
09:44
of suckling and sleeping with the mother,
161
559000
2000
09:46
and then another three, four or five years
162
561000
2000
09:48
of emotional dependence on her, even when the next child is born.
163
563000
5000
09:53
The importance of learning in that time, when behavior is flexible --
164
568000
3000
09:56
and there's an awful lot to learn in chimpanzee society.
165
571000
4000
10:00
The long-term affectionate supportive bonds
166
575000
3000
10:03
that develop throughout this long childhood with the mother,
167
578000
3000
10:06
with the brothers and sisters,
168
581000
2000
10:08
and which can last through a lifetime,
169
583000
3000
10:11
which may be up to 60 years.
170
586000
2000
10:13
They can actually live longer than 60 in captivity,
171
588000
3000
10:16
so we've only done 40 years in the wild so far.
172
591000
3000
10:19
And we find chimps are capable of true compassion and altruism.
173
594000
5000
10:25
We find in their non-verbal communication -- this is very rich --
174
600000
4000
10:29
they have a lot of sounds, which they use in different circumstances,
175
604000
5000
10:34
but they also use touch, posture, gesture,
176
609000
2000
10:36
and what do they do?
177
611000
2000
10:38
They kiss; they embrace; they hold hands.
178
613000
2000
10:40
They pat one another on the back; they swagger; they shake their fist --
179
615000
3000
10:43
the kind of things that we do,
180
618000
3000
10:46
and they do them in the same kind of context.
181
621000
2000
10:49
They have very sophisticated cooperation.
182
624000
2000
10:51
Sometimes they hunt -- not that often,
183
626000
3000
10:54
but when they hunt, they show sophisticated cooperation,
184
629000
3000
10:57
and they share the prey.
185
632000
2000
11:00
We find that they show emotions, similar to -- maybe sometimes the same --
186
635000
6000
11:06
as those that we describe in ourselves as happiness, sadness, fear, despair.
187
641000
5000
11:11
They know mental as well as physical suffering.
188
646000
2000
11:13
And I don't have time to go into the information
189
648000
3000
11:16
that will prove some of these things to you,
190
651000
2000
11:18
save to say that there are very bright students, in the best universities,
191
653000
4000
11:22
studying emotions in animals, studying personalities in animals.
192
657000
4000
11:26
We know that chimpanzees and some other creatures
193
661000
3000
11:29
can recognize themselves in mirrors -- "self" as opposed to "other."
194
664000
5000
11:34
They have a sense of humor, and these are the kind of things
195
669000
4000
11:38
which traditionally have been thought of as human prerogatives.
196
673000
6000
11:44
But this teaches us a new respect -- and it's a new respect
197
679000
5000
11:49
not only for the chimpanzees, I suggest,
198
684000
3000
11:52
but some of the other amazing animals with whom we share this planet.
199
687000
4000
11:56
Once we're prepared to admit that after all,
200
691000
3000
11:59
we're not the only beings with personalities, minds
201
694000
3000
12:02
and above all feelings, and then we start to think
202
697000
2000
12:04
about ways we use and abuse
203
699000
2000
12:06
so many other sentient, sapient creatures on this planet,
204
701000
6000
12:12
it really gives cause for deep shame, at least for me.
205
707000
5000
12:19
So, the sad thing is that these chimpanzees --
206
714000
4000
12:23
who've perhaps taught us, more than any other creature, a little humility --
207
718000
4000
12:27
are in the wild, disappearing very fast.
208
722000
3000
12:30
They're disappearing for the reasons
209
725000
2000
12:32
that all of you in this room know only too well.
210
727000
3000
12:35
The deforestation, the growth of human populations, needing more land.
211
730000
5000
12:40
They're disappearing because some timber companies
212
735000
3000
12:43
go in with clear-cutting.
213
738000
2000
12:45
They're disappearing in the heart of their range in Africa
214
740000
4000
12:49
because the big multinational logging companies have come in and made roads --
215
744000
5000
12:54
as they want to do in Ecuador
216
749000
2000
12:56
and other parts where the forests remain untouched --
217
751000
2000
12:59
to take out oil or timber.
218
754000
4000
13:03
And this has led in Congo basin, and other parts of the world,
219
758000
5000
13:08
to what is known as the bush-meat trade.
220
763000
2000
13:10
This means that although for hundreds, perhaps thousands of years,
221
765000
4000
13:14
people have lived in those forests, or whatever habitat it is,
222
769000
4000
13:18
in harmony with their world, just killing the animals they need
223
773000
3000
13:21
for themselves and their families --
224
776000
2000
13:23
now, suddenly, because of the roads,
225
778000
3000
13:26
the hunters can go in from the towns.
226
781000
2000
13:28
They shoot everything, every single thing that moves
227
783000
3000
13:31
that's bigger than a small rat; they sun-dry it or smoke it.
228
786000
5000
13:36
And now they've got transport; they take it on the logging trucks
229
791000
3000
13:39
or the mining trucks into the towns where they sell it.
230
794000
4000
13:43
And people will pay more for bush-meat, as it's called,
231
798000
5000
13:48
than for domestic meat -- it's culturally preferred.
232
803000
3000
13:51
And it's not sustainable, and the huge logging camps in the forest
233
806000
4000
13:55
are now demanding meat, so the Pygmy hunters in the Congo basin
234
810000
4000
13:59
who've lived there with their wonderful way of living
235
814000
4000
14:03
for so many hundreds of years are now corrupted.
236
818000
3000
14:06
They're given weapons; they shoot for the logging camps; they get money.
237
821000
3000
14:09
Their culture is being destroyed,
238
824000
3000
14:12
along with the animals upon whom they depend.
239
827000
3000
14:15
So, when the logging camp moves, there's nothing left.
240
830000
3000
14:18
We talked already about the loss of human cultural diversity,
241
833000
3000
14:21
and I've seen it happening with my own eyes.
242
836000
3000
14:24
And the grim picture in Africa -- I love Africa,
243
839000
4000
14:28
and what do we see in Africa?
244
843000
2000
14:30
We see deforestation;
245
845000
3000
14:33
we see the desert spreading; we see massive hunger;
246
848000
5000
14:38
we see disease and we see population growth in areas
247
853000
4000
14:42
where there are more people living on a certain piece of land
248
857000
4000
14:46
than the land can possibly support,
249
861000
2000
14:48
and they're too poor to buy food from elsewhere.
250
863000
3000
14:51
Were the people that we heard about yesterday,
251
866000
3000
14:54
on the Easter Island, who cut down their last tree -- were they stupid?
252
869000
4000
14:58
Didn't they know what was happening?
253
873000
2000
15:00
Of course, but if you've seen the crippling poverty
254
875000
2000
15:02
in some of these parts of the world
255
877000
2000
15:04
it isn't a question of "Let's leave the tree for tomorrow."
256
879000
3000
15:07
"How am I going to feed my family today?
257
882000
2000
15:09
Maybe I can get just a few dollars from this last tree
258
884000
3000
15:12
which will keep us going a little bit longer,
259
887000
2000
15:14
and then we'll pray that something will happen
260
889000
3000
15:17
to save us from the inevitable end."
261
892000
3000
15:20
So, this is a pretty grim picture.
262
895000
3000
15:23
The one thing we have, which makes us so different
263
898000
4000
15:27
from chimpanzees or other living creatures,
264
902000
2000
15:29
is this sophisticated spoken language --
265
904000
3000
15:32
a language with which we can tell children
266
907000
2000
15:34
about things that aren't here.
267
909000
2000
15:36
We can talk about the distant past, plan for the distant future,
268
911000
4000
15:40
discuss ideas with each other,
269
915000
2000
15:42
so that the ideas can grow from the accumulated wisdom of a group.
270
917000
4000
15:46
We can do it by talking to each other;
271
921000
2000
15:48
we can do it through video; we can do it through the written word.
272
923000
4000
15:52
And we are abusing this great power we have to be wise stewards,
273
927000
5000
15:57
and we're destroying the world.
274
932000
2000
15:59
In the developed world, in a way, it's worse,
275
934000
3000
16:02
because we have so much access to knowledge
276
937000
3000
16:05
of the stupidity of what we're doing.
277
940000
2000
16:07
Do you know, we're bringing little babies
278
942000
3000
16:10
into a world where, in many places, the water is poisoning them?
279
945000
5000
16:15
And the air is harming them, and the food that's grown
280
950000
4000
16:19
from the contaminated land is poisoning them.
281
954000
3000
16:22
And that's not just in the far-away developing world; that's everywhere.
282
957000
4000
16:26
Do you know we all have about 50 chemicals
283
961000
2000
16:28
in our bodies we didn't have about 50 years ago?
284
963000
4000
16:32
And so many of these diseases, like asthma
285
967000
4000
16:36
and certain kinds of cancers, are on the increase
286
971000
3000
16:39
around places where our filthy toxic waste is dumped.
287
974000
5000
16:44
We're harming ourselves around the world,
288
979000
3000
16:47
as well as harming the animals, as well as harming nature herself --
289
982000
4000
16:51
Mother Nature, that brought us into being;
290
986000
3000
16:54
Mother Nature, where I believe we need to spend time,
291
989000
4000
16:58
where there's trees and flowers and birds
292
993000
2000
17:00
for our good psychological development.
293
995000
3000
17:03
And yet, there are hundreds and hundreds of children
294
998000
3000
17:06
in the developed world who never see nature,
295
1001000
2000
17:08
because they're growing up in concrete
296
1003000
2000
17:10
and all they know is virtual reality,
297
1005000
2000
17:12
with no opportunity to go and lie in the sun,
298
1007000
4000
17:16
or in the forest, with the dappled sun-specks
299
1011000
3000
17:19
coming down from the canopy above.
300
1014000
3000
17:22
As I was traveling around the world, you know,
301
1017000
3000
17:25
I had to leave the forest -- that's where I love to be.
302
1020000
3000
17:28
I had to leave these fascinating chimpanzees
303
1023000
3000
17:31
for my students and field staff to continue studying
304
1026000
4000
17:35
because, finding they dwindled from about two million
305
1030000
3000
17:38
100 years ago to about 150,000 now,
306
1033000
4000
17:42
I knew I had to leave the forest to do what I could
307
1037000
3000
17:45
to raise awareness around the world.
308
1040000
2000
17:47
And the more I talked about the chimpanzees' plight,
309
1042000
3000
17:50
the more I realized the fact that everything's interconnected,
310
1045000
5000
17:55
and the problems of the developing world
311
1050000
2000
17:57
so often stem from the greed of the developed world,
312
1052000
3000
18:00
and everything was joining together, and making -- not sense,
313
1055000
5000
18:05
hope lies in sense, you said -- it's making a nonsense.
314
1060000
4000
18:09
How can we do it?
315
1064000
1000
18:10
Somebody said that yesterday.
316
1065000
2000
18:12
And as I was traveling around, I kept meeting young people who'd lost hope.
317
1067000
5000
18:17
They were feeling despair,
318
1072000
3000
18:20
they were feeling, "Well, it doesn't matter what we do;
319
1075000
3000
18:23
eat, drink and be merry, for tomorrow we die.
320
1078000
2000
18:25
Everything is hopeless -- we're always being told so by the media."
321
1080000
4000
18:29
And then I met some who were angry,
322
1084000
3000
18:32
and anger that can turn to violence,
323
1087000
2000
18:34
and we're all familiar with that.
324
1089000
3000
18:37
And I have three little grandchildren,
325
1092000
4000
18:41
and when some of these students would say to me
326
1096000
3000
18:44
at high school or university, they'd say, "We're angry,"
327
1099000
3000
18:47
or "We're filled with despair, because we feel
328
1102000
3000
18:50
you've compromised our future, and there's nothing we can do about it."
329
1105000
4000
18:54
And I looked in the eyes of my little grandchildren,
330
1109000
2000
18:56
and think how much we've harmed this planet since I was their age.
331
1111000
4000
19:00
I feel this deep shame, and that's why in 1991 in Tanzania,
332
1115000
6000
19:06
I started a program that's called Roots and Shoots.
333
1121000
3000
19:09
There's little brochures all around outside,
334
1124000
4000
19:13
and if any of you have anything to do with children and care about their future,
335
1128000
4000
19:17
I beg that you pick up that brochure.
336
1132000
3000
19:20
And Roots and Shoots is a program for hope.
337
1135000
4000
19:24
Roots make a firm foundation.
338
1139000
2000
19:26
Shoots seem tiny,
339
1141000
2000
19:28
but to reach the sun they can break through brick walls.
340
1143000
3000
19:31
See the brick walls as all the problems
341
1146000
2000
19:33
that we've inflicted on this planet.
342
1148000
2000
19:35
Then, you see, it is a message of hope.
343
1150000
4000
19:39
Hundreds and thousands of young people around the world
344
1154000
2000
19:41
can break through, and can make this a better world.
345
1156000
4000
19:45
And the most important message of Roots and Shoots
346
1160000
3000
19:48
is that every single individual makes a difference.
347
1163000
4000
19:52
Every individual has a role to play.
348
1167000
2000
19:54
Every one of us impacts the world around us everyday,
349
1169000
4000
19:58
and you scientists know that you can't actually --
350
1173000
3000
20:01
even if you stay in bed all day, you're breathing oxygen
351
1176000
3000
20:04
and giving out CO2, and probably going to the loo,
352
1179000
4000
20:08
and things like that --
353
1183000
2000
20:10
you're making a difference in the world.
354
1185000
2000
20:12
So, the Roots and Shoots program
355
1187000
3000
20:15
involves youth in three kinds of projects.
356
1190000
5000
20:20
And these are projects to make the world around them a better place.
357
1195000
4000
20:24
One project to show care and concern for your own human community.
358
1199000
6000
20:30
One for animals, including domestic animals -- and I have to say,
359
1205000
4000
20:34
I learned everything I know about animal behavior
360
1209000
2000
20:36
even before I got to Gombe and the chimps from my dog, Rusty,
361
1211000
4000
20:40
who was my childhood companion.
362
1215000
3000
20:43
And the third kind of project: something for the local environment.
363
1218000
4000
20:48
So what the kids do depends first of all, how old are they --
364
1223000
4000
20:52
and we go now from pre-school right through university.
365
1227000
4000
20:56
It's going to depend whether they're inner-city or rural.
366
1231000
3000
20:59
It's going to depend if they're wealthy or impoverished.
367
1234000
5000
21:04
It's going to depend which part, say, of America they're in.
368
1239000
3000
21:07
We're in every state now, and the problems in Florida
369
1242000
3000
21:10
are different from the problems in New York.
370
1245000
2000
21:13
It's going to depend on which country they're in --
371
1248000
2000
21:15
and we're already in 60-plus countries, with about 5,000 active groups --
372
1250000
6000
21:21
and there are groups all over the place that I keep hearing about
373
1256000
4000
21:25
that I've never even heard of, because the kids are taking the program
374
1260000
3000
21:28
and spreading it themselves.
375
1263000
2000
21:30
Why?
376
1265000
2000
21:32
Because they're buying into it,
377
1267000
2000
21:34
and they're the ones who get to decide what they're going to do.
378
1269000
3000
21:37
It isn't something that their parents tell them,
379
1272000
2000
21:39
or their teachers tell them.
380
1274000
2000
21:41
That's effective, but if they decide themselves,
381
1276000
3000
21:44
"We want to clean this river
382
1279000
3000
21:47
and put the fish back that used to be there.
383
1282000
2000
21:49
We want to clear away the toxic soil
384
1284000
5000
21:54
from this area and have an organic garden.
385
1289000
2000
21:56
We want to go and spend time with the old people
386
1291000
3000
21:59
and hear their stories and record their oral histories.
387
1294000
4000
22:04
We want to go and work in a dog shelter.
388
1299000
2000
22:06
We want to learn about animals. We want ... "
389
1301000
2000
22:08
You know, it goes on and on, and this is very hopeful for me.
390
1303000
4000
22:12
As I travel around the world 300 days a year,
391
1307000
4000
22:16
everywhere there's a group of Roots and Shoots of different ages.
392
1311000
3000
22:19
Everywhere there are children with shining eyes saying,
393
1314000
2000
22:21
"Look at the difference we've made."
394
1316000
3000
22:24
And now comes the technology into it,
395
1319000
2000
22:26
because with this new way of communicating electronically
396
1321000
5000
22:31
these kids can communicate with each other around the world.
397
1326000
4000
22:35
And if anyone is interested to help us, we've got so many ideas
398
1330000
3000
22:38
but we need help -- we need help to create the right kind of system
399
1333000
6000
22:44
that will help these young people to communicate their excitement.
400
1339000
4000
22:48
But also -- and this is so important -- to communicate their despair,
401
1343000
5000
22:53
to say, "We've tried this and it doesn't work, and what shall we do?"
402
1348000
3000
22:56
And then, lo and behold, there's another group answering these kids
403
1351000
4000
23:00
who may be in America, or maybe this is a group in Israel,
404
1355000
3000
23:03
saying, "Yeah, you did it a little bit wrong. This is how you should do it."
405
1358000
5000
23:08
The philosophy is very simple.
406
1363000
3000
23:11
We do not believe in violence.
407
1366000
3000
23:14
No violence, no bombs, no guns.
408
1369000
3000
23:17
That's not the way to solve problems.
409
1372000
2000
23:19
Violence leads to violence, at least in my view.
410
1374000
4000
23:23
So how do we solve?
411
1378000
2000
23:25
The tools for solving the problems are knowledge and understanding.
412
1380000
5000
23:30
Know the facts, but see how they fit in the big picture.
413
1385000
3000
23:33
Hard work and persistence --don't give up --
414
1388000
3000
23:36
and love and compassion leading to respect for all life.
415
1391000
5000
23:41
How many more minutes? Two, one?
416
1396000
2000
23:43
Chris Anderson: One -- one to two.
417
1398000
2000
23:45
Jane Goodall: Two, two, I'm going to take two.
418
1400000
2000
23:47
(Laughter)
419
1402000
1000
23:48
Are you going to come and drag me off?
420
1403000
2000
23:50
(Laughter)
421
1405000
2000
23:52
Anyway -- so basically, Roots and Shoots
422
1407000
4000
23:56
is beginning to change young people's lives.
423
1411000
3000
23:59
It's what I'm devoting most of my energy to.
424
1414000
4000
24:03
And I believe that a group like this can have a very major impact,
425
1418000
7000
24:10
not just because you can share technology with us,
426
1425000
3000
24:13
but because so many of you have children.
427
1428000
3000
24:16
And if you take this program out, and give it to your children,
428
1431000
5000
24:21
they have such a good opportunity to go out and do good,
429
1436000
4000
24:25
because they've got parents like you.
430
1440000
2000
24:27
And it's been so clear how much you all care
431
1442000
4000
24:31
about trying to make this world a better place.
432
1446000
2000
24:33
It's very encouraging.
433
1448000
2000
24:35
But the kids do ask me --
434
1450000
2000
24:37
and this won't take more than two minutes, I promise --
435
1452000
2000
24:39
the kids say, "Dr. Jane, do you really have hope for the future?
436
1454000
5000
24:44
You travel, you see all these horrible things happening."
437
1459000
4000
24:48
Firstly, the human brain -- I don't need to say anything about that.
438
1463000
4000
24:52
Now that we know what the problems are around the world,
439
1467000
3000
24:55
human brains like yours are rising to solve those problems.
440
1470000
4000
24:59
And we've talked a lot about that.
441
1474000
2000
25:01
Secondly, the resilience of nature.
442
1476000
3000
25:04
We can destroy a river,
443
1479000
2000
25:06
and we can bring it back to life.
444
1481000
2000
25:08
We can see a whole area desolated,
445
1483000
5000
25:13
and it can be brought back to bloom again, with time or a little help.
446
1488000
5000
25:18
And thirdly, the last speaker talked about -- or the speaker before last,
447
1493000
6000
25:24
talked about the indomitable human spirit.
448
1499000
3000
25:27
We are surrounded by the most amazing people
449
1502000
4000
25:31
who do things that seem to be absolutely impossible.
450
1506000
4000
25:35
Nelson Mandela -- I take a little piece of limestone
451
1510000
3000
25:38
from Robben Island Prison, where he labored for 27 years,
452
1513000
3000
25:41
and came out with so little bitterness, he could lead his people
453
1516000
5000
25:46
from the horror of apartheid without a bloodbath.
454
1521000
3000
25:49
Even after the 11th of September -- and I was in New York
455
1524000
4000
25:53
and I felt the fear -- nevertheless, there was so much human courage,
456
1528000
6000
25:59
so much love and so much compassion.
457
1534000
3000
26:02
And then as I went around the country after that and felt the fear --
458
1537000
4000
26:06
the fear that was leading to people feeling
459
1541000
2000
26:08
they couldn't worry about the environment any more,
460
1543000
2000
26:10
in case they seemed not to be patriotic --
461
1545000
3000
26:13
and I was trying to encourage them,
462
1548000
2000
26:15
somebody came up with a little quotation from Mahatma Gandhi,
463
1550000
3000
26:18
"If you look back through human history,
464
1553000
3000
26:21
you see that every evil regime has been overcome by good."
465
1556000
3000
26:25
And just after that a woman brought me this little bell,
466
1560000
4000
26:29
and I want to end on this note.
467
1564000
2000
26:31
She said, "If you're talking about hope and peace, ring this.
468
1566000
3000
26:36
This bell is made from metal from a defused landmine,
469
1571000
6000
26:42
from the killing fields of Pol Pot --
470
1577000
3000
26:45
one of the most evil regimes in human history --
471
1580000
3000
26:48
where people are now beginning to put their lives back together
472
1583000
4000
26:52
after the regime has crumbled.
473
1587000
3000
26:55
So, yes, there is hope, and where is the hope?
474
1590000
4000
26:59
Is it out there with the politicians?
475
1594000
3000
27:03
It's in our hands.
476
1598000
2000
27:05
It's in your hands and my hands
477
1600000
2000
27:07
and those of our children.
478
1602000
2000
27:09
It's really up to us.
479
1604000
2000
27:11
We're the ones who can make a difference.
480
1606000
2000
27:13
If we lead lives where we consciously leave
481
1608000
2000
27:15
the lightest possible ecological footprints,
482
1610000
4000
27:19
if we buy the things that are ethical for us to buy
483
1614000
3000
27:22
and don't buy the things that are not,
484
1617000
3000
27:25
we can change the world overnight.
485
1620000
3000
27:28
Thank you.

ABOUT THE SPEAKER
Jane Goodall - Primatologist; environmentalistJane Goodall, dubbed by her biographer "the woman who redefined man," has changed our perceptions of primates, people, and the connection between the two. Over the past 45 years, Goodall herself has also evolved -- from steadfast scientist to passionate conservationist and humanitarian.
Why you should listen
Jane Goodall hasn't exactly found the missing link, but she's come closer than just about anyone else on Earth. Her extensive research into the behavior of chimpanzees, which started in Africa in the 1960s and continues today, fundamentally altered scientific thinking about the relationship between humans and other mammals.
Goodall, who founded a research institute in her name in 1977, is an internationally recognized authority on the primate world. She's written books for adults and children, contributed to documentaries, and serves as a National Geographic explorer-in-residence, a United Nations peace messenger, and the president of Advocates for Animals. For her efforts to observe and preserve all species, Goodall has received honors and accolades from governments, nonprofits, universities, and professional organizations, including a medal from UNESCO and the French Legion of Honor in 2006.
