ABOUT THE SPEAKER
Danny Dorling - Social geographer
Danny Dorling teaches and writes about the geography of our human world.

Why you should listen

Danny Dorling has invented new map projections and new ways of measuring and describing inequality -- and analyzed thousands of datasets about people and the planet. He is the Halford Mackinder Professor of Geography at the University of Oxford, UK. His work concerns issues of housing, health, employment, education, wealth and poverty.

In the press, Dorling has been described as "that rare university professor: expert, politically engaged and able to explain simply why his subject matters," and as one who has made it "his life's work to dig through the layers that make up Britain's human landscape, and then map it in ways nobody else had thought to do." Working with many others, he has done the same for all the countries of the world "giving a strikingly different perspective from the Mercator projection most commonly used." All this mapping lead him to worry more about inequality.

His recent books include co-authored texts The Atlas of the Real World: Mapping the Way We LiveBankrupt Britain: An atlas of social change, and People and Places a 21st-century Atlas of the UK. Recent sole-authored books include So You Think You Know about Britain and Fair Play, both in 2011; in 2012 The No-nonsense Guide to Equality, The Visualization of Spatial Social Structure and The Population of the UK; Unequal Health: The Scandal of Our Times, The 32 Stops and Population Ten Billion in 2013; All That Is Solid in 2014; Injustice: Why social inequalities persist in 2015; and A Better Politics: How Government Can Make Us Happier in 2016.

I'd like you to imagine the world anew.

00:17
I'd like to show you some maps,
1
5840
2176
00:20
which have been drawn by Ben Hennig,
2
8039
2737
00:22
of the planet in a way
3
10800
1696
00:24
that most of you will never
have seen the planet depicted before.
4
12520
5080
00:30
Here's an image
that you're very familiar with.
5
18480
3080
00:34
I'm old enough that I was actually born
before we saw this image.
6
22480
4056
00:38
Apparently some of my first words
were "moona, moona,"
7
26560
2576
00:41
but I think that's my mom
having a particular fantasy
8
29160
3096
00:44
about what her baby boy could see
9
32280
2256
00:46
on the flickering
black and white TV screen.
10
34560
3280
00:51
It's only been a few centuries
11
39680
1616
00:53
since we've actually, most of us,
thought of our planet as spherical.
12
41320
3240
00:58
When we first saw
these images in the 1960s,
13
46160
3056
01:01
the world was changing
at an incredible rate.
14
49240
3280
01:06
In my own little discipline
of human geography,
15
54320
3320
01:10
a cartographer called Waldo Tobler
16
58600
2736
01:13
was drawing new maps of the planet,
17
61360
2536
01:15
and these maps have now spread,
18
63920
1496
01:17
and I'm going to show you one of them now.
19
65440
2007
01:20
This map is a map of the world,
20
68200
2480
01:23
but it's a map which looks to you
21
71720
2416
01:26
a little bit strange.
22
74160
1440
01:28
It's a map in which we stretched places,
23
76200
3816
01:32
so that those areas which contain
many people are drawn larger,
24
80040
4696
01:36
and those areas,
like the Sahara and the Himalayas,
25
84760
2936
01:39
in which there are few people,
have been shrunk away.
26
87720
2480
01:42
Everybody on the planet
is given an equal amount of space.
27
90760
3640
01:47
The cities are shown shining bright.
28
95120
2840
01:50
The lines are showing you
submarine cables and trade routes.
29
98680
3576
01:54
And there's one particular line
that goes from the Chinese port of Dalian
30
102280
3656
01:57
through past Singapore,
31
105960
1696
01:59
through the Suez Canal,
32
107680
1736
02:01
through the Mediterranean
and round to Rotterdam.
33
109440
2336
02:03
And it's showing you the route
34
111800
1496
02:05
of what was the world's
largest ship just a year ago,
35
113320
3936
02:09
a ship which was taking
so many containers of goods
36
117280
6016
02:15
that when they were unloaded,
37
123320
1856
02:17
if the lorries had all gone in convoy,
they would have been 100 kilometers long.
38
125200
4240
02:22
This is how our world is now connected.
39
130680
2736
02:25
This is the quantity of stuff
we are now moving around the world,
40
133440
5976
02:31
just on one ship, on one voyage,
41
139440
2736
02:34
in five weeks.
42
142200
1200
02:38
We've lived in cities
for a very long time,
43
146320
2520
02:41
but most of us didn't live in cities.
44
149640
2216
02:43
This is Çatalhöyük,
one of the world's first cities.
45
151880
3136
02:47
At its peak 9,000 years ago,
46
155040
3240
02:51
people had to walk over the roofs
of others' houses to get to their home.
47
159160
6200
02:58
If you look carefully
at the map of the city,
48
166080
3296
03:01
you'll see it has no streets,
49
169400
1920
03:04
because streets are something we invented.
50
172280
2680
03:07
The world changes.
51
175760
2216
03:10
It changes by trial and error.
52
178000
1880
03:13
We work out slowly and gradually
53
181400
2896
03:16
how to live in better ways.
54
184320
1800
03:19
And the world has changed
incredibly quickly most recently.
55
187480
5000
03:25
It's only within the last six,
seven, or eight generations
56
193600
3936
03:29
that we have actually realized
that we are a species.
57
197560
3080
03:33
It's only within the last few decades
58
201840
2560
03:37
that a map like this could be drawn.
59
205240
2760
03:42
Again, the underlying map
is the map of world population,
60
210240
4200
03:47
but over it, you're seeing arrows
showing how we spread out of Africa
61
215560
5656
03:53
with dates showing you
where we think we arrived
62
221240
3776
03:57
at particular times.
63
225040
1760
03:59
I have to redraw this map
every few months,
64
227680
3856
04:03
because somebody makes a discovery
that a particular date was wrong.
65
231560
4976
04:08
We are learning about ourselves
at an incredible speed.
66
236560
4520
04:15
And we're changing.
67
243600
1200
04:18
A lot of change is gradual.
68
246640
2256
04:20
It's accretion.
69
248920
1496
04:22
We don't notice the change
70
250440
2856
04:25
because we only have short lives,
71
253320
1816
04:27
70, 80, if you're lucky 90 years.
72
255160
2600
04:30
This graph is showing you
73
258560
2016
04:32
the annual rate of population
growth in the world.
74
260600
2720
04:36
It was very low until around about 1850,
75
264120
3936
04:40
and then the rate of population growth
76
268080
2616
04:42
began to rise
77
270720
1240
04:44
so that around the time I was born,
78
272840
2016
04:46
when we first saw those images
from the moon of our planet,
79
274880
4720
04:52
our global population
was growing at two percent a year.
80
280640
3360
04:57
If it had carried on growing
at two percent a year
81
285440
3960
05:02
for just another couple of centuries,
82
290600
2840
05:06
the entire planet would be covered
83
294560
2256
05:08
with a seething mass of human bodies
84
296840
3056
05:11
all touching each other.
85
299920
2040
05:15
And people were scared.
86
303000
1816
05:16
They were scared of population growth
87
304840
1816
05:18
and what they called
"the population bomb" in 1968.
88
306680
3336
05:22
But then, if you look
at the end of the graph,
89
310040
2200
05:25
the growth began to slow.
90
313240
2600
05:28
The decade --
91
316720
1376
05:30
the '70s, the '80s,
the '90s, the noughties,
92
318120
3456
05:33
and in this decade, even faster --
93
321600
2240
05:36
our population growth is slowing.
94
324600
1616
05:38
Our planet is stabilizing.
95
326240
1256
05:39
We are heading towards nine,
10, or 11 billion people
96
327520
3016
05:42
by the end of the century.
97
330560
1240
05:44
Within that change, you can see tumult.
98
332400
3336
05:47
You can see the Second World War.
99
335760
1816
05:49
You can see the pandemic
in 1918 from influenza.
100
337600
4176
05:53
You can see the great Chinese famine.
101
341800
1880
05:56
These are the events
we tend to concentrate on.
102
344400
2296
05:58
We tend to concentrate
on the terrible events in the news.
103
346720
3936
06:02
We don't tend to concentrate
on the gradual change
104
350680
3656
06:06
and the good news stories.
105
354360
1640
06:09
We worry about people.
106
357480
1696
06:11
We worry about how many people there are.
107
359200
2256
06:13
We worry about how you can
get away from people.
108
361480
3160
06:17
But this is the map of the world
changed again to make area large,
109
365200
3400
06:21
the further away
people are from each area.
110
369760
4376
06:26
So if you want to know
where to go to get away from everybody,
111
374160
3936
06:30
here's the best places to go.
112
378120
2576
06:32
And every year, these areas get bigger,
113
380720
2816
06:35
because every year,
we are coming off the land globally.
114
383560
3256
06:38
We are moving into the cities.
115
386840
1456
06:40
We are packing in more densely.
116
388320
2176
06:42
There are wolves again in Europe,
117
390520
1616
06:44
and the wolves are moving west
across the continent.
118
392160
3920
06:49
Our world is changing.
119
397200
1400
06:52
You have worries.
120
400920
1320
06:55
This is a map showing
where the water falls on our planet.
121
403680
4896
07:00
We now know that.
122
408600
1696
07:02
And you can look at where Çatalhöyük was,
123
410320
3776
07:06
where three continents meet,
Africa, Asia, and Europe,
124
414120
2576
07:08
and you can see there are
a large number of people living there
125
416720
2976
07:11
in areas with very little water.
126
419720
1576
07:13
And you can see areas in which
there is a great deal of rainfall as well.
127
421320
3696
07:17
And we can get a bit more sophisticated.
128
425040
2160
07:20
Instead of making
the map be shaped by people,
129
428440
3376
07:23
we can shape the map by water,
130
431840
2216
07:26
and then we can change it every month
131
434080
1856
07:27
to show the amount of water
132
435960
1656
07:29
falling on every small part of the globe.
133
437640
3200
07:33
And you see the monsoons
moving around the planet,
134
441920
3296
07:37
and the planet almost appears
to have a heartbeat.
135
445240
3600
07:41
And all of this only became possible
136
449720
4520
07:46
within my lifetime
137
454920
1776
07:48
to see this is where we are living.
138
456720
3160
07:52
We have enough water.
139
460640
1200
07:55
This is a map of where
we grow our food in the world.
140
463760
4360
08:01
This is the areas that we will rely on
most for rice and maize and corn.
141
469280
4440
08:07
People worry that there won't
be enough food, but we know,
142
475760
2856
08:10
if we just ate less meat
and fed less of the crops to animals,
143
478640
4776
08:15
there is enough food for everybody
144
483440
2416
08:17
as long as we think of ourselves
as one group of people.
145
485880
4320
08:24
And we also know
146
492120
1280
08:27
about what we do
147
495280
2056
08:29
so terribly badly nowadays.
148
497360
2560
08:33
You will have seen this map
of the world before.
149
501480
4840
08:39
This is the map
150
507480
1936
08:41
produced by taking satellite images,
151
509440
3376
08:44
if you remember those satellites
around the planet
152
512840
2776
08:47
in the very first slide I showed,
153
515640
1760
08:51
and producing an image
of what the Earth looks like at night.
154
519240
3000
08:55
When you normally see that map,
155
523720
1896
08:57
on a normal map, the kind of map
that most of you will be used to,
156
525640
3520
09:02
you think you are seeing
a map of where people live.
157
530160
3280
09:06
Where the lights are shining up
is where people live.
158
534120
2480
09:09
But here, on this image of the world,
159
537320
4376
09:13
remember we've stretched the map again.
160
541720
1880
09:17
Everywhere has the same density
of people on this map.
161
545320
4360
09:22
If an area doesn't have people,
162
550480
2176
09:24
we've shrunk it away
163
552680
1896
09:26
to make it disappear.
164
554600
1536
09:28
So we're showing everybody
165
556160
2136
09:30
with equal prominence.
166
558320
1440
09:33
Now, the lights no longer show you
where people are,
167
561320
3296
09:36
because people are everywhere.
168
564640
1440
09:39
Now the lights on the map,
169
567120
1936
09:41
the lights in London,
the lights in Cairo, the lights in Tokyo,
170
569080
2976
09:44
the lights on the Eastern Seaboard
of the United States,
171
572080
2936
09:47
the lights show you where people live
172
575040
2936
09:50
who are so profligate with energy
173
578000
2200
09:53
that they can afford
174
581160
1520
09:55
to spend money
175
583680
1536
09:57
powering lights to shine up into the sky,
176
585240
3456
10:00
so satellites can draw an image like this.
177
588720
3080
10:04
And the areas that are dark on the map
178
592840
2120
10:07
are either areas where people
do not have access to that much energy,
179
595720
3720
10:12
or areas where people do,
180
600400
2096
10:14
but they have learned to stop
shining the light up into the sky.
181
602520
4840
10:19
And if I could show you this map
animated over time,
182
607960
3536
10:23
you would see that Tokyo
has actually become darker,
183
611520
3576
10:27
because ever since the tsunami in Japan,
184
615120
2800
10:30
Japan has had to rely
on a quarter less electricity
185
618880
2416
10:33
because it turned
the nuclear power stations off.
186
621320
3000
10:37
And the world didn't end.
187
625240
1400
10:39
You just shone less light
188
627400
2176
10:41
up into the sky.
189
629600
1920
10:45
There are a huge number
190
633320
2976
10:48
of good news stories in the world.
191
636320
2440
10:51
Infant mortality is falling
192
639880
3416
10:55
and has been falling
at an incredible rate.
193
643320
3880
10:59
A few years ago,
194
647920
1440
11:02
the number of babies dying
in their first year of life in the world
195
650240
3936
11:06
fell by five percent in just one year.
196
654200
3080
11:11
More children are going to school
197
659600
2496
11:14
and learning to read and write
198
662120
2616
11:16
and getting connected to the Internet
199
664760
2816
11:19
and going on to go to university
200
667600
3016
11:22
than ever before at an incredible rate,
201
670640
3896
11:26
and the highest number of young people
going to university in the world
202
674560
5456
11:32
are women, not men.
203
680040
1880
11:35
I can give you good news story
after good news story
204
683160
3896
11:39
about what is getting
better in the planet,
205
687080
2616
11:41
but we tend to concentrate
206
689720
2560
11:45
on the bad news that is immediate.
207
693880
2736
11:48
Rebecca Solnit, I think,
put it brilliantly,
208
696640
3200
11:53
when she explained: "The accretion
of incremental, imperceptible changes
209
701160
4440
11:58
which can constitute progress
and which render our era
210
706520
2816
12:01
dramatically different from the past" --
211
709360
2816
12:04
the past was much more stable --
212
712200
2040
12:07
"a contrast obscured by the undramatic
nature of gradual transformation,
213
715640
4976
12:12
punctuated by occasional tumult."
214
720640
2960
12:16
Occasionally, terrible things happen.
215
724320
2360
12:19
You are shown those terrible things
216
727440
2736
12:22
on the news every night of the week.
217
730200
3656
12:25
You are not told about
the population slowing down.
218
733880
3976
12:29
You are not told about the world
becoming more connected.
219
737880
3016
12:32
You are not told about the incredible
improvements in understanding.
220
740920
3656
12:36
You are not told about
how we are learning to begin
221
744600
3136
12:39
to waste less and consume less.
222
747760
2456
12:42
This is my last map.
223
750240
1200
12:44
On this map, we have taken the seas
224
752360
2376
12:46
and the oceans out.
225
754760
1800
12:49
Now you are just looking
226
757480
2016
12:51
at about 7.4 billion people
227
759520
3856
12:55
with the map drawn
in proportion to those people.
228
763400
2920
12:59
You're looking at over a billion in China,
229
767240
2056
13:01
and you can see the largest
city in the world in China,
230
769320
2816
13:04
but you do not know its name.
231
772160
1480
13:07
You can see that India
232
775080
1856
13:08
is in the center of this world.
233
776960
2080
13:11
You can see that Europe is on the edge.
234
779640
3296
13:14
And we in Exeter today
235
782960
3056
13:18
are on the far edge of the planet.
236
786040
2936
13:21
We are on a tiny scrap of rock
237
789000
2976
13:24
off Europe
238
792000
1696
13:25
which contains less than one percent
239
793720
2616
13:28
of the world's adults,
240
796360
2016
13:30
and less than half a percent
241
798400
2536
13:32
of the world's children.
242
800960
1840
13:35
We are living in a stabilizing world,
an urbanizing world,
243
803640
4616
13:40
an aging world,
244
808280
1976
13:42
a connecting world.
245
810280
2136
13:44
There are many, many things
to be frightened about,
246
812440
3440
13:48
but there is no need for us
to fear each other as much as we do,
247
816720
5216
13:53
and we need to see
that we are now living in a new world.
248
821960
4240
13:58
Thank you very much.
249
826960

ABOUT THE SPEAKER
Danny Dorling - Social geographer
Danny Dorling teaches and writes about the geography of our human world.

Why you should listen

Danny Dorling has invented new map projections and new ways of measuring and describing inequality -- and analyzed thousands of datasets about people and the planet. He is the Halford Mackinder Professor of Geography at the University of Oxford, UK. His work concerns issues of housing, health, employment, education, wealth and poverty.

In the press, Dorling has been described as "that rare university professor: expert, politically engaged and able to explain simply why his subject matters," and as one who has made it "his life's work to dig through the layers that make up Britain's human landscape, and then map it in ways nobody else had thought to do." Working with many others, he has done the same for all the countries of the world "giving a strikingly different perspective from the Mercator projection most commonly used." All this mapping lead him to worry more about inequality.

His recent books include co-authored texts The Atlas of the Real World: Mapping the Way We LiveBankrupt Britain: An atlas of social change, and People and Places a 21st-century Atlas of the UK. Recent sole-authored books include So You Think You Know about Britain and Fair Play, both in 2011; in 2012 The No-nonsense Guide to Equality, The Visualization of Spatial Social Structure and The Population of the UK; Unequal Health: The Scandal of Our Times, The 32 Stops and Population Ten Billion in 2013; All That Is Solid in 2014; Injustice: Why social inequalities persist in 2015; and A Better Politics: How Government Can Make Us Happier in 2016.
