Seven Worlds, One Planet - First Season English Subtitles

1
00:00:22,023 --> 00:00:23,983
200 million years ago,

2
00:00:24,108 --> 00:00:27,570
our planet looked very different
from what it does today.

3
00:00:27,695 --> 00:00:30,114
It was entirely covered by sea,

4
00:00:30,239 --> 00:00:35,286
which surrounded one single
supercontinent we call Pangaea.

5
00:00:37,038 --> 00:00:40,124
And then Pangaea began to break up.

6
00:00:42,251 --> 00:00:46,964
Life was cast adrift on fragments of land.

7
00:00:49,050 --> 00:00:53,971
And these fragments eventually
became our seven continents.

8
00:00:56,182 --> 00:00:59,977
We will see how life developed
on each continent,

9
00:01:00,102 --> 00:01:05,775
giving rise to the extraordinary
and wonderful diversity that we see today.

1
00:00:37,038 --> 00:00:41,959
Asia - the largest
of all the Earth's continents.

2
00:00:45,254 --> 00:00:50,676
It stretches from the equator
to beyond the Arctic Circle.

3
00:00:53,137 --> 00:00:56,807
This is a continent of extremes.

4
00:01:01,395 --> 00:01:07,401
Here, temperatures can drop
to below minus 60 degrees Celsius.

5
00:01:09,528 --> 00:01:12,782
On land, survival is almost impossible.

6
00:01:15,534 --> 00:01:18,329
But for a few weeks in summer,

7
00:01:18,454 --> 00:01:22,875
the ice melts
and the coast is transformed.

8
00:01:33,678 --> 00:01:37,515
This is one of the biggest gatherings
of mammals

9
00:01:37,640 --> 00:01:41,143
to be found anywhere on Earth.

1
00:00:37,830 --> 00:00:40,583
At the southern tip of South America,

2
00:00:40,708 --> 00:00:44,295
the Andes mountains rise
almost vertically.

3
00:00:50,468 --> 00:00:55,514
Their very height affects
life throughout the continent.

4
00:00:59,268 --> 00:01:03,064
The barren slopes look inhospitable.

5
00:01:09,654 --> 00:01:14,700
But like all parts of South America,
they're actually rich with wildlife.

6
00:01:25,753 --> 00:01:28,089
A family of puma.

7
00:01:35,513 --> 00:01:40,268
They live further south
than any other kind of cat on Earth.

8
00:01:50,569 --> 00:01:53,281
These cubs are only six months old -

9
00:01:53,406 --> 00:01:56,784
entirely dependent on their mother
for food.

1
00:00:40,917 --> 00:00:42,627
Australia -

2
00:00:42,752 --> 00:00:44,545
an island continent

3
00:00:44,670 --> 00:00:49,425
cast adrift
during the time of the dinosaurs.

4
00:01:09,570 --> 00:01:15,243
Isolated from the rest of life on land
for millions of years,

5
00:01:15,368 --> 00:01:21,499
the animals cast away here
are today like none elsewhere.

6
00:01:24,919 --> 00:01:28,547
This is a land of survivors.

7
00:01:57,201 --> 00:02:02,623
The jungles of northern Australia -
the oldest on our planet.

8
00:02:05,293 --> 00:02:09,672
Unchanged for 180 million years.

9
00:02:13,050 --> 00:02:16,846
The animals and plants here are armed...

1
00:00:35,912 --> 00:00:38,372
Europe.

2
00:00:38,497 --> 00:00:43,252
Home to 850 million people.

3
00:00:48,382 --> 00:00:53,804
This is a continent
that has been transformed by humanity.

4
00:00:58,559 --> 00:01:00,645
It is a crowded world.

5
00:01:07,902 --> 00:01:10,488
But not all of it.

6
00:01:12,281 --> 00:01:17,453
There are still precious areas
of wilderness

7
00:01:17,578 --> 00:01:22,166
and, living within them,
some very surprising animals.

8
00:01:42,520 --> 00:01:46,274
Forest once covered 80% of Europe.

9
00:01:50,361 --> 00:01:53,823
Now only half of it remains.

10

1
00:00:44,462 --> 00:00:47,506
One continent on our planet changes

2
00:00:47,632 --> 00:00:49,550
more dramatically than any other.

3
00:00:58,893 --> 00:00:59,852
North America.

4
00:00:59,977 --> 00:01:05,316
Whole landscapes here can be transformed
in a matter of minutes.

5
00:01:23,417 --> 00:01:28,089
And all life has to be ready
to seize the moment.

6
00:01:28,214 --> 00:01:31,175
Getting it wrong can be disastrous.

7
00:01:32,885 --> 00:01:37,056
But time it correctly,
and there can be great rewards.

8
00:01:42,770 --> 00:01:44,855
This is a land of opportunity.

9
00:01:51,696 --> 00:01:54,949
Over 100 times the size of Great Britain,

10

1
00:00:50,176 --> 00:00:51,677
Africa.

2
00:00:54,472 --> 00:01:00,228
No continent on Earth today
has such spectacular wildlife.

3
00:01:04,232 --> 00:01:09,153
At its heart lies
a vast tropical rainforest.

4
00:01:13,866 --> 00:01:17,453
Over a million square miles
of wilderness,

5
00:01:17,578 --> 00:01:21,207
much of it still unexplored...

6
00:01:21,332 --> 00:01:22,708
...even now.

7
00:01:28,631 --> 00:01:32,551
There are more species of animals
and plants in these jungles

8
00:01:32,677 --> 00:01:34,679
than anywhere else on the continent.

9
00:01:40,893 --> 00:01:43,396
But even in this land of plenty...
