A NETFLIX DOCUMENTARY SERIES

2
00:00:14,200 --> 00:00:17,600
<i>Every year</i>
<i>for just a few months,</i>

3
00:00:19,240 --> 00:00:23,160
<i>fresh water flows into the Okavango Delta…</i>

4
00:00:27,680 --> 00:00:29,280
<i>creating the perfect home…</i>

5
00:00:31,320 --> 00:00:33,560
<i>to a small family of elephants.</i>

6
00:00:38,000 --> 00:00:41,840
<i>And a playground</i>
<i>for her two new puppies.</i>

7
00:00:44,520 --> 00:00:45,600
<i>Bosigo…</i>

8
00:00:47,680 --> 00:00:49,160
<i>and his cousin,</i>

9
00:00:50,200 --> 00:00:51,040
<i>Metsi.</i>

10
00:00:59,440 --> 00:01:05,480
<i>Bosigo and Metsi are just getting started</i>
<i>your love affair with water.</i>

11
00:01:09,000 --> 00:01:10,320
<i>From now on,</i>

12
00:01:11,200 --> 00:01:13,800
<i>their lives will be defined by it.</i>

13
00:01:15,960 --> 00:01:19,040
<i>This precious molecule…</i>

14
00:01:21,400 --> 00:01:22,720
<i>delivered to Earth…</i>

15
00:01:25,400 --> 00:01:29,680
<i>by surprising forces</i>
<i>in action in our Universe.</i>

16
00:01:36,200 --> 00:01:38,520
<i>She transformed this planet…</i>

17
00:01:41,760 --> 00:01:43,200
<i>in an oasis…</i>

18
00:01:48,600 --> 00:01:49,560
<i>for life.</i>

19
00:02:11,640 --> 00:02:18,640
A WORLD OF WATER

20
00:02:22,080 --> 00:02:26,120
OKAVANGO DELTA, BOTSWANA

21
00:02:26,200 --> 00:02:27,720
<i>Summer has arrived.</i>

22
00:02:30,360 --> 00:02:32,080
<i>And what was paradise</i>

23
00:02:33,040 --> 00:02:34,200
<i>not anymore.</i>

24
00:02:37,360 --> 00:02:39,840
<i>The fresh water that flooded the delta…</i>

25
00:02:42,800 --> 00:02:45,360
<i>only lasts a few months</i>

26
00:02:46,720 --> 00:02:48,800
<i>and the ponds are disappearing.</i>

27
00:02:50,520 --> 00:02:51,360
<i>Quickly.</i>

28
00:02:58,520 --> 00:03:00,320
<i>This only means one thing</i>

29
00:03:00,400 --> 00:03:03,640
<i>to the thousands</i>
<i>of elephants that live here:</i>

30
00:03:06,240 --> 00:03:08,080
<i>it's time to move on.</i>

31
00:03:21,960 --> 00:03:26,480
<i>This is the only house</i>
<i>that Metsi and Bosigo know.</i>

32
00:03:28,720 --> 00:03:32,160
<i>But in a few weeks,</i>
<i>all the water will disappear.</i>

33
00:03:36,160 --> 00:03:40,000
<i>So they need to leave</i>
<i>the delta with the rest of the family.</i>

34
00:03:41,160 --> 00:03:43,120
<i>A herd of females,</i>

35
00:03:43,200 --> 00:03:46,360
<i>sisters, aunts and cousins.</i>

36
00:03:48,080 --> 00:03:49,680
<i>Led by grandmother,</i>

37
00:03:50,760 --> 00:03:53,640
<i>the great matriarch, Pula.</i>

38
00:03:58,360 --> 00:04:02,440
<i>They will embark on a journey</i>
<i>with thousands of other families.</i>

39
00:04:05,160 --> 00:04:06,560
<i>Passing through the desert.</i>

40
00:04:10,280 --> 00:04:11,600
<i>In search of water.</i>

41
00:04:18,840 --> 00:04:20,480
<i>In the next eight months,</i>

42
00:04:20,560 --> 00:04:24,840
<i>they will migrate from pond to pond…</i>

43
00:04:27,320 --> 00:04:30,160
<i>and they will walk</i>
<i>through ancient elephant trails</i>

44
00:04:31,200 --> 00:04:34,040
<i>using the knowledge of the Pula matriarch,</i>

45
00:04:35,320 --> 00:04:37,640
<i>passed down to her through generations.</i>

46
00:04:40,480 --> 00:04:43,080
<i>The walk will put</i>
<i>all lives at risk.</i>

47
00:04:45,080 --> 00:04:51,040
<i>And they will need all of yours</i>
<i>senses to face dangers.</i>

48
00:04:55,640 --> 00:04:58,920
<i>Taking this trip is not a choice.</i>

49
00:05:04,640 --> 00:05:07,200
<i>Without water, they will die.</i>

50
00:05:11,320 --> 00:05:13,880
<i>Even on our blue planet,</i>

51
00:05:13,960 --> 00:05:16,960
<i>fresh water is scarce.</i>

52
00:05:20,160 --> 00:05:23,480
<i>And if we look</i>
<i>beyond the shores of our planet…</i>

53
00:05:25,480 --> 00:05:27,000
<i>it is even rarer.</i>

54
00:05:30,320 --> 00:05:32,880
<i>Even the driest desert on Earth</i>

55
00:05:33,640 --> 00:05:38,080
<i>it's nothing compared</i>
<i>to the rest of our solar system.</i>

56
00:05:41,560 --> 00:05:44,080
<i>In the cold of outer space...</i>

57
00:05:48,760 --> 00:05:50,280
SATURN

58
00:05:50,360 --> 00:05:52,720
<i>…the only water on the surface is ice.</i>

59
00:05:56,880 --> 00:05:59,320
<i>Like the frozen moons of Saturn...</i>

60
00:06:01,640 --> 00:06:07,400
<i>where ice fountains gush</i>
<i>for kilometers in space.</i>

61
00:06:14,520 --> 00:06:17,800
<i>Closest to the Sun, on Mars,</i>

62
00:06:18,720 --> 00:06:22,280
<i>water is eliminated</i>
<i>by wild solar winds.</i>

63
00:06:32,640 --> 00:06:34,240
<i>And on Venus,</i>

64
00:06:34,320 --> 00:06:36,040
<i>it just boils.</i>

65
00:06:45,560 --> 00:06:48,320
<i>There is only one world we know</i>

66
00:06:48,400 --> 00:06:51,800
<i>who has the present</i>
<i>having liquid water on its surface.</i>

67
00:06:57,120 --> 00:06:59,160
<i>A light blue dot.</i>

68
00:07:00,920 --> 00:07:02,000
<i>Our home.</i>

69
00:07:08,160 --> 00:07:10,080
<i>Where, at this moment,</i>

70
00:07:10,880 --> 00:07:16,840
<i>the water is carrying a family</i>
<i>on a survival mission.</i>

71
00:07:24,600 --> 00:07:26,840
<i>Only a month after leaving the delta,</i>

72
00:07:27,920 --> 00:07:30,800
<i>only a few muddy puddles remain…</i>

73
00:07:34,840 --> 00:07:40,120
<i>that get smaller and smaller</i>
<i>and more spread every day.</i>

74
00:07:43,840 --> 00:07:46,200
<i>Pula is using your memory</i>
<i>highly tuned</i>

75
00:07:46,280 --> 00:07:48,560
<i>to take your family to a pond.</i>

76
00:07:55,040 --> 00:07:57,240
<i>She can remember the exact route</i>

77
00:07:57,880 --> 00:07:59,480
<i>even decades later.</i>

78
00:08:03,680 --> 00:08:05,760
<i>It was a long day of marching,</i>

79
00:08:06,480 --> 00:08:09,640
<i>and everyone is desperate for water.</i>

80
00:08:13,800 --> 00:08:19,600
<i>Just like all the other 130 thousand</i>
<i>elephants living in Botswana.</i>

81
00:08:31,280 --> 00:08:34,800
<i>The dry season attracts herds</i>
<i>who come from far away...</i>

82
00:08:39,840 --> 00:08:42,000
<i>to this pond.</i>

83
00:08:52,160 --> 00:08:56,360
<i>Everyone competing</i>
<i>for the same scarce resource.</i>

84
00:09:15,120 --> 00:09:19,280
<i>Adults teach younger people</i>
<i>survival tricks</i>

85
00:09:20,000 --> 00:09:24,560
<i>how to slip your trunk into a pool</i>
<i>muddy to get cooler water.</i>

86
00:09:29,240 --> 00:09:34,080
<i>And how to use muddy water</i>
<i>as a refreshing sunscreen.</i>

87
00:09:36,880 --> 00:09:40,800
<i>Wrinkled skin is perfect</i>
<i>to retain water and keep cool.</i>

88
00:09:49,480 --> 00:09:53,080
<i>But so are Metsi and Bosigo</i>
<i>learning…</i>

89
00:09:56,080 --> 00:09:58,600
<i>that mud pools are not just useful</i>
<i>to quench their thirst.</i>

90
00:10:00,080 --> 00:10:01,840
<i>There are water parks too.</i>

91
00:10:15,000 --> 00:10:16,960
<i>With so many thirsty elephants,</i>

92
00:10:17,480 --> 00:10:19,720
<i>the lagoon was drained.</i>

93
00:10:26,160 --> 00:10:28,280
<i>Pula’s family needs to continue…</i>

94
00:10:31,840 --> 00:10:34,160
<i>and try to get to the next marsh</i>

95
00:10:34,800 --> 00:10:37,600
<i>before the scorching sun dries it out.</i>

96
00:10:40,720 --> 00:10:44,080
<i>This battle between sun and arid land</i>

97
00:10:44,160 --> 00:10:47,680
<i>it has existed since our world was born.</i>

98
00:10:52,040 --> 00:10:56,000
<i>When our blue planet was</i>
<i>everything but blue.</i>

99
00:11:04,160 --> 00:11:06,960
<i>Four and a half billion years ago…</i>

100
00:11:12,600 --> 00:11:15,160
<i>Earth was in its infancy.</i>

101
00:11:16,640 --> 00:11:19,000
<i>It was a fireball of molten rock.</i>

102
00:11:23,440 --> 00:11:27,480
<i>Destined to become</i>
<i>a dry and sterile world.</i>

103
00:11:31,440 --> 00:11:35,880
<i>But, millions of kilometers away,</i>
<i>in the coldest regions of the solar system…</i>

104
00:11:41,040 --> 00:11:42,720
<i>water crystals formed</i>

105
00:11:43,680 --> 00:11:46,760
<i>on the surface of dust particles.</i>

106
00:11:54,480 --> 00:11:59,760
<i>Over time, these dust grains</i>
<i>grouped together to form asteroids.</i>

107
00:12:01,520 --> 00:12:04,080
<i>Millions and millions of them.</i>

108
00:12:06,080 --> 00:12:09,600
<i>And they formed the asteroid belt.</i>

109
00:12:11,240 --> 00:12:14,440
<i>A vast expanse of icy rocks.</i>

110
00:12:17,640 --> 00:12:22,000
<i>However, they were tempting</i>
<i>outside the reach of Earth.</i>

111
00:12:25,880 --> 00:12:27,680
<i>Fortunately, luckily,</i>

112
00:12:28,400 --> 00:12:30,280
<i>a giant was on the move.</i>

113
00:12:34,720 --> 00:12:39,000
JUPITER
4.5 BILLION YEARS AGO

114
00:12:39,080 --> 00:12:40,280
<i>Young Jupiter.</i>

115
00:12:41,160 --> 00:12:43,120
<i>A planet monster.</i>

116
00:12:48,080 --> 00:12:51,160
<i>Forces within</i>
<i>from its turbulent inner solar system</i>

117
00:12:51,720 --> 00:12:55,520
<i>they slowly pulled it towards the Sun.</i>

118
00:13:00,760 --> 00:13:03,880
<i>A flight path</i>
<i>which put him on a collision course</i>

119
00:13:04,760 --> 00:13:06,480
<i>with the asteroid belt.</i>

120
00:13:22,080 --> 00:13:24,720
<i>As he passed the asteroids…</i>

121
00:13:28,480 --> 00:13:34,000
<i>its enormous gravitational force</i>
<i>threw rocks in all directions.</i>

122
00:13:41,880 --> 00:13:46,160
<i>And yet</i>
<i>from all this chaos and destruction,</i>

123
00:13:46,240 --> 00:13:49,040
<i>the supreme cosmic gift has come.</i>

124
00:13:55,120 --> 00:13:57,640
<i>Icy, water-rich rocks</i>

125
00:13:58,200 --> 00:14:00,840
<i>were launched towards Earth.</i>

126
00:14:06,360 --> 00:14:11,360
<i>Bringing the promise of life</i>
<i>one step closer.</i>

127
00:14:15,640 --> 00:14:17,320
<i>Over billions of years,</i>

128
00:14:17,400 --> 00:14:21,920
<i>the asteroids were intertwined</i>
<i>to the fabric of the Earth as it formed.</i>

129
00:14:25,680 --> 00:14:29,240
<i>Caught in the turmoil caused</i>
<i>by Jupiter</i>

130
00:14:30,920 --> 00:14:34,360
<i>and pushed into the depths</i>
<i>from Earth by asteroids,</i>

131
00:14:35,800 --> 00:14:39,800
<i>water molecules did not have</i>
<i>an easy journey to get here.</i>

132
00:14:42,760 --> 00:14:45,520
<i>They still had</i>
<i>a long way to go.</i>

133
00:14:46,320 --> 00:14:49,400
<i>Imprisoned for millions of years,</i>

134
00:14:50,200 --> 00:14:52,720
<i>trapped in the Earth's molten core...</i>

135
00:14:55,640 --> 00:14:57,480
<i>waiting for another miracle…</i>

136
00:15:00,600 --> 00:15:02,000
<i>to be released.</i>

137
00:15:12,040 --> 00:15:15,960
<i>Today, much of the water</i>
<i>Earth is still underground.</i>

138
00:15:23,880 --> 00:15:29,000
<i>So elephants developed</i>
<i>special abilities to find it.</i>

139
00:15:39,400 --> 00:15:41,960
<i>Even the muddy pools are empty.</i>

140
00:15:43,240 --> 00:15:46,120
<i>This dry period is over</i>
<i>a total drought.</i>

141
00:15:49,560 --> 00:15:51,880
<i>But Pula has a superpower.</i>

142
00:15:54,200 --> 00:15:55,720
<i>Your incredible trunk,</i>

143
00:15:57,240 --> 00:15:59,880
<i>filled with millions</i>
<i>sensory receptors…</i>

144
00:16:01,880 --> 00:16:05,120
<i>you can smell the water</i>
<i>kilometers away…</i>

145
00:16:09,040 --> 00:16:13,000
<i>and indicate your sources</i>
<i>well below the surface.</i>

146
00:16:23,720 --> 00:16:25,480
<i>But you have to dig.</i>

147
00:16:33,880 --> 00:16:35,720
<i>Metsi is not a great digger.</i>

148
00:16:40,840 --> 00:16:43,120
<i>But Bosigo has talent.</i>

149
00:16:51,520 --> 00:16:54,680
<i>And Metsi gets a seat at the bar.</i>

150
00:17:00,360 --> 00:17:03,240
<i>These few sips will not satisfy you.</i>

151
00:17:07,280 --> 00:17:10,160
<i>But if there wasn't water</i>
<i>stuck in the earth,</i>

152
00:17:11,520 --> 00:17:13,240
<i>there would be nothing to drink.</i>

153
00:17:17,800 --> 00:17:19,680
<i>There would be no elephants.</i>

154
00:17:23,200 --> 00:17:25,280
<i>And no kind of life.</i>

155
00:17:37,800 --> 00:17:41,160
<i>After the water has been drained</i>
<i>delivered here by asteroids</i>

156
00:17:41,240 --> 00:17:43,480
<i>and consumed by the Earth…</i>

157
00:17:45,640 --> 00:17:48,280
<i>it got stuck in the rock in the form of crystals…</i>

158
00:17:50,280 --> 00:17:51,880
<i>in the depths of the planet.</i>

159
00:17:57,560 --> 00:18:00,160
<i>It was buried for millions of years,</i>

160
00:18:01,160 --> 00:18:04,360
<i>under a vast sea of magma.</i>

161
00:18:12,920 --> 00:18:17,880
<i>Until, slowly, the Earth cooled.</i>

162
00:18:21,360 --> 00:18:25,880
<i>And its surface hardened</i>
<i>forming a thick crust.</i>

163
00:18:29,680 --> 00:18:34,240
<i>Until finally</i>
<i>the bubbly interior erupted.</i>

164
00:18:43,720 --> 00:18:45,600
<i>Huge volcanoes</i>

165
00:18:47,080 --> 00:18:51,120
<i>released gas and steam</i>
<i>for miles in the sky.</i>

166
00:18:58,720 --> 00:19:01,520
<i>At last the water molecules</i>

167
00:19:03,120 --> 00:19:04,280
<i>have been released.</i>

168
00:19:11,080 --> 00:19:13,800
<i>And the first clouds formed…</i>

169
00:19:18,480 --> 00:19:21,680
<i>that grew and formed</i>
<i>for millions of years,</i>

170
00:19:21,760 --> 00:19:23,400
<i>being charged with water.</i>

171
00:19:28,320 --> 00:19:31,560
<i>Until the temperature dropped enough…</i>

172
00:19:38,960 --> 00:19:41,480
<i>to the first drop of rain…</i>

173
00:19:46,920 --> 00:19:50,560
<i>form and fall.</i>

174
00:20:08,800 --> 00:20:11,080
<i>What followed was a deluge…</i>

175
00:20:16,240 --> 00:20:18,640
<i>which lasted thousands of years.</i>

176
00:20:30,040 --> 00:20:32,080
<i>Puddles turned into rivers.</i>

177
00:20:41,520 --> 00:20:42,720
<i>Lagos</i>

178
00:20:44,480 --> 00:20:46,000
<i>they became seas.</i>

179
00:20:53,480 --> 00:20:57,720
<i>And great oceans flooded</i>
<i>the surface of the Earth.</i>

180
00:21:15,920 --> 00:21:20,240
<i>And here, the water gave rise to something magical.</i>

181
00:21:25,320 --> 00:21:26,840
<i>The first life.</i>

182
00:21:31,080 --> 00:21:33,240
<i>From these first cells</i>

183
00:21:35,000 --> 00:21:38,040
<i>all living beings appeared.</i>

184
00:21:40,640 --> 00:21:43,960
<i>Water is the fundamental ingredient</i>

185
00:21:44,040 --> 00:21:48,000
<i>from every cell, from every creature on Earth.</i>

186
00:21:57,360 --> 00:21:58,440
<i>And today…</i>

187
00:22:01,320 --> 00:22:06,480
<i>the herd still carries</i>
<i>this ancient water inside her.</i>

188
00:22:18,040 --> 00:22:20,320
<i>It transports nutrients and oxygen.</i>

189
00:22:30,200 --> 00:22:32,280
<i>Boosts every heartbeat.</i>

190
00:22:38,920 --> 00:22:41,160
<i>And guides each breath.</i>

191
00:22:46,640 --> 00:22:49,840
<i>Life evolved because of water.</i>

192
00:22:51,000 --> 00:22:55,160
<i>And that's why</i>
<i>that no life survives without it.</i>

193
00:23:01,920 --> 00:23:03,160
<i>In Botswana,</i>

194
00:23:03,720 --> 00:23:05,520
<i>the drought only gets worse.</i>

195
00:23:11,080 --> 00:23:13,880
<i>The elephant world is on fire.</i>

196
00:23:22,600 --> 00:23:25,520
<i>The herd manages to escape</i>
<i>from the burning forest…</i>

197
00:23:29,040 --> 00:23:31,240
<i>but faces a new threat.</i>

198
00:23:37,560 --> 00:23:40,400
<i>In this drought, everyone suffers…</i>

199
00:23:43,680 --> 00:23:46,200
<i>from hunger and thirst.</i>

200
00:23:52,600 --> 00:23:57,080
<i>For the lions,</i>
<i>baby elephants do both.</i>

201
00:24:14,200 --> 00:24:17,320
<i>Adults Gather</i>
<i>around Metsi and Bosigo.</i>

202
00:24:24,720 --> 00:24:26,960
<i>It's enough to ward off the threat.</i>

203
00:24:30,680 --> 00:24:32,880
<i>But lions are patient creatures.</i>

204
00:24:36,880 --> 00:24:40,400
<i>And the herd still has to cross</i>
<i>a merciless desert…</i>

205
00:24:42,600 --> 00:24:44,360
<i>before the next pond.</i>

206
00:24:48,520 --> 00:24:50,880
<i>They need a lifeline.</i>

207
00:24:53,760 --> 00:24:56,040
<i>And the Earth provides this</i>

208
00:24:57,720 --> 00:25:00,120
<i>in the most unusual places.</i>

209
00:25:05,320 --> 00:25:08,080
<i>The acacia is a sign of hope.</i>

210
00:25:13,880 --> 00:25:16,800
<i>And a refuge for creatures</i>
<i>of all kinds.</i>

211
00:25:24,880 --> 00:25:30,400
<i>Its long roots reach deeper</i>
<i>that any elephant is capable of digging.</i>

212
00:25:41,240 --> 00:25:43,360
<i>Carrying water to its branches…</i>

213
00:25:47,360 --> 00:25:48,520
<i>and leaves.</i>

214
00:26:01,000 --> 00:26:04,480
<i>Is there enough water</i>
<i>so they can continue.</i>

215
00:26:08,280 --> 00:26:10,840
<i>But especially vital</i>
<i>to Metsi's mother...</i>

216
00:26:12,760 --> 00:26:14,520
<i>who still breastfeeds her baby.</i>

217
00:26:18,320 --> 00:26:21,880
<i>But this is much more</i>
<i>than just a local oasis.</i>

218
00:26:25,360 --> 00:26:28,560
<i>It is the vital link in the eternal water cycle.</i>

219
00:26:32,720 --> 00:26:36,800
<i>The acacia tree connects the ground and the sky.</i>

220
00:26:43,600 --> 00:26:46,080
<i>Breathing oxygen and vapor in the air.</i>

221
00:26:55,000 --> 00:26:59,320
<i>Powering clouds and boosting</i>
<i>water's journey around the planet.</i>

222
00:27:07,400 --> 00:27:09,040
<i>As long as the rain</i>

223
00:27:10,160 --> 00:27:12,600
<i>fed the first green shoots…</i>

224
00:27:16,320 --> 00:27:18,840
<i>and gave life to the first tree…</i>

225
00:27:24,120 --> 00:27:27,720
<i>the plants became</i>
<i>our habitable planet.</i>

226
00:27:35,280 --> 00:27:40,040
<i>Bringing life to what once was</i>
<i>a sterile stone ball.</i>

227
00:27:45,880 --> 00:27:48,760
<i>But the gifts</i>
<i>that our Universe gave us</i>

228
00:27:50,320 --> 00:27:52,760
<i>can also be taken back.</i>

229
00:28:01,280 --> 00:28:02,760
<i>A long time ago,</i>

230
00:28:04,080 --> 00:28:09,600
<i>there was another planet whose surface was</i>
<i>covered in liquid water.</i>

231
00:28:12,680 --> 00:28:17,280
MARS
3.5 BILLION YEARS AGO

232
00:28:18,080 --> 00:28:20,720
<i>A world of water, just like ours.</i>

233
00:28:25,720 --> 00:28:28,440
<i>The same forces</i>
<i>who brought water to Earth</i>

234
00:28:29,440 --> 00:28:32,080
<i>they also took them to Mars.</i>

235
00:28:35,200 --> 00:28:37,440
<i>With an existing atmosphere,</i>

236
00:28:37,520 --> 00:28:38,840
<i>clouds formed.</i>

237
00:28:40,480 --> 00:28:41,480
<i>Rain fell.</i>

238
00:28:43,000 --> 00:28:44,440
<i>Rivers flowed.</i>

239
00:28:48,800 --> 00:28:52,240
<i>And an ocean appeared on its surface.</i>

240
00:28:57,240 --> 00:28:59,960
<i>It was a world of possibilities.</i>

241
00:29:00,040 --> 00:29:02,320
<i>There was potential to harbor life.</i>

242
00:29:06,600 --> 00:29:08,080
<i>But it didn't last long.</i>

243
00:29:13,720 --> 00:29:19,520
<i>Because, not far from there,</i>
<i>there was a raging nuclear furnace.</i>

244
00:29:21,040 --> 00:29:22,040
<i>Our Sun.</i>

245
00:29:24,120 --> 00:29:29,800
<i>It releases streams of particles</i>
<i>high energy so powerful and deadly...</i>

246
00:29:32,480 --> 00:29:34,600
<i>which can devastate planets.</i>

247
00:29:43,960 --> 00:29:47,840
<i>This solar wind crosses space…</i>

248
00:29:52,320 --> 00:29:55,680
<i>at four hundred kilometers per second.</i>

249
00:30:00,480 --> 00:30:03,160
<i>And this destroyed the atmosphere of Mars,</i>

250
00:30:04,640 --> 00:30:06,800
<i>getting rid of water molecules.</i>

251
00:30:15,040 --> 00:30:16,160
<i>Little by little,</i>

252
00:30:16,680 --> 00:30:18,360
<i>over millions of years,</i>

253
00:30:19,600 --> 00:30:24,480
<i>the planet's protective layer was</i>
<i>destroyed by the wrath of the Sun.</i>

254
00:30:29,680 --> 00:30:31,640
<i>Until its ocean evaporated…</i>

255
00:30:37,640 --> 00:30:41,040
<i>and its water was lost in space.</i>

256
00:30:48,600 --> 00:30:54,280
<i>Mars turned into a shadow</i>
<i>desolate and frozen than it once was.</i>

257
00:31:03,360 --> 00:31:06,000
<i>Consumed by dust storms.</i>

258
00:31:12,520 --> 00:31:14,800
<i>Any chance of a complex life</i>

259
00:31:16,480 --> 00:31:18,360
<i>gone forever.</i>

260
00:31:27,560 --> 00:31:29,880
<i>That could have been</i>
<i>our story too.</i>

261
00:31:44,360 --> 00:31:46,760
<i>But somehow on Earth,</i>

262
00:31:47,560 --> 00:31:51,720
<i>water and life found</i>
<i>a way to hold on.</i>

263
00:32:06,320 --> 00:32:07,560
<i>In Botswana,</i>

264
00:32:08,120 --> 00:32:10,640
<i>after two hundred days under the scorching sun…</i>

265
00:32:12,840 --> 00:32:15,000
<i>there is no trace of water.</i>

266
00:32:23,680 --> 00:32:27,800
<i>Violent winds transform the arid land</i>
<i>in a dust storm.</i>

267
00:32:45,320 --> 00:32:49,440
<i>And the fight of the elephants</i>
<i>didn't go unnoticed.</i>

268
00:33:02,920 --> 00:33:06,880
<i>In daylight, adults can do it</i>
<i>protect your puppies.</i>

269
00:33:18,240 --> 00:33:19,800
<i>But when night falls…</i>

270
00:33:25,480 --> 00:33:26,920
<i>the story is different.</i>

271
00:33:37,600 --> 00:33:40,640
<i>Lions are masters</i>
<i>chaos and confusion.</i>

272
00:33:53,440 --> 00:33:55,880
<i>They choose the most vulnerable target.</i>

273
00:34:00,800 --> 00:34:02,120
<i>Working in a group.</i>

274
00:34:08,200 --> 00:34:10,560
<i>Until there's nowhere left to run.</i>

275
00:34:27,240 --> 00:34:29,760
<i>Without the herd as protection,</i>

276
00:34:30,960 --> 00:34:34,080
<i>lions dominate their prey.</i>

277
00:34:36,880 --> 00:34:40,640
<i>The drought and the endless search</i>
<i>for food and water</i>

278
00:34:41,440 --> 00:34:44,880
<i>they cost Bosigo his life.</i>

279
00:34:55,040 --> 00:34:58,360
<i>Elephants form</i>
<i>deep emotional bonds.</i>

280
00:35:09,920 --> 00:35:13,200
<i>The whole family mourns Bosigo's death.</i>

281
00:35:30,480 --> 00:35:32,840
<i>The herd gathers to comfort Metsi…</i>

282
00:35:34,760 --> 00:35:36,960
<i>who feels more than everyone.</i>

283
00:35:48,480 --> 00:35:52,480
<i>The never-ending fight</i>
<i>for survival happens every year.</i>

284
00:35:54,280 --> 00:35:55,720
<i>All over Okavango…</i>

285
00:35:58,000 --> 00:35:59,320
<i>all over our planet…</i>

286
00:36:01,960 --> 00:36:03,040
<i>and beyond.</i>

287
00:36:07,080 --> 00:36:09,560
<i>But, in this battle for survival,</i>

288
00:36:10,440 --> 00:36:12,000
<i>Earth was very lucky...</i>

289
00:36:14,000 --> 00:36:17,440
<i>with a secret guardian who protects her.</i>

290
00:36:24,360 --> 00:36:25,640
<i>In its depths…</i>

291
00:36:28,520 --> 00:36:34,360
<i>the raging molten furnace</i>
<i>the planet burns and shakes…</i>

292
00:36:37,840 --> 00:36:40,240
<i>generating a powerful magnetic field</i>

293
00:36:41,920 --> 00:36:44,360
<i>which extends from the heart of the planet</i>

294
00:36:46,160 --> 00:36:50,800
<i>up to sixty-five thousand kilometers</i>
<i>towards the Sun.</i>

295
00:36:52,600 --> 00:36:55,880
<i>A field of vital force</i>
<i>that defends the Earth…</i>

296
00:36:58,320 --> 00:37:01,040
<i>from the same violent solar winds</i>

297
00:37:02,080 --> 00:37:04,160
<i>that swept the water from Mars…</i>

298
00:37:10,480 --> 00:37:13,920
<i>defeating them before they hit</i>
<i>our atmosphere.</i>

299
00:37:26,520 --> 00:37:28,760
<i>Protecting our essential water.</i>

300
00:37:30,520 --> 00:37:31,920
<i>Embracing every drop</i>

301
00:37:32,880 --> 00:37:34,320
<i>close to our planet.</i>

302
00:37:41,040 --> 00:37:46,160
<i>This is what makes our dot light blue</i>
<i>different from anything else.</i>

303
00:37:49,520 --> 00:37:52,920
<i>A place where life can thrive.</i>

304
00:37:56,960 --> 00:37:59,080
<i>Bringing relief to elephants.</i>

305
00:38:01,600 --> 00:38:04,880
<i>Ensuring the rains return</i>
<i>every year without fail.</i>

306
00:38:09,680 --> 00:38:14,000
<i>In the distance,</i>
<i>rain clouds are forming.</i>

307
00:38:29,200 --> 00:38:33,800
<i>Elephants can detect</i>
<i>the low frequency of thunder</i>

308
00:38:33,880 --> 00:38:36,720
<i>two hundred and forty kilometers</i>
<i>away.</i>

309
00:38:43,400 --> 00:38:47,920
<i>And that means it's time</i>
<i>to return to Okavango.</i>

310
00:38:56,600 --> 00:38:58,560
<i>From the plateaus of Angola,</i>

311
00:39:00,200 --> 00:39:03,080
<i>water weaves its way through Botswana.</i>

312
00:39:12,000 --> 00:39:14,280
<i>To rejuvenate the delta…</i>

313
00:39:22,640 --> 00:39:24,720
<i>with the kiss of life.</i>

314
00:39:34,480 --> 00:39:37,480
<i>Every step brings the herd closer to home...</i>

315
00:39:40,760 --> 00:39:45,760
<i>is the continuation of a cosmic odyssey</i>
<i>much bigger.</i>

316
00:39:51,640 --> 00:39:57,280
<i>From small molecules hitchhiking</i>
<i>in the dust beyond Jupiter...</i>

317
00:40:02,960 --> 00:40:05,800
<i>until survival</i>
<i>to the overwhelming heat of ancient Earth.</i>

318
00:40:13,680 --> 00:40:16,160
<i>Imprisoned in the planet's core...</i>

319
00:40:18,200 --> 00:40:23,320
<i>and then released</i>
<i>to sow the seed of life.</i>

320
00:40:27,360 --> 00:40:31,880
<i>Every drop of water has</i>
<i>an incredible story to tell.</i>

321
00:40:34,640 --> 00:40:39,120
<i>Each molecule is a link</i>
<i>in a continuous chain,</i>

322
00:40:40,440 --> 00:40:43,400
<i>traversing tens of thousands of years.</i>

323
00:40:46,480 --> 00:40:47,800
<i>By air…</i>

324
00:40:50,840 --> 00:40:51,800
<i>oceans…</i>

325
00:40:55,680 --> 00:40:56,560
<i>rocks…</i>

326
00:41:04,800 --> 00:41:05,960
<i>and elephants.</i>

327
00:41:11,680 --> 00:41:13,040
<i>After eight months</i>

328
00:41:14,400 --> 00:41:16,240
<i>and hundreds of kilometers,</i>

329
00:41:17,720 --> 00:41:20,120
<i>Metsi and her family finally</i>

330
00:41:21,040 --> 00:41:24,960
<i>they reach the life-giving waters of the delta.</i>

331
00:41:38,040 --> 00:41:41,640
<i>It's past time to drink...</i>

332
00:41:43,880 --> 00:41:45,080
<i>and play.</i>

333
00:41:47,360 --> 00:41:50,160
<i>And then drink some more.</i>

334
00:41:59,560 --> 00:42:02,040
<i>And show it to the newest member of the family…</i>

335
00:42:06,360 --> 00:42:09,360
<i>how they do things in the delta.</i>

336
00:42:22,360 --> 00:42:24,960
<i>Metsi and her new baby cousin</i>

337
00:42:25,600 --> 00:42:28,240
<i>they are the last in a long line</i>

338
00:42:28,320 --> 00:42:31,640
<i>who benefit</i>
<i>the miraculous arrival of water</i>

339
00:42:32,840 --> 00:42:33,960
<i>to this planet.</i>

340
00:42:44,480 --> 00:42:47,800
<i>They will be connected</i>
<i>forever to the Universe,</i>

341
00:42:48,800 --> 00:42:52,360
<i>what he gave to our planet</i>
<i>that magical ingredient</i>

342
00:42:54,040 --> 00:42:57,680
<i>and gave us the ability to preserve it</i>

343
00:42:58,880 --> 00:43:00,200
<i>and value it.</i>

344
00:43:10,840 --> 00:43:15,280
<i>In the next episode</i>
<i>from </i>Enigmas of the Universe, <i>we will conclude…</i>

345
00:43:16,280 --> 00:43:22,160
<i>with the force that unites everything</i>
<i>what we've seen so far.</i>

00:43:23,560 --> 00:43:26,320
<i>The great sculptor of the cosmos:</i>

347
00:43:26,960 --> 00:43:27,800
<i>gravity.</i>

348
00:43:29,160 --> 00:43:32,680
<i>The force of attraction</i>
<i>who built our planet.</i>

349
00:43:35,560 --> 00:43:39,000
<i>And let's bring two penguins together</i>
<i>at the South Pole of the Earth.</i>

350
00:43:40,960 --> 00:43:44,720
<i>But when gravity started</i>
<i>to exert its influence?</i>

351
00:43:45,680 --> 00:43:47,440
<i>How it creates order</i>

352
00:43:49,000 --> 00:43:50,280
<i>and the chaos?</i>

353
00:43:52,920 --> 00:43:57,720
<i>And why does that make it</i>
<i>our perfect planet for life…</i>

354
00:43:59,920 --> 00:44:00,920
<i>and for love?</i>
