1
00:00:07,341 --> 00:00:09,841
地球如此壯觀

2
00:00:10,636 --> 00:00:13,676
很容易就錯過生活中比較小的東西

3
00:00:15,766 --> 00:00:17,636
但看仔細一點

4
00:00:18,143 --> 00:00:20,563
就會看見一整個未經探索的世界

5
00:00:22,648 --> 00:00:24,978
這個世界裡的小英雄

6
00:00:26,485 --> 00:00:27,815
以及小怪物

7
00:00:29,029 --> 00:00:31,409
需要驚人的超能力

8
00:00:34,618 --> 00:00:40,038
方能勝出,以小搏大

9
00:00:43,293 --> 00:00:48,843
《你不知道的小小世界》

10
00:00:55,347 --> 00:00:56,887
生活的步調很快

11
00:00:56,974 --> 00:00:58,104
(旁白,保羅路德)

12
00:00:58,183 --> 00:00:59,813
特別是對小生物而言

13
00:01:03,105 --> 00:01:05,515
這隻小花栗鼠幾乎才一個月大

14
00:01:06,775 --> 00:01:09,065
但牠若能活超過一年就算幸運

15
00:01:12,865 --> 00:01:14,905
有太多東西值得探索

16
00:01:16,869 --> 00:01:18,289
時間卻太少

17
00:01:23,292 --> 00:01:26,922
牠在北美森林中的棲息地即將蓬勃發展

18
00:01:31,258 --> 00:01:32,888
有小小的生物

19
00:01:33,635 --> 00:01:35,465
與大大的機會

20
00:01:45,731 --> 00:01:49,941
但小生命可能一轉眼就消逝

21
00:02:05,751 --> 00:02:06,961
必須拔腿就跑

22
00:02:18,639 --> 00:02:19,719
跑得快一點

23
00:02:27,064 --> 00:02:28,074
學得快一點

24
00:02:32,402 --> 00:02:34,912
你或許就能活過這一年

25
00:02:42,371 --> 00:02:46,581
《林地》

26
00:02:55,092 --> 00:02:56,302
早春

27
00:02:58,262 --> 00:03:00,352
阿帕拉契山脈的森林

28
00:03:00,430 --> 00:03:02,060
才剛開始欣欣向榮

29
00:03:11,567 --> 00:03:13,607
在這裡有很多食物

30
00:03:13,694 --> 00:03:17,414
一隻巴掌大小的花栗鼠
只需要約兩千平方公尺的地盤

31
00:03:28,584 --> 00:03:30,254
核果尤其不虞匱乏

32
00:03:34,298 --> 00:03:36,928
它們是推動這個小世界的推手

33
00:03:39,928 --> 00:03:44,138
在秋天,它們成熟時
就會成為天上掉下來的大禮

34
00:03:48,478 --> 00:03:50,898
但在此之前,牠得處理很多問題

35
00:03:59,740 --> 00:04:02,410
一隻較年長也較強壯的公鼠已經以此為家

36
00:04:06,955 --> 00:04:08,785
若這隻小花栗鼠想活下去

37
00:04:09,249 --> 00:04:12,249
牠必須及早懂得保護自己

38
00:04:15,088 --> 00:04:16,628
但打架很危險

39
00:04:18,841 --> 00:04:21,851
牠不能在早春就受傷

40
00:04:49,790 --> 00:04:51,500
牠必須保持低調

41
00:04:52,292 --> 00:04:54,092
在邊緣苟且偷生

42
00:04:58,131 --> 00:05:00,181
直到體型大到能保護自己

43
00:05:06,849 --> 00:05:10,059
對大多數動物而言
春天是外出覓食的時刻

44
00:05:14,147 --> 00:05:17,857
小動物的新陳代謝很快
因此必須更常進食

45
00:05:20,988 --> 00:05:22,818
毛毛蟲很貪吃

46
00:05:23,949 --> 00:05:25,909
鳥類也是

47
00:05:32,583 --> 00:05:36,003
吸汁啄木鳥啄出數百個洞
來吸取豐沛的樹液

48
00:05:39,423 --> 00:05:42,633
核桃大小的蜂鳥則完全坐享其成

49
00:05:48,473 --> 00:05:52,273
牠們飛行將近五千公里來到這裡

50
00:05:54,438 --> 00:05:57,648
剛好參與這場季節性的高糖食物派對

51
00:06:08,702 --> 00:06:10,912
大部分的森林生物萬分活躍

52
00:06:12,539 --> 00:06:15,169
有一位住戶依舊沉睡著

53
00:06:22,966 --> 00:06:25,586
捲曲在比蛋杯還小的空間中

54
00:06:26,053 --> 00:06:29,683
這隻跳鼠已經冬眠八個月

55
00:06:35,354 --> 00:06:37,564
現在,牠可能永遠不會醒來

56
00:06:44,530 --> 00:06:46,990
睡太久就會飢餓

57
00:06:49,535 --> 00:06:51,655
三分之二的跳鼠會出現這種情況

58
00:06:58,001 --> 00:07:01,171
然而牠的鄰居們從不休息

59
00:07:04,383 --> 00:07:06,843
牠們得餵飽好幾百張小嘴巴

60
00:07:15,102 --> 00:07:17,522
跟所有螞蟻一樣,牠們辛勤工作

61
00:07:18,105 --> 00:07:20,935
但真正的獨特之處,是牠們居住的地方

62
00:07:26,780 --> 00:07:29,990
牠們的體型宛如一粒沙,非常嬌小

63
00:07:30,075 --> 00:07:34,495
整群螞蟻可以住在一顆橡實中

64
00:07:46,633 --> 00:07:48,473
這看似完美的安全屋

65
00:07:51,054 --> 00:07:55,274
但以別人的食物為家似乎不是好主意

66
00:08:01,315 --> 00:08:03,145
巨獸在這片森林中行走

67
00:08:23,128 --> 00:08:24,338
野火雞

68
00:08:25,923 --> 00:08:28,593
保護幼蟲,緊抓不放的時候到了

69
00:08:33,931 --> 00:08:35,721
這或許會是一段顛簸的旅程

70
00:08:44,358 --> 00:08:46,608
至少橡實是堅固的住家

71
00:08:47,402 --> 00:08:49,702
而且本來就會滾動

72
00:09:06,713 --> 00:09:08,923
夏天很快就降臨在森林中

73
00:09:11,051 --> 00:09:12,681
翠綠又茂密

74
00:09:18,225 --> 00:09:21,645
然而,這隻小花栗鼠幾乎活不下去

75
00:09:25,399 --> 00:09:27,029
橡實依舊還沒成熟

76
00:09:34,032 --> 00:09:36,162
而且牠沒有自己的地盤

77
00:09:36,660 --> 00:09:39,290
只得在較年長公鼠的領土上覓食

78
00:09:44,459 --> 00:09:46,089
牠還沒準備好戰鬥

79
00:09:51,383 --> 00:09:52,633
牠必須變得強壯

80
00:10:02,394 --> 00:10:06,234
走投無路時,花栗鼠幾乎無所不吃

81
00:10:09,443 --> 00:10:11,033
或許連蛞蝓也不放過

82
00:10:20,329 --> 00:10:21,539
還是算了

83
00:10:23,540 --> 00:10:24,710
但牠不能久留

84
00:10:28,420 --> 00:10:30,630
上方有一個致命的威脅

85
00:10:35,344 --> 00:10:37,184
而且很快會有第二個

86
00:10:49,274 --> 00:10:52,494
目前,這隻小蒼鷹幾乎站不起來

87
00:10:53,529 --> 00:10:54,739
遑論飛翔

88
00:10:59,576 --> 00:11:02,076
牠一陣子之後才有能力獵補花栗鼠

89
00:11:09,127 --> 00:11:12,207
在下方,奇怪的東西正在孵化

90
00:11:24,893 --> 00:11:26,733
經過兩年的幼蟲時光

91
00:11:27,396 --> 00:11:31,396
體型相當於一顆高爾夫球的
海克力斯甲蟲正在冒出頭

92
00:11:43,579 --> 00:11:44,789
牠分秒必爭

93
00:11:46,707 --> 00:11:49,707
牠要占據最佳位置,才能找到交配對象

94
00:11:56,383 --> 00:11:57,473
但為何要用走的?

95
00:11:59,761 --> 00:12:00,971
你明明能飛

96
00:12:31,210 --> 00:12:33,340
身為世界上體重最重的昆蟲之一

97
00:12:33,962 --> 00:12:36,382
牠的翅膀肌肉必須徹底舒展

98
00:12:36,465 --> 00:12:38,045
才能飛上天

99
00:12:41,762 --> 00:12:43,392
目前用走的比較安全

100
00:12:46,308 --> 00:12:50,728
但這項艱鉅的任務
與橡實象蟲的任務相比看似簡單

101
00:12:51,897 --> 00:12:53,817
橡實象蟲的體型只有牠的百分之一

102
00:12:54,733 --> 00:12:57,693
但得走遠一千倍的路

103
00:13:09,039 --> 00:13:10,419
牠踏上一段史詩般的旅程

104
00:13:14,294 --> 00:13:16,134
為了抵達森林樹冠層

105
00:13:32,354 --> 00:13:34,864
全都是為了得到寶貴的橡實

106
00:13:36,316 --> 00:13:37,726
它們還沒成熟

107
00:13:40,612 --> 00:13:42,242
但牠不打算吃掉它們

108
00:13:45,659 --> 00:13:46,869
牠是要在裡面產卵

109
00:13:56,336 --> 00:13:58,666
牠只能在青澀的橡實上挖洞

110
00:14:06,138 --> 00:14:08,138
費盡千辛萬苦,只為了產一顆卵

111
00:14:13,187 --> 00:14:15,687
牠還得填滿很多顆橡實

112
00:14:29,578 --> 00:14:32,998
在森林地面上,跳鼠開始活動

113
00:14:36,126 --> 00:14:37,836
牠真的必須快點醒來

114
00:14:40,631 --> 00:14:43,931
目前,牠渾然不覺季節的轉換

115
00:14:44,635 --> 00:14:47,965
以及上方正在醞釀的戰役

116
00:14:54,811 --> 00:14:57,651
海克力斯甲蟲順利抵達圓木的頂端

117
00:15:04,321 --> 00:15:05,951
但沒有休息時間

118
00:15:08,742 --> 00:15:11,162
競爭對手緊跟在後

119
00:15:22,047 --> 00:15:24,377
牠們是地球上最強壯的甲蟲

120
00:15:26,844 --> 00:15:29,854
每隻可抬起本身體重100倍的重量

121
00:15:35,602 --> 00:15:38,862
目標是拎起對手,並從圓木丟下去

122
00:15:41,149 --> 00:15:43,529
昆蟲世界的相撲選手

123
00:16:41,210 --> 00:16:42,840
牠贏得這根圓木

124
00:16:45,297 --> 00:16:48,007
也贏得交配的機會

125
00:17:00,020 --> 00:17:03,270
這隻年輕蒼鷹的視力已經比人類好兩倍

126
00:17:05,901 --> 00:17:08,531
牠只有四週大,幾乎已經發育完成

127
00:17:17,037 --> 00:17:18,867
牠大部分的羽毛已經豐滿

128
00:17:24,377 --> 00:17:25,837
牠很快就能飛翔

129
00:17:30,425 --> 00:17:33,045
在此之前,這隻小花栗鼠可以放輕鬆

130
00:17:39,893 --> 00:17:41,103
但也別太輕鬆

131
00:17:43,105 --> 00:17:47,105
秋天一陣子之後才到來
那些橡實終於成熟了

132
00:17:57,327 --> 00:17:59,157
當仲夏夜降臨

133
00:18:00,080 --> 00:18:01,500
空氣中瀰漫著神奇的氣息

134
00:18:14,052 --> 00:18:18,642
數千隻小螢火蟲在黑暗中跳舞

135
00:18:29,526 --> 00:18:32,776
在牠的圓木裡,小跳鼠終於睡醒了

136
00:18:37,868 --> 00:18:40,698
但現在,牠就快餓死

137
00:18:41,830 --> 00:18:44,000
牠必須尋找食物

138
00:18:47,920 --> 00:18:49,920
那表示與暗夜搏鬥

139
00:18:59,556 --> 00:19:02,766
奇怪的東西在森林地面上蠢蠢欲動

140
00:19:07,147 --> 00:19:11,237
自然界最怪異的奇觀之一即將登場

141
00:19:15,197 --> 00:19:18,407
以幼蟲之姿在地底覓食17年之後

142
00:19:18,992 --> 00:19:21,202
蟬終於鑽出地表

143
00:19:24,206 --> 00:19:27,576
現在,牠們只有幾天可活

144
00:19:30,462 --> 00:19:31,842
比賽開始

145
00:19:38,679 --> 00:19:40,679
在地底獨自度過一輩子之後

146
00:19:41,265 --> 00:19:46,725
數百萬隻姆指大的蟬
挑這個時刻同時鑽出地表

147
00:19:51,859 --> 00:19:54,489
這是地球上規模最大的遷徙之一

148
00:19:57,239 --> 00:20:00,529
今晚,若蟲變態為成蟲

149
00:20:10,711 --> 00:20:14,461
明天,牠們會交配,然後死亡

150
00:20:24,141 --> 00:20:25,891
很多隻甚至活不過今晚

151
00:20:32,357 --> 00:20:36,567
但數量確保大部分的蟬
能活到繁殖的那一天

152
00:20:37,863 --> 00:20:39,913
同時森林中的生物依舊能飽餐一頓

153
00:20:46,163 --> 00:20:48,753
但跳鼠算是素食者

154
00:20:52,377 --> 00:20:55,377
牠在尋找小型種子與真菌

155
00:21:06,892 --> 00:21:09,652
森林響尾蛇可以好幾個月不進食

156
00:21:18,403 --> 00:21:22,373
現在,牠剛好能一口吞掉老鼠大小的獵物

157
00:21:29,039 --> 00:21:31,249
在黑暗中覓食充滿風險

158
00:21:35,504 --> 00:21:36,594
除非你有...

159
00:21:39,842 --> 00:21:41,182
秘密超能力

160
00:21:49,726 --> 00:21:53,556
牠似乎違反地心引力,可以跳到2公尺高

161
00:22:03,365 --> 00:22:07,825
腳與腿中的特大肌腱,加上嬌小的體型

162
00:22:08,912 --> 00:22:11,922
讓牠能跳離潛伏在森林中的危險

163
00:22:29,183 --> 00:22:32,313
希望能跳到比較安全的覓食區

164
00:22:46,950 --> 00:22:48,740
隨著夏去秋來

165
00:22:50,495 --> 00:22:53,365
森林進入了神奇的黃金時期

166
00:22:59,004 --> 00:23:01,804
但新的威脅也隨之出現

167
00:23:11,225 --> 00:23:13,265
年輕的蒼鷹羽翼已豐

168
00:23:19,858 --> 00:23:21,688
從毛頭小鳥

169
00:23:28,450 --> 00:23:29,870
變成空中殺手

170
00:23:34,957 --> 00:23:36,577
牠的翼展超過1公尺

171
00:23:38,126 --> 00:23:42,046
飛行時速可以高達60公里

172
00:23:57,479 --> 00:23:59,939
小動物最好注意天空

173
00:24:07,364 --> 00:24:08,874
不僅是防老鷹

174
00:24:17,624 --> 00:24:20,044
小花栗鼠期待許久的時刻到來了

175
00:24:26,550 --> 00:24:28,050
成熟的橡實

176
00:24:31,555 --> 00:24:35,635
這些天上掉下來的禮物只會持續一至兩週
所以該囤積了

177
00:24:40,814 --> 00:24:44,324
牠可以將好幾顆核果塞入超大的雙頰中

178
00:24:49,740 --> 00:24:53,370
當你需要數百顆過冬
這就是很寶貴的技能

179
00:24:59,416 --> 00:25:02,416
但牠囤積的速度似乎不夠快

180
00:25:09,092 --> 00:25:11,512
有人一直偷走牠的存貨

181
00:25:14,389 --> 00:25:15,599
比較年長的公鼠

182
00:25:23,106 --> 00:25:24,936
這個小傢伙庫存越多

183
00:25:29,571 --> 00:25:31,621
牠的鄰居就偷走越多

184
00:25:38,705 --> 00:25:39,915
最糟糕的是

185
00:25:43,252 --> 00:25:46,172
附近有很多核果都毫無價值

186
00:25:52,344 --> 00:25:55,104
橡實象蟲的幼蟲一直在裡面生長

187
00:25:58,892 --> 00:26:03,112
現在牠的大小宛如豆豆糖
該離開這間育嬰室了

188
00:26:07,818 --> 00:26:09,648
說比做容易

189
00:26:19,913 --> 00:26:22,003
連空的核果也不會被浪費

190
00:26:26,295 --> 00:26:30,125
這是給新一代橡實螞蟻的新家

191
00:26:41,810 --> 00:26:43,480
在牠舒適的圓木中

192
00:26:45,689 --> 00:26:48,689
跳鼠已經在鋪床

193
00:26:51,987 --> 00:26:54,237
牠才醒了幾個月

194
00:26:55,032 --> 00:26:57,662
現在又要大睡一覺

195
00:27:03,123 --> 00:27:04,963
但這隻小花栗鼠不能休息

196
00:27:06,835 --> 00:27:08,295
秋天快結束了

197
00:27:08,378 --> 00:27:11,218
牠活過冬天的機率看似渺茫

198
00:27:16,345 --> 00:27:17,675
牠需要更多核果

199
00:27:19,389 --> 00:27:20,889
只有一個解決方式

200
00:27:27,606 --> 00:27:29,816
現在該勇闖敵人的地盤了

201
00:27:39,993 --> 00:27:42,043
比較年長的公鼠或許願意偷竊

202
00:27:47,584 --> 00:27:49,804
但牠絕不願意分享

203
00:28:06,478 --> 00:28:09,108
這隻年輕的花栗鼠被逮個正著

204
00:28:14,319 --> 00:28:17,199
這塊林地不夠大,容不下牠們倆

205
00:28:30,127 --> 00:28:31,797
但牠逃不了一世

206
00:28:34,256 --> 00:28:35,876
該打鬥了

207
00:29:06,997 --> 00:29:09,917
這隻比較年長的公鼠
傷痕累累地落敗,逃之夭夭

208
00:29:18,842 --> 00:29:21,802
似乎牠短期內不會回來

209
00:29:32,606 --> 00:29:35,226
有時候當你很嬌小,生命或許短暫不已

210
00:29:40,113 --> 00:29:42,533
但這隻小花栗鼠正在努力享受每分每秒

211
00:29:45,077 --> 00:29:46,907
牠鞏固了自己的地盤

212
00:29:47,746 --> 00:29:49,456
收集到大量的核果

213
00:29:51,250 --> 00:29:54,380
並且克服了小動物面臨的挑戰

214
00:29:55,295 --> 00:29:57,255
在巨大的野生林地中生存下來

215
00:29:59,466 --> 00:30:01,836
準備好過冬所需的一切之後

216
00:30:04,429 --> 00:30:06,519
終於,牠能休息了

217
00:30:08,392 --> 00:30:10,812
夢想著另一個春天

218
00:31:07,659 --> 00:31:09,659
