1
00:00:00,000 --> 00:00:02,999
想一下您的智能手機或筆記本電腦，

2
00:00:03,611 --> 00:00:05,511
它們了解這一切。

3
00:00:05,517 --> 00:00:08,241
您知道裡面每個芯片的產地，

4
00:00:08,895 --> 00:00:09,965
然後... ...

5
00:00:09,965 --> 00:00:11,555
您就一無所知了。

6
00:00:11,555 --> 00:00:15,468
電子廢物的發生
是因為產品對我們不再有用，

7
00:00:15,468 --> 00:00:16,709
因此，我們將其丟棄。

8
00:00:16,709 --> 00:00:18,719
而我們加工和設計這些產品的方式

9
00:00:18,728 --> 00:00:21,078
則加劇了這個問題：

10
00:00:21,087 --> 00:00:23,337
因為難以拆開產品部件，

11
00:00:25,096 --> 00:00:26,826
而無法提取有用材料，

12
00:00:28,556 --> 00:00:29,603
並重新使用它們。

13
00:00:29,603 --> 00:00:31,917
[Music]管子接到底座上，

14
00:00:31,917 --> 00:00:34,073
底座組裝成大機箱[Music end]。

15
00:00:34,073 --> 00:00:37,724
聽說大約 4000 人在這里工作，

16
00:00:37,746 --> 00:00:40,436
我在此工作已有15年了。

17
00:00:43,239 --> 00:00:44,499
我們發現，

18
00:00:44,499 --> 00:00:47,448
他們中的大多數人
血液中的重金屬含量較高。

19
00:00:47,448 --> 00:00:48,538
我認為，

20
00:00:48,538 --> 00:00:52,860
不僅非洲正面臨電子廢物問題，

21
00:00:52,872 --> 00:00:57,802
因為電子和電氣設備
是我們日常生活的一部分。

22
00:00:57,811 --> 00:01:00,072
如果產品使用了兩至三年後

23
00:01:00,072 --> 00:01:03,403
我們就將其中的大部分產品丟棄，

24
00:01:03,403 --> 00:01:06,788
根本無法為將來生活在
地球上的 70 億、80 億或 90 億人

25
00:01:06,788 --> 00:01:08,252
提供這類產品。

26
00:01:51,438 --> 00:01:54,312
當然，我們說的電子垃圾是統稱，

27
00:01:54,312 --> 00:01:56,790
但具體到舊的CRT顯示器、

28
00:01:56,790 --> 00:01:59,970
或當代和時下的智能手機，
它們則有所不同。

29
00:01:59,970 --> 00:02:03,394
但是可以肯定的是，
能從電子垃圾中回收很多價值，

30
00:02:03,394 --> 00:02:05,455
而這恰好是回收的動力。

31
00:02:05,455 --> 00:02:06,727
我是麻省理工學院的教授，

32
00:02:06,727 --> 00:02:08,775
負責 Senseable City Lab 實驗室，

33
00:02:08,775 --> 00:02:11,415
和名為 Carlo Ratii Associati 的
一所設計辦公室，

34
00:02:11,415 --> 00:02:13,865
通過「垃圾跟踪」項目
開始著手這個問題。

35
00:02:13,868 --> 00:02:16,857
幾年前，我們與西雅圖市合作，

36
00:02:16,857 --> 00:02:19,457
在廢物上放置了很多電子標籤，

37
00:02:19,457 --> 00:02:20,720
以追踪廢物。

38
00:02:20,720 --> 00:02:22,400
我們追蹤香蕉皮、

39
00:02:22,408 --> 00:02:26,758
舊的CRT顯示器、電腦、墨盒等。

40
00:02:26,787 --> 00:02:30,047
很多廢物最終將流向美國邊界，

41
00:02:30,047 --> 00:02:32,027
然後，我們就無法追蹤了。

42
00:03:08,016 --> 00:03:09,901
我來到這裡的第一天就很震驚，

43
00:03:10,930 --> 00:03:13,320
您看到人們正在做什麼樣的工作，

44
00:03:15,432 --> 00:03:19,022
他們會割傷自己，
將自己暴露於那麼多事物中。

45
00:03:21,482 --> 00:03:24,262
我是 Bennett Nana Akuffo，

46
00:03:25,520 --> 00:03:28,771
是迦納綠色倡導項目的經理
（Green Advocacy Ghana）。

47
00:03:28,771 --> 00:03:31,711
這裡的男孩們
通常會跟隨卡車四處走，

48
00:03:31,958 --> 00:03:33,228
走街串巷。

49
00:03:33,228 --> 00:03:34,808
如果他們來我家，

50
00:03:34,810 --> 00:03:37,100
肯定會從我這裡買冰箱。

51
00:03:37,126 --> 00:03:39,866
然後，他們將冰箱帶到這裡，

52
00:03:39,931 --> 00:03:41,621
把冰箱切成碎片。

53
00:03:41,623 --> 00:03:43,743
他們從冰箱外殼中獲取鋁，

54
00:03:43,834 --> 00:03:47,774
從冰箱內的馬達中獲取銅。

55
00:03:48,176 --> 00:03:50,978
因此，他們的做法
是用錘子和鑿子將其切割，

56
00:03:51,483 --> 00:03:53,513
然後，找到其中的電纜，

57
00:03:53,526 --> 00:03:55,526
用燃燒的方法提取銅。

58
00:03:55,556 --> 00:03:57,746
而聚苯乙烯泡沫

59
00:03:57,765 --> 00:04:00,165
則被用作某種燃料。

60
00:04:00,179 --> 00:04:02,719
因此，如果需要處理那些金屬，

61
00:04:02,719 --> 00:04:05,947
他們會添加聚苯乙烯泡沫，
並將其點燃。

62
00:04:07,339 --> 00:04:09,708
這樣以來，我們都知道
土壤被高度污染，

63
00:04:09,708 --> 00:04:13,708
土壤中鉛、鎘和砷的含量不斷上升。

64
00:04:13,990 --> 00:04:16,890
我們對這裡的人做了一次健康調查，

65
00:04:16,978 --> 00:04:18,648


66
00:04:18,648 --> 00:04:21,251


67
00:04:21,337 --> 00:04:23,673


68
00:04:23,925 --> 00:04:25,325


69
00:04:25,567 --> 00:04:28,417


70
00:04:28,538 --> 00:04:31,188


71
00:04:31,329 --> 00:04:32,349


72
00:04:32,360 --> 00:04:34,930


73
00:04:35,185 --> 00:04:37,585


74
00:04:39,768 --> 00:04:43,768


75
00:04:43,923 --> 00:04:46,723


76
00:04:46,857 --> 00:04:48,937


77
00:04:51,715 --> 00:04:55,328


78
00:04:55,671 --> 00:04:59,671


79
00:04:59,871 --> 00:05:01,060


80
00:05:01,380 --> 00:05:03,360


81
00:05:03,360 --> 00:05:04,940


82
00:05:05,759 --> 00:05:07,765


83
00:05:07,765 --> 00:05:11,001


84
00:05:19,917 --> 00:05:22,087


85
00:05:22,087 --> 00:05:24,807


86
00:05:24,818 --> 00:05:25,888


87
00:05:25,888 --> 00:05:26,978


88
00:05:27,118 --> 00:05:30,003


89
00:05:30,003 --> 00:05:31,813


90
00:05:31,813 --> 00:05:35,006


91
00:05:35,006 --> 00:05:37,936


92
00:05:38,060 --> 00:05:41,480


93
00:05:41,486 --> 00:05:43,837


94
00:05:43,837 --> 00:05:45,706


95
00:05:45,706 --> 00:05:48,372


96
00:05:48,372 --> 00:05:50,572


97
00:05:50,572 --> 00:05:53,152


98
00:05:53,152 --> 00:05:54,902


99
00:05:54,902 --> 00:05:56,600


100
00:05:56,650 --> 00:05:59,663


101
00:05:59,860 --> 00:06:04,890


102
00:06:05,293 --> 00:06:07,953


103
00:06:07,953 --> 00:06:11,033


104
00:06:11,092 --> 00:06:13,432


105
00:06:13,477 --> 00:06:16,317


106
00:06:16,444 --> 00:06:18,594


107
00:06:18,601 --> 00:06:21,011


108
00:06:21,058 --> 00:06:23,558


109
00:06:23,589 --> 00:06:26,019


110
00:06:26,314 --> 00:06:32,126


111
00:06:32,749 --> 00:06:37,099


112
00:06:37,419 --> 00:06:40,069


113
00:06:40,247 --> 00:06:42,527


114
00:06:42,662 --> 00:06:45,742


115
00:06:56,867 --> 00:07:00,306


116
00:07:00,456 --> 00:07:03,056


117
00:07:03,078 --> 00:07:05,398


118
00:07:05,723 --> 00:07:09,723


119
00:07:10,632 --> 00:07:14,652


120
00:07:14,652 --> 00:07:17,686


121
00:07:17,763 --> 00:07:20,973


122
00:07:21,011 --> 00:07:22,851


123
00:07:22,863 --> 00:07:24,813


124
00:07:26,882 --> 00:07:28,362


125
00:07:28,370 --> 00:07:31,660


126
00:07:31,682 --> 00:07:34,632


127
00:07:47,098 --> 00:07:50,029


128
00:07:50,163 --> 00:07:52,448


129
00:07:52,449 --> 00:07:53,819


130
00:07:53,837 --> 00:07:56,687


131
00:07:57,006 --> 00:08:00,376


132
00:08:00,551 --> 00:08:02,941


133
00:08:03,053 --> 00:08:05,293


134
00:08:05,310 --> 00:08:11,439


135
00:08:11,439 --> 00:08:13,363


136
00:08:13,363 --> 00:08:15,065


137
00:08:15,065 --> 00:08:17,209


138
00:08:17,209 --> 00:08:19,963


139
00:08:19,963 --> 00:08:22,493


140
00:08:22,686 --> 00:08:26,066


141
00:08:26,066 --> 00:08:28,999


142
00:08:29,022 --> 00:08:30,912


143
00:08:31,332 --> 00:08:35,036
