1
00:00:00,400 --> 00:00:03,279
One box is about to cross the land between

2
00:00:03,279 --> 00:00:07,048
two oceans, and the ship
carrying it will go no further.

3
00:00:08,400 --> 00:00:11,365
Around eighty percent of global trade by

4
00:00:11,365 --> 00:00:15,960
volume goes by sea, so each box's
route shapes what reaches us.

5
00:00:16,400 --> 00:00:19,114
A lock is a chamber of water that lifts or

6
00:00:19,114 --> 00:00:22,280
lowers a ship to match the
level beyond its gates.

7
00:00:24,400 --> 00:00:27,104
Once the levels match, the gates open and

8
00:00:27,104 --> 00:00:30,928
the ship glides into a quiet
basin where its crossing ends.

9
00:00:32,400 --> 00:00:34,956
A quay crane lifts the box from the deck

10
00:00:34,956 --> 00:00:38,088
and sets it on a rail wagon
for the land crossing.

11
00:00:40,400 --> 00:00:43,080
The train carries the box along the land

12
00:00:43,080 --> 00:00:46,832
bridge, with an ocean on each
side and no water to cross.

13
00:00:48,400 --> 00:00:50,950
At the far end a gantry crane lifts the

14
00:00:50,950 --> 00:00:54,088
box from the wagon and
sets it on a yard tractor.

15
00:00:56,400 --> 00:00:58,780
The tractor carries the box along a

16
00:00:58,780 --> 00:01:03,744
service road past the stacks, toward
a fenced compound with one open gate.

17
00:01:04,400 --> 00:01:06,858
Inside that fence, the law generally

18
00:01:06,858 --> 00:01:11,912
treats the box as outside the customs
territory, so duty waits at the gate.

19
00:01:12,400 --> 00:01:15,037
The box leaves the way it arrived, because

20
00:01:15,037 --> 00:01:18,616
this crossing is not an event
but a loop that never stops.

21
00:01:20,400 --> 00:01:22,899
When every handoff along the route is

22
00:01:22,899 --> 00:01:27,288
built to hold, a box can change
oceans in one continuous movement.

23
00:01:28,400 --> 00:01:31,425
It was never six separate stops, only one

24
00:01:31,425 --> 00:01:35,336
path, and the dot you first
saw is sailing out to sea.
