1
00:00:07,250 --> 00:00:08,500
What would happen
2
00:00:08,667 --> 00:00:11,250
if every human being on earth...
3
00:00:12,458 --> 00:00:14,042
Disappeared?
4
00:00:14,208 --> 00:00:16,208
No matter how we might vanish,
5
00:00:16,375 --> 00:00:18,708
this is the story
of what could happen
6
00:00:18,875 --> 00:00:20,875
to the world we leave behind.
7
00:00:23,542 --> 00:00:26,042
Now,
8
00:00:26,208 --> 00:00:28,999
life after
people hits home.
9
00:00:32,333 --> 00:00:35,167
The buildings we live
in are our castles
10
00:00:35,375 --> 00:00:37,875
and they say, "Home is
where the heart is."
11
00:00:38,000 --> 00:00:40,583
But when we're gone,
what comes knocking?
12
00:00:43,458 --> 00:00:46,417
In vast suburbs, modern
houses are under assault
13
00:00:46,542 --> 00:00:50,667
from the outside and
from the inside out.
14
00:00:52,000 --> 00:00:54,750
It looks like the entire city
15
00:00:54,917 --> 00:00:57,042
was put in the
microwave on high.
16
00:00:57,208 --> 00:00:59,417
This house has
turned to Swiss cheese.
17
00:01:04,708 --> 00:01:08,042
Condominiums
everywhere get new residents
18
00:01:08,250 --> 00:01:09,125
by the thousands.
19
00:01:10,542 --> 00:01:13,458
Cockroaches will eat
literally anything.
20
00:01:13,625 --> 00:01:16,125
It's the home invasion
of your worst fears.
21
00:01:17,833 --> 00:01:19,457
No matter how well-built,
22
00:01:19,458 --> 00:01:23,375
every home would be
swallowed by decay.
23
00:01:23,542 --> 00:01:26,542
It shows you how delicate
paradise really is.
24
00:01:28,292 --> 00:01:29,999
And in the heartland,
25
00:01:30,000 --> 00:01:32,250
farmsteads that were
once the cornerstone
26
00:01:32,375 --> 00:01:36,750
of the American dream
become beastly nightmares.
27
00:01:36,875 --> 00:01:38,083
It's pretty incredible
28
00:01:38,208 --> 00:01:40,500
how quickly domesticated
pigs go feral.
29
00:01:41,833 --> 00:01:43,625
They look almost unrecognizable.
30
00:01:46,083 --> 00:01:48,124
In a world
without people,
31
00:01:48,125 --> 00:01:52,042
the places we lived are
taken over, taken down,
32
00:01:52,208 --> 00:01:54,875
and our most precious
memories are erased.
33
00:01:57,625 --> 00:01:59,000
Welcome to Earth.
34
00:01:59,167 --> 00:02:00,417
Population,
35
00:02:02,792 --> 00:02:04,000
zero.
36
00:02:13,458 --> 00:02:17,000
All around the globe,
homes are abandoned.
37
00:02:17,125 --> 00:02:20,583
From major cities like
Paris and Chicago
38
00:02:20,708 --> 00:02:23,708
to the suburbs and rural
areas that surround them.
39
00:02:25,500 --> 00:02:29,375
In Mesa, Arizona, the biggest
suburb in the United States,
40
00:02:29,542 --> 00:02:32,375
no children play in backyards,
41
00:02:32,542 --> 00:02:35,791
no parents stroll the sidewalks,
42
00:02:35,792 --> 00:02:37,625
the houses sit empty,
43
00:02:38,667 --> 00:02:40,124
every room is silent,
44
00:02:42,458 --> 00:02:45,458
every hallway eerily still.
45
00:02:46,250 --> 00:02:48,750
But one sound remains:
46
00:02:48,917 --> 00:02:53,417
the low hum of what once made
life in these homes possible,
47
00:02:53,542 --> 00:02:57,250
even in the brutal heat
of the Sonoran Desert:
48
00:02:58,083 --> 00:03:00,000
air conditioning.
49
00:03:00,167 --> 00:03:02,833
These deserts shouldn't
be fit for human life,
50
00:03:03,000 --> 00:03:05,333
but somehow, people
call them home.
51
00:03:05,500 --> 00:03:07,750
Air conditioning
is absolutely crucial
52
00:03:07,875 --> 00:03:09,833
in places as hot as Mesa.
53
00:03:09,958 --> 00:03:11,875
Lifeless and
scorched by the sun,
54
00:03:12,000 --> 00:03:13,958
humans rolled the
dice on the desert
55
00:03:14,083 --> 00:03:16,167
and forced it to
bend to our will.
56
00:03:17,042 --> 00:03:18,457
Most of these large houses
57
00:03:18,458 --> 00:03:20,125
are built with
black shingle roofs
58
00:03:20,292 --> 00:03:22,000
and giant picture windows.
59
00:03:22,208 --> 00:03:23,333
They look great
from the outside.
60
00:03:23,458 --> 00:03:24,917
Without air conditioning,
61
00:03:25,042 --> 00:03:26,958
those roofs suck up
heat from the sun
62
00:03:27,125 --> 00:03:29,375
and turn those upper
floors into a heat sink.
63
00:03:29,542 --> 00:03:32,333
Then, those picture windows
act like panes in a greenhouse,
64
00:03:32,500 --> 00:03:35,417
letting in sunlight and
trapping the heat inside.
65
00:03:35,542 --> 00:03:37,542
In the time of people,
66
00:03:37,708 --> 00:03:41,375
air conditioning was the
lifeblood of every home.
67
00:03:41,542 --> 00:03:45,917
Now, there's no one left
to adjust the temperature,
68
00:03:46,042 --> 00:03:49,083
no one to enjoy the cool.
69
00:03:49,208 --> 00:03:51,500
But 70 miles away,
70
00:03:51,625 --> 00:03:54,833
the electric heart of the
biggest nuclear power plant
71
00:03:54,958 --> 00:03:57,000
in the country still beats,
72
00:03:57,125 --> 00:04:00,042
powering the
surrounding suburbs:
73
00:04:00,208 --> 00:04:03,583
the Palo Verde Nuclear
Generating Station.
74
00:04:03,708 --> 00:04:06,083
Palo Verde is the only
desert nuclear plant
75
00:04:06,208 --> 00:04:07,374
in the Western Hemisphere
76
00:04:07,375 --> 00:04:08,667
and the only one in the country
77
00:04:08,833 --> 00:04:11,750
that's not located next to
a natural body of water.
78
00:04:13,000 --> 00:04:16,332
Most plants are built near
rivers, lakes, or oceans,
79
00:04:16,333 --> 00:04:19,583
so they can use that water
to cool their reactors.
80
00:04:20,500 --> 00:04:23,833
In the parched and
sweltering Arizona desert,
81
00:04:24,000 --> 00:04:28,708
humanity found another way to
cool Palo Verde's fuel rods,
82
00:04:28,875 --> 00:04:33,042
one that flows not through a
riverbend or along a coastline,
83
00:04:33,167 --> 00:04:34,500
but through the sewers.
84
00:04:34,667 --> 00:04:36,500
Instead of a
natural water source,
85
00:04:36,667 --> 00:04:38,833
Palo Verde has an
automated system
86
00:04:38,958 --> 00:04:40,458
that pulls treated sewage water
87
00:04:40,583 --> 00:04:43,708
from cities like
Phoenix, Mesa, and Tempe
88
00:04:43,833 --> 00:04:46,542
and pumps it into reservoirs
and cooling towers.
89
00:04:47,958 --> 00:04:49,666
Going to the bathroom in Mesa
90
00:04:49,667 --> 00:04:52,666
is almost like
performing a civic duty
91
00:04:52,667 --> 00:04:54,583
because every time
you flush your toilet,
92
00:04:54,708 --> 00:04:57,625
you're helping to cool
a nuclear reactor.
93
00:04:59,625 --> 00:05:02,292
The reactors
still hum with power
94
00:05:02,417 --> 00:05:04,417
not because of human hands,
95
00:05:04,542 --> 00:05:07,500
but because of the
systems they left behind,
96
00:05:07,625 --> 00:05:10,166
a web of automated fail-safes
97
00:05:10,167 --> 00:05:14,500
designed to keep the
unimaginable at bay.
98
00:05:14,625 --> 00:05:16,333
We all know the
names Chernobyl,
99
00:05:16,500 --> 00:05:18,500
Three Mile Island, Fukushima.
100
00:05:18,667 --> 00:05:20,750
'Cause they were
unbelievable disasters
101
00:05:20,875 --> 00:05:24,000
with far-reaching and
long-lasting consequences.
102
00:05:25,958 --> 00:05:27,125
Palo Verde Nuclear Plant
103
00:05:27,458 --> 00:05:30,542
was designed to prevent
exactly that kind of disaster.
104
00:05:30,667 --> 00:05:31,833
The Chernobyl disaster
105
00:05:32,042 --> 00:05:36,291
caused nearly 200,000
homes to be evacuated,
106
00:05:36,292 --> 00:05:38,791
many of them
eventually destroyed.
107
00:05:43,167 --> 00:05:44,999
Two days after people,
108
00:05:45,000 --> 00:05:48,082
there's no one in Palo
Verde's controller room,
109
00:05:48,083 --> 00:05:50,125
no technicians keeping watch,
110
00:05:50,250 --> 00:05:54,667
and the plant's automated
systems rely on human oversight.
111
00:05:54,792 --> 00:05:57,833
The system is constantly
monitored by operators
112
00:05:58,000 --> 00:06:01,750
who can make adjustments
and respond to alerts.
113
00:06:01,875 --> 00:06:05,458
If the system senses that
nobody is responding to it,
114
00:06:05,625 --> 00:06:08,000
it immediately
triggers a shutdown.
115
00:06:09,417 --> 00:06:11,750
Before a meltdown happens,
a mechanism is triggered.
116
00:06:11,875 --> 00:06:15,417
That drops a control
rod into the core,
117
00:06:15,542 --> 00:06:19,167
halting, or at least
dramatically slowing,
118
00:06:19,333 --> 00:06:20,333
the nuclear reaction.
119
00:06:20,500 --> 00:06:22,542
As it
was designed to do,
120
00:06:22,708 --> 00:06:25,500
the system shuts
the reactors down.
121
00:06:25,667 --> 00:06:29,333
But even then, the
danger doesn't die.
122
00:06:29,458 --> 00:06:33,542
Spent fuel rods still
radiate an unholy heat
123
00:06:33,708 --> 00:06:37,624
powerful enough to melt
through steel, concrete,
124
00:06:37,625 --> 00:06:40,667
and anything that
stands in its way.
125
00:06:42,417 --> 00:06:43,750
Used-up fuel rods
126
00:06:43,875 --> 00:06:47,500
stay dangerously hot and
radioactive for years.
127
00:06:47,625 --> 00:06:50,458
That's why they're stored
under water in cooling pools
128
00:06:50,583 --> 00:06:53,583
to prevent them from
overheating or catching fire.
129
00:06:53,708 --> 00:06:55,125
The cooling pools
130
00:06:55,292 --> 00:06:57,500
are the plant's last
line of defense.
131
00:06:57,667 --> 00:07:00,583
But to keep the simmering
rods from overheating,
132
00:07:00,708 --> 00:07:03,333
pumps have to constantly
move cold water in
133
00:07:03,500 --> 00:07:05,042
and hot water out.
134
00:07:06,542 --> 00:07:08,750
The cooling pump system
would still be working
135
00:07:08,917 --> 00:07:11,083
because there are
backup generators
136
00:07:11,208 --> 00:07:12,832
that work on diesel fuel.
137
00:07:12,833 --> 00:07:15,291
In a world
without people,
138
00:07:15,292 --> 00:07:17,999
there's no one to
maintain the generators,
139
00:07:18,000 --> 00:07:20,500
no one to refill their tanks.
140
00:07:20,667 --> 00:07:24,333
What will happen when the power
eventually grinds to a halt?
141
00:07:29,292 --> 00:07:32,124
Far from the sprawling
desert suburbs
142
00:07:32,125 --> 00:07:35,708
lies one of the condominium
capitals of the country:
143
00:07:35,875 --> 00:07:37,457
Miami.
144
00:07:37,458 --> 00:07:40,083
Once, more than
half a million units
145
00:07:40,208 --> 00:07:42,291
were alive with laughter,
146
00:07:42,292 --> 00:07:45,457
the sound of shared
meals and music.
147
00:07:45,458 --> 00:07:49,583
Now, all that remains
are empty tables,
148
00:07:49,750 --> 00:07:53,917
echoes of people who will
never come home again.
149
00:07:54,083 --> 00:07:58,167
Almost 1/3 of Miami's
housing stock is condominiums.
150
00:07:58,292 --> 00:07:59,333
That's the highest percentage
151
00:07:59,500 --> 00:08:01,250
of any major city in
the United States,
152
00:08:01,458 --> 00:08:03,333
which goes to show
that the ideal
153
00:08:03,542 --> 00:08:05,500
of the white picket
fence in the suburbs
154
00:08:05,667 --> 00:08:09,000
isn't always what the
American dream looks like.
155
00:08:14,292 --> 00:08:16,499
One week after people,
156
00:08:16,500 --> 00:08:19,791
something has been
hiding in plain sight,
157
00:08:19,792 --> 00:08:24,958
lingering in the air,
and already hard at work.
158
00:08:26,958 --> 00:08:30,208
Miami has what's called
a tropical monsoon climate.
159
00:08:30,333 --> 00:08:33,042
Basically, because of the
surrounding warm ocean,
160
00:08:33,167 --> 00:08:36,417
Biscayne Bay, and
regular afternoon rain,
161
00:08:36,583 --> 00:08:38,999
it's humid all day, every day.
162
00:08:40,417 --> 00:08:42,292
Most of the older
condos in Miami Beach
163
00:08:42,500 --> 00:08:44,917
were built out of
porous materials.
164
00:08:45,042 --> 00:08:47,208
Not only would
humidity and moisture
165
00:08:47,333 --> 00:08:48,833
get into the buildings quickly,
166
00:08:48,958 --> 00:08:51,542
they would start to do
damage almost immediately.
167
00:08:53,583 --> 00:08:56,666
Miami's power
grid has been down for days
168
00:08:56,667 --> 00:09:00,250
and every condo in the city
is sizzling in the heat.
169
00:09:02,042 --> 00:09:03,957
Without ventilation
and air conditioning,
170
00:09:03,958 --> 00:09:06,875
the temperature could
spike up to 100 degrees.
171
00:09:07,000 --> 00:09:09,667
Within a few days,
food would rot,
172
00:09:09,875 --> 00:09:12,124
condensation would form
on counters and walls,
173
00:09:12,125 --> 00:09:15,333
and all that heat and humidity
would start to warp the wood.
174
00:09:15,458 --> 00:09:18,083
The scent
of rot fills the air;
175
00:09:18,208 --> 00:09:22,833
decay spreads like fog through
condos across the city.
176
00:09:22,958 --> 00:09:27,375
It's an unspoken invitation
to nature's perfect pest.
177
00:09:29,875 --> 00:09:31,667
Cockroaches
would waste no time
178
00:09:31,792 --> 00:09:34,917
finding all the little cracks
and crevices to get inside.
179
00:09:36,625 --> 00:09:39,875
Roaches would love to eat
exactly the kind of trash
180
00:09:40,000 --> 00:09:42,792
that would be festering
in the heat and humidity:
181
00:09:43,875 --> 00:09:46,291
moldy cheese, spoiled meat,
182
00:09:46,292 --> 00:09:49,917
they even like to drink the
garbage juice as it decomposes.
183
00:09:51,875 --> 00:09:53,542
Once they've gotten
through all the trash
184
00:09:53,667 --> 00:09:55,750
and the rotten food left behind,
185
00:09:55,875 --> 00:09:58,708
they'll move on to other
things like book bindings,
186
00:09:58,875 --> 00:10:02,625
old mail, the carcasses
of dead house pets,
187
00:10:02,792 --> 00:10:07,083
even things like old skin
cells, hair, and nail clippings.
188
00:10:07,208 --> 00:10:10,083
Americans actually used
to spend millions of dollars
189
00:10:10,208 --> 00:10:11,333
on exterminators,
190
00:10:11,458 --> 00:10:14,000
trying to keep
cockroaches in check,
191
00:10:14,208 --> 00:10:17,832
but those defense
systems are gone.
192
00:10:17,833 --> 00:10:21,333
After people, there's
no one to lay down traps,
193
00:10:21,458 --> 00:10:23,917
no one to spray pesticide.
194
00:10:24,042 --> 00:10:28,250
And cockroaches aren't just
devouring everything in sight,
195
00:10:28,375 --> 00:10:30,167
they're multiplying.
196
00:10:30,333 --> 00:10:33,624
Cockroaches love the
heat and the humidity,
197
00:10:33,625 --> 00:10:36,167
especially the American
and Asian species
198
00:10:36,292 --> 00:10:38,458
that you find in Miami.
199
00:10:38,583 --> 00:10:39,958
Cockroaches are cold-blooded.
200
00:10:40,083 --> 00:10:42,333
Warmer temperatures
give them more energy.
201
00:10:42,458 --> 00:10:44,583
That means they
fly more, eat more,
202
00:10:44,750 --> 00:10:48,167
and make more roaches more.
203
00:10:51,250 --> 00:10:54,666
Cockroaches are
disgusting nightmare fuel.
204
00:10:54,667 --> 00:10:58,291
A single pair of can produce
up to 400,000 descendants
205
00:10:58,292 --> 00:10:59,750
in a single year,
206
00:10:59,875 --> 00:11:04,000
and it only takes babies
about 35 days to mature.
207
00:11:04,208 --> 00:11:05,333
Without pest control,
208
00:11:05,458 --> 00:11:09,042
just a few cockroaches can
become a full-on infestation
209
00:11:09,208 --> 00:11:11,208
in no time at all.
210
00:11:11,375 --> 00:11:13,167
Inside
abandoned homes,
211
00:11:13,292 --> 00:11:16,583
the cockroaches are sheltered
from natural predators,
212
00:11:16,708 --> 00:11:18,625
and they're spreading.
213
00:11:18,750 --> 00:11:20,500
Cockroaches have no problem
214
00:11:20,708 --> 00:11:22,916
traveling between units
with shared walls.
215
00:11:22,917 --> 00:11:24,667
That's because they can compress
216
00:11:24,833 --> 00:11:26,625
their flexible exoskeletons down
217
00:11:26,792 --> 00:11:28,333
to at least half
their normal size,
218
00:11:28,542 --> 00:11:30,000
and they splay their legs out,
219
00:11:30,125 --> 00:11:33,208
making them able to go through
even the tiniest of cracks
220
00:11:33,333 --> 00:11:34,375
without slowing down.
221
00:11:35,333 --> 00:11:38,208
Once home
to a family of four,
222
00:11:38,375 --> 00:11:42,125
this condo is now a
kingdom of cockroaches.
223
00:11:42,250 --> 00:11:44,750
They're burrowed
beneath the floorboards,
224
00:11:44,875 --> 00:11:47,250
pulsing behind the walls.
225
00:11:47,375 --> 00:11:52,000
With the power off, they
ride and feast in the dark.
226
00:11:52,208 --> 00:11:57,042
But one thing still
glows, small, forgotten,
227
00:11:57,208 --> 00:11:58,957
a pilot light burns,
228
00:11:58,958 --> 00:12:03,167
waiting to turn
infestation into ignition.
229
00:12:08,750 --> 00:12:09,957
The Arizona suburbs
230
00:12:09,958 --> 00:12:12,375
were once home to
millions of people.
231
00:12:12,500 --> 00:12:16,458
Now, the streets are silent,
every house abandoned.
232
00:12:16,583 --> 00:12:19,957
And just weeks after people
at the nuclear power plant
233
00:12:19,958 --> 00:12:22,667
that used to power
these neighborhoods,
234
00:12:22,833 --> 00:12:23,958
backup generators
235
00:12:24,333 --> 00:12:27,708
are now the only thing keeping
emergency pumps pumping
236
00:12:27,833 --> 00:12:30,375
and spent fuel rods
from melting down.
237
00:12:31,875 --> 00:12:34,750
There's enough diesel on
hand to keep the pumps running,
238
00:12:34,917 --> 00:12:38,000
but only if there's someone
there to refill them.
239
00:12:38,167 --> 00:12:40,291
With no one
to refuel their tanks,
240
00:12:40,292 --> 00:12:44,333
the generators choke on
the last fumes of diesel.
241
00:12:44,542 --> 00:12:46,583
The pumps sputter and die.
242
00:12:46,750 --> 00:12:49,667
Slumber and fuel
rods begin to stir
243
00:12:49,792 --> 00:12:53,208
not to supply power to
the surrounding suburbs,
244
00:12:53,375 --> 00:12:55,750
but to bring annihilation.
245
00:13:00,542 --> 00:13:03,583
The water would start to
evaporate slowly at first
246
00:13:03,708 --> 00:13:04,583
and then faster.
247
00:13:06,708 --> 00:13:09,417
The water in the
cooling pools boils off,
248
00:13:09,542 --> 00:13:12,333
exposing the fuel rods to air.
249
00:13:12,458 --> 00:13:15,291
To put it mildly, this is bad.
250
00:13:15,292 --> 00:13:17,624
The fuel rods are
coated in zirconium,
251
00:13:17,625 --> 00:13:19,000
which is stable under water,
252
00:13:19,167 --> 00:13:21,958
but is dangerous when
it's exposed to the air.
253
00:13:22,083 --> 00:13:24,917
Because once zirconium
is out of the water,
254
00:13:25,042 --> 00:13:26,833
it can react
chemically with steam,
255
00:13:27,000 --> 00:13:28,500
releasing hydrogen gas.
256
00:13:28,708 --> 00:13:31,875
And hydrogen gas is explosive.
257
00:13:32,042 --> 00:13:33,042
Like,
258
00:13:33,375 --> 00:13:36,000
hydrogen gas is what caused the
Hindenburg to explode.
259
00:13:36,167 --> 00:13:39,708
Hydrogen gas hangs
in the air, growing thick,
260
00:13:39,875 --> 00:13:41,958
until it meets a spark.
261
00:13:42,083 --> 00:13:44,875
And all at once, it explodes.
262
00:13:49,500 --> 00:13:52,750
This isn't a nuclear
explosion, it's a chemical one,
263
00:13:52,875 --> 00:13:54,500
but the damage is catastrophic.
264
00:13:58,333 --> 00:14:00,875
Once a fire takes hold
in a spent fuel pool,
265
00:14:01,000 --> 00:14:03,167
it's nearly impossible to stop.
266
00:14:03,333 --> 00:14:06,750
The smoke can carry radioactive
material hundreds of miles.
267
00:14:09,333 --> 00:14:12,458
The power plant is
being consumed from within;
268
00:14:12,625 --> 00:14:16,999
radiation spilling out of
every new breach of its walls.
269
00:14:17,000 --> 00:14:20,917
The toxic clouds spit out by
the fire rises on the wind,
270
00:14:21,042 --> 00:14:23,292
moving toward the
nearby suburbs,
271
00:14:23,458 --> 00:14:25,250
killing anything living,
272
00:14:25,375 --> 00:14:27,875
blanketing block
after block of houses
273
00:14:28,042 --> 00:14:31,374
in corrosive isotopes
and gamma radiation.
274
00:14:31,375 --> 00:14:35,042
How long before the
homes of Mesa, Arizona
275
00:14:35,167 --> 00:14:37,208
are nothing but dust?
276
00:14:40,708 --> 00:14:42,917
In rural Pennsylvania,
277
00:14:43,042 --> 00:14:46,000
there are no pickup trucks
traveling the dirt roads,
278
00:14:46,208 --> 00:14:48,708
no shoppers at
the general store.
279
00:14:48,833 --> 00:14:50,250
On a small farm,
280
00:14:50,375 --> 00:14:53,833
there's a homestead that
stood for nearly 200 years,
281
00:14:53,958 --> 00:14:57,458
but now, no one calls it home.
282
00:14:57,583 --> 00:15:00,000
The key to making
these homes long-lasting
283
00:15:00,167 --> 00:15:02,124
is using old growth lumber,
284
00:15:02,125 --> 00:15:04,375
which comes from
trees grown naturally
285
00:15:04,500 --> 00:15:07,500
for hundreds or even
thousands of years.
286
00:15:07,625 --> 00:15:11,542
The natural growth process
makes old growth wood sturdy
287
00:15:11,667 --> 00:15:13,208
and resistant to rot.
288
00:15:13,375 --> 00:15:15,499
Not only were the
houses meant to last,
289
00:15:15,500 --> 00:15:16,875
but the homesteads themselves
290
00:15:17,042 --> 00:15:18,875
were meant to be
self-sustaining.
291
00:15:19,042 --> 00:15:21,000
You'll find pens
for livestock,
292
00:15:21,125 --> 00:15:23,042
wells to access fresh water,
293
00:15:23,167 --> 00:15:25,167
and root cellars to
store vegetables.
294
00:15:25,333 --> 00:15:26,791
And in the right conditions,
295
00:15:26,792 --> 00:15:31,667
foods like potatoes, squash,
and pears can last for months.
296
00:15:33,000 --> 00:15:35,958
This homestead
has housed and fed families
297
00:15:36,083 --> 00:15:39,000
since decades before
the Civil War.
298
00:15:39,167 --> 00:15:43,874
But just one week after people,
some crops are withering,
299
00:15:43,875 --> 00:15:45,957
others are growing unchecked.
300
00:15:49,708 --> 00:15:51,958
And it ends in paddocks,
301
00:15:52,125 --> 00:15:56,167
livestock is
neglected and hungry.
302
00:15:56,333 --> 00:15:59,250
A pig eats about 4% of
its body weight a day,
303
00:15:59,417 --> 00:16:02,458
and they can weigh as
much as 800 pounds.
304
00:16:02,583 --> 00:16:03,833
So basically,
305
00:16:04,042 --> 00:16:07,042
a pig would need to eat
a large bag of dog food,
306
00:16:07,208 --> 00:16:11,333
enough to last a big dog about
a month every single day.
307
00:16:12,708 --> 00:16:14,167
Pigs aren't picky eaters.
308
00:16:14,333 --> 00:16:18,917
They'll eat just about anything:
roots, bugs, other animals.
309
00:16:19,083 --> 00:16:22,791
They've even been known to
eat an entire human corpse,
310
00:16:22,792 --> 00:16:25,208
bones and all, in
less than eight hours.
311
00:16:28,667 --> 00:16:32,000
The pigs have devoured
everything in their pen,
312
00:16:32,125 --> 00:16:35,042
including the wooden
fences themselves,
313
00:16:35,208 --> 00:16:38,208
relics of farmers
now gone forever.
314
00:16:38,375 --> 00:16:41,542
Pigs are among the top
five smartest animals around.
315
00:16:41,708 --> 00:16:43,083
Some studies suggest
316
00:16:43,250 --> 00:16:45,917
that they're about as smart
as a three-year-old human.
317
00:16:47,333 --> 00:16:48,917
Between their size
and their smarts,
318
00:16:49,042 --> 00:16:49,667
it wouldn't take much for them
319
00:16:49,958 --> 00:16:51,000
to find a way out of their pens.
320
00:16:51,167 --> 00:16:52,375
They can just dig up fencing
321
00:16:52,500 --> 00:16:54,667
and break down just about
anything in their way.
322
00:16:56,083 --> 00:16:57,624
Two
weeks after people,
323
00:16:57,625 --> 00:17:01,167
the pigs have eaten through
crops like a disease,
324
00:17:01,292 --> 00:17:03,917
but their hunger is insatiable.
325
00:17:04,042 --> 00:17:07,167
And now, they have a
craving for fresh meat.
326
00:17:12,542 --> 00:17:13,875
Chickens have
been domesticated
327
00:17:14,042 --> 00:17:15,541
for more than 10,000 years,
328
00:17:15,542 --> 00:17:18,500
so one would think that
without people around,
329
00:17:18,625 --> 00:17:19,917
they'd be helpless.
330
00:17:20,083 --> 00:17:23,833
But remarkably, without
people, they do quite well.
331
00:17:25,917 --> 00:17:26,875
With no one to feed them,
332
00:17:27,208 --> 00:17:29,375
they're gonna revert to
their primitive instincts,
333
00:17:29,542 --> 00:17:33,500
pecking for ants, and grubs,
and any seeds they can find.
334
00:17:33,708 --> 00:17:35,917
Even without human
hands to care for them,
335
00:17:36,083 --> 00:17:39,167
the chickens are
plump and healthy.
336
00:17:39,333 --> 00:17:41,625
They're also locked
in their coop,
337
00:17:41,792 --> 00:17:43,957
a perfect target for pigs,
338
00:17:43,958 --> 00:17:45,957
ravenous and on the prowl.
339
00:17:52,375 --> 00:17:56,291
Over 1,000 miles to the
south, months after people,
340
00:17:56,292 --> 00:17:59,833
Miami's abandoned condominiums
are being remodeled,
341
00:17:59,958 --> 00:18:01,833
with new carpets and wallpaper
342
00:18:01,958 --> 00:18:04,167
made of wriggling cockroaches,
343
00:18:04,292 --> 00:18:06,417
gnawing through
everything they touch,
344
00:18:06,542 --> 00:18:10,291
burrowing into every
crack and crevice.
345
00:18:10,292 --> 00:18:11,457
And here's where it gets ugly.
346
00:18:11,458 --> 00:18:14,166
Cockroaches, they
leave their droppings,
347
00:18:14,167 --> 00:18:16,124
molted shells, and
even their bodies.
348
00:18:17,458 --> 00:18:18,500
The power's out,
349
00:18:18,875 --> 00:18:22,000
but some old gas stoves still
have a flickering flame.
350
00:18:22,167 --> 00:18:23,583
That's the pilot light,
351
00:18:23,708 --> 00:18:26,083
which doesn't need
electricity to burn.
352
00:18:26,208 --> 00:18:29,167
It's fed by a tiny,
steady stream of gas
353
00:18:29,333 --> 00:18:33,250
designed to keep flowing
for months or even years.
354
00:18:33,417 --> 00:18:35,583
The mess builds up
around a pilot assembly,
355
00:18:35,708 --> 00:18:38,333
jamming the valve that
controls the gas flow.
356
00:18:38,458 --> 00:18:41,000
The result is a
stuck open gas line.
357
00:18:41,208 --> 00:18:44,332
Now you've got gas spreading
throughout a condo unit.
358
00:18:44,333 --> 00:18:46,332
It's going under the doors,
359
00:18:46,333 --> 00:18:49,624
out into the hallway,
into other units.
360
00:18:51,000 --> 00:18:52,542
In the time of people,
361
00:18:52,667 --> 00:18:55,000
simple maintenance
and routine inspection
362
00:18:55,167 --> 00:18:57,000
would eliminate the threat.
363
00:18:57,167 --> 00:19:00,083
Now, gas is seeping
through condo units
364
00:19:00,250 --> 00:19:02,625
like poison through veins.
365
00:19:02,792 --> 00:19:06,042
What will happen when it
finally touches the pilot light
366
00:19:06,208 --> 00:19:07,708
flickering in the dark?
367
00:19:15,708 --> 00:19:20,667
Two months after
people, Miami is a ghost town.
368
00:19:21,958 --> 00:19:24,833
A fire caused by a gas leak
and a flickering pilot light
369
00:19:24,958 --> 00:19:26,833
has engulfed a condo,
370
00:19:27,000 --> 00:19:30,332
threatening all the units
people once called home.
371
00:19:31,625 --> 00:19:33,957
Remember, in a
high rise like this,
372
00:19:33,958 --> 00:19:35,083
everything's connected.
373
00:19:35,208 --> 00:19:37,250
That means shared walls,
374
00:19:37,375 --> 00:19:39,542
shared ventilation,
shared gas lines.
375
00:19:41,042 --> 00:19:44,792
So now that initial explosion
cracks open even more lines,
376
00:19:44,917 --> 00:19:48,125
releasing even more gas,
it's a chain reaction.
377
00:19:48,250 --> 00:19:49,833
Boom, boom, boom.
378
00:19:53,125 --> 00:19:55,292
Always become fire tunnels.
379
00:19:55,417 --> 00:19:58,666
In minutes, a big part of
the building is in flames.
380
00:19:58,667 --> 00:20:01,542
And just like that,
it's a flowing inferno.
381
00:20:02,375 --> 00:20:03,667
Just as the flames
382
00:20:03,833 --> 00:20:07,375
threaten to leap across
blocks and engulf the city,
383
00:20:07,500 --> 00:20:09,708
something shifts in the air,
384
00:20:09,833 --> 00:20:13,583
and the very humidity
that helped cause the fire
385
00:20:13,708 --> 00:20:17,167
gives rise to the only
thing that can stop it.
386
00:20:21,625 --> 00:20:24,542
In the summer, Miami
often gets heavy rain,
387
00:20:24,667 --> 00:20:28,417
often in the form of brief,
but intense, thunderstorms.
388
00:20:28,542 --> 00:20:31,042
A single storm can unleash
two to three inches of rain
389
00:20:31,167 --> 00:20:32,208
in mere minutes.
390
00:20:33,583 --> 00:20:34,917
The heavens rain down
391
00:20:35,083 --> 00:20:37,208
what looks like salvation,
392
00:20:37,417 --> 00:20:40,458
but it's a wolf hidden
in sheep's clothing,
393
00:20:40,583 --> 00:20:43,666
eager to infiltrate and attack.
394
00:20:45,250 --> 00:20:47,667
Now imagine that
kind of downpour
395
00:20:47,792 --> 00:20:51,500
slamming into a building already
cracked open and crumbling.
396
00:20:51,625 --> 00:20:54,333
Torrents of rain crashed
through broken windows,
397
00:20:54,458 --> 00:20:56,875
soaking the carpet
walls and wiring.
398
00:20:58,500 --> 00:21:00,500
The rain pours
through every crack,
399
00:21:00,708 --> 00:21:04,000
soaking drywall,
pulling on floors.
400
00:21:04,167 --> 00:21:06,208
The rain puts out the fire,
401
00:21:06,333 --> 00:21:08,917
but brings its own
kind of destruction.
402
00:21:10,458 --> 00:21:12,499
Just
months after people,
403
00:21:12,500 --> 00:21:14,625
condo buildings all over Florida
404
00:21:14,750 --> 00:21:19,042
are cracking, leaking,
bending, and buckling.
405
00:21:21,542 --> 00:21:24,917
But there's one building
that towers above the rest,
406
00:21:25,042 --> 00:21:26,917
resolute and unbowed.
407
00:21:28,208 --> 00:21:32,083
It's 84 luxury condos'
indoor infinity pool
408
00:21:32,208 --> 00:21:34,167
and private helipad,
409
00:21:34,292 --> 00:21:36,958
where once home to
the richest elites,
410
00:21:37,083 --> 00:21:40,000
now it lies as silent as a tomb,
411
00:21:41,458 --> 00:21:45,832
a monument to the wealthiest
members of a dead civilization.
412
00:21:48,375 --> 00:21:51,124
One Thousand Museum was
designed more like a yacht
413
00:21:51,125 --> 00:21:52,542
than a condo,
414
00:21:52,833 --> 00:21:57,542
using marine-grade wood, stone,
glass, and minimal carpet.
415
00:21:58,542 --> 00:22:00,083
Plus, the triple-sealed
hurricane windows
416
00:22:00,208 --> 00:22:01,500
and thermal insulation
417
00:22:01,667 --> 00:22:03,458
will prevent it from
getting too hot in there.
418
00:22:03,583 --> 00:22:05,624
It might get a
little uncomfortable,
419
00:22:05,625 --> 00:22:07,666
but its materials
were handpicked
420
00:22:07,667 --> 00:22:09,250
to deal with those conditions.
421
00:22:10,542 --> 00:22:12,542
While most
of Miami festers,
422
00:22:12,667 --> 00:22:16,083
this residential
tower refuses to rot.
423
00:22:16,208 --> 00:22:18,625
But father time is patient.
424
00:22:18,792 --> 00:22:23,249
How long before this
tower succumbs as well?
425
00:22:30,125 --> 00:22:32,667
Six months after people,
426
00:22:32,833 --> 00:22:36,875
at a farm that was once home
to a hardworking family,
427
00:22:37,042 --> 00:22:38,791
the ravenous grunting of pigs
428
00:22:38,792 --> 00:22:42,000
fills the air outside
the chicken coop.
429
00:22:42,125 --> 00:22:44,499
No longer fed by humans,
430
00:22:44,500 --> 00:22:47,375
the pigs are starving
and aggressive,
431
00:22:47,542 --> 00:22:50,083
and fresh poultry
is on the menu.
432
00:22:52,625 --> 00:22:55,083
Chicken coops are designed
to keep out coyotes,
433
00:22:55,208 --> 00:22:56,542
raccoons, and other birds.
434
00:22:56,708 --> 00:22:59,792
Your garden-variety,
lightweight predator.
435
00:22:59,917 --> 00:23:01,292
Pigs love to root,
436
00:23:01,417 --> 00:23:03,083
and they can easily
get their snouts
437
00:23:03,208 --> 00:23:05,332
two to three feet
deep under the soil.
438
00:23:05,333 --> 00:23:06,375
And chicken coop foundations
439
00:23:06,750 --> 00:23:09,625
are typically only a foot
to a foot and a half deep,
440
00:23:09,833 --> 00:23:13,292
so pigs would have no trouble
working their way inside.
441
00:23:13,458 --> 00:23:14,667
Once they're under
the foundations,
442
00:23:14,792 --> 00:23:16,583
there is nothing
to stop these pigs
443
00:23:16,708 --> 00:23:19,167
from entering the coop
and wreaking havoc.
444
00:23:20,833 --> 00:23:23,042
They would eat what's
left to the chicken feed,
445
00:23:23,208 --> 00:23:24,500
they would eat any
eggs in the coop,
446
00:23:24,625 --> 00:23:26,833
and then they would
eat the chickens.
447
00:23:29,333 --> 00:23:30,457
The most
accessible food
448
00:23:30,458 --> 00:23:32,458
has now been gobbled up,
449
00:23:32,583 --> 00:23:35,208
and the once-docile pigs
turn their attention
450
00:23:35,333 --> 00:23:37,791
to the farmhouse itself.
451
00:23:37,792 --> 00:23:42,333
But while the home has barely
changed in hundreds of years,
452
00:23:42,458 --> 00:23:45,708
the pigs are quickly
transforming,
453
00:23:45,833 --> 00:23:49,958
shedding domestication like
a snake sloughs off its skin.
454
00:23:51,208 --> 00:23:52,500
It's pretty incredible
455
00:23:52,625 --> 00:23:54,917
how quickly domesticated
pigs go feral
456
00:23:55,042 --> 00:23:58,250
and start to resemble the wild
boars that they descend from.
457
00:23:58,375 --> 00:24:00,292
This can start to
happen within weeks.
458
00:24:00,417 --> 00:24:03,167
And by the time a
year has gone by,
459
00:24:03,292 --> 00:24:04,917
they become almost
unrecognizable.
460
00:24:06,375 --> 00:24:09,666
Their hair starts to grow
coarser and darker in color,
461
00:24:09,667 --> 00:24:12,458
the males start to
grow prominent tusks.
462
00:24:12,583 --> 00:24:14,458
They get leaner
and more muscular
463
00:24:14,583 --> 00:24:16,791
with increased
foraging and rooting.
464
00:24:16,792 --> 00:24:19,457
Their behavior starts
to change as well.
465
00:24:19,458 --> 00:24:20,667
As they get wilder,
466
00:24:20,792 --> 00:24:22,958
the pigs' snouts elongate a bit
467
00:24:23,083 --> 00:24:25,542
and their sense of
smell gets even better,
468
00:24:25,708 --> 00:24:27,291
which is saying something
469
00:24:27,292 --> 00:24:29,792
because even domesticated pigs
470
00:24:29,917 --> 00:24:32,750
can smell food buried
25 feet underground.
471
00:24:32,875 --> 00:24:36,583
As they go feral, pigs
start to become nocturnal.
472
00:24:37,875 --> 00:24:40,833
And feral pigs are known to
become highly aggressive.
473
00:24:42,167 --> 00:24:45,542
This is no
longer a sounder of swine.
474
00:24:45,667 --> 00:24:47,832
It's a beastly-wrecking crew.
475
00:24:47,833 --> 00:24:50,000
Food inside the old farmhouse
476
00:24:50,125 --> 00:24:53,542
is beckoning to them
like a siren song.
477
00:24:53,708 --> 00:24:56,666
Can this sturdy home
keep the hogs at bay,
478
00:24:56,667 --> 00:25:00,207
or will they bring
it all crashing down?
479
00:25:08,333 --> 00:25:10,750
Six
months after people,
480
00:25:10,875 --> 00:25:14,875
this small family
farmstead is in disarray.
481
00:25:15,042 --> 00:25:18,500
Once neat rows of crops have
been ripped from the soil
482
00:25:18,625 --> 00:25:21,958
and devoured by
ravenous feral pigs.
483
00:25:22,083 --> 00:25:25,208
The farmhouse has been
home to generations
484
00:25:25,333 --> 00:25:29,583
standing strong through 40
presidents, countless blizzards,
485
00:25:29,708 --> 00:25:31,750
and two World Wars.
486
00:25:31,875 --> 00:25:35,083
Now, hooves scrape the doors,
487
00:25:35,292 --> 00:25:37,708
snouts root at foundations,
488
00:25:37,875 --> 00:25:41,333
the hungry hogs are
desperate to get inside.
489
00:25:43,125 --> 00:25:44,667
The pigs would be lured
490
00:25:44,792 --> 00:25:47,542
by the smells coming from
inside the farmhouse.
491
00:25:47,708 --> 00:25:50,208
If they get hungry
and desperate enough,
492
00:25:50,375 --> 00:25:53,042
they will try anything
to get inside.
493
00:25:54,792 --> 00:25:57,499
They may look like
lumbering wrecking balls,
494
00:25:57,500 --> 00:26:00,417
but pigs are surprisingly fast.
495
00:26:00,542 --> 00:26:03,458
They can run up to
11 miles per hour.
496
00:26:03,583 --> 00:26:06,417
So, if one takes aim at
the front door of a house,
497
00:26:06,625 --> 00:26:08,749
it's like launching
a bowling ball at it.
498
00:26:11,667 --> 00:26:14,292
The pigs
break in like thieves,
499
00:26:14,458 --> 00:26:16,666
but they don't
bother with stealth.
500
00:26:16,667 --> 00:26:20,666
They're brazen, remorseless,
and destructive.
501
00:26:20,667 --> 00:26:24,332
Pigs bite with enough force
to break some human bones,
502
00:26:24,333 --> 00:26:27,750
so it'd be easy work to tear
off cupboard or closet doors
503
00:26:27,875 --> 00:26:30,208
to get at what's stored inside.
504
00:26:30,375 --> 00:26:34,208
These pigs would devour any
dried goods left behind:
505
00:26:34,375 --> 00:26:36,792
flour, oat, cereals,
you name it.
506
00:26:36,917 --> 00:26:39,708
And if they were able to
crack open that fridge door,
507
00:26:39,833 --> 00:26:41,500
I'm sure they would
be happy to eat
508
00:26:41,667 --> 00:26:46,250
whatever year-old biohazard
they would find inside.
509
00:26:46,375 --> 00:26:48,542
If anything kept in
jars fell off the shelves,
510
00:26:48,708 --> 00:26:49,708
they'd eat it,
511
00:26:50,083 --> 00:26:52,167
probably sucking up some
broken glass at the same time.
512
00:26:52,375 --> 00:26:54,167
And I don't know if they
could bite open canned food,
513
00:26:54,292 --> 00:26:55,833
but they would sure as hell try.
514
00:26:58,083 --> 00:26:59,542
And let's just be
clear about one thing.
515
00:26:59,667 --> 00:27:01,917
Pigs are not polite.
516
00:27:02,042 --> 00:27:03,292
They're pigs.
517
00:27:03,417 --> 00:27:05,667
Even the trace smell of old food
518
00:27:05,833 --> 00:27:07,457
is gonna drive
them into a frenzy.
519
00:27:07,458 --> 00:27:10,500
They will destroy furniture,
they will tear up floorboards,
520
00:27:10,625 --> 00:27:11,917
they will smash
holes in the wall.
521
00:27:12,042 --> 00:27:14,333
If they find any
possible weak spot,
522
00:27:14,458 --> 00:27:16,208
like water damage
or rotten siding,
523
00:27:16,375 --> 00:27:19,832
they're just gonna plow
right through that.
524
00:27:19,833 --> 00:27:23,500
Once home to the
family who fed and kept them,
525
00:27:23,708 --> 00:27:26,167
the feral pigs have
turned this farmhouse
526
00:27:26,333 --> 00:27:28,208
into a splintered husk.
527
00:27:28,375 --> 00:27:33,167
Now, they leave it behind to
maraud through the countryside.
528
00:27:38,500 --> 00:27:40,250
In Mesa, Arizona,
529
00:27:40,375 --> 00:27:43,750
the biggest suburb in
the country is quiet,
530
00:27:43,875 --> 00:27:46,542
but looks almost unchanged.
531
00:27:46,667 --> 00:27:49,708
Cars are still
parked in driveways,
532
00:27:49,833 --> 00:27:53,042
water ripples in backyard pools.
533
00:27:53,208 --> 00:27:57,249
But just like in the Chernobyl
and Fukushima disasters,
534
00:27:57,250 --> 00:28:01,999
an invisible toxic wind from
the Palo Verde nuclear meltdown
535
00:28:02,000 --> 00:28:06,167
has blown over 100
miles from the plant.
536
00:28:06,292 --> 00:28:08,500
It's touched every surface,
537
00:28:08,625 --> 00:28:11,833
found every crack
and open window,
538
00:28:12,000 --> 00:28:15,250
sparing nothing in this
once-peaceful suburb.
539
00:28:16,500 --> 00:28:18,875
These homes may look
picture perfect from the curb,
540
00:28:19,000 --> 00:28:20,708
but they're actually saturated
541
00:28:20,833 --> 00:28:24,500
with a poison that you
can't see, smell, or escape.
542
00:28:24,667 --> 00:28:27,417
Gamma radiation rains
down on everything
543
00:28:27,542 --> 00:28:32,667
alongside hot isotopes, like
Caesium-137 and Strontium-90,
544
00:28:33,792 --> 00:28:35,708
coating the landscape
and every house in sight.
545
00:28:39,792 --> 00:28:41,208
To give you a sense of scale,
546
00:28:41,333 --> 00:28:44,917
just 1/30 of an ounce
of Caesium-137,
547
00:28:45,042 --> 00:28:47,000
that's a single sunflower seed,
548
00:28:47,125 --> 00:28:51,000
can make a whole square
mile uninhabitable.
549
00:28:51,208 --> 00:28:54,500
Now imagine several
pounds of this stuff.
550
00:28:57,542 --> 00:28:59,583
The fallout seeps into lungs,
551
00:28:59,708 --> 00:29:02,458
wrecking organs
almost immediately.
552
00:29:02,583 --> 00:29:04,500
Within hours, the
smallest animals,
553
00:29:04,667 --> 00:29:07,333
like squirrels and
rabbits, start to drop.
554
00:29:07,458 --> 00:29:10,333
Faster metabolisms mean they
soak up the most the quickest.
555
00:29:10,500 --> 00:29:14,083
By day two, bigger animals,
like deer and coyotes, follow.
556
00:29:15,083 --> 00:29:16,167
Over time,
557
00:29:16,292 --> 00:29:18,999
radiation eats away at
these big suburban homes,
558
00:29:19,000 --> 00:29:21,750
corroding metals,
breaking down plastics,
559
00:29:21,875 --> 00:29:25,332
and the air inside becomes
dangerously radioactive.
560
00:29:27,958 --> 00:29:30,208
The radiation
gnaws at these homes
561
00:29:30,375 --> 00:29:31,875
from the outside,
562
00:29:32,000 --> 00:29:34,708
but deep beneath the
suburban concrete,
563
00:29:34,875 --> 00:29:38,750
something else lurks
hidden from the poison.
564
00:29:38,875 --> 00:29:41,874
They're tiny,
resilient, and hungry.
565
00:29:47,833 --> 00:29:49,458
The biggest
suburb in the world
566
00:29:49,583 --> 00:29:52,208
is being consumed by toxic dust.
567
00:29:52,375 --> 00:29:55,125
But there's something else
crawling and burrowing
568
00:29:55,250 --> 00:29:58,167
beneath the homes that
line these streets,
569
00:29:58,292 --> 00:30:02,125
something that survived the
initial wave of fallout.
570
00:30:02,250 --> 00:30:06,042
Not a cockroach, but
its much smaller cousin.
571
00:30:06,208 --> 00:30:09,291
Termites are extremely
common in Mesa,
572
00:30:09,292 --> 00:30:10,500
and there's a good chance
573
00:30:10,625 --> 00:30:11,792
they would've
survived the radiation
574
00:30:11,917 --> 00:30:13,833
from the Palo Verde plant.
575
00:30:13,958 --> 00:30:16,458
A lot of termites live in
nests several feet underground,
576
00:30:16,625 --> 00:30:18,417
which would provide protection
577
00:30:18,625 --> 00:30:20,417
from that initial
blast of toxicity.
578
00:30:21,667 --> 00:30:23,667
Insects like
cockroaches and termites
579
00:30:23,792 --> 00:30:26,667
are famously resistant
to radiation,
580
00:30:26,833 --> 00:30:29,333
much more so than
humans or other mammals.
581
00:30:29,458 --> 00:30:32,750
Now, organic cells are most
susceptible to radiation
582
00:30:32,875 --> 00:30:34,000
when they're dividing.
583
00:30:34,125 --> 00:30:35,458
And in the human body,
584
00:30:35,625 --> 00:30:39,291
we've got millions of cells
dividing every single day.
585
00:30:39,292 --> 00:30:43,125
But a termite, it only divides
its cells when it's molting.
586
00:30:43,250 --> 00:30:45,708
Couple that with
their extremely rapid
587
00:30:45,875 --> 00:30:47,166
reproductive cycles,
588
00:30:47,167 --> 00:30:49,625
and termites could
very well adapt
589
00:30:49,792 --> 00:30:52,125
to a post-meltdown environment
590
00:30:52,250 --> 00:30:54,167
just like scientists
have witnessed
591
00:30:54,292 --> 00:30:55,625
in the area around Chernobyl.
592
00:30:57,708 --> 00:30:59,833
The termites
bide their time,
593
00:31:00,000 --> 00:31:02,708
then they creep from
their nests like a plague,
594
00:31:02,833 --> 00:31:04,958
swarming toward the
wooden foundations
595
00:31:05,083 --> 00:31:07,458
of Mesa's suburban homes.
596
00:31:07,583 --> 00:31:08,708
Their diets consist mainly
597
00:31:08,833 --> 00:31:10,792
of decaying plant
materials and wood.
598
00:31:10,917 --> 00:31:13,542
And one particular species,
a subterranean termite,
599
00:31:13,667 --> 00:31:16,792
is so ubiquitous it's better
known as the Arizona termite.
600
00:31:16,917 --> 00:31:18,833
It also happens to be
the species of termite
601
00:31:19,000 --> 00:31:21,292
that is most
destructive to homes.
602
00:31:21,417 --> 00:31:25,083
All it takes is a tiny,
tiny crack in the foundations,
603
00:31:25,208 --> 00:31:28,750
less than 1/16 of an
inch, and they're in.
604
00:31:28,917 --> 00:31:31,082
The termites
feast on support beams,
605
00:31:31,083 --> 00:31:33,124
frames, and foundations.
606
00:31:33,125 --> 00:31:36,458
And without human exterminators
to keep them in check,
607
00:31:36,667 --> 00:31:38,957
their population skyrockets.
608
00:31:40,875 --> 00:31:42,000
A termite queen
609
00:31:42,125 --> 00:31:45,792
lays approximately
40,000 eggs per day
610
00:31:45,917 --> 00:31:49,458
and has a life expectancy
of nearly 20 years.
611
00:31:49,583 --> 00:31:53,250
The colony never sleeps
and never stops eating.
612
00:31:53,375 --> 00:31:55,375
The biggest
suburb in the world
613
00:31:55,500 --> 00:31:59,999
is decaying from the outside
and being consumed from within.
614
00:32:00,000 --> 00:32:03,708
How long before there's
nothing left but dust?
615
00:32:11,125 --> 00:32:14,333
20 years after people, in Miami,
616
00:32:14,458 --> 00:32:19,083
One Thousand Museum is now
dirty, aging, worn down.
617
00:32:19,250 --> 00:32:22,833
But the building itself
still stands proud.
618
00:32:23,000 --> 00:32:26,417
A minor hurricane is
roiling the skies offshore,
619
00:32:26,542 --> 00:32:30,000
but this tower, once
home to the ultra-rich,
620
00:32:30,208 --> 00:32:33,833
has a secret weapon humanity
left behind to defend it.
621
00:32:37,583 --> 00:32:41,666
The building is tailor-made
for Miami's harsh environment.
622
00:32:41,667 --> 00:32:46,332
There are 5,000 pieces of
glass-fiber-reinforced concrete
623
00:32:46,333 --> 00:32:49,583
that form kind of an
exoskeleton around the building,
624
00:32:49,708 --> 00:32:52,833
like a giant brace that can
resist the force of wind
625
00:32:53,000 --> 00:32:54,499
during major storms.
626
00:32:55,833 --> 00:32:58,042
One Thousand Museum's
aerodynamic shape
627
00:32:58,167 --> 00:33:00,124
breaks up wind pressure,
628
00:33:00,125 --> 00:33:01,167
the kind of turbulence
629
00:33:01,375 --> 00:33:04,083
that can shake and
rattle a tall building.
630
00:33:04,208 --> 00:33:07,708
And every unit has special
impact-resistant windows
631
00:33:07,833 --> 00:33:11,083
that can withstand something
like a two-by-four hurled at it
632
00:33:11,208 --> 00:33:12,917
at up to 100 miles an hour.
633
00:33:14,667 --> 00:33:17,208
Other condo
buildings aren't so lucky.
634
00:33:17,375 --> 00:33:21,625
They're cracked and sagging;
bones already weakened.
635
00:33:23,208 --> 00:33:26,042
Now there's no seawall,
no flood control,
636
00:33:26,167 --> 00:33:27,833
no first responders,
637
00:33:27,958 --> 00:33:31,125
just a 12-story building
weakened by fire,
638
00:33:31,250 --> 00:33:34,917
teetering on soggy ground
as the storm slams into it.
639
00:33:36,667 --> 00:33:39,291
There will be a
sickening crack from below.
640
00:33:39,292 --> 00:33:40,375
The foundations,
641
00:33:40,583 --> 00:33:43,542
already stressed from
rising groundwater,
642
00:33:43,708 --> 00:33:45,083
start to literally shear off.
643
00:33:45,208 --> 00:33:47,957
Concrete snaps, rebar buckles,
644
00:33:47,958 --> 00:33:50,124
one floor pancakes
onto the next,
645
00:33:50,125 --> 00:33:52,999
and dust and debris shoot
out like a volcanic blast.
646
00:33:54,667 --> 00:33:58,125
12 stories crumple like a
tower of wet playing cards,
647
00:33:58,250 --> 00:34:00,832
each floor crushing the next.
648
00:34:02,250 --> 00:34:04,458
As the condo
crashes into the sea,
649
00:34:04,583 --> 00:34:07,791
there are no people left
to mourn its demise,
650
00:34:07,792 --> 00:34:10,166
no crews to rebuild it,
651
00:34:10,167 --> 00:34:13,833
only a twisted metal
and concrete corpse
652
00:34:14,000 --> 00:34:15,833
reclaimed by the sea.
653
00:34:20,458 --> 00:34:24,292
In Arizona, decades
of radioactive fallout
654
00:34:24,417 --> 00:34:26,917
and the hungry termites
who survived it
655
00:34:27,042 --> 00:34:29,874
have turned the suburb
into the lifeless ruins
656
00:34:29,875 --> 00:34:32,375
of a lost civilization.
657
00:34:32,542 --> 00:34:34,417
They don't devour
large chunks of wood.
658
00:34:34,542 --> 00:34:36,333
Instead, they burrow
tunnels into the wood,
659
00:34:36,500 --> 00:34:38,375
which weakens its
overall structure,
660
00:34:38,500 --> 00:34:41,166
compromising the structural
integrity of the entire home.
661
00:34:42,875 --> 00:34:44,250
One by one,
662
00:34:44,375 --> 00:34:46,292
the once sprawling homes,
663
00:34:46,417 --> 00:34:50,208
prized symbols of a
safe middle class life,
664
00:34:50,333 --> 00:34:53,583
have been reduced
to piles of rubble.
665
00:34:53,750 --> 00:34:56,332
This house has been made
brittle by nuclear fallout.
666
00:34:56,333 --> 00:35:00,042
It's turned to Swiss cheese
by ravenous termites,
667
00:35:00,208 --> 00:35:02,332
and now it's just too fragile
to hold its own weight,
668
00:35:02,333 --> 00:35:05,082
so gravity deals the final blow.
669
00:35:16,875 --> 00:35:19,749
100
years after people,
670
00:35:19,750 --> 00:35:21,792
the houses that were once home
671
00:35:21,958 --> 00:35:24,167
to hundreds of
thousands of people
672
00:35:24,375 --> 00:35:29,333
in the biggest suburb in
America have crumbled into dust,
673
00:35:30,125 --> 00:35:32,458
leaving behind a
barren wasteland.
674
00:35:32,583 --> 00:35:37,625
But even here in the parched
silence and toxic soil,
675
00:35:38,208 --> 00:35:39,333
new life emerges.
676
00:35:39,667 --> 00:35:42,666
Nuclear radiation once
made this place a dead zone.
677
00:35:42,667 --> 00:35:46,042
But now, the worst
isotopes are gone.
678
00:35:46,208 --> 00:35:48,750
Even Caesium-137 has
lost most of its bites.
679
00:35:48,875 --> 00:35:50,208
So if you look carefully,
680
00:35:50,375 --> 00:35:53,250
you might see cracks in the
pavement blooming with weeds,
681
00:35:53,375 --> 00:35:57,000
you might see lizards
scurrying through the ruins.
682
00:35:57,208 --> 00:35:58,917
The streets
are buried under sand,
683
00:35:59,042 --> 00:36:01,833
but mesquite and scrub
are growing again,
684
00:36:02,000 --> 00:36:03,458
tumbleweeds roll
down the highways
685
00:36:03,583 --> 00:36:05,667
like a scene out of
a forgotten western,
686
00:36:05,792 --> 00:36:09,042
except this one's set in a
weird post-apocalyptic suburbia.
687
00:36:10,958 --> 00:36:12,667
In place of manicured lawns,
688
00:36:12,792 --> 00:36:16,167
towering saguaros now
rise like desert kings
689
00:36:16,292 --> 00:36:17,667
staking their claim,
690
00:36:17,833 --> 00:36:20,917
where once porch swings and
garden gnomes used to sit.
691
00:36:22,917 --> 00:36:24,917
After a century without people
692
00:36:25,083 --> 00:36:27,667
under that unforgiving
Arizona sun,
693
00:36:27,792 --> 00:36:31,500
it would almost feel like
humans never existed at all.
694
00:36:34,500 --> 00:36:37,750
150
years after people,
695
00:36:37,917 --> 00:36:39,250
the Pennsylvania farmhouse
696
00:36:39,375 --> 00:36:42,500
that saw generation
after generation thrive
697
00:36:42,667 --> 00:36:46,000
and grow beneath its
roof is now broken;
698
00:36:46,208 --> 00:36:47,833
its bones laid bare.
699
00:36:49,542 --> 00:36:52,292
These old fieldstone
foundations can be very strong,
700
00:36:52,458 --> 00:36:54,458
but time is taking its toll.
701
00:36:55,500 --> 00:36:56,333
For years,
702
00:36:56,500 --> 00:36:58,125
the foundations of the farmhouse
703
00:36:58,292 --> 00:37:00,958
have been sitting wide
open to the elements.
704
00:37:01,125 --> 00:37:03,499
The house is
dismantled bit by bit.
705
00:37:04,792 --> 00:37:06,917
Most of
the home is gone,
706
00:37:07,083 --> 00:37:08,833
but its foundation remains,
707
00:37:08,958 --> 00:37:12,708
anchored in the earth like
the roots of a great tree,
708
00:37:12,875 --> 00:37:16,042
a monument to the farmers
that once worked this land.
709
00:37:18,417 --> 00:37:22,375
In Miami, what was once the
condo capital of the country
710
00:37:22,542 --> 00:37:25,750
has been lashed by
wind, inundated by rain,
711
00:37:25,875 --> 00:37:26,917
and pounded by waves.
712
00:37:28,542 --> 00:37:31,833
What's left in the city
is nearly unrecognizable.
713
00:37:32,000 --> 00:37:35,957
But above the curling,
gripping vines of new growth,
714
00:37:35,958 --> 00:37:39,000
One Thousand Museum
still stands.
715
00:37:40,125 --> 00:37:42,917
One Thousand Museum has
weathered decades of storm,
716
00:37:43,042 --> 00:37:44,500
heat, and rising seas,
717
00:37:44,708 --> 00:37:47,625
thanks to its reinforced
concrete exoskeleton
718
00:37:47,792 --> 00:37:49,250
and cutting-edge design.
719
00:37:49,417 --> 00:37:52,042
It was built to last;
and so far, it has.
720
00:37:52,208 --> 00:37:53,333
But even this,
721
00:37:53,542 --> 00:37:56,375
the crown jewel of
beachfront homes
722
00:37:56,500 --> 00:38:00,042
can't escape the slow
march of father time.
723
00:38:00,208 --> 00:38:01,833
The glass panels are cracked,
724
00:38:01,958 --> 00:38:05,000
and salt is crusting the facade.
725
00:38:05,167 --> 00:38:07,125
The rain is seeping into seams
726
00:38:07,292 --> 00:38:09,542
that were never meant
to go unmaintained.
727
00:38:09,708 --> 00:38:12,500
The rooftop pool would
be a murky swamp,
728
00:38:12,625 --> 00:38:14,875
by now likely covered
in vegetation.
729
00:38:17,625 --> 00:38:20,167
But, the futuristic
exoskeleton
730
00:38:20,333 --> 00:38:22,374
did exactly what
it was built to do:
731
00:38:22,375 --> 00:38:27,332
absorb stress, flex with
the wind, hold its ground.
732
00:38:27,333 --> 00:38:28,625
The outer shells scarred,
733
00:38:29,000 --> 00:38:31,999
yes, there's cracked glass,
there's twisted metal panels,
734
00:38:32,000 --> 00:38:33,999
there's salt-stained concrete,
735
00:38:34,000 --> 00:38:36,542
but the core structure is sound.
736
00:38:36,667 --> 00:38:39,124
It looks battered,
but it's not broken.
737
00:38:41,625 --> 00:38:44,250
Eventually, perhaps
centuries from now,
738
00:38:44,375 --> 00:38:46,292
the saltwater will
finally eat away
739
00:38:46,417 --> 00:38:49,167
at the building's mighty
cement foundations
740
00:38:49,375 --> 00:38:51,542
and corrode the
steel reinforcements.
741
00:38:54,875 --> 00:38:57,375
500
years after people.
742
00:38:59,208 --> 00:39:01,791
With a massive
crack nobody hears,
743
00:39:01,792 --> 00:39:05,999
the last survivor of Miami's
skyline gives up the fight
744
00:39:06,000 --> 00:39:07,875
and surrenders to her fate.
745
00:39:14,042 --> 00:39:16,667
For millennia, the homes
we built kept us safe,
746
00:39:16,792 --> 00:39:20,250
sustained us, and kept
the elements at bay.
747
00:39:20,417 --> 00:39:21,542
But without us,
748
00:39:21,917 --> 00:39:26,042
nature finds a way to reclaim
everything we once built.
749
00:39:27,167 --> 00:39:30,375
No matter how
well-built, every home,
750
00:39:30,542 --> 00:39:32,000
whether it's nestled
in the suburbs,
751
00:39:32,167 --> 00:39:33,499
built of the strongest stone,
752
00:39:33,500 --> 00:39:35,624
or rising above the sea,
753
00:39:35,625 --> 00:39:39,750
they were built to exist
in a world with us.
754
00:39:39,917 --> 00:39:44,333
And without us, even the
strongest will, in time,
755
00:39:44,500 --> 00:39:45,708
return to the earth.
756
00:39:47,958 --> 00:39:50,458
If alien archeologists
come digging someday,
757
00:39:50,625 --> 00:39:52,083
they might find a few clues:
758
00:39:52,250 --> 00:39:54,208
a warped metal patio chair,
759
00:39:54,375 --> 00:39:56,875
maybe sun bleached,
but still intact.
760
00:39:57,000 --> 00:40:00,333
Just like the tools
found in Egyptian tombs,
761
00:40:00,500 --> 00:40:01,667
bronze chisels,
762
00:40:01,875 --> 00:40:05,250
copper blades buried
for thousands of years,
763
00:40:05,417 --> 00:40:07,832
untouched by moisture,
still recognizable.
