Aftermath: Population Zero

00:00:00 Planet Earth: a place of constant change at the hands of powerful beings:

00:04:11 and the entire city cools down by a fraction of a degree.

00:08:18 Automated systems detect that the electrical grid is failing

00:12:08 an automatic safety feature designed to contain gas leaks at plants.

00:15:36 And they're dangerous.

00:19:38 they need to find some easier prey.

00:23:41 500 times greater than what was unleashed on Hiroshima, will be released.

00:28:01 the size of Alabama.

00:31:14 they have access to food that's much less radioactive.

00:35:10 But cockroaches are imports from the tropics

00:38:58 accounted for half of the impact humans had on global warming.

00:42:35 there's nothing to keep it from falling back where it came from.

00:46:41 Welcome to a world thirty years after humans disappear.

00:50:14 Concrete is strong, but extremely porous.

00:53:59 When people were on the planet

00:57:20 But where there are deer

01:01:09 the river is out of control.

01:04:50 Dozens of dams still hold back the Colorado River.

01:08:51 The water pours over the Hoover dam

01:12:43 Some of the sound from these vessels carried for miles under the oceans.

01:17:34 animals that we left behind have adapted.

01:21:39 After two hundred thirty years

01:25:50 Then, a chain reaction causes ice

45:00:00 pounds of water per square foot.
