Life After People

Narrator: Now, without armies of gardeners and repairmen, modern cities are laid bare to nature's revenge.

Narrator: As generating plants go down, outages on the power grid contribute to a cascade of failure worldwide. After a few weeks, the planet is plunged into a deep darkness it has not experienced since humans first huddled around campfires. Perhaps the last glow of artificail lights on Earth will be seen in the American southwest. Here, the mighty Hoover Dam hydropower plant takes little notice of the absence of humans. It's source of fuel is virtually limitless.

Narrator: The disappearance of humans may seem like science fiction, but eventually there will come a day like this. A day when people no longer walk the earth.

Narrator: What would happen if every human being on Earth disappeared? At some point in the future, this could be the fate of our planet. This isn't the story of how we might vanish, it is the story of what happens to the world we leave behind.
