Now it's been ten thousand years
Man has cried a billion tears
For what, he never knew
Now man's reign is through

But through eternal night
The twinkling of starlight
So very far away

— Zager and Evans, "In the Year 2525"

As any high school student knows, the surface of the earth is composed
of plates that have a tendency to move through time. Thus there has
been a substantial change in the landforms of the earth since the earth
was young. This process continues today — you can feel it in every land-
based or oceanic earthquake.

Personally, I would give our planet 100 more years until complete
environmental collapse. And homo sapiens I would give maybe
another one hundred years after that. (I know, I'm such an optimist.)

But whatever happens, the Earth will go on. With or without us.

Early Pre-Cambrian, ~ 650 million years B.P.

The first life on Earth would shortly follow.

Early Carboniferous, ~ 350 million years B.P.

Early Jurassic, ~ 195 million years B.P.

There were dinosaurs in Canada at this point.

Last Glacial Maximum (LGM), ~ 18,000 years B.P.

In Europe, this time was represented by a culture
called the Solutrean.

Future Earth, ~ 50 million years A.P.

Notice that the Mediterranean Sea no
longer exists.
