earthquakes. Mother nature has been shaking things up way longer than we have been tampering with her. For instance, they've tied historical records of earthquakes in China/Japan with anomalies in tree rings of ancient trees in Oregon, as well as geological disturbances, suggesting massive tidal waves correlating to the same asian dates.

Thats not to say that 20th century man may not in a small way contribute to some recent tremors, but I think to switch the entire hypothesis to man's intervention is a stretch. Particularly for large earthquakes. Last year there were around 83 earthquakes globally greater than a magnitude 5.0, and thousands of smaller tremors. On the island of Hawaii alone they record many earthquakes every day - most are too small to be felt by anything but a seismograph.

I've always wondered what effect pulling all that oil and water out of the ground is having though. Humans waste so much.
