Earth Wobbling May Cause Extinctions

The Earth wobbles on its axis between 22 and 25 degrees with it currently positioned at 23.5 degrees off "center." Scientists have long theorized that the wobbling had an effect on climate and magnetic fields.

Now some scientists believe that the wobbling may also be responsible for mass extinctions. It may be true or it may not be true; but it is certainly interesting. I have heard other theories with space-caused extinctions. My astronomy teacher from way long ago once pointed out how there seems to be a mass extinction each time the solar systems enters another arm of the Milky Way.

Some environmental geographers like to view the earth as an independent, island-like system. However, even the most remote islands are susceptible to storms and waves.
