Probably wouldn't wipe out life as we know it. Navigation by compass would be pretty difficult, and it would be hard on migratory species that are thought to use the magenetic field to navigate (or so I've heard, haven't read too much on that). |
I think there will be a huge impact on the environment. If just one animal species goes extinct it can upset everything.
For example the lobster population would go down since they use the magnetic field as a guide to get back into the protection of their hole in the reef/rocks before daylight. Its difficult to say how this would effect some marine environments...
