Does the Earth's magnetic field deplete and not recuperate? If it only depletes, should we worry about it?

no. we should worry about it flipping polarity in the near future.

its inevitable that it WILL deplete, but that will be LONG into the FAR future.
By that time, hopefully we'll have the tech to move to other planets

Yea, the Boy Scouts might get lost in the Smoky Mtns. when their compasses fail.
..
Birds will fly North for the winter killing billions, and Delta Airlines will go bankrupt from a class action lawsuit for delivering 1 million passengers to the wrong destination (during Christmas).
And the guidance system of U S. nuclear tipped cruise missiles will go off course into Moscow creating WW3

Yes, but dont get nervous, the Earth's magnetic field have 1,200 years life left. they are changing because north pole and south pole are changing. means antarctica is currently in s.pole but s.pole will be n.pole and n.pole will be s.pole. but to do this action they have to destroy their magnetic field. just shown in hollywood film ' THE CORE'. so live happy. we are lucky that we cannot see it.

only way it will deplete is if the molten core cools it causes our magnetic feild which keeps us safe for hamful things in space
