What happens to a world when the magnetic poles are shifting? The poles were moving at ten miles a year - now 40 miles a year. They're building seed stores across the globe just in case the planet flips. You get increased earthquakes and volcanic activity - ice sheets melt and reform at the new poles. (sounds like man made global warming?)
So remember when your putting rubbish in your six coloured bins for the recycling people... Your really wasting your time.
don't panic people just sort your rubbish, it'll be okay.
