The Earth?s magnetic field is showing signs of getting readyto shift, so that magnetic north will point towardsAntarctica and magnetic south will point north. Compasseswill point the wrong way, and migrating birds, fish andturtles will be affected. This won?t be the first time: ithappens about every 500,000 years.

When groundwater comes close to the foundations of the pyramids, the salt in the water weakens the stone and causes structural damage. Dr. Ayman Ahmed, of Sohag University, says, “Probably the most dangerous factors affecting the pharonic monuments are urbanization and agricultural development.”
