Planetary alignments create physical disturbances in our solar system.
Physical disturbances in our solar system create electromagnetic changes around Earth.
Electromagnetic changes around Earth have a direct effect upon human beings via physical metabolism. They also create physical changes such as climate shift, droughts, floods, volcanoes, and earthquakes. These, in turn, have a direct impact upon human beings and their physical metabolism.
Atmospheric and climate changes on Earth create fluctuations in agricultural production.
Fluctuations in agricultural production create economic changes.
Economic changes create social changes and social changes create political changes.
