In modern times, their holes got bigger. People are taking more and more from Earth to fill the void inside them.
People will take more and more from Earth, until Earth says "I have no more to give".

Each product takes resources which are taken from mother Earth.
Human is truly the greediest of animals.
Human chooses to destroy the land that gave him birth.
