We think we rule the world, but doesn't the world really rule us?
Humankind has managed to achieve things thought impossible in years gone by, but we will never be able to triumph over nature. It will always hold tremendous power over us. The most advanced and superior of cities could be wiped out by an earthquake in an instant; the world's most powerful leaders could shiver when thunder rolls overhead; thousands could die when a tsunami hits.
No matter how infallible you think you are there's always going to be something that knocks you off your pedestal.
