B O R D E R S
While watching Daniel Ratcliffe in Imperium, I noticed a question on Facebook: "If you could remove one thing from Earth, what would it be?" Now that movie about the white supremacist movement might prompt me to want to remove them, but they are only a symptom of a far deeper problem: Borders dividing countries, and thus also dividing people.
Just watch Earth from outer space: no borders there, just a beautiful blue globe full of water and humans, who are 'bags of mostly water' too. That is the apt description an alien gave of us in a movie (can't remember which one)
