"Home is a people, not a place. Move to a different city, and anyone from your hometown will feel like family. Move to a different country, and the very sight of someone from your native country will make you emotional. Move to space, and the very sight of earth will wreak tears of joy.

We keep bickering over trivial things like race, religion, gender, sexuality, status and so on, because even in this day and age we still take human life for granted. Ask an astronaut, and they'll tell you, whether they can find any trace of those prehistoric barriers from up there in space."

Thus speaks the humanitarian scientist.
