Imagine there's no countries
It isn't hard to do
Nothing to kill or die for
And no religion, too
Imagine all the people
Living life in peace... You...

You may say I'm a dreamer
But I'm not the only one
I hope someday you'll join us
And the world will be as one

John Lennon


Communities require trust and cooperation. We all know this and practice it in the communities which we are part of. 

For humanity to survive into the future we need a way to create one world community with that same foundation of trust and cooperation:

Democracy From Below

We can never know everyone in the world, but we can create a world community in which we can all feel equally welcome. 

Eventually one world community would have no borders or controls on where people are allowed to go or live.
