If you think about it, there should be no countries or boundaries. The planet is not ours, despite our sense of entitlement. We do not own the land.
We belong to the land and not the other way around, and Life has a way of reminding us of who is boss. Ultimately, the ground will reclaim all of us.
Life is for living, enjoying, sharing and learning from one another. Life is not for bickering and fighting over that which does not even belong to us in the first place.
