Boarders are unacceptable, when you are born onto this planet you naturally have the right to go anywhere you want, because the world belongs equaly to everyone and noone. 

We are like visitors here, for a human lifetime, because this earth doesn’t belong to any one of us, we can not take it with us when we go, so we should of course treat it with care, and behave with the greatest respect for it, like when you are a guest in the house of someone, who you respect the most out of everyone you know or can imagine knowing.
