Question

Is the going on culture of boundries/ boarders is good, i think there is no need for it but a little check is good. Anyone can move freely fron one place to another to gain good knowledge and to choose best place where he wants to live his life easily and according to his own life style. I need diffferent opinions, Please.

Answer 1

Humans, like the animals we are, are territorial. We move in tribes (packs), take over and defend our territories. We decide who we want to let in our territories and who we need to keep out. I am glad we don't pee to mark our boundaries though.

Answer 2

Boundaries traditionally developed because of geographically features. However, as we have become more open as a society and technology now allows us to communicate around the world instantaneously (and visit almost anywhere with a simple plane flight), the need for traditional geopolitical boundaries has started to dissipate (we will never be without borders though, because we as humans feel a need to identify with a group, whether it be those that speak the same language as us, or live nearby).

The European Union has started us on the right path, even though you have many separate countries, almost all with different languages, they now have a common unified currency, and any citizen can travel freely among the unified countries. As the EU gets stronger, and America's own boarder disappears more everyday, I believe that we will start to see the beginnings of an essentially border-less world.
