Although, we can trace migration movements all along the entire humanity's history, there has been alwasy very contradictory points of view regarding this subject. Nowadays, there are people that still believe that migration is a negative phenomenon for the development of their own countries while others sustain that it is anything but negative, because besides to be a natural process it allows economic and social strengthening. In the present dissertation, I'd like to suggest why all of us should support and encorage migration. In order to do it, I'll present a couple of arguments and examples, as well as to draft some conclusions.
