People tend to forget what real immigration is, and what good it had brought the world entirely. Yes, it is true it also brought a lot of no good issues. Important is to find out the why and the reason behind all this.
A nomad (Greek: νομάς, nomas, plural νομάδες, nomades; meaning one roaming about for pasture, pastoral tribe) is a member of a community of people who live in different locations, moving from one place to another. Among the various ways nomads relate to their environment, one can distinguish the hunter-gatherer, the pastoral nomad owning livestock, or the “modern” peripatetic nomad. As of 1995, there were an estimated 30–40 million nomads in the world.
Nomads are extremely interesting and very intesting is that there are still many people taking this tradition in place.
