Migration
means to leave their hometown or country and move to another place to study,
work, or to reunite with their families, which has changed the demographic
make-up of many towns, cities, and countries.
Migration can also be due to better educational opportunities, due to
political unrest, natural disasters, war scenarios, or due to polluted
environments.
Due to migration, the boundaries in between the nations and states are
diminishing as the concept of globalized labor is increasing which connects
the countries at different levels of economic development.
Mass migration indicates migration of large groups of people from one
geographical area to another one.
The primary danger of mass migration is that it could lead create a
hospitable environment for the entry of criminal aliens or terrorists into a
country.
