Migration

Migration - Migration is the movement of people and things from one place to another.

Barriers to migration are things that slow or stop the movement of people and things from one place to another.

Physical Barriers

– Physical Barriers include mountains

– Vast expanses of places that are too cold such as tundra or too hot such as deserts discourage the movement of populations.

– The vast expanse of oceans on both sides of the United States discouraged Europeans and others from invading North America.

Economic Barriers

– Economic barriers to migration include poverty and high unemployment.

– Economic decline often encourages further decline.

Political Barriers

Migration also applies to fauna. For example, an interstate could be a barrier for migratory animals. Sometimes a large engineering project becomes a migration barrier - for example the Panama canal that is completely isolating North and South America.
