what is migration

Migration is the process by which individuals or groups of animals, birds, or humans move from one place to another, typically over long distances. It is a natural phenomenon that occurs in response to various factors, such as changes in climate, access to resources, or better living conditions. Migration can occur voluntarily or involuntarily and can be temporary or permanent. Humans generally migrate due to economic or social reasons, such as searching for better job opportunities or to escape war, persecution or extreme poverty in their home country.
