Answer:
Socio-political, economic and ecological factors are the main forces driving migration. Rising communal violence world-wide, often as a result of ethnic or religious intolerance, has led to increased levels of migration. Economic disparity between developing and developed economies encourages the movement of skilled labor from the former to the latter. Temporary migration visas allow for an increase in the rate of circular migration. Changes in the ecological environment have the potential to worsen food and water insecurity in various parts of the globe. Limited access to food and water resources may push people to migrate to countries where these resources are more readily available.
