Explanation / Answer

1. Economic growth is the major factor behind alien invasion. This is supported by global transport facilities. It has become easy to reach any part of the world and its not expensive to move from one part of the world to another. Trade between nations in terms of essential commodities or even movement of people has increased drastically in the past few decades. With the ease to reach any place in such less time has enhanced movement of alien species.
