8. Can migrations have a positive impact on the people and/or land receiving the immigrants?

Migrations have a positive impact on the people and/or land receiving the immigrants because of many things. First of all, a civilizations that welcomes immigrants means many different cultures or ethnics of people living together. Each culture or ethnic group has something special to offer, or introduce. A civilization located in Afroerasia for example would be a many mixed group with traditions, foods, resources, etc from all over Africa, Europe, and Asia. With more resources available the people welcoming the immigrants would be able to excel in innovations. This thus would have a positive affect on the people receiving these immigrants. Land wise as well, the new people would come baring new ideas regarding harvesting and irrigation techniques that could benefit the lifestyle of the receivers. An example of this can be seen in Rome with the aqueducts, other civilizations such as India and Persia also adopted these watering techniques that proved quite useful.
