There are three main reasons why technological advances in transportation made migration easier. First, technology made transportation safer. For example, flying from Europe to America is now a lot safer than travelling by boat was in the past. Boats had to deal with many weather problems, as well as disease and lack of supplies. The second reason is that it has made travel cheaper. In the past, travelling to a different country was impossible for many people due to the cost. While travel is not always cheap now, it has become more accessible. Finally, technology has made travel faster.
