An example of how population changes shape global interactions is the refugee crisis in Europe. Worldwide population movements are occurring due to wars and unrest in the Middle East and North Africa, leading to an influx of over one million refugees into Europe in the last four years. This has had a wide-reaching impact on the global economy, politics, and social fabric of the continent. Additionally, the debate surrounding how best to handle the influx of refugees has spilled into the public sphere, leading to an increase in racially motivated hate speech, discriminatory laws, and civil unrest in many European countries. This development is important for 9th grade geography students to be aware of and shows how population changes, especially when happening on an international scale, shape global interaction in today’s world.
