The Sahara desert, once seen as a barrier between Europe and Africa, is increasingly becoming Europe's southern border, as the effects of climate change and population growth in Africa are causing people to migrate north in search of a better life. This migration is putting pressure on European countries to tighten their borders, leading to increased tensions between the two continents. The European Union has been working to stem the flow of migrants, but the underlying causes of migration, such as poverty and conflict, remain unresolved. As a result, the Sahara is likely to continue to serve as a frontline in the struggle between Europe and Africa.
