HASHTAG LESBOS. The current refugee crisis is the biggest challenge the European Union has ever been facing in sixty years of European integration policy. Some describe it as task of the century. More than 250,000 people have reached Greece in 2015, the vast majority of them Syrians or Afghans fleeing conflict. The moment the refugees arrive at the shore is absolutely dramatic: the arrivals cry, scream, collapse, but also laugh and sing, take selfies and call their relatives. It is an emotionally overwhelming situation. How many boats arrive depends on weather, patrolling coastguards, the political situation and the smugglers' time schedules. Sometimes more than thousand refugees arrive, another day only a few boats reach the shore.
