From 16 to 21 December, we set up our "Why #LeaveNoOneBehind" exhibition at the Paula-Fürst-Gesamtschule in Berlin. The exhibition is about the inhumane and violent EU migration policy using the example of the former Moria camp on Lesbos. In powerful pictures, drawings and short texts, we give an impression of life and resistance in the camp. We explain which political developments have led to the catastrophic situation at the European external borders. And we show what alternatives in solidarity look like and encourage people to stand up for the right to freedom of movement for all people. During tours with different classes, we asked the young people, among other things, "What do these images of the European external borders have to do with us?"
