The refugee camp Moria on the Greek island of Lesbos is overcrowded. It is built for 2,500 people, but now hosts about 7,500 refugees. The living conditions are poor with limited access to proper sanitation facilities, medical care, or nutritious food. There are frequent clashes, riots and it is harming the mental health of the refugees. Medecins Sans Frontieres says it is dealing with children as young as 10 contemplating suicide. Every day new refugees arrive on the island.
