Images of suffering can bring about change – but are they ethical?

In a series of provocative photographs, poor children in India were made to pose in front of fancy tables covered with fake food. A prize-winning Italian photographer, Alessio Mamo, took these pictures in 2011, as part of a project called “Dreaming Food.” After the World Press Photo Foundation shared the photos on Instagram, they sparked a bitter controversy. Many considered them unethical and offensive.
