This photomosaic represents a picture of a starving child's hand in the hand of an NGO worker. The picture is made up of small pictures of food and wants to highlight the problem of throwing away (one-third) of our food while 6 million children die of starvation every year. Two have died during the time you read this. In addition, obesity is becoming one of the largest global health problems, costing the US economy 100 billion dollars a year and killing 400.000 people (in the US).
