This is a powerful idea in which the viewer relates to the damage they cause through their contribution of trash.
Photographer Gregg Segal set out to make the trash problem difficult to ignore. He asked friends and neighbours to save their trash for a week and then to lie down among them and get photographed. Getting people including his family to participate helped them realize that they also contribute to this problem.
