This is a simple image with a clear message. On the left we can observe, a rich aristocrat using a huge tank of biofuel to put gas in his mercedes-benz while on the left there are three malnourished people asking for food.
This image depicts one of the major issues of today's society: greed. The man could have easily used some of his money to help others who are dying from hunger, but instead he decides that his car is more important. Cars are material thing that don't last forever. Lives are meant to be saved. So help others instead of caring only about yourself.
