How can I show "Change the World" in a picture?

A woman covered in diamonds hugging a woman wearing rags......a soldier in full battle uniform comforting an elderly person....a man holding the scales of justice in one hand and supporting a starving child in the other.....a person in a business suit picking up trash by the side of the highway.....pictures from Katrina....from 9/11, normal people doing extraordinary things....or, more simply still, a nurse/ doctor treating someone by the curb.

a symbol of change is a butterfly. so at the bottom left of the poster it starts as a cocoon an moveing up towards the top right it ends up being a full butterfly but instead of traditional butterfly markings an texture it is "skinned over" with images of the globe from like outter space, you know like land masses an clouds , reconizible globe markings . ok now my paypal account which you can send me my money is..... ;)

You could draw a globe with funky colors and bad things on it, like skull and crossbones signs, cigarettes, etc. and then draw a normal looking globe (green and blue) with things like happy faces and food.
