"The Earth reminded us of a Christmas tree ornament hanging in the blackness of space.As we got farther and farther away,it [the Earth] diminished in size.Finally it shrank to the size of a marble,the most beautiful you can imagine," Irwin said."That beautiful,warm,living object looked so fragile,so delicate,that if you touched it with a finger it would crumble and fall apart.Seeing this has to change a man."
