I happened across this lovely symbol today, which was designed by a man named Dan Poresky. It’s meant to be a universal symbol for environmental awareness. He says this about it:
I designed the ‘One with the Earth’ symbol to serve as an ever-present reminder that it is everyone’s responsibility to ensure a livable world for our children and future generations.
The symbol design represents the Earth, sun (the source of all life’s energy), water (covers 70% of the Earth’s surface), land (30% of the Earth’s surface), and life.
