About Global citizen
Greggory Cates
I built a few successful small businesses and sold the last one in 2004.
I then asked myself “What does someone—who can do anything—do?”
My answer was to dedicate myself to helping others. Over the years, I had read 30,000+ research articles and earned undergrad degrees that gave me a basic understanding of the world around me. I came to the conclusion that the best way to help my species (and the planet we live on) was to design replacement civilizations, a task so hard that it should take me the rest of my life to accomplish. If successful, the ripple effect across humanity could potentially maximize the benefits for us all.
Out of this epiphany, Global Citizen was born in 2003 to create a future where we (and future generations) could live sustainably, in harmony with each other and the world around us.
For me, this was the foundation of Sustainable Civilization Design.
