Gaia is one of my main deities, though I don't consider her a patroness. In all honesty, I consider her my grandmother and the grandmother of all humans (well, great-grandmother if you consider the Olympians the creators of the human race). Most of my activities in her honor are mundane in nature. Picking up trash and litter out of nature centers and local parks, recycling, using eco-friendly and natural products whenever possible, etc. I also do rituals to help heal her.
Gaia is fantastic to work with if you have a poor body image or if you have an eating disorder
