For my final project for SICK!, I chose to experiment with moss graffiti. The social determinants of health that this addresses are physical environment and air quality. This is because moss absorbs CO2 and acts as an air filter,  removing soot, dirt, and other pollutants from the air. 

If you decide to make your own moss graffiti, you can print this out and wheatpaste it nearby to share the process with anyone else who'd like to try!

To make moss graffiti, collect a good amount of moss (1-2 cups) and rinse it to get all the dirt off. Blend the moss and yogurt together until they turn into a creamy, paint-like substance (you might need to add a bit of water). There are a number of different recipes for moss graffiti online but I've found that the simplest ones work best. You'll need to return to your moss graffiti every couple of days until it is fully sprouted to spray it with water or paint over it to ensure it retains moisture. 

Unfortunately, I've only recently figured out (what I am hoping is finally) a successful recipe so the moss hasn't started to grow yet, but I will update with photos of the moss as soon as it is visibly growing!
