Also: medicine from microbes, giving back to the land after extractive processes, collecting samples in urban rivers, elders’ ecological knowledge, planting hot Cheetos, potting soil mysteries, lung fungus, the smell of rain and why gardening makes you happy. Oh and running hundreds of miles for your science.
