Seagrasses are vital to the marine ecosystem, where they provide food, habitat, shelter and other services for humans and aquatic organisms.

Urine, it turns out, includes two key ingredients in plant fertilizers: phosphorus and nitrogen. Even better, wastewater treatment facilities already process this abundant resource and create byproducts that would otherwise be sent to the landfill.
