Some theorize that urchin barrens are natural to the ocean as forrest fires are to the land.
"Back in the "early days" (50's-70's) the urchins that truly threatened kelp forests were receiving "supplemental" food in the form of untreated human wastes that allowed them to survive in the barrens after decimating the kelp."
I haven't heard that urchins eat human waste, I assume you mean "human feces", before. Do you have a cite for that, please?
