..if Giardia is a native species, would we be obliged to protect it?...
Good point, wagga. What California needs is an official state microorganism!
Hey, put a giardia on the CA state flag since there ain't no more grizzlies!
Better yet, a cow in lieu of the bear, a giardia in lieu of the star, brown instead of green below the "cow," and "Happy Cow Lives in California Republic."
