The Monterey Bay National Marine Sanctuary extends from north of the Golden Gate to Cambria in the south. Originally intended for the Monterey Bay and it's deep submarine canyons, the sanctuary continually expands. For several years there has been serious talk of joining it to the Channel Islands National Marine Sanctuary. And talk of declaring basically the whole Southern California bight to the Mexican border is gaining support.
Some parts of the MBNMS extends inland and not because of riparian habitat. "They" want control of the public's every movement. Punishable by incarceration and/or a $10,000 fine for removing a rock from the beach, never mind that rock is a grain of sand. It's all there in the regulations.
All this and more can be contributed to a world view which holds some idealized fantasy of a world without people.
