A crash course in changing the world.
This is a partial photo of one of the signs in the aquarium that explains how the fishing industry has affected Monterey, the surrounding area, and the ecosystem. The canneries used to grind up the unused fish parts to sell as feed, fertilizer, and so on, but at one point, the demand became so huge that they lobbied to have a law passed allowing them to grind up entire fish for that purpose. For those who don't know, the industry collapsed for a while in the Monterey area due to overfishing. Fishing limits are in place now, some areas are protected, and the fish populations are slowly growing.
