It's a battle about the fish in the sea being waged over Costco by zeppelin!

Regarding Costco, Greenpeace says:

EVERYTHING ABOUT COSTCO is bigger than normal. Costco is the largest wholesale club operator in North America. People shop at Costco because of its bulk goods, low prices, and the wide variety of merchandise available in their giant warehouses. But, while Costco continues to grow bigger and bigger, so does its footprint on the environment. Costco is destroying our oceans through its horrible seafood purchasing practices, leaving its customers in the dark by hiding the truth from them...

...and so forth.
