Being a fisherman does not mean you want to catch the last fish, it means you want to keep a good stock
There's a widespread impression among the general public that hunters and fishers want to exterminate a species. They think the massacre of bison was fueled by bloodlust more than politics, they think small subsistence workers are to blame for the consequences of large-scale fisheries and governmental destruction of habitats. The Army Corps of Engineers tried to destroy the Everglades in the name of "progress" and as a subsidy to the cane sugar industry. The government funds recreational beaches with loose non-native sand.
