the problem with destruction is that it depends how you interpret it, there are people who think a fisher is a destroyer. as he takes fish from a fishstocks and removes biomass out of an ecosphere.
If the fish are ocean fish, stocks wil be replenished naturally. If they are hatchery fish, the hatchery feeds the fish. No destruction.
Even if the ocean fish are fished out of existence, they really aren't. There are tiny pockets of them that will grow back. But it might take decades.
Ocean fishing laws simply keep certain fish available so that they can be fed to people at greater cost. It makes more money for the commercial fishermen.
