Yes and no. If that's literally allmit does and it doesn't do it to an extreme amount i'd have no issues with it, but it also points to it possibly causing other effects that we need to be looking for and studying so we don;t get caught unaware of it destroying ecosystems that we depend on for our lives too. You have to remeber that we don't exist in isolation drom the environment and if it causes that in fish, it might be causing other problems in us, or in plants and animals that we depend on directly or indirectly.
