Technically the SRKW is evolution at work. A new predator (European origin Humans) has entered the ecosystem, altered the habitat in several ways and over harvested the resource so salmon populations can not be sustained. I guess the difference is as sentient beings, the only ones who utilize technology, are able to realize we are the cause and we have the choice and ability to try and mitigate the damage we have done and not allow the extinction. Certainly many species have been allowed to become extinct due to human activity, so its an argument these whales should be allowed to vanish as well. This wont save the salmon, the whales or seals aren't the cause of the decline, we are.
Transient whales are not competing with residents. Their increase in numbers starting from the 70's has coincided with pinniped populations going back to historical norms. Transients were previously negatively impacted by human killing of their main prey, pinnipeds, so are proof that whale populations can be restored by human actions that restore the ecosystem. Transients aren't going to just instantly replace residents, they have evolved seperately. It would take a long time for some transients to evolve back to fish eating residents if salmon populations were to return. By then Trump or some future moronic Trump like individual will probably have annihilated most life on earth with nuclear weapons, so maybe we just shouldn't worry about any of it![/
Seriously? Trump? This is the mentality that stops discussion and the possibility of improving our fisheries. Why not just blame the Russians
