To be honest, it's hard to imagine. You take the species that has all sorts of impact and you just look at what happens if all its interactions with other species....
I just want to allude a little bit to the previous question, in the sense that we don't know. It's like a ball of yarn. You actually don't know all the interactions of a species or its impacts on an ecosystem sometimes until you try playing around with it, whether by having a species go extinct or by actively removing a marine mammal through culling. It's not something that we support, because you absolutely have no idea how it's going to impact the ecosystem. You could put a dozen scientists in a room who would come up with different scenarios for the impacts of removing an apex predator, but the reality is that it would change the ecosystem completely.
What species would come in to replace the southern resident killer whale if it weren't there? At the end of the day, it's not something we want to imagine. It's not something we want to spend a lot of time talking about. We want to spend more time talking about the immediate actions we need to take today to ensure that we don't have to tell our grandchildren what southern resident killer whales used to do and how they looked.
