Greenberg was exposed to a lot of the harsh realities of Yupik life, including the high suicide rate and relative scarcity of fish. It seems that while the wild salmon were doing well, so were the Yupik people, as their culture emphasizes their connectedness to nature. Salmon is their main source of food, and many of their practices and habits revolve around the health of the salmon at the time. As the salmon numbers drop, so does their opportunity to practice their culture. Now, salmon are valuable enough that they sell the good ones, receiving packaged meat in return. This is a big change from what it used to be. Greenberg also heard about the high suicide rate in the area, and probably connected that negativity with the conclusion that the Yupik people have a very different position now than they used to. He is probably thinking that as the salmon numbers continue to decline, the Yupik people will be forced to lose even more of their culture and identity, so their futures are as entwined as their past has been.
I do agree with Greenberg to some extent. I think that the future of wild salmon, if dark, will result in a further loss of culture for the Yupik people and mean a definite change for them. If the wild salmon experience a resurgence, I think the Yupik people will have an opportunity to revert in part to their old ways and regain some of the cultural identity they have lost in recent years. However, I would say that the modern world is changing at a fast pace, and even if salmon rebound, I’m sure that the Yupik people will have combined elements of Western culture and their traditions. If the salmon’s future is to decline, I think that some of the Yupik people will adapt to new times and, while losing some of their history, will rebound in a new way that none of us can foresee.
