The Rise of Nationalism

As evidenced by the Brexit vote in England and the success (hopefully transient) of Donald Trump's Candidacy, nationalism is on the rise across the globe, especially in developed Western countries.  This movement seems to have its roots in the inequalities of globalization and the fear of immigration (especially in light of recent terrorist attacks).  Of course, racism and religious zealotry are at play as well.

Unfortunately, some politicians are taking advantage of the anger, fear and intolerance, placing emphasis on the risks of globalization and promising to protect legal citizens from the dangers of immigration, trade agreements and "cultural dilution."  Older, less educated and more provincial individuals, many having lost their jobs to outsourcing and failing industries (e.g. coal mining, manufacturing, textiles), are most receptive to their message.

While some of these inequities and concerns are legitimate, globalization is here to stay and international cooperation is vital in our efforts to assist developing countries, to prevent war and to combat the threats of pollution, ecologic degradation and climate change.  In the end, we must address the problems associated with globalization without resorting to nationalism; otherwise, we will destroy both our economy and our planet.

Eulachon

Eulachon are small marine fish (8-9 inches in length) that feed on plankton in the eastern Pacific, from Alaska to northern California.  In late winter, they move into estuaries and coastal rivers to spawn; most adults die after this process.  Fertilized eggs, which sink to the gravel beds, hatch in a month and the fry head to sea; there they will live in offshore waters for 3-5 years before returning to spawn.

Heavily laden with fat, the spawning eulachon are known as candlefish (since dried specimens can be lit like candles) and were called "salvation fish" by Native Americans of the Pacific Northwest since their calorie-rich bodies provided vital nutrition during the leans months of late winter and early spring.  Of course, Steller's sea lions, dolphins and sea birds also welcome their spawning runs.

Unfortunately, eulachon have all but disappeared from the coastal rivers of northern California, Oregon and Washington and their numbers have decreased significantly farther north.  Global warming, overfishing, water pollution and altered river sediments (due to hydroelectric dams) are all thought to be playing a role in the population decline of this smelt.
