What Caused the Hole in the Local Salmon Population?

|Baby Coho salmon: worth protecting.|
Why did the salmon disappear so suddenly? The answer isn't just "We ate them all," it turns out -- rather, it has much more with the impact of commercial agriculture on rivers, which prevented a generation of baby salmon from making it back to the ocean after their parents labored so hard to swim upstream to lay eggs. Overpumping, fertilizer runoff, climate change -- all these factors have come together to kill off our local salmon populations. And so the solution, it appears, is going to be just as complex as the problem.
