I consider myself an environmentalist, and I&amp;#x27;ve also come to recognize that these issues can be complicated.  Progress is made iteratively and sometimes gradually.  While I would love to drop a hammer on the over-fishing of Pacific Salmon for example, when you meet a person who lives in Homer Alaska and lives off of their fishing and you realize that if we completely shut down fishing for a year or two, that person would be economically destroyed.  That&amp;#x27;s just one person in the equation.  There are many thousands more.  There are ways to improve the salmon population without wiping people out or causing major havoc, but it requires people to learn a whole lot more about the issues than what can be reduced to sound bytes.</text><parent_chain><item><author>poulsbohemian</author><text>I took a tour with the Corps of Engineers earlier this week at a dam on the Snake River.
