Should we stop eating Salmon?

Or, as my grandfather who lived to be 94 used to say, "Everything in Moderation." This op-ed in the New York Times about the depletion of wild salmon is unsettling: http://www.nytimes.com/2008/06/09/opinion/09grescoe.html?ex=1213675200&en=7a1186909233042e&ei=5070&emc=eta1

I'm pretty convinced that if the world population continues to grow, and the earth's people continue to eat more meat and fish and fewer vegetables, and we continue to overeat and waste so much food, our planet is going to have a heck of a time sustaining our eating habits.

For now, I'm going to stick with my philosophy of eating a wide variety of foods in a sustainable manner by buying only what I intend to use, using what I buy, focusing on plant based foods as much as possible, and trying not to overeat, which is an unhealthy form of wasting food.

Let me know if you have any other ideas for sustainable eating.
