We're all going to die!

according to the Governor and Westlands in response to new rules protecting salmon, steelhead, green sturgeon and killer whales from extinction,

Westlands Water District called the new rules, "a death sentence for
large parts of California's economy."
"This federal biological opinion puts fish above the needs of millions of
Californians and the health and security of the world's eighth-largest economy,"
Gov. Arnold Schwarzenegger said in a statement. "The piling on of one federal
court decision after another in a species-by-species approach is killing our
economy

Actually, the Valley is currently awash in surplus crops, especially milk and almonds. The human species will survive just fine with a little less food production in the Valley. (and many farmers will be better off too, although there are certainly some that will lose and they are the one's screaming the loudest)

The fish vs. people argument is wrong. Protecting salmon from extermination in California is very much in the interest of people and has great economic value.
