I believe the water treatment plants and ag runoff combined with muni runoff are one of the main culprits of the decimation of my beloved Sacramneto River estuary, the largest on the Left coast. But with anything lese, it is multiple causation. Of many of the native species, we have less than 1% of what existed 30 years ago. They spray paint do not dump toxics with a outline of a fish in front of our storm drains. I'm sure that stops everyone.

I showed photos of a beaver pond that was there for probably hundreds of years. Right after they put a new subdivision in and tied off all of the drainage to one outlet pouring in, the beavers abandoned it and moved less than 100 yards upstream. And this is a protected Nature reserve. Everybody has thier socially required nice green lawns though. Urban sprawl and nature rarely coexist in harmony. Politicians play the blame game and point fingers and make mean faces while getting reelected by funds from the same environmental rapists. Hey the bright side is they opened up Pacific Salmon fishing for a week or two this year, yippeeee!!!!
