If only it were that easy ....
We have diverted nearly the entire Colorado River and dried up the Delta. Migratory birds now use the Salton Sea because there isn’t any Colorado Delta left these days. Dry up the sea and where will the birds go?
But what the heck, who cares about some birds, anyway. Let it dry up and all those pesticides & salt & stuff that’s been floating around will cause some pretty bad dust storms.
I am not sure what should be done, but I am not convinced it should take 9 billion to do it.
Maybe to some of the shallow bays in the Sea of Cortez. Birds use a free market model when choosing breeding/feeding sites, and the Salton has not been there that long. It has always been a salt flat or transient lake.
I don’t know what to do either, and I agree that 9 billion is a bit too much.
