>The urban water use is around 20% which means that around $20B/year will cover desalination of all the water consumed in California solving all the environmental issues caused by water consumption, and all those problems probably would become close to nonexistent even if we cover only half the needs at $10B/year. Especially considering that climate change would be making situation only worse, and thus desalination is unavoidable anyway.
