Domestic household water use we plan for 160 gallons per person per day. That is drinking water, flushing the john, showers, washing clothes, water the lawn. Everything. Actual is about 100 gallons per day on average. California has tried to knock this down to 48 GPD but uses a lot of gray water for lawns etc. 39.35 million people live in California.

Agriculture has always been big. The number of farms hasn't increased it has decreased as urbanization spreads. 3.4 million acres have been lost to urbanization. cropland loss

Too many people.
