Not too long ago during the Camp/Paradise fires, just about everyone in northern CA was breathing a toxic cloud of burnt drywall, cars, chemicals, etc. for over a week. Think of the millions of gallons of water wasted, flame retardants dumped, and carbon emissions created. Californians need to live in denser construction near jobs. No more sprawling, low-level construction where fires can easily spread and jump from one building to the next.
