What's to stop a landlord from turning a floor in his apartment building into a chicken battery farm now?
Why do you care if they do? Now you should have the right to demand that the chicken farm controls the smell, and otherwise isn't polluting, but stopping chicken farms completely is the wrong solution. The above includes assurance that fire and accidents will not spread. Of course land in the bay is valuable enough that nobody will do what you suggest. However that is economics, it shouldn't be law.
If someone invents a way to do it safely, they should have the burden of safely proving that first.
If someone wants to stockpile 100 tons of explosive material in my neighborhood, I don't want my estate to use the courts to find remedy after my section of the neighborhood gets leveled/cratered. I want the obviously harmful activity to be stopped before the hazard is created.
