If neighbor 1 creates a 200' treeless buffer zone around their home, and neighbor 2, 3, 4 .......all do the same, you effectively need to remove all trees from entire cities. You effectively create a desert that nobody would want to move to.Engineers disagree that there is nothing we can do to avoid fire losses.
Trees do not have to be eliminated. But groves of trees can be far enough away from structures so they are not a threat.
Same goes for powerlines and power stations. There is talk about this fire originating from a power station failure.
Building codes can be enhanced so houses are not tinderboxes.
(there are single trees beside houses that still stand.... but the house is ashes)
The issue is that nobody wants to pay for it on the front end.
