I don’t think you have any concept of the size of the burning area or the intense weather conditions in the western US. Months of drought conditions then 90mph wind gusts. Once a blaze is going it will jump all over the place due to the wind, making it virtually impossible to contain until the winds start to subside. Cleaning out underbrush can help, but with winds that high fires will jump directly from tree to tree. Some of these fires only took one spark to start. And the conditions will only grow more intense as climate change continues. This is not a problem that’s easy to solve.
Bake my own bread and freeze it all the time. It’s fine in the short term, and fine for much longer term if you vacuum seal. Bread that’s not loaded with preservatives goes bad in a matter of days otherwise, so freezing is just practical.
