There’s actually stuff being done about preventing Wildfires in the US, controlled burns being of these things, creating “fuel breaks” (gaps that prevent fire from progressing) is another, and there’s a LOT more. But a lot of time that’s not enough and the reason for that is like with every other government effort - bureaucracy and endless paperwork. It can take months before a project can even start because the forest management has to compile all the necessary paperwork. But they are really passionate about doing this to prevent as many wildfires as possible.

Source: I currently work for a startup that makes software that shortens the time necessary to prepare this paperwork which potentially could cut the time it takes in half or more.
