When we look at the overhead shots of these forests after they've been infested, it's pretty clear to the naked eye which trees are sick and which ones aren't, so presumably there are technological measures that could be used at a certain stage in the life cycle of the beetle to establish where they are. Why haven't the tactics that are being used in New Brunswick been used in British Columbia, and now Alberta, to target areas of infestation? Shouldn't we just be harvesting all these trees regardless, so they don't become fuel for the massive forest fires we've seen?
