The File Drawer Problem

It's so hard to measure any of this. And you can't really just look at it as a whole, either. We know that cockroaches are extremely resilient. They're not going to be affected nearly as much as some of these other species. So if cockroach populations are thriving, while other insect populations are dying off, the total biomass of insects might not be changing at all. It might even be increasing, but we're still going to have all of these negative effects on our crops and on the whole ecosystem.
