The food chain. I'm still amazed no one is talking about the fact that insect biomass has declined by ∼47% and abundance declined by ∼61.5% over the last 35  years. In some areas it's measured 75% decline in a single generation. This "insect apocalypse" is...very bad. Don't just take my word for it: "Indeed, most biologists agree that the world has entered its sixth mass extinction event, the first since the end of the Cretaceous Period 66 million years ago, when more than 80% of all species, including the nonavian dinosaurs, perished."
