As the dominant, multicellular life-form on the planet, the ecological impact of insects is colossal. Without insects performing essential ecosystems services, the Earth would be a very different place and most terrestrial vertebrates that depend on them directly as food would become extinct. The loss of bees alone might cause the extinction of a quarter of all life on Earth. A total loss of insects might see the human population plummet to perhaps a few hundred thousand individuals subsisting mainly on cereals and a few fish.
