The impact of insects on the natural world is colossal. Without them, 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 would be devastating for the human population.
