I believe that vegans have made a strong point that humans can live reasonably well without any animal-derived foods and other materials, so a mass extinction of animals would not destroy our way of life. The same goes for pollinators - while there are many commercially important plants that rely on pollinators (e.g. almonds as one of main exports of California), the staple crops that feed humanity - wheat, rice, corn, potatoes - do not require pollinators and would be viable even if all insects died. So even the horrible ecological disaster scenarios threaten human wellbeing and comfort, but they don't really threaten the existence of humanity; fucking up our ecosystem would be a great cultural loss but industrialized farming could still march on.
