Roughly 80 % of Earth’s plants are angiosperms (flowering plants), meaning they require pollination from pollinating insects such as bees and butterflies. Further on, between 50 and 90 % of the human diet comes from flowering plants, such as grains, wheat, rice as well as fruits and vegetables.

Moreover, some of these foods are fed to animals that we eat, and you can probably guess where this is going. In short, the gradual and even sudden extinction of insects will cause a nasty chain reaction that will render all life nill. To top it all, after we’ll all inevitably succumb to starvation, the Earth will be turned into a massive, stinky mass graveyard, as insects play a vital role in the decomposing process.
