question about bugs bla bla bla?

[Steve]

if every single bug and insect in the world died what effect would it have?
i hate bugs i wish this would happen as long as the human race survives of course xD

-->The success of fertilization of flowering plants decrease.They need agents to fertilize the stigma with pollen(Though self-pollination still occurs)

-->No more food for certain animals that depends 100% on insects.They died and eventually extinct.

Take care.
