Many insects are valuable as predators of
other harmful species, and some are
important as scavengers and as “tiller’s”
of the soil.
Insects are the source of useful products
such as honey, beeswax,& silk.
They are a major source of food for many
animals.
Some people even EAT insects in many
parts of the world.
We could DIE if
there were no
bugs left in the
world!!!

without insects to
pollinate flowers, the
human race would
soon run out of food
because many of the
crop plants that we
rely on would not be
able to reproduce.
