Consider this :
We are now experiencing a DANGEROUS shortage of bees !
(we can lose wasps and hornets to exinction, and the eco system would be damaged, NO MORE than what the loss of any predatory species causes).
BEES however, they have one of the MOST essential roles in our eco system, and we CANNOT survive without them !
When bees go, we ALL go the same direction !
Plants use photosynthesis, to produce food.
This involves them breathing in CARBON DYOXIDE, and taking in SUNLIGHT, and producing OXYGEN.
We as Animals, (humans are animals) , breathe in the OXYGEN produced by PLANTS.
Plants, like ANY OTHER LIVING ORGANISM has a lifespan.
BEES are responsible for the sex life of a plant (reproduction)
Male plants produce POLLEN
Female flowers take in POLLEN.
Bees transport this pollen, and collect nectar from the flowers !
When plants are pollenated, they produce seeds, these seeds, then fall to the ground, and germinate.
This produces a new plant !
No bees = no new plant !
no new plants + death of old plants = no more oxygen !
So I believe that pesticides should be banned !
