FOOD FACTORIES
Green plants are busy factories
That keeps us all alive
Without them we would have no meat,
No honey from the hive.
Though energy from the sunlight
Supplies our every need,
Without green plants to capture it,
Where would we be, indeed?
All day we use up oxygen
With every breath we take,
Forgetting that without the plants,
Our lives would be at stake.
So though we think we’re clever,
Our brains amount to nil
If we forget our livelihood
Depend on Chlorophyll.
