Abstract
From those very early days when prehistoric man
gave up his nomadic and predatory habits and began to raise crops
and tend cattle the struggle between nature and man must have com-
menced in right earnest, man upsetting the normal conditions
prevailing in the universe, and nature asserting herself every time to
re-establish her supremacy. Gradually, through centuries of civiliza-
tion, as this protracted struggle continued, one of the most important
changes effected has been a pronounced re-adjustment of the relations
that originally existed between man and the lower forms of lifc. Under
the numerous artificial conditions brought about by human agency.
what is known as the "balance of life" in nature is constantly
upset especially among the lower animals like insects and one of
the various resulting phenomena which frequently happens is an
abnormal increase in the number of some lower forms of life which
affect men-in other words, there is an outbreak of pests. Man has,
of course, recognised this self-inflicted but inevitable evil through
past decades and in all countries.
