We have subjected enormous numbers of people to contact with these
poisons, without their consent and often without their knowledge.

We have allowed these chemicals to be used with little or no advance
investigation of what they will do to soil, water, wildlife, and man
himself.

Future generations are unlikely to condone our lack of prudent concern
for the integrity of the natural world that supports all life - urban
as well as rural.

Museums are full of the bones of creatures that have disappeared
from the earth merely because their environment was no longer suitable

Agencies concerned with vector-borne disease are at present coping with their problems by switching from one insecticide to another as resistance develops. But this cannot go on indefinitely, despite the ingenuity of the chemists in supplying new materials. Dr. Brown has pointed out that we are traveling "a one-way street". No one knows how long the street is. If the dead end is reached before control of disease-carrying insects is achieved, our situation will indeed be critical.

With insects that infest crops the story is the same.
