The assault on the purity of the environment is the price that i pay for many of the benefits of modern technology. For tit advantage of automotive transportation we pay a price in smoginduced diseases; for the powerful effects of new insecticides, pay a price in dwindling wild life and disturbances in the relation of living things and their surroundings; for nuclear power, we risk the biological hazards of radiation.
