"The environment has to be balanced against the economy." This quote portrays environmental concerns as a luxury, views measures to solve environmental problems as incurring a net cost, and considers leaving environmental problems unsolved to be a money-saving device.

In caring for the health of our surroundings, just as of our bodies, it is cheaper and preferable to avoid getting sick than to try to cure illnesses after they have developed.
