Conservatives want lower taxes. Conservatives want smaller government, with less regulations and fewer regulators. Pollution prevention, instead of all the high-cost bureaucratic mandates and regulatory harassment at the tail end of the pollution trail, can achieve those conservative purposes. If you don't discharge it, you don't need to buy a government permit with all the attendant red tape and bureaucratic nonsense to which businesses are now subjected. Pollution prevention corrects not just the physical health of our society, it promotes economic health.
Conservatives believe in individual rights.
We believe in the right to own private property, and to use it as we see fit. Private dry lands should not be deemed to be wet by a remote government. Such actions violate our basic constitutional rights. We conservatives bemoan the decline in values that has besieged our present day society. We abhor government and media assaults on our constitutional right to freely practice our religion in today's value neutral, politically correct society.
