Precautionary Principle Working Group

Aldo Leopold stated in his book A Sand County Almanac: "A thing is right when it tends to preserve the integrity, stability, and beauty of the biotic community. It is wrong when it tends otherwise." The precautionary principle provides an approach to decision making to protect the human and ecological community.

The foundation of the precautionary principle can be expressed as the common-sense advice to "err on the side of caution." The principle is based on a desire to prevent harm to the environment, human health, other living creatures and ecological systems. It is intended to apply to a range of situations that involve both a threat of harm as well as scientific uncertainty.

A widely recognized definition of the precautionary principle is from the Wingspread conference: "Where threats of serious or irreversible harm to people or nature exist, anticipatory action will be taken to prevent damages to human and environmental health, even when full scientific certainty about cause and effect is not available, with the intent of safeguarding the quality of life for current and future generations."

The precautionary principle includes the following key components:

  1. Taking anticipatory action to prevent harm in the face of scientific uncertainty.
  2. Exploring alternatives, includ ing the alternative of "no action."
  3. Considering the full cost of environmental and health impacts over time.
  4. Increasing public participation in decision-making.
  5. Shifting responsibility for providing evidence of safety to proponents of an activity.

This group focuses on incorporating precautionary language in the comprehensive plans for King County and Seattle.
