Decisions made by pollution regulators may impact upon the natural environment, which in
turn may have ramifications for many people. Their determinations affect the ecological
systems that humans depend upon to survive and for their quality of life - the air we
breathe, the water we use and the land that we live on. The consequences may extend
beyond the present generation to future generations as well. Once environmental damage
has occurred it can be a very lengthy, difficult and often costly process to undertake
remediation, assuming it is feasible at all. Some decisions may result in harm so
catastrophic that it cannot be reversed.
