Thus, effective environmental protection should be recognized as a long-term economic imperative as well as a value in itself, but restraint should be proportionate to the benefits, however difficult measuring those benefits often is. Similarly, further tort reform could strike a better balance between providing the ability to obtain redress and generating costs that impede competitiveness. More generally, our objective should not be to eliminate all risks, but rather to reduce risk to optimal risk/reward levels.
