42.        The speaker argues that because scientists continually shift viewpoints about how
our actions affect the natural environment, companies should not change their products
and processes according to scientific recommendations until the government requires
/ I$ D' O" s" Pthem to do so. This argument raises complex issues about the duties of business and
about regulatory fairness and effectiveness. Although a wait-and-see policy may help
companies avoid costly and unnecessary changes, three countervailing considerations

      First, a regulatory system of environmental protection might not operate equitably.

requires detection, and while some violators may be caught, others might not. Moreover,
a broad regulatory system imposes general standards that may not apply equitably to
every company. Suppose, for example, that pollution from a company in a valley does

reflect scientific recommendations. However, this claim is somewhat dubious.
Companies with the most money and political influence, not the scientists, might in
some cases dictate regulatory standards. In other words, legislators may be more
influenced by political expediency and campaign pork than by societal concerns.
      Thirdly, waiting until government regulations are in place can have disastrous

regulations are implemented. This problem is compounded whenever government

its detection and enforcement duties, thereby allowing continued environmental damage
by companies who have not yet been caught or who appeal penalties.
