Attempts to prevent pollution by legislation, economic incentives and friendly persuasion have been met by lawsuits, personal and industrial denial and long delays---not only in accepting responsibility, but more importantly, in doing something about it.It seems that only when government decides it can afford tax incentives or production sacrifices is there any initiative for change. Where is industry’ s and our recognition that protecting mankind’ s great treasure is the single most important responsibility If ever there will be time for environmental health professionals to come to the frontlines and provide leadership to solve environmental...
